Structural and functional units of the kidneys
Nephrons
Nephrons is composed of what
- Renal Corpuscle
- Renal Tubule
Actual site for filtration
Renal corpuscle
What does renal corpuscle consist of
- Glomerulus
- Glomerular Capsule
Knot of capillaries made of podocytes
Glomerulus
Arises from a cortical radiate artery and feeds the glomerulus
Afferent Arteriole
Receives blood that has passed through the glomerulus
Efferent Arteriole
Cup-shaped hollow structure that completely surrounds the glomerulus
Glomerular Capsule
First part of the renal tubule
Glomerular Capsule
Where renal tubule ends
Collecting duct
Medial indentation where several structure enter and exit the kidney
Renal Hilum
Where secretion and absorption takes place
Peritubular capillaries
What way does blood enter the glomerulus through podocytes?
Passive Diffusion
Nonselective, passive process in which fluid passes from the blood in the glomerulus to the glomerular capsule
Glomerular Filtration
What can pass through glomerulus
Water, Glucose, Amino Acids, Ions
What cannot pass through glomerulus
Proteins, Blood Cells
Refers to the blood pressure
Hydrostatic Pressure
Decrease in urine output
Oliguria
No urine output
Anuria
Excessive urine output
Polyuria
Transports needed filtrates into the tubule cells (urine to blood)

What substances secreted in DCT?
Potassium
Trigger for Aldosterone Release caused by low blood pressure
Renin Angiotensin Aldosterone System
What does RAAS release?
Renin
What converts Angiotensinogen to Angiotensin I
Renin
What converts Angiotensin I to Angiotensin II
ACE (Angiotensin Converting Enzyme)
