15.5 The Structure And Function Of The Mammalian Kidney Flashcards
What supplies the Kidney with blood
Renal arteries
What are the cells of the kidney
Nephrons
These act as filtering units
What does the kidney make
Urine which passes out of the kidneys down the uterus
What does the medulla of the kidney contain
Tubules of nephrons that form the pyramids of the kidney and a collecting duct
Lighter colour
What happens in the cortex of the kidney and why does it contain
Where filtering of blood takes place
There is a dense capillary network that carries blood from renal artery to nephrons
What is the pelvis of the kidney
The central chamber where ur one is collected before leaving
What is the job of nephrons
Blood is filtered
Why are the parts of the nephron
Bowmans capsule Proximal convoluted tube Loop of henle Distal convoluted tube Collecting duct
What is the bowmans capsule
Cup shaped structure that contains the glomerulus
What is the glomerulus
Where ultrafiltration takes place
What is the proximal convoluted tube
The first coiled region of the tubule found in the cortex where many substances are reabsorbed
What is the loop of henle
A long tubule that creates a region of very high solute concentration in the tissue fluid in the medulla part of the nephron
What is the distal convoluted tube
Where fine tuning of water balance of the body takes place
The permeability of the walls to water varies in response to levels of antidiuretic hormone
What is the collecting duct
Where urine passes down and more fine tuning of water takes place
What happens to the blood that leaves the kidneys
It has reduced urea levels but other substances are the same amount that
