What organ contains the white pulp?

The spleen is the largest lymphatic organ in the body. Surrounded by a connective tissue capsule, which extends inward to divide the organ into lobules, the spleen consists of two types of tissue called white pulp and red pulp. The white pulp is lymphatic tissue consisting mainly of lymphocytes around arteries.

What is the function of white pulp within the spleen?

The major role of the spleen is to filter blood. The spleen develops and produces mature immune cells that are capable of identifying and destroying pathogens. Contained within the white pulp of the spleen are immune cells called B and T-lymphocytes.

Where are white blood cells found in the spleen?

The white pulp of the spleen contains typical lymphoid elements, such as plasma cells, lymphocytes, and lymphatic nodules, called follicles in the spleen. Germinal centres in the white pulp serve as the sites of lymphocyte production.

the white pulp of the spleen contains lymphocytes which monitor the blood for pathogens, and are capable of initiation an immune response. the rd pulp within the sinusoids of the spleen contains macrophages, which remove foreign substances, pathogens, and either old or defective erythrocytes and platelets.

What does white pulp in the spleen contain?

The white pulp of the spleen contains typical lymphoid elements, such as plasma cells, lymphocytes, and lymphatic nodules, called follicles in the spleen. Germinal centres in the white pulp serve as the sites of lymphocyte production.

When it detects bacteria, viruses, or other germs in your blood, it produces white blood cells, called lymphocytes, to fight off these infections.

Is pancreas and spleen the same?
