Your spleen’s main function is to act as a filter for your blood. It recognizes and removes old, malformed, or damaged red blood cells. When blood flows into your spleen, your spleen performs “quality control”; your red blood cells must pass through a maze of narrow passages.
Does the spleen recycle red blood cells?
The spleen sits in the upper left of the abdomen, protected by the rib cage. It is the largest organ of the lymphatic system — the circulation of the immune system. It recycles old red blood cells and stores platelets (components of the blood that help stop bleeding) and white blood cells.
What are the 3 functions of the spleen?
- Stores blood.
- Filters blood by removing cellular waste and getting rid of old or damaged blood cells.
- Makes white blood cells and antibodies that help you fight infection.
- Maintains the levels of fluid in your body.
- Produces antibodies that protect you against infection.
Does the spleen store red blood cells?
It acts as a filter for blood as part of the immune system. Old red blood cells are recycled in the spleen, and platelets and white blood cells are stored there. The spleen also helps fight certain kinds of bacteria that cause pneumonia and meningitis.What does the spleen do for your body?
The spleen has some important functions: it fights invading germs in the blood (the spleen contains infection-fighting white blood cells) it controls the level of blood cells (white blood cells, red blood cells and platelets) it filters the blood and removes any old or damaged red blood cells.
Does Covid affect the spleen?
Conclusion: Our study indicates that spleen size increases slightly-moderately in the first stages of the infection, and this increase is correlated with the COVID-19 severity score calculated on the chest CT data, and in this respect, it is similar to infections presenting with cytokine storm.
What happens to red blood cells after splenectomy?
However, after a splenectomy the lack of presence of the spleen means this function cannot be carried out so damaged erythrocytes will continue to circulate in the blood and can release substances into the blood.
Which hormone is secreted by spleen?
Other functions of the spleen are the production of opsonins[6], properdin[7], and tuftsin[8], as well as the creation of red blood cells. While the bone marrow is the primary site of hematopoiesis in the adult, the spleen has important hematopoietic functions up until the fifth month of gestation.How does the spleen filter blood?
Blood passes through the cords and into the sinusoids where it is drained into the large trabecular veins of the spleen. Blood is filtered through gaps in the sinusoid lining, which prevents old, damaged or abnormal red blood cells from passing into the bloodstream.
How does the body function without a spleen?You can live without a spleen. But because the spleen plays a crucial role in the body’s ability to fight off bacteria, living without the organ makes you more likely to develop infections, especially dangerous ones such as Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae.

Why do platelets increase after splenectomy?
The early, highly significant thrombocytosis, following both splenectomy and general surgery, is caused by increased production of platelets due to the surgical trauma. This is caused by a direct action on bone marrow MK by transforming 2N-8N MK into higher ploidy classes.
Can Covid cause a ruptured spleen?
Conclusion. The evaluation of the spontaneous splenic rupture (SSR) in our case shows that this type of risk should also be considered in patients with COVID-19 who refer to medical centers with abdominal pain, and if more cases are reported, the correctness of this process can be commented on.
What happens to a ruptured spleen?
A ruptured spleen (a fist-sized organ located in the left upper abdomen) occurs when the surface of this organ is injured, which can lead to internal bleeding. Symptoms include pain in the abdomen and nausea. A ruptured spleen is treated with surgery if the patient has lost a large amount of blood.
Which organ filters red blood cells?
The spleen is located in the upper left part of the belly under the ribcage. It helps protect the body by clearing worn-out red blood cells and other foreign bodies (such as germs) from the bloodstream. The spleen is part of the lymphatic system, which is an extensive drainage network.
What filters red blood cells?
The spleen is like the water treatment plant for the body’s bloodstream. It prevents pathogens from reaching the bloodstream and filters out old and misshapen red blood cells.
What produces red blood cells?

Does a spleen affect hormones?
This regulation seems to be due to the production by the spleen of one or more hormones. These hormones appear to affect the processes of the bone marrow and also may act upon the corpuscles in the circulating blood.
Does spleen have endocrine function?
The spleen is not an endocrine gland. This is because the spleen is not capable of aiding in the regulation of the hormone levels in the human body.

What is red pulp and white pulp of spleen?
The spleen contains two main types of tissue – white pulp and red pulp. White pulp is material which is part of the immune system (lymphatic tissue) mainly made up of white blood cells. Red pulp is made up of blood-filled cavities (venous sinuses) and splenic cords.
What is red pulp composed of?
Red pulp is a loose spongy tissue with chords of reticular cells located between venous sinuses that contains lymphocytes, macrophages, granulocytes, and plasma cells.
