What is the primary organ of the Urinary system? What is the tract (passage way) of the Urinary system?
Kidneys;
Cortex-> Medulla-> Minor calyx-> Major calyx-> Renal pelvis-> Ureters-> Urinary bladder-> Urethra-> Exterior
What are the functions of the kidney?
Produce urine; controls blood pressure, blood volume, and blood composition
What are the tube like structures that pass through the hilum of the kidney?
renal arteries, renal veins, renal nerves, ureters
what are the 3 layers of the renal pouch, which holds the kidney?
renal capsule, adipose capsule, renal fascia
What unit in the kidney forms urine?
the nephron forms urine in the cortex and renal pyramids of the kidney
Name the functional unit of the kidney
Nephron
What are the main functions of the nephron?
Absorb water, modify blood carried by renal blood vessels, form urine
What are the 2 types of nephrons?
cortical nephron and juxtamedullary nephron
The glomerulus is the body's main _______?
Filter
What are podocytes? What do they do?
cells that form an inner layer. That inner layer covers the glomerulus. Helps control filtration.
What are the functions of the proximal convoluted tubule?reabsorbs water and salt, glucose and other important substancesWhat are the functions of the nephron loop? (Loop of Henle) What are the 2 parts?extends deep into the medulla and reabsorbs water and salt. 2 parts: descending limb and ascending limbYou are a molecule of filtrate. List the structures that you pass in order as you exit glomerulus to the exterior of the body.afferent arteriole -> glomerulus -> proximal convoluted tubule -> descending limb -> ascending limb -> distal convoluted tubule -> collecting ducts -> minor calyx -> major calyx -> renal pelvis -> ureters -> urinary bladder -> urethra -> exterior of the bodyWhat is the function Peritubular capillaries?absorb fluids that have been modified by the nephronWhat is the function of the collecting ducts?receive urine from the nephronsWhat is the function of the urinary bladder? What are the 4 layers of the urinary bladder wall?Store urine. Muscosa, Submucosa. Muscularis externa, SerosaWhat are the 3 layers of the urethra?mucosa, smooth muscularis layer and adventitiaWhat are the main differences between the male and female urethra?female urethra is much shorter. male urethra has 3 parts: prostatic urethra, membranous urethra, penile urethra
