The afferent arterioles
Juxtaglomerular apparatus
The vascular structure found between the afferent and efferent arterioles in the kidney is the glomerulus, where filtration of blood takes place.
afferent glomerular arteriole a branch of an interlobular artery that goes to a renal glomerulus.efferent glomerular arteriole one arising from a renal glomerulus, breaking up into capillaries to supply renal tubules.Remember because they are arterioles NOT venules they they both carry blood away from the heart.
Glomerulus capillary
Blood leaves the glomerular capillaries via a second set of arterioles, the efferent arterioles, which deliver blood to the peritubular capillaries.
Lot of fluid is filtered out in the glomeruli. Almost 180 litres of fluid per day is filtered in glomeruli. So to maintain the blood pressure in afferent arterioles, you need to have efferent arterioles with less diameter.
In the majority of the body all arterioles are afferent as they take blood to the organs they supply. however the tru afferent arterioles are only found in the functional unit of the kidney called the nephron. At the very start of the nephron is a bundle of cappillaries that allows diffusion of the majority of the plasma and contents to diffuse out into another structure called the bormans capsule. From the bowmans capsule the liquid travels through the nephron and any substances that the body still wants to keep diffuse back into the blood. The arteriole that carries blood to the glomerulus is the afferent arteriole and the arteriole that recollects the usefull parts comes from the glomerulus and so is called the efferent arteriole.
There's the afferent arteriole which goes to the glomerulus and the efferent arterioles which comes out of the glomerulus. These arterioles then branch out surrounding the nephron, these are called peritubular capillaries and they allow for selective reabsorption of substances as well as secretion.
Sympathetic stimulation causes vasoconstriction of the afferent arterioles in the kidneys. This response reduces blood flow into the glomeruli, which can decrease glomerular filtration rate (GFR). The effect is part of the body's mechanism to prioritize blood flow to vital organs during stress or low blood volume situations. Ultimately, this helps conserve water and maintain blood pressure.
High osmolarity or high Na+ and Cl- in the ascending loop of Henle will cause afferent arterioles to constrict by releasing adenosine. This response helps to reduce glomerular filtration rate to maintain a balance in the kidney's filtration processes.
Efferent means going away from and afferent is going toward. The afferent arteriole of the kidney carrys blood toward the glomerulus, whereas the efferent arteriole carrys blood away from the glomerulus.
