6 FAQs about [The spleen can store blood]
Does the spleen store red blood cells?
In some animals (such as horses and dogs), the spleen can store a significant amount of red blood cells. While this function is less pronounced in humans, the spleen does hold a small reserve of red blood cells that can be released into the bloodstream in response to situations such as hypoxia (low oxygen levels).
Where is the spleen located in the body?
The spleen is located behind ribs 9 through 11 in the upper left of the abdomen, protected by the rib cage. It is the largest organ of the lymphatic system — the circulatory component of the immune system. It recycles iron, destroys old red blood cells, and stores white blood cells and platelets, the components of the blood that help stop bleeding.
Can red blood cells pass through the spleen?
When the red blood cells’ size, shape, or ability to deform is altered, they can’t pass through. Under certain conditions, such as hereditary spherocytosis, misshapen red blood cells can get trapped in the spleen, leading to anemia.
How does the spleen affect blood clots?
It affects the number of red blood cells that carry oxygen throughout your body, and the number of platelets, which are cells that help your blood to clot. It does this by breaking down and removing cells that are abnormal, old, or damaged. The spleen also stores red blood cells, platelets, and infection-fighting white blood cells.
How does the spleen filter blood?
The spleen filters the blood, removing old or unwanted cells and platelets. As blood flows into the spleen, it detects any red blood cells that are old or damaged. Blood flows through a maze of passages in the spleen. Healthy cells flow straight through, but those considered unhealthy are broken down by large white blood cells called macrophages.
How does the spleen store iron?
The spleen stores iron temporarily before it is transported to the liver and bone marrow via transferrin, a blood protein responsible for iron transport. This process ensures a constant supply of iron for hematopoiesis, the production of new red blood cells.
