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.
Introduction. The spleen is a fist-sized organ found in the upper left side of your abdomen, behind your stomach and left ribs. Some people are born without a spleen or need to have it removed because of disease or injury.he spleen has a few important functions: 1  it fights any invading germs in the blood (the spleen contains infection-fighting white blood cells). 2  it controls the level of white blood cells, red blood cells and platelets (platelets are small cells that form blood clots).
