What is the function of the 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).

What is an arcuate vein?

Medical Definition of arcuate vein : any of the veins of the kidney that accompany the arcuate arteries, drain blood from the interlobular veins, and empty into the interlobar veins.

What does the arcuate artery supply?

The arcuate artery of the foot is a branch of the dorsalis pedis artery. It courses on the dorsum of the foot, passing laterally over the bases of the metatarsal bones beneath the tendons of the extensor digitorum brevis muscle. … Arcuate artery of the foot.

Origin Dorsalis pedis artery
Supply Toes II, III and IV and interdigital clefts

Where are the arcuate arteries and veins 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. They are named after the fact that they are shaped in arcs due to the nature of the shape of the renal medulla.

What is the arcuate artery and vein?

The arcuate vein is a vessel of the renal circulation. It is located at the border of the renal cortex and renal medulla. …

Where does arcuate artery come from?

The arcuate artery of the foot (metatarsal artery) arises from dorsalis pedis slightly anterior to the lateral tarsal artery, specifically over the naviculocuneiform joint; it passes lateralward, over the bases of the lateral four metatarsal bones, beneath the tendons of the extensor digitorum brevis, its direction …

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 do interlobar veins unite?

The sublobular veins unite to form larger and larger trunks, and end at last in the hepatic veins, these converge to form three large trunks which open into the inferior vena cava while that vessel is situated in its fossa on the posterior surface of the liver.

Where are peritubular capillaries located?

Peritubular capillaries surround the cortical parts of the proximal and distal tubules, while the vasa recta go into the medulla to approach the loop of Henle.

What is a nephron?

Each of your kidneys is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus, and a tubule. … Each nephron has a glomerulus to filter your blood and a tubule that returns needed substances to your blood and pulls out additional wastes.

What does the renal vein carry?

The main blood vessel that carries blood from the kidney and ureter to the inferior vena cava (a large vein that carries blood to the heart from the lower part of the body). There is a renal vein for each kidney.

What is plantar artery?

n. An artery that is the larger of two branches of the posterior tibial artery, forms the plantar arch and supplies the sole and the plantar surfaces of the toes; with anastomoses to the medial plantar artery and the dorsal artery of the foot; lateral plantar artery.

Does the arcuate artery carry blood into the kidney?

The interlobar arteries then supply blood to the arcuate arteries that run through the boundary of the cortex and the medulla. Each arcuate artery supplies several interlobular arteries that feed into the afferent arterioles that supply the glomeruli. …

Anatomical terminology

Are arcuate arteries end arteries?

The arcuate arteries converge near the centers of the basal surfaces of the pyramids, but do not anastomose (end arteries). The arcuates give off branches: the interlobular or cortical radial arteries, which are arranged radially over the basal surface of the pyramids, perpendicular to the renal surface.

What is the afferent arteriole?

The afferent arteriole is an arteriole that feeds blood into the glomerulus. … The afferent arterioles modulate their vascular resistance in response to changes in intraluminal pressure or composition of tubular fluid at the macula densa. In this manner, they control the glomerular filtration.

What is the function of interlobar artery?

Each interlobar artery branches over the base of the pyramid. Smaller arteries and capillaries divide off from the interlobar arteries to supply each pyramid and the cortex with a rich network of blood vessels. Blockage of an interlobar artery can cause degeneration of a renal pyramid.

Which blood vessel conveys blood out of the nephron?

Renal Vein: Renal vein takes blood away from the kidney. The process starts with the renal artery which enters the kidney as afferent arteriole.

What capillary bed produces filtrate?

Which capillary bed produces filtrate? A (glomerulus. The glomerulosa (capillary bed) in the glomerular capsule produces filtrate due to the high fluid pressure within the vessels.)

Which blood vessel comes next in this sequence interlobar artery arcuate artery Interlobular artery?

The interlobar arteries, in turn, branch into arcuate arteries, cortical radiate arteries, and then into afferent arterioles.

What are Vasa recta?

The vasa recta of the kidney, (vasa rectae renis) are the straight arterioles, and the straight venules of the kidney, – a series of blood vessels in the blood supply of the kidney that enter the medulla as the straight arterioles, and leave the medulla to ascend to the cortex as the straight venules.

Where is the renal medulla?

the kidney renal medulla: The inner-most region of the kidney, arranged into pyramid-like structures, that consists of the bulk of nephron structure. renal cortex: The outer region of the kidney, between the renal capsule and the renal medulla, that consists of a space that contains blood vessels that connect to the nephrons.

Are hepatic veins Interlobar?

The portal venous, hepatic arterial and biliary systems run to- gether within the intrasegmental parts of the hepatic parenchyma, but the main hepatic veins course in the interlobar or intersegmental fissures of the liver.

Why do kidneys have two tuft of capillaries?

The blood is filtered across the capillary walls of this tuft through the glomerular filtration barrier, which yields its filtrate of water and soluble substances to a cup-like sac known as Bowman’s capsule. … Glomerulus (kidney)

Glomerulus
Precursor Metanephric blastema
Location Nephron of kidney

Where does blood go after the peritubular capillaries?

Blood leaves the peritubular capillaries, collects in progressively larger venules and veins, and then exits the kidney via the renal vein. Filtrate formed in Bowman’s capsule remains separated from the body fluid spaces by a layer of epithelial cells that extends through the remainder of the urinary system.

What is the function of the peritubular capillaries and Vasa recta?

Function. Furthermore, vasa recta serve as osmotic exchangers for the concentration of urine, while peritubular capillaries supply the blood for reabsorption and secretion.
