What else can I help you with?
What does the medullla in the kidney do?
the renal medulla contains capillaries and urine forming tubules
What does peritubular capillaries do?
This capillary network surrounds the tubules and plays an important role in secretion and reabsorption, plus it delivers oxygen to kidney cells.
Why do you think capillaries surround the long tubules of nephron?
The kidney's function in filtration. The renal tubules located with in the kidney's and also known as nephrons, are the functioning units of the kidney's. Blood carries nutrients and waste. The renal tubules are surrounded by a capillary network so the blood can expel the waste material that is collects from the body. the renal tubules also replace nutrients and water that is still needed back into the capillaries.
What is diabetic nephrology?
It is a progressive kidney disease caused by damage to the capillaries in the kidneys glomeruli.
Is simple cuboidal found lining kidney tubules?
Yes, simple cuboidal epithelium is found lining the kidney tubules. These cells provide absorption and secretion functions in the kidneys, helping with the filtration and reabsorption of substances in the urine.
Where is urine excreted in the kidney?
excretion of urine does not occur in kidneys. Urea and wastes and urine are filtered in the renal corpuscle of the nephron tubule in the kidney. The wastes that are secreted into the tubules and not reabsorbed travel down tubules to urethra and excreted outside of body by urination.
What are nephritis and nephrosis?
Nephritis is inflammation of the kidneys, often caused by infections or autoimmune diseases. Nephrosis is a condition where there is abnormal leakage of protein into the urine due to damage to the kidney's filtration system. Both conditions can lead to kidney dysfunction and require medical management.
What is the most abundant blood vessels in the kidney?
The most abundant blood vessels in the kidney are the peritubular capillaries, which surround the renal tubules and are involved in reabsorption and secretion of substances during the process of urine formation. These capillaries receive blood from the efferent arterioles of the glomerulus.
What is the knot of coiled capillaries found in the kidneys and forms the filtrate?
This is a tuft of capillaries called the glomerulus. The glomerulus is one of the key structures that make up the nephron, the functional unit of the kidney.
What are the tiny structures in the kidneys where the blood is actually filtered and urine is formed?
Glomerulus are tufts of capillaries in the kidney nephrons that filter blood.
What is the plural form of kidney?
kidneys is the plural of kidney.
What is the function of the glomerulus and the bowmans capsule?
The glomerulus and bowmans capsule are part of the excretory system, and they are found in the nephron of a kidney. The function of the glomerulus and the bowman's capsule is to filter the substances in the blood. The glomerulus is a tangle of capillaries which have little slits in them. Water, salts, glucose and urea pass through the slits into the bowmans capsule, which leads to kidney tubules. Then, as the kidney tubules are surrounded by capillaries, the useful substances (all glucose, some salts, most water) are re-absorbed, and only urea and some salts carry on to be excreted.
