What is the capillary network that surrounds the renal tubules called?
Within the glomerulus, the network of capillaries is called the glomerular capillary bed. Once the efferent arteriole exits the glomerulus, it forms the peritubular capillary network, which surrounds and interacts with parts of the renal tubule.
Which type of capillary network is found in the kidney?
The glomerulus (plural glomeruli) is a network of small blood vessels (capillaries) known as a tuft, located at the beginning of a nephron in the kidney. Each of the two kidneys contains about one million nephrons.
What surrounds the tubules of the nephron?
At one end of each nephron, in the cortex of the kidney, is a cup shaped structure called the (Bowman’s or renal) capsule. It surrounds a tuft of capillaries called the glomerulus that carries high-pressure blood.
What is the network of capillaries that are formed when the renal efferent Arteriole of a cortical nephron divides?
The efferent arterioles divide to form a network of capillaries, called the , which surround tubular portions of the nephron in the renal cortex. Extending from some efferent arterioles are long loop-shaped capillaries called that supply tubular portions of the nephron in the renal medulla.
Does the kidney have capillaries?
The nephrons include tiny coiled tubes of capillaries and their associated tubules. Each kidney has approximately 1 million of them. The nephrons regulate waste, water, and other materials in the blood and urine to adjust to the body’s changing needs.
What is the correct order of the renal tubule regions?
proximal convoluted tubule (red: found in the renal cortex) loop of Henle (blue: mostly in the medulla) distal convoluted tubule (purple: found in the renal cortex) collecting tubule (black: in the medulla)
Where are the 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 are the vasa recta found?
The vasa recta, or arteriolae rectae renis, are peritubular capillaries in the kidneys that are situated parallel to and surrounding the loop of Henle.
What is the network of capillaries that are formed when the renal efferent arteriole of a cortical nephron divides quizlet?
What is the capillary bed that produces the filtrate that enters the urinary tubules of the nephron?
glomerulus
Nephron structure – capillary bed called glomerulus. It is covered by the end of the renal tubule called the Bowman’s capsule.
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.
