LO1:Describe the cellular composition of the spleen and identify its key functional components
A Coggle Diagram about The splenic artery delivers blood to the spleen where it is filtered by the red pulp. The red pulp is made up of cords of connective tissue and wide blood vessels called splenic sinusoids. Blood passes through the cords and into the sinusoids where it is drained into the large trabecular veins of the spleen,
, ( ( ( (T cells help to recognise bacteria and viruses that might cause illness and then destroy them. While B-cells produce antibodies that can coat the pathogen to make them easier to remove.RK
)), Red pulp is the site of blood filtration in the spleen. It is made of connective tissue called the cord of Billroth' or splenic cords and venous sinuses. Splenic cords consist of red blood cells, macrophages, lymphocytes, plasma cells and granulocytes. Rk
, White pulp is lymphatic tissue mainly made up of lymphocytes and macrophages arranged around branches of the splenic artery known as central arteries. RK
and ) and Large trabeculae originate at the hilum, on the medial surface of the spleen; these trabeculae carry nerves, arteries and veins.RK
() and (Within the red pulp, the spleen carries out three main functions associated to blood cells:• It removes worn out red blood cells or defective blood cells and platelets
• It stores up to one third of the body’s supply of platelets.
• Red pulp can also act like bone marrow in unborn babies (foetuses), producing new blood cells. RK
)) and *
(A Blood flow into the spleen through the splenic artery enters the white pulp. Within the white pulp, B cells and T cells carry out immune functions. RK
)), (The spleen is made up of two basic types of tissue, each with different functions: 1) white pulp. 2) red pulp
), The red pulp filters the blood, removing unwanted material. The red pulp contains other white blood cells called phagocytes that ingest microorganisms, such as bacteria,fungi and viruses, It also monitors red blood cells, destroying those that are abnormal or too old or damages to function properly.
, The spleen is a soft organ surrounded by a thin elastic capsule of dense connective tissue. The spleen is almost completely covered by visceral peritoneum except the hilum where the vessels and nerves pass through. RK
, It is similar in structure to a lymph node and spleen also has a hilum, like lymph nodes. Spleen is an important organ that helps keep your body’s fluid levels in the balance. It is found on the left side of the abdomen, under the ribs.RK
, The inner part of capsule carries the blood vessels and extends into the pulp. Inward extensions of the capsule are known as the trabeculae, which divide the parenchyma or splenic pulp into incomplete compartments. RK
, The spleen is an organ found in virtually all vertebrates. similar in structure to a large lymph node, it acts primarily as a blood filter and to fight infection.
, The parenchyma consists of two types of tissues: red pulp and white pulp. RK
, The white pulp is part of the immune system: it produces white blood cells called lymphocytes, which in turn produce antibodies.
and It is the largest single mass of lymphatic organ in the body, measuring about 12 cm in length and weights between 150 and 200 grams in healthy adult. RK
