what are renal blood vessels?

Renal Veins carry filtered blood from the kidneys to the posterior vena cava. Renal Arteries carry unfiltered blood from the aorta to the kidneys. The arteries are obscured by the renal veins in this image; they are dorsal to the renal veins.

Renal capsule, thin membranous sheath that covers the outer surface of each kidney. The capsule is composed of tough fibres, chiefly collagen and elastin (fibrous proteins), that help to support the kidney mass and protect the vital tissue from injury.

Juxtaglomerular Apparatus. The juxtaglomerular apparatus is a specialized structure formed by the distal convoluted tubule and the glomerular afferent arteriole. ... The juxtaglomerular cells, derived from smooth muscle cells, of the afferent arteriole secrete renin when blood pressure in the arteriole falls.

Over time, high blood pressure harms renal blood vessels The nephrons in the kidneys are supplied with a dense network of blood vessels, and high volumes of blood flow through them. Over time, uncontrolled high blood pressure can cause arteries around the kidneys to narrow, weaken or harden.

The Three Major Types of Blood Vessels: Arteries, Veins, and Capillaries.

Over time, uncontrolled high blood pressure can cause arteries around the kidneys to narrow, weaken or harden. These damaged arteries are not able to deliver enough blood to the kidney tissue. Damaged kidney arteries do not filter blood well. Kidneys have small, finger-like nephrons that filter your blood.

Renal artery disease: A blockage in the renal arteries can cause renal artery disease (stenosis). The symptoms include uncontrolled hypertension (high blood pressure), congestive heart failure, and abnormal kidney function.

They are located just below the rib cage, one on each side of your spine. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine. The urine flows from the kidneys to the bladder through two thin tubes of muscle called ureters, one on each side of your bladder.

Blood vessels are found throughout the body. There are five main types of blood vessels: arteries, arterioles, capillaries, venules and veins. Arteries carry blood away from the heart to other organs. They can vary in size.

Renal artery carries mineral rich, oxygenated blood from the heart to the kidneys for nutrition and cellular respiration. Renal veins carry deoxygenated blood after waste products have been removed via glomerular filtration back from the kidneys to the heart.

The afferent arteriole is the arteriole that brings blood to the glomerulus. ... The efferent arteriole is the arteriole that carries blood away from the glomerulus. It is smaller in diameter than the afferent arteriole.

High blood pressure (hypertension) is a leading cause of kidney disease and kidney failure (end-stage renal disease). Hypertension can cause damage to the blood vessels and filters in the kidney, making removal of waste from the body difficult.

kidneys: two bean-shaped organs that filter waste from the blood and produce urine. ureters: two thin tubes that take pee from the kidney to the bladder. bladder: a sac that holds pee until it's time to go to the bathroom. urethra: the tube that carries urine from the bladder out of the body when you pee.

Your kidneys are shaped like beans, and each is about the size of a fist. They are near the middle of your back, one on either side of your spine, just below your rib cage. Each kidney is connected to your bladder by a thin tube called a ureter.
