The interlobular arteries give rise to the afferent arterioles of the glomeruli (diminutive form of glomus meaning a ball of blood vessels) that lie within the Bowman’s capsules of the Malpighian corpuscles, and then recombine to produce the efferent arterioles.
What are interlobar vessels?
The interlobar arteries are vessels of the renal circulation which supply the renal lobes. The interlobar arteries branch from the lobar arteries which branch from the segmental arteries, from the renal artery.
Where are the interlobular veins located?
Scheme of renal tubule and its vascular supply. The stellate veins join to form the interlobular veins, which pass inward between the rays, receive branches from the plexuses around the convoluted tubules, and, having arrived at the bases of the renal pyramids, join with the venae rectae.
What do the interlobar arteries pass through?
blood supply ultimately from the interlobar arteries, small vessels that branch off from the main renal arteries; these vessels travel through the cortex of the kidney and terminate in the capsule.
What is the interlobular artery?
Cortical radial arteries, formerly known as interlobular arteries, are renal blood vessels given off at right angles from the side of the arcuate arteries looking toward the cortical substance. … In their outward course, they give off lateral branches, which are the afferent arterioles that supply the renal corpuscles.
What is the difference between Interlobular and interlobar?
The interlobar arteries divide, dichotomously, to originate the arcuate arteries that are located between cortex and medulla, tending to surround one half of a pyramid. … The interlobular arteries give off lateral branches at regular intervals: the afferent arterioles.
Is Interlobular Artery same as cortical radiate artery?

What are the arcuate vessels?
The arcuate vessels of the uterus are a component of the blood supply of the uterus. They are arteries and veins that branch from the uterine arteries and veins, respectively, with additional anastomoses from the ovarian arteries and veins, and penetrate and assume a circumferential course in the myometrium.
What is a Vasa recta?
The vasa recta, the capillary networks that supply blood to the medulla, are highly permeable to solute and water. … Because transport of salt and other solutes requires oxygen and adenosine triphosphate, reduced medullary blood flow decreases salt and solute transport by nephron segments in the medulla.
What is the function of Arcuate vein?
Arcuate Veins: These veins receive oxygen poor blood from the renal cortical veins (3) and drain it into the interlobar veins (6), before it exits via the renal vein (10).

Where is the arcuate artery located?
The arcuate arteries of the kidney, also known as arciform arteries, are vessels of the renal circulation. They are located at the border of the renal cortex and renal medulla.

Where is cortical radiate vein?
The kidneys are bean-shaped organs, 10-12 cm long and 3.5-5 cm thick. They are bilaterally positioned in the upper-posterior abdominal wall with one on either side of the vertebral column.
What arises from the cortical radiate arteries?
The arcuate arteries give off branches that ascend in the cortex called cortical radiate arteries. The afferent arterioles branch off the cortical radiate arteries (a.k.a. interlobular arteries) and bring blood to the glomerulus. Blood drains from the glomerulus by the efferent arteriole.
What is the cortical radiate artery?
the branches of the arcuate arteries of the kidney radiating outward through the renal columns and cortex and supplying the glomeruli.
Which arteries are branches of the segmental arteries quizlet?
Segmental arteries branch into interlobular arteries. Then branch into arcuate arteries. Arcuate arteries branch into interlobular arteries. As interlobular arteries enter the kidney cortex, they extend small branches called afferent arteries.
Is vasa recta peritubular capillaries?
Vasa recta are the special type of peritubular capillaries that feed medulla of the kidney with oxygen and nutrients. They specifically arise from the efferent arteriole of juxtamedullary nephrons and wind around their Henle loops.
Are vasa recta fenestrated?
Terminations of the vasa recta form the straight venules, branches from the plexuses at the apices of the medullary pyramids. … The descending vasa recta have a non-fenestrated endothelium that contains a facilitated transport for urea; the ascending vasa recta have, on the other hand, a fenestrated endothelium.
Is vasa recta present in cortical nephrons?
Vasa recta is well developed in cortical nephrons.

Where are peritubular capillaries located?
Peritubular capillaries are tiny blood vessels in your kidneys. They filter waste from your blood so the waste can leave your body through urine (pee).

What is the first branch of the segmental artery?
The first segmental division is the posterior branch, which exits the main renal artery before it enters the renal hilum. The 4 anterior segmental vessels are, from superior to inferior, the apical, upper, middle, and lower anterior segmental arteries.
What is a segmental artery?
Each segmental medullary artery is a branch of the cervical part of the vertebral artery. These small branches penetrate into the vertebral bone through small openings such as the intervertebral foramina. These segmental arteries provide blood flow to the surface and inside the spinal canal at each segmental level.
What is anterior tibial artery?
The anterior tibial artery is one of the terminal branches of the popliteal artery. It arises below the popliteal fossa, in the posterior (flexor) compartment of the leg. … The artery terminates at the level of the ankle joint, where it gives off its terminal branch, the dorsalis pedis artery.
Is the glomerulus in the medulla or cortex?
The kidney is covered by a connective tissue capsule. The outer part of the kidney is the cortex and the inner part is the medulla. Within the cortex are glomeruli and tubules.
Is the glomerulus a capillary?
The glomerulus, the filtering unit of the kidney, is a specialized bundle of capillaries that are uniquely situated between two resistance vessels (Figure 1). These capillaries are each contained within the Bowman’s capsule and they are the only capillary beds in the body that are not surrounded by interstitial tissue.
What is CBSE 10th glomerulus?
The glomerulus is a network of capillaries, located at the beginning of a nephron in the kidney. The afferent arteriole brings blood to the glomerulus and the efferent arteriole takes blood away from the glomerulus.
