What are the two types of meristematic tissues?
. 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.
What does the spleen do with red blood cells?
Red pulp is involved as a reservoir for formed elements of the blood. Source: I'm Awesome
What is the function of a spleen in a perch?
production of red blood cells and immune response
What are the two organs that produce red blood cells prior to birth?
The two organs that produce red blood cells prior to birth are the liver and the spleen. After birth, the bone marrow takes over as the primary site of red blood cell production.
What organ is bean shaped and responsible for Red Blood Cell storage when it comes to frogs?
The spleen is the bean-shaped organ found in frogs that is responsible for storing red blood cells. It also plays a role in immune function by filtering the blood and removing old or damaged red blood cells.
Which part of the spleen is involved in the storage of monocytes?

Filters blood and contain red and white pulp?
The spleen.
What are secondary organics?
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.
What is the Difference between white pulp and red pulp?
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.
What is secondary lymphoid tissue?
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 white pulp of the spleen is composed primarily of?
The white pulp of the spleen is primarily composed of lymphocytes, which are a type of white blood cell involved in the immune response. This area of the spleen is responsible for filtering the blood and detecting and responding to foreign invaders, such as bacteria and viruses.
Does the spleen contain erythrocytes?
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.
What does pulp do in your body?
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.
Why is the spleen part of the immune system?
The spleen is a purplish red organ located in the upper left part of your abdominal cavity. The spleen is an integral part of the immune system. The spleen filters blood, removes old or damaged platelets and red blood cells, stores blood, and forms some types of white blood cells. If the spleen is damaged it can be removed. You can live without your spleen, but your resistance to infection will be lowered.
How does the spleen protect you from disease?
The spleen is a gland that works closely with the circulatory system. The spleen produces, monitors, destroys and stores red blood cells. The spleen also has two other functions, the red and white pulp. The white pulp helps fight infections and the red pulp removes unwanted materials. Until recently, the purpose of the spleen was not known. The spleen is above the stomach to the left, underneath the rib cage. Spleens in healthy adults are 9 to 13 centimetres (3.5 to 5.1 in) in length.
