What are the parts of the renal vasculature?

The upper and middle divisions supply the remaining parts of the anterior surface. The other divisions after the segmental arteries are the lobar, interlobar, arcuate, intralobular, and glomerular arteries. The renal artery gives off small branches to the renal capsule and adrenal gland (inferior adrenal artery).

What is the renal vasculature?

The renal arteries are large blood vessels that carry blood from your heart to your kidneys. Renal is another word for kidney. You have two renal arteries. The right renal artery supplies blood to the right kidney, while the left artery sends blood to the left kidney.

How many branches of renal artery are there?

Branches. Before reaching the hilus of the kidney, each artery divides into four or five branches. The anterior branches (the upper, middle, lower and apical segmental arteries) lie between the renal vein and ureter, the vein being in front, the ureter behind.

What is the structure of the renal artery?

The right renal artery originates from the anterolateral aspect of the aorta and runs in an inferior course behind the inferior vena cava to reach the right kidney, while the left renal artery originates slightly higher and from a more lateral aspect of the aorta, and runs almost horizontally to the left kidney.

What is the function of collecting duct?

The collecting duct system funnels urine from the kidney through the ureter to the bladder.

What is nephron and function?

nephron, functional unit of the kidney, the structure that actually produces urine in the process of removing waste and excess substances from the blood. The most advanced nephrons occur in the adult kidneys, or metanephros, of land vertebrates, such as reptiles, birds, and mammals.

What is the renal papilla?

The renal papillae are the areas where the openings of the collecting ducts enter the kidney and where urine flows into the ureters.

What is the first branch of the renal artery?

The renal artery gives off several small branches before dividing into its terminal anterior and posterior branches in the hilum of the kidney….Renal artery.

What is the function of branch of renal vein?

The renal veins are veins that drain the kidney. They connect the kidney to the inferior vena cava. They carry the blood filtered by the kidney.

Where do the renal arteries and veins enter and exit the kidney?

renal hilum
Because the kidney filters blood, its network of blood vessels is an important component of its structure and function. The arteries, veins, and nerves that supply the kidney enter and exit at the renal hilum.

What is the difference between collecting tubule and collecting duct?

The initial collecting tubule is a segment with a constitution similar as the collecting duct, but before the convergence with other tubules. The “cortical collecting ducts” receive filtrate from multiple initial collecting tubules and descend into the renal medulla to form medullary collecting ducts.

What is reabsorbed in collecting duct?

The main role of the collecting duct is the reabsorption of water, through the action of anti-diuretic hormone (ADH) and aquaporins. ADH is produced in the hypothalamus, and stored in the posterior pituitary gland until it is released.

What are the parts of the kidney in anatomy?

Kidney Anatomy. Renal Capsule – outer membrane that surrounds the kidney; it is thin but tough and fibrous. Renal Pelvis – basin-like area that collects urine from the nephrons, it narrows into the upper end of the ureter. Calyx – extension of the renal pelvis; they channel urine from the pyramids to the renal pelvis.

What is the renal artery?

Renal Artery – branches off of the aorta bringing waste-filled blood into the kidney for filtering in the nephrons; the renal artery is further subdivided into several branches inside the kidney. Each minute, the kidneys receive 20% of the blood pumped by the heart. Some arteries nourish the kidney cells themselves.

What are the two components of the renal corpuscle?

The renal corpuscle has two components: the glomerular (Bowman’s) capsule in which sits the glomerulus. The glomerulus is actually a web of arterioles and capillaries, with a special filter which filters the blood that runs through the capillaries, the glomerular membrane.

How are the kidneys drained of venous blood?

The kidneys are drained of venous blood by the left and right renal veins. They leave the renal hilum anteriorly to the renal arteries, and empty directly into the inferior vena cava.
