Outer layer of kidney tissue just under the capsule. Looks granular due to presence of the glomeruli.
Enters the kidney and becomes the arcuate arteries which then become the afferent glomerular arterioles which then form the glomerulus.
Hollow expandable organ. Smooth muscle. Lies at the cranial brim of the pelvis. Apex is cranial. Caudal portion is called the neck.
Basic functional unit of the kidney. Approx. one million in each kidney. Is a tube used for collecting waste from the blood and converting it into urine.
A tuft of capillaries located in the cortex. Afferent and Efferent arterioles that go to and from it. These capillaries are "leaky."
The funnel portion of a set of tubules that process the "filtrate" to convert it to urine.
Longest section of the nephron. Found in the cortex. Reabsorbs many things the body wants to conserve.
Loop of Henle
U shaped tube with a descending limb that is thin walled and a thick ascending loop. Extends into the medulla. Contains the most concentrated solution in it's lowest area. Is responsible for the concentration of our urine.
Many neprhons dump their wastes into each collecting ducts. Straight. Pass through the medulla to reach the pelvis.
Area around the tubules and the blood vessels in the kidney. Area where things that are conserved get removed from the filtrate within the tube.
Necessary for homeostasis. Necessary to excrete wastes and extra water. Filtration, reabsorption. secretion take place.
blood flow to kidneys, blood pressure
What does the amount of filtration through the kidneys depend on?
What is the ability of a substance to be removed from the blood by the kidney and excreted in the urine.
What is an increase in nitrogenous wastes in the blood typically where 75% of all nephrons are damaged?
What is azotemia with other physical signs such as uremic breath, acidosis, and oral ulceration?
What is very dilute urine that can be a permanent condition where typically 67% of nephrons are damaged?
