The blood pressure of the afferent arterioles is high. And the diameter of the afferent arterioles is changing according to the varying blood pressure of human body. Figure 01: The Afferent and Efferent Arterioles The afferent arterioles are a group of blood vessels that supply the nephrons in many excretory systems.

WebThe two arterioles change in size to increase or decrease blood pressure in the glomerulus. In addition, efferent arterioles are smaller in diameter than afferent arterioles. As a result, pressurized blood enters the glomerulus through a relatively wide tube, but is forced … Webafferent arteriole: (1) Afferent glomerular arteriole, arteriola glomerularis afferens. (2) Any arteriole that connects the terminal branch of an artery with a capillary.

WebThe myogenic mechanism regulating blood flow within the kidney depends upon a characteristic shared by most smooth muscle cells of the body. When you stretch a smooth muscle cell, it contracts; when you stop, it relaxes, restoring its resting length. This mechanism works in the afferent arteriole that supplies the glomerulus.

WebAt the point where the afferent arterioles enter the glomerulus and the efferent arteriole leaves it, the tubule of the nephron touches the arterioles of the glomerulus from which it arose. At this location, in the wall of the distal convoluted tubule, there is a modified region of tubular epithelium called the macula densa. [2] WebNephrin is a zipper -like protein that forms the slit diaphragm, with spaces between the teeth of the zipper big enough to allow sugar and water through but too small to allow proteins through. Nephrin defects are responsible for congenital kidney failure. CD2AP regulates the podocyte cytoskeleton and stabilizes the slit diaphragm. [3] [4]
