The efferent arterioles are blood vessels that are part of the urinary tract of organisms. Efferent (from Latin ex + ferre) means "outgoing", in this case meaning carrying blood out away from the glomerulus.
The afferent arterioles are a group of blood vessels that supply the nephrons in many excretory systems. They play an important role in the regulation of blood pressure as a part of the tubuloglomerular feedback mechanism. The afferent arterioles branch from the renal artery, which supplies blood to the kidneys.
An arteriole is a small-diameter blood vessel in the microcirculation that extends and branches out from an artery and leads to capillaries. [1] Arterioles have muscular walls (usually only one to two layers of smooth muscle cells) and are the primary site of vascular resistance.
Central to the physiologic maintenance of GFR is the differential basal tone of the afferent (input) and efferent (output) arterioles (see diagram). In other words, the filtration rate is dependent on the difference between the higher blood pressure created by vasoconstriction of the afferent arteriole versus the lower blood pressure created by ...
Efferent arterioles take blood out of your glomerulus. Arterioles in your lungs constrict or tighten when there’s not enough oxygen. This moves blood away from areas in your lungs without enough oxygen and toward areas of your lungs with more oxygen.
23 lis 2017 · An efferent arteriole is a branch of the renal artery, which carries filtered blood back to the circulation. The blood pressure of the afferent arteriole is high, facilitating the ultra-filtration of blood plasma at the glomerulus.
21 lis 2023 · The afferent arteriole (A before E) delivers blood to the kidney, and the efferent arteriole (E after A) takes blood away from the kidney. The letter E can also stand for exception.
