Spleen : Detailed Explanation


 What is Spleen?

It’s a small organ located just below the ribcage, and it’s responsible for filtering our blood. Although most of us don’t think about our spleen very often, it’s actually a really important part of our body.

Spleen is a small, dark organ located in the upper left quadrant of the abdomen, directly below the stomach. It is about the size of a fist, weighs about one-and-a-half pounds, and contains a number of blood vessels and lymph nodes. The main function of the spleen is to filter blood and remove damaged blood cells.

Spleen structure

The spleen is the largest lymphoid organ in the body and is located in the upper left region of the abdomen, beneath the diaphragm and next to the stomach. It is protected by the rib cage. The dimensions of an adult spleen are approximately 12 cm in length, 6 cm in width and 3 cm in thickness, with a mass of 150-200 grams .  Its main functions are to store platelets, to produce and store red blood cells and white blood cells, to recycle iron, and to serve as a filter for antigens and bacteria in the blood .

There are  parts of the spleen. They each do specific jobs. The sorts of tissue inside the spleen are:

  • White pulp: As a part of the immune gadget, the white pulp produces white blood cells. These blood cells make antibodies. Antibodies fight infection.

  • Red pulp: The red pulp acts like a clear out. It removes waste from the blood and gets rid of antique or damaged blood cells. Red pulp also destroys microorganisms and viruses.

Lymphatic System function

The lymphatic system is a crucial part of the body's immune and circulatory systems. Its primary functions include:

  • Immune Response: The lymphatic system plays a vital role in the body's immune defense by helping to identify, filter, and fight off harmful pathogens, such as bacteria, viruses, and other foreign substances. Lymph nodes, which are small, bean-shaped structures located throughout the body, contain immune cells that help detect and destroy these pathogens.

  • Fluid Balance: One of the main functions of the lymphatic system is to maintain fluid balance in the body. Blood plasma leaks out of capillaries into the surrounding tissues to deliver nutrients and oxygen to cells. The lymphatic system collects excess fluid and proteins from these tissues and returns them to the bloodstream. This prevents the accumulation of fluid and helps prevent tissue swelling, known as edema.

  • Nutrient Transport: The lymphatic system is involved in the absorption and transport of dietary fats and fat-soluble vitamins. In the small intestine, specialized lymphatic vessels called lacteals absorb dietary lipids and transport them as a milky fluid called chyle to the bloodstream.

  • Waste Removal: The lymphatic system also helps remove cellular waste, toxins, and debris from the tissues. It transports these waste products to lymph nodes, where they can be filtered out and eliminated from the body.

  • Transport of Immune Cells: Immune cells, such as lymphocytes and macrophages, travel through the lymphatic vessels to reach various parts of the body where they are needed to mount immune responses against infections or abnormal cells.

  • Cancer Detection and Spread: Lymphatic vessels can play a role in the spread of cancer cells. Cancer cells can enter lymphatic vessels and travel to nearby lymph nodes, potentially leading to the metastasis of cancer to other parts of the body.

Overall, the lymphatic system acts as a drainage and filtration network that helps maintain the body's fluid balance, supports the immune response, and aids in waste removal. It is closely intertwined with the circulatory system and is essential for maintaining the body's overall health and well-being.

Spleen Problems

Spleen problems can encompass a range of medical conditions that affect the normal functioning of the spleen. The spleen is an important organ located under the ribcage on the left side of the body, near the stomach. It plays a significant role in filtering blood, removing damaged blood cells, storing platelets, and supporting the immune system.

Here are some common spleen problems:

  • Enlarged Spleen (Splenomegaly): This condition occurs when the spleen becomes larger than its normal size. It can be a result of various underlying causes such as infections (like mononucleosis), liver diseases (like cirrhosis), blood disorders (like leukemia), and certain inflammatory conditions.

  • Ruptured Spleen: A ruptured spleen is a serious medical emergency. It can occur due to trauma to the abdomen, such as in car accidents or sports injuries. Symptoms can include sharp pain in the left upper abdomen, tenderness, dizziness, and even internal bleeding. Immediate medical attention is required.

  • Spleen Infections: Infections of the spleen are usually secondary to other infections in the body. For example, bacteria or viruses causing conditions like endocarditis or malaria can sometimes affect the spleen.

  • Spleen Disorders in Blood Diseases: The spleen is involved in filtering blood, so it can be affected by certain blood disorders. For instance, in conditions like sickle cell anemia, the spleen might get enlarged and function improperly, leading to complications.

  • Splenectomy: In some cases, a surgical procedure called splenectomy might be necessary, which involves removing the spleen. This could be due to conditions like severe trauma, certain blood disorders, or if the spleen is causing significant health problems.

  • Splenosis: After a splenectomy, some splenic tissue might be left behind in the abdominal cavity. This tissue can grow and function, causing a condition called splenosis. While usually benign, it can sometimes cause symptoms.

  • Spleen Cysts or Tumors: Cysts and tumors can develop in the spleen, though they are relatively rare. Some tumors might be benign (non-cancerous) while others can be malignant (cancerous).

It's important to consult a medical professional if you suspect you have any issues related to your spleen. Diagnosis and treatment will depend on the specific problem you're experiencing. Many spleen problems can be managed effectively with appropriate medical care. If you or someone else experiences sudden and severe pain in the left upper abdomen, seek immediate medical attention, as it could potentially be a sign of a ruptured spleen or another serious condition.

Symptoms of a ruptured spleen encompass:

  • A brief heartbeat.

  • Nausea.

  • Dizziness.

  • Pain under the ribs at the left aspect.

How is it diagnosed in the Spleen?

Diagnosing conditions related to the spleen often involves a combination of medical history review, physical examination, and various diagnostic tests. Some common spleen-related conditions that might be diagnosed include splenomegaly (enlarged spleen), splenic infections, and certain types of cancers like lymphomas.

Here's an overview of the diagnostic process:

  • Medical History and Physical Examination: A doctor will typically start by asking you about your symptoms, medical history, and any relevant factors. They may inquire about pain or discomfort in the left upper abdomen, fever, fatigue, and other symptoms.

  • Physical Examination: During the physical examination, a doctor may palpate (feel) your abdomen to check for an enlarged spleen. An enlarged spleen may be detected through physical examination, but imaging tests are usually needed to confirm the diagnosis.

  • Blood Tests: Blood tests can provide valuable information about the health of the spleen and your overall well-being. Complete blood count (CBC) tests can reveal changes in the levels of various blood components, such as white blood cells, red blood cells, and platelets, which may suggest certain conditions.

  • Imaging Studies: Various imaging techniques can help visualize the spleen and surrounding structures in more detail. These may include:

    • Ultrasound: This non-invasive imaging method uses sound waves to create images of the spleen. It can help detect the size and any abnormalities.

    • CT Scan (Computed Tomography): A CT scan provides detailed cross-sectional images of the spleen and nearby organs. It can help identify structural abnormalities and provide information about the density of the tissue.

    • MRI (Magnetic Resonance Imaging): MRI uses powerful magnets and radio waves to create detailed images of the spleen and surrounding tissues. It can help distinguish between different types of tissues and identify abnormalities.

    • Nuclear Scintigraphy/SPECT: These imaging techniques involve injecting a radioactive tracer that is taken up by the spleen. The tracer's distribution can be captured using specialized cameras to assess spleen function and detect abnormalities.

  • Biopsy: In certain cases where a more detailed analysis is required, a doctor might perform a biopsy. This involves taking a small sample of tissue from the spleen for examination under a microscope. Biopsies are often used to diagnose conditions like lymphomas or infections.

Please remember that only a qualified medical professional can provide an accurate diagnosis and appropriate treatment recommendations. If you have concerns about your spleen or any related symptoms, it's essential to consult a doctor for proper evaluation and guidance.

Maintaining a healthy Spleen

Maintaining a healthy lymphatic system is crucial for overall well-being and immune system function. The lymphatic system plays a key role in removing waste, toxins, and excess fluid from the body, while also helping to transport immune cells throughout the body to fight infections. Here are some tips for maintaining a healthy lymphatic system:

  • Stay Hydrated: Drinking an adequate amount of water helps to keep the lymphatic fluid flowing properly and aids in the removal of waste products. Dehydration can slow down lymphatic circulation, so aim to drink plenty of water throughout the day.

  • Healthy Diet: Consume a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Antioxidant-rich foods help combat inflammation and support lymphatic system health.

  • Regular Exercise: Physical activity stimulates lymphatic circulation. Engage in regular aerobic exercises like walking, jogging, swimming, or cycling, as well as strength training and yoga, which can aid in maintaining lymphatic flow.

  • Deep Breathing: Deep diaphragmatic breathing can promote lymphatic flow. Practicing deep, slow breaths can help stimulate the lymphatic system and oxygenate tissues.

  • Dry Brushing: Dry brushing involves gently brushing your skin with a soft-bristled brush. This technique is believed to stimulate lymphatic flow and remove dead skin cells, promoting detoxification.

  • Massage: Gentle massage can encourage lymphatic drainage and circulation. Lymphatic massage techniques are designed to help move lymph fluid through the lymphatic vessels.

  • Compression Garments: Compression garments, like sleeves or stockings, can provide external pressure to promote lymphatic flow and prevent fluid buildup, particularly for individuals with lymphedema.

  • Avoid Tight Clothing: Wearing overly tight clothing can impede lymphatic circulation. Choose clothing that allows for free movement and doesn't constrict your body.

  • Avoid Toxins: Minimize exposure to environmental toxins such as chemicals, pollutants, and synthetic fragrances. These toxins can overload the lymphatic system and hinder its function.

  • Manage Stress: Chronic stress can impact the lymphatic system. Engage in stress-reducing activities such as meditation, mindfulness, yoga, or spending time in nature.

  • Maintain a Healthy Weight: Being overweight can strain the lymphatic system, so maintaining a healthy weight through a balanced diet and regular exercise can support its proper function.

  • Avoid Prolonged Sitting or Standing: If your lifestyle involves long periods of sitting or standing, take breaks to move around and stretch to prevent stagnation of lymphatic fluid.

  • Hygiene Practices: Proper hygiene, including regular bathing and maintaining clean skin, supports healthy lymphatic function by preventing infections and skin issues that can impede lymph flow.

Remember that while these tips can help support a healthy lymphatic system, individual needs may vary. If you have concerns about your lymphatic health or experience symptoms like swelling, pain, or discomfort, it's advisable to consult a healthcare professional for personalized guidance and recommendations.
