The protein angiotensinogen is produced and secreted by
Hepatocytes
JG cells
Macula densa cells
Endothelial cells of blood vessels
Answers
Answer:
Angiotensinogen is a αα - globulin protein produced by liver cells. Renin changes angiotensinogen to angiotensin II (hormone) in response to fall in glomerular blood flow/glomerular blood pressure/GFR. Angiotensin II increases blood pressure and blood volume
The macula densa is a collection of specialized epithelial cells in the distal convoluted tubule that detect sodium concentration of the fluid in the tubule. ... The juxtaglomerular cells, derived from smooth muscle cells, of the afferent arteriole secrete renin when blood pressure in the arteriole falls.
Endothelium is a single layer of squamous endothelial cells that line the interior surface of blood vessels, and lymphatic vessels. ... Endothelial cells form the barrier between vessels and tissue and control the flow of substances and fluid into and out of a tissue.
