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 plays multiple supporting roles in the body. It acts as a filter for blood as part of the immune system. Old red blood cells are recycled in the spleen, and platelets and white blood cells are stored there.The spleen also helps fight certain kinds of bacteria that cause pneumonia and meningitis.ront View of the Spleen.
