Red pulp filters the blood of antigens and microorganisms.
. If you were to take a cross section of the spleen, you would find that it is separated in to two distinct types of tissue. They are called red pulp and white pulp. I'll give you one guess how they got those names. Red and white pulp have different functions. Red pulp contains blood filled sinuses (a fancy name for spaces). The primary function if red pulp is to act as a mechanical filter, removing old red blood cells from general circulation. White pulp contains many B and T type lymphocytes. These cells are vital to the functioning of the immune system. Naturally, this means that the white pulp plays an important role in fighting infections within the body. The spleen is also a secondary manufacturer of red blood cells. In adults most red blood cells are made in the long bones such as your femur, but the spleen is a important producer of red blood cells in a fetus. Once the long bones are fully developed, the spleen's production of red blood cells becomes insignificant.

The immune system is affected if spleen function is lost. The spleen helps your body fight infections. The spleen also makes red blood cells and it removes old red blood cells.

The spleen.
two types of tissue: white pulp and red pulp.
Secondary lymphoid organs and tissues are the sites where lymphocytes are most active. The white pulp of the spleen is the common site for plasma cells to develop. Macrophages are also active in the spleen red pulp; where they engulf blood-borne antigens to be presented to T lymphocytes in the circulation.

The aged red cells self destruct in the spleen , where they squeeze through the red pulp of the spleen. When the spleen is removed, the number of abnormal red cells and old cells circulating in the blood increases considerably.
red pulp is a blood containing region which lie in the spleen, in which open circulation takes place. the open circulation is a pathway taken by the blood in the spleen to flow from the central artery in the white pulp( which will be explained later) through the red pulp and back again to circulatory vessel (vein). blood flow in the open circulation will be exposed to lymphocyte and macro phages in the billroth's cord before it enters splenic sinusoids. this will give better exposure for the blood against any antigen that might present. while the white pulp is the light stained region in the spleen. it consists of central arteries( splenic.a - trabecular.a- central.a), which been sorrounded by periarterial lymphatic sheath( occupied by T lymph). the latter will be sorrounded by lympoid nodules called malphigian corpuscle( occupied by b lymph). between the white and red pulp, there is a marginal zone. this site is the site where highest accumulation of lymphocyte and macrophages. there are also lymphocyte from the red pulp an gather here. it can be said that marginal zone acts as initial immune reaction region.

Pulp is a dietary fiber found in fruits and vegetables. It helps to regulate digestion by adding bulk to stool, promoting regular bowel movements, and aiding in the prevention of constipation. Additionally, pulp can help regulate blood sugar levels by slowing down the absorption of sugars in the body.
