The Renal System Flashcards
1
Q
What are the primary functions of the Kidneys?
A
- Excretion
- Acid-Base balance
- Osmoregulation
2
Q
What is Glomerular filtration?
A
- Filtration of blood based on size
- Glomerulus to Bowman’s capsule
- Passive, non-selective bulk flow from blood to filtrate
3
Q
What is Tubular Reabsorption?
A
- Useful substances from filtrate back to blood
- Selective… choose what we want to take back
- By passive transport through membrane
- By carrier proteins
4
Q
What is reabsorbed in the nephrons?
A
- Most water 99%
- Most ions
- All nutrients
- 50% of urea
5
Q
What is Tubular Secretion?
A
- From blood to urine
- Removes solutes according to body’s needs
6
Q
What are the three forces in filtration?
A
- Glomerular Hydrostatic Presssure
- Capsular Hydrostatic Pressure
- Colloid Osmotic Pressure
7
Q
What are the 3 ways to regulate Glomerular Filtration Rate?
A
- Renal Autoregulation
- Sympathetic Regulation of GFR
- Hormonal Regulation
8
Q
What is the pH of blood controlled by?
A
The renal and respiratory system
