What 4 factors go into autoregulation of the Glomerular filtration rate (GFR)
Give this one a try later!
, 1. myogenic response
2. tuboglomerular feedback
3. hormones
(angiotensin 2, prostaglandins)
4. autonomic neurons
(sympathetic- decreases urine in fight/flight)
Give 3 characteristics of anatomy of the bladder
Give this one a try later!
1. Bladder is made up of transitional cells (can expand/contract)
2. Internal sphincter (opened by pressure of contracting bladder)
3. External sphincter (controlled by skeletal muscle)
Clearance:

Rate at which a substance is "cleared"/leaves the blood
Where should colloid osmotic pressure be the highest?
Give this one a try later!
Inside the capillaries
, What happens to filtration with the constriction of the afferent arterials
Give this one a try later!
= decrease in pressure
= less filtration
If clearance = GFR, what is the equation for clearance?
Give this one a try later!
Clearance = (Vu x Ui) / Pi
Clearance = (volume of urine x urine concentration) / plasma concentration
What are the 4 major functions of the kindeys?
Give this one a try later!
1. Homeostasis of water and ions (osmolarity maintenance)
2. pH balance
3. "Waste" and foreign substance removal
4. Producing hormones
Keep in mind that filtrate and blood travel in ____________ directions
