Endocrine System Essay

The endocrine system is composed by a group of glands that secrete hormones for the secretion of a specific organ and the result of this cycle will contribute to of physiological and behavioral activities. The circulatory system makes a connection with the hormones secreted because it helps them to travel around the human body in a very short time. The endocrine glands that secrete the hormones that target specific hormones consist of the pituitary gland, thyroid gland, adrenal gland, pancreas, ovaries and testes. However, they are secondary organs part of the body system such as the kidney, liver, and heart. The kidney in particular secretes endocrine hormones such as renin and erythropoietin (EPO). Erythropoietin is a hormone that controls

There are different types of anemia that affect millions of Americans, the leading problems in the bone marrow and stem problems. Anemia results in cell problems as aplastic anemia, in which the reduction of or absence of stem cells are too low. The characteristics of the unusual capacity of self renewal inhibit the capacity of regeneration in the bone marrow leading to Aplastic Anemia (AA). The mature stem cells are the functional supply over the life time that protect the physiological needs of the human body. The response of aplastic anemia is the blood loss or hypoxia in response of multiple infections that may target the immune system during advanced stages. As Polycithemia the treatments for aplastic anemia are radiation, medication and chemotherapy in order to stimulate stem cell

Leukemia is a type of cancer that that grows out of control inside of the spongy parts of the bone, although this type of cancer is mainly introduced by the exposition of the body to larger amount of radiation, lead by a previous cancer the body or by a gene mutation (abnormal chromosomes) cause by heredity in the family history. Treatment for this type of cancer in the bones is to destroy the leukemia cells to allow the healthy cells to stimulate the correct proportion of normal stem cells in the red bone marrow. Induction therapy is used for primarily stages of leukemia which consist of radiation and chemotherapy in order to kill the degenerative cells inside the bone marrow, but it is important to mention that this type of treatment kills all types of cells and cause secondary health problems. Consolidation therapy consist of a red bone marrow transplantation, this type of treatment include the induction of the medulla of a close relative to increase the red blood cell production in the diagnosed person with
