What is the juxtaglomerular apparatus in the body?
The juxtaglomerular apparatus is a microscopic structure in the kidney, which regulates the function of each nephron. The juxtaglomerular apparatus is named for its proximity to the glomerulus: it is found between the vascular pole of the renal corpuscle and the returning thick ascending limb of the same nephron. This location is critical to its function in regulating renal blood flow and glomerular filtration rate. The three cellular components of the apparatus are the macula densa, extraglomerular mesangial cells, and juxtaglomerular cells
How does renin-angiotensin negative feedback loop helps regulate blood pressure and glomerular filtration rate in response to dehydration?
Dehydration causes a decrease in blood volume and pressure, which decreases GFR. The JG cells of the juxtaglomerular apparatus sense decreased stretch and macula densa cells sense decreased water. The JG cells secrete renin which converts angiotensinogen in blood to angiotensin I. The latter is converted to angiotensin II by ACE in the lungs. Angiotensin II causes constriction of efferent arterioles, increased thirst, greater ADH secretion from the posterior pituitary and increased secretion of aldosterone from the adrenal corted. Blood volume is increased, which increases venous return, stroke volume, cardiac output, and BP
The kidneys regulate the chemical composition of blood by utilizing the process of?
Filtration and Absorption
What do the baroreceptors regulate?
They regulate blood pressure.
What do kidney regulate in the blood?
They help regulate blood pressure (I think)
How the kidney maintain the body's internal environment?
It helps to regulate blood pressure through the renin-angiotensin system. Kidneys are also responsible for filtration, excretion, retention, and secretion of wastes (urea, nitrogen, excess ions, and toxins).
