[Answer] What major role do the kidneys play in the cardiovascular system?

Answer: Regulate blood pressure by altering blood volume
What major role do the kidneys play in the cardiovascular system?

The kidneys are two reddish-brown bean-shaped organs found in vertebrates. They are located on the left and right in the retroperitoneal space and in adult humans are about 12 centimetres (4 ⁄2 inches) in length. They receive blood from the paired renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter a tube that carries excreted urine to the bladder. The nephronis the structural and functional unit of the kidney. Each adult human kidney contains aroun…

The kidney participates in whole-body homeostasis regulating acid-base balance electrolyte concentrations extracellular fluid volume and blood pressure. The kidney …

Wed Jul 16 2003 14:30:00 GMT-0400 (Eastern Daylight Time) · The renin–angiotensin system or renin–angiotensin–aldosterone system is a hormone system that regulates blood pressure and fluid and electrolyte balance as well as systemic vascular resistance. When renal blood flow is reduced juxtaglomerular cells in the kidneys convert the precursor prorenin into renin and secrete it directly into circulation. Plasma renin then carries out the …

The essential components of the human cardiovascular system are the heart blood and blood vessels. It includes the pulmonary circulation a “loop” through the lungs where blood is oxygenated; and the systemic circulation a “loop” through the rest of the body to provide oxygenated blood. The systemic circulation can also be seen to function in two parts – a macrocirculation and a microcirculation. An average adult contains five to six quarts (roughly 4.7 to 5.7 liters) of blood accounting for approximately 7% of their to…

Regulation of renal blood flow is important to maintaining a stable glomer ular filtration rate (GFR) despite changes in systemic blood pressure (within about 80-180 mmHg). In a mechanism called tubuloglomerular feedback the kidney changes its own blood …

The autonomic nervous system plays a central role in maintaining cardiovascular homeostasis via pressure volume and chemoreceptor…
