The Holocene /ËhÉlÉµsiËn/ is the geological epoch that began after the Pleistocene at approximately 11,700 years BP and continues to the present. The Holocene is part of the Quaternary period. Its name comes from the Greek words á½Î»Î¿Ï (holos, whole or entire) and ÎºÎ±Î¹Î½ÏÏ (kainos, new), meaning entirely recent. It has been identified with the current warm period, known as MIS 1, and can be considered an interglacial in the current ice age based on that evidence.
Removal of Red Blood Cells. One of the functions of the spleen is to remove any old red blood cells, according to Kim Barrett, professor of medicine at the University of California at San Diego, writing in âGanongâs Review of Medical Physiology.â The normal lifespan of a red blood cell is 120 days.
What is the spleen? The spleen is an abdominal organ located near the stomach. The spleen contains two types of tissue, red pulp and white pulp. The main function of the spleen (red pulp) is to filter the blood, removing worn out blood cells and recycling the proteins and iron. It is also a reserve factory for manufacture of blood cells.
