What is the role of afferent and efferent arteriole on glomerular filtration?

What is the role of afferent and efferent arteriole on glomerular filtration?

Afferent arteriole gives only oxygenatedblood which is loaded with waste marterials. But efferent arteriolr send deoxygenated blood to renal vien .

What does efferent arteriole give rise to?

After passing through the renal corpuscle, the capillaries form a second arteriole, the efferent arteriole. These efferent arterioles will feed the next capillary networks around the more distal portions of the nephron tubule, the peritubular capillaries and vasa recta, before returning to the venous system.

Where does the efferent arteriole take blood to?

The afferent arteriole (A before E) delivers blood to the kidney, and the efferent arteriole (E after A) takes blood away from the kidney.

What is the function of the macula densa cells of the Juxtaglomerular Complex JGC )?

What is the function of the macula densa cells of the juxtaglomerular complex (JGC)? The macula densa cells monitor the NaCl content of the filtrate entering the distal convoluted tubule.

What is the function of peritubular capillaries?

In the renal system, peritubular capillaries are tiny blood vessels, supplied by the efferent arteriole, that travel alongside nephrons allowing reabsorption and secretion between blood and the inner lumen of the nephron.

Which blood vessel the afferent arteriole of the efferent arteriole has the larger diameter quizlet?

The afferent arteriole is the arteriole that brings blood to the glomerulus. It is larger in diameter than the efferent arteriole. The efferent arteriole is the arteriole that carries blood away from the glomerulus. It is smaller in diameter than the afferent arteriole.

Why is it important for the efferent arteriole to be smaller in diameter than the afferent arteriole?

The efferent arteriole carries blood away from the glomerulus. Because it has a smaller diameter than the afferent arteriole, it creates some resistance to blood flow, producing the back-up of blood in the glomerulus which creates higher pressure in the glomerular cavity.

What happens to the efferent arteriole after it leaves the glomerulus?

The efferent arterioles of the undifferentiated cortical glomeruli are the most complex. Promptly on leaving the glomerulus they break up into capillaries and become part of a rich plexus of vessels surrounding the cortical portions of the renal tubules.

What is the difference between afferent and efferent arteries?

The main difference between afferent and efferent arterioles is that afferent arterioles carry blood to the glomerulus whereas efferent arterioles take the blood away from the glomerulus. An afferent arteriole is a branch of the renal vein, which carries blood containing nitrogenous wastes.

What is the main function of the arterioles?

The function of the arterioles, therefore, is to regulate blood pressure so that it remains steady and less prone to fluctuation. By doing so, the blood will no longer be pulsing as it reaches the capillaries.

How do efferent and afferent neurons differ?

Afferent neurons are also known as sensory neurons while efferent neurons are called as motor neurons. Afferent neurons begins with a receptor efferent ends with effector. Efferent neurons has short dendrite and long axon while afferent has long dendrite and short axon .

What is the definition of efferent?

Definition of efferent. : conducting outward from a part or organ specifically : conveying nervous impulses to an effector efferent neurons — compare afferent .
