BCAA consists of the amino acids leucine, isoleucine and valine. The reason these three amino acids are called BCAA is because they branch off from the other five essential amino acids, (there are a total of eight), to create their own chain. Amino acids are responsible for the formation of proteins in the body.
An aneurysm is an abnormal bulging out or ballooning of a portion of the artery, usually due to weakness of the arterial wall. The aneurysm may enlarge and rupture, often with disastrous consequences.
An arteriole is the branching off of an artery. Now that we have reviewed blood flow, it's time to define what an efferent arteriole is and review its function in the blood flow process. An efferent arteriole is an arteriole that delivers blood away from the capillaries of the kidney.
