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.
Overview. The lymphatic system has the responsibility of keeping you alive and healthy. The spleen, which is in the upper left abdominal area, is one of the organs in this system. The spleen of an adult holds the largest amount of lymphoid tissue. An adult spleen is about 5 inches long and weighs approximately 4 oz.
The spleen is a lymphoid organ located in the abdomen. It's functions may be broadly separated into two groups. 1. Culling and removal of old or senescent red blood cells once they are near the end of their life span. 2. Immune function - synthesis of antibodies and other components of the immune system such as opsonins.
