Wisdom teeth, or third molars, may come into the mouth as early as 16 years of age but usually they come in several years later. This question is prompted by hearing stories about wisdom tooth problems. These problems are often due to inadequate space in the back of the mouth for these teeth to grow in.
The spleen plays important roles in regard to red blood cells (also referred to as erythrocytes) and the immune system. It removes old red blood cells and holds a reserve of blood, which can be valuable in case of hemorrhagic shock, and also recycles iron. In humans, up to a cup (236.5 ml) of red blood cells can be held in the spleen and released in cases of hypovolemia. 2  It can store platelets in case of an emergency and also clears old platelets from the circulation.
What is spleen cancer? The spleen is an organ located under the ribs on the left side of the body. It is part of the lymphatic system, which is composed of lymph nodes, lymph vessels, lymphatic fluid, the tonsils, thymus, spleen, and lymphoid tissue of the digestive tract. The spleen filters the blood and helps the body fight infections. Most splenic cancers do not start in the spleen, and those that do are almost always lymphomas. Lymphoma is a type of blood cancer that develops in the lymphatic system.
