Human Anatomy and Physiology Anatomy - the study of the form or structure and arrangement of body parts and their relationships Physiology - the study of the functions of the body parts or structures and their relationships in maintaining life processes. Levels of Structural Organization The human body consists of levels of structural organization that are associated with one another. There are six levels of structural organization: I. chemical level - It is the simplest level and it includes

Homeostasis Homeostasis is defined as maintaining a constant internal environment. These conditions include water content‚ ion content‚ body temperature and blood glucose concentration. The brain is the centre that monitors and controls the body temperature. The blood glucose concentration is concentrated by the pancreas‚ which produces a hormone known as the insulin; this hormone is able to reduce the blood glucose levels. If there is not enough produced then the disease diabetes is developed.

What can you educate Mr. X to do at home that can help to maintain potassium homeostasis? i). The education Mr. X to maintain potassium homeostasis would consist of the following; do not take medication such as NSAID’S‚ potassium containing salt substitutes‚ angiotensin ii receptor blockers (ARBs)‚ and potassium-sparing diuretics. Do not eat potassium contents

Here we demonstrate the role of apelin (apln) in mammalian aging and identify it as a novel anti-aging factor. We show that apln and its receptor (aplnr) undergo an age-dependent decline in multiple organs. Declining apln levels perturb organismal homeostasis‚ as mice harboring genetic loss of apln (apln-/-) or aplnr (aplnr-/-) exhibit an age-dependent enhancement of their cardiovascular‚ renal‚ metabolic
