What is the correct order in renal blood flow?
The renal artery first divides into segmental arteries, followed by further branching to form multiple interlobar arteries that pass through the renal columns to reach the cortex. The interlobar arteries, in turn, branch into arcuate arteries, cortical radiate arteries, and then into afferent arterioles.
Which is the correct order of blood flow in the kidneys after the efferent arterioles?
The correct answer is (b) Afferent arterioles, glomerulus, efferent arteriole, peritubular capillaries.
Where does blood flow after the efferent arteriole?
Afferent arterioles branch off which ultimately leads into the glomerulus of Bowman’s capsule. From here, efferent arterioles begin to form the venous system and subdivide into another set of capillaries known as the peritubular capillaries. Blood then leaves the kidney and enters the venous circulation.
Which of the following is the correct sequence of blood flow through the kidneys on its route to the glomeruli of the nephrons?
Which of the following represent the correct sequence of blood flow through the nephron? Blood enters the kidney through the renal artery – afferent arteriole – glomerulus – efferent arteriole – peritubular capillaries – renal vein – exits the kidney.
What happens when the efferent arteriole dilates?
Increased blood volume and increased blood pressure will increase GFR. Constriction in the afferent arterioles going into the glomerulus and dilation of the efferent arterioles coming out of the glomerulus will decrease GFR. Hydrostatic pressure in the Bowman’s capsule will work to decrease GFR.
What is the difference between afferent arteriole and efferent Arteriole?
Afferent arteriole is a branch of the renal artery that brings in blood to the glomerulus. Efferent arteriole is a branch of the renal artery that drains blood away from the glomerulus.
Which is the correct order of blood flow?
Blood flows through the heart in the following order: 1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) …
What is the function of the afferent and efferent arterioles?
Afferent and efferent arterioles are responsible for the supply of blood to the glomerulus of the kidney. The glomerulus is a branch of blood capillaries. It functions by receiving the blood through an afferent arteriole and the blood comes out through the efferent arteriole.
What is the function of the efferent Arteriole?
The efferent arterioles form a convergence of the capillaries of the glomerulus, and carry blood away from the glomerulus that has already been filtered. They play an important role in maintaining the glomerular filtration rate despite fluctuations in blood pressure.
Which of the following is not in the sequence of proper kidney blood flow?
A&P 2 urinary

What is the function of afferent arteriole and efferent arteriole?
Afferent arteriole is a branch of the renal artery that brings in blood to the glomerulus. Efferent arteriole is a branch of the renal artery that drains blood away from the glomerulus. Afferent arteriole carries blood to the glomerulus. Efferent arteriole takes blood away from the glomerulus.
How does afferent Arteriolar constriction affect renal blood flow?
Effect of afferent arteriolar and efferent arteriolar constriction and dilation on renal blood flow (RBF), glomerular filtration rate (GFR), and filtration fraction (FF). Constricting the afferent arteriole reduces RBF because the vascular resistance is increased.
What are the effects of afferent and efferent arterioles?
Thus constriction of the afferent and efferent arterioles exerts separate effects on RBF and the GFR, as detailed in Figure 7.6.1. Figure 7.6.1. Effect of afferent arteriolar and efferent arteriolar constriction and dilation on renal blood flow (RBF), glomerular filtration rate (GFR), and filtration fraction (FF).
How does dilation of the afferent arterioles affect RBF?
Dilation of the afferent arterioles has the opposite effects. Constriction of the efferent arterioles also increases the vascular resistance so it reduces RBF. The pressure within the glomerular capillaries may increase, however, because the flow is slowed by efferent arteriolar constriction.
How are afferent arterioles related to glomerular filtration equilibrium?
However, the slower blood flow means that glomerular filtration has more time to approach filtration equilibrium, so constriction of the afferent arterioles ought to raise slightly the filtration fraction (=GFR/RBF). Dilation of the afferent arterioles has the opposite effects.
