What is the main function of the spleen?
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.
What are 4 functions of the spleen?

- Filters blood by removing cellular waste and getting rid of old or damaged blood cells.

What are the functions of the spleen?
- Clearance of microorganisms and particulate antigens from the blood stream.
- Synthesis of immunoglobulin G (IgG), properdin (an essential component of the alternate pathway of complement activation), and tuftsin (an immunostimulatory tetrapeptide)
What is parenchyma in spleen?
The splenic parenchyma consists of lymphatic follicles and reticuloendothelial cells, surrounding the arteries (‘white pulp’) and an interspersed network of vascular sinusoids (‘red pulp’).(1) The ratio of white to red pulp increases with age due to accumulated antigenic exposure and stimulation.

What is a Splenule?
Splenules are congenital foci of healthy splenic tissue that are separate from the main body but are structurally identical to the spleen, derived from mesenchymal buds on the left side of the mesogastrium and commonly seen in or near the tail of the pancreas.
What is the parenchyma?
parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions.
What happens if your spleen ruptures?
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.
What is the function of the spleen in the lymphatic system?

What are the functions of the spleen in the body?
Your spleen: 1 Filters out and destroys old, damaged blood cells 2 Prevents infection by producing white blood cells (lymphocytes) and acting as a first line of defense against disease-causing organisms 3 Stores red blood cells and platelets, which help your blood clot
How does an enlarged spleen affect your health?
An enlarged spleen affects each of these vital functions. As your spleen grows larger, it filters normal red blood cells as well as abnormal ones, reducing the number of healthy cells in your bloodstream.
What happens to red blood cells in the spleen?

Healthy blood cells simply pass through the spleen and continue to circulate throughout your bloodstream.
Why is the spleen protected by the rib cage?
Because the spleen is protected by the rib cage, you can’t easily feel it unless it’s abnormally enlarged. The spleen plays multiple supporting roles in the body. 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.
