Atrial natruiretic hormone
The hormone that counteracts ADH. This hormone induces water, sodium, and potassium loss, decreases blood pressure, and increases glomerular filtration rate. ANH interferes with the renin- angiotensin system by decreasing the release of renin and aldosterone. It also antagonizes the action of vasoconstrictors such as angiotensin II and norepinephrine.

Android obesity
A form of obesity when excess fat stores are found across the shoulders and in the abdominal area. Obesity in which fat is located largely in the waist and abdomen. It is associated with an increased risk of heart disease, hypertension, and diabetes. People with android obesity are often described as having an ’’apple shaped”…

Amylin
Hormone released by the pancreatic ß cells with insulin in response to a glucose signal. It acts in concert with insulin to coordinate the rate of glucose appearance and disappearance in the blood. Amylin is a small peptide having 37 amino acid residues. In healthy adults plasma amylin concentrations range from 4 pmols/L to 25…

Amphipathic
The characteristic of a compound containing both polar and nonpolar groups. This allows the compound to be soluble in both polar and nonpolar solvents. Water is a polar solvent; chloroform is a nonpolar solvent. In chemistry, having polar and nonpolar (water soluble and water-insoluble) regions within a single molecule. This two-part structure allows these chemicals…
