The efferent arteriole of a nephron divides to form a network of capillaries known as the peritubular capillaries. These capillaries surround the renal tubules and play a crucial role in reabsorption and secretion processes, facilitating the exchange of substances between the blood and the tubular fluid. In some nephrons, particularly those in the juxtamedullary region, the efferent arteriole also gives rise to the vasa recta, which are important for maintaining the osmotic gradient in the kidney.

Where does the transition from an afferent arteriole to an efferent arteriole occur?

glomerulus. The afferent arteriole leads to a ball of capillaries called a glomerulus which is enclosed in a nephron structure called the glomerular capsule. Blood leaves the glomerulus by way of the efferent arteriole.


Trace the flow of blood through the nephron?

the flow of blood through the nephron is : enters through the afferent arteriole, then flows through the glomerulus and into the efferent arteriole. Blood then enters the peritubular capillaries and the vasa recta and then flows through the cortex and medulla of the kidneys close to the tubules Answer: so the flow is afferent arteriole, efferent arteriole, peritubular capillaries, vasa recta


Does the efferent arteriole take blood to the nephron?

No, the efferent arteriole carries blood away from the glomerulus in the nephron. Blood entering the glomerulus via the afferent arteriole is filtered, and the efferent arteriole carries blood containing the filtered substances away for further processing in the renal tubule.


Cluster of tiny blood vessels in a nephron?

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.


The bowman's capsule contain a podocyte a vasa recta a fenestrated capillarry an efferent arteriole?

The Bowman's capsule is part of the kidney's nephron structure and contains a cluster of capillaries called a glomerulus that is surrounded by podocytes. The efferent arteriole exits the glomerulus, and the vasa recta are responsible for reabsorbing nutrients and water from the kidney tubules. Fenestrated capillaries in the glomerulus allow for efficient filtration of blood.


What is the Function of efferent arterioles?

The afferent arteriole in a nephron is a larger diameter then the outgoing efferent arteriole and this increase the blood pressure in the glomerulus capillaries resulting in the ultrafiltration of the blood into the Bowman's capsule.


Which part of the kidney filters blood?

The nephrons, specifically the glomerulus, are responsible for filtering blood in the kidney. Blood enters the glomerulus through the afferent arteriole and leaves through the efferent arteriole after filtration occurs.


What is the glomerus and in which tissue of the kidney is this part of the nephron located?

The glomerus a capillary tuft which receives its blood supply from an afferent arteriole of the renal circulation. Its blood pressure provides the power to force fluids and solutes to be filtered out of the blood into the space made by the Bowman's capsule. The remaining unfiltered blood passes into the narrower efferent arteriole. It then moves into the vasa recta, the collecting capillaries intertwined with the convoluted tubules through the interstitial space where the reabsorbed substances also enter. It then joins with the efferent venules of the other nephrons into the renal vein before rejoining with the main bloodstream.


What are the parts of a nephron?

The parts of the nephron are the renal artery, renal vein, afferent arteriole, glomerulus, bowman's capsule, proximal tubules, distal tubules, loop of henle, renal pelvis, cortex, medulla, peritubular capillaries, and ureter.


The blood vessels that exchange substances with the nephron?

The afferent arteriole.


The portion of the nephron receiving filtrate from the glomerular capsule?

The portion of the nephron receiving filtrate from the glomerular capsule is the proximal convoluted tubule. It is responsible for reabsorbing substances such as glucose, ions, and water from the filtrate into the blood. This process helps regulate the body's balance of electrolytes and fluid volume.


Which group of capillaries found in a nephron?

The glomerulus
