ANSWERS
What is the renal system? A group of organs that filter blood to remove waste and maintain fluid and
chemical balance in the body
, What are the functions of the renal system? 1. Filters blood
2. Removes waste
3. Maintains homeostasis
How would we describe the kidney? - Highly vascular (has many blood vessels
- Highly perfused organ (gets a lot of blood flow)
- Rich blood supply (has plenty of blood going to it)
Why does the kidney have many blood vessels? Because its main job is to filter the blood
Why does the kidney need a lot of blood flow? To remove waste products (like urea)
The kidney helps to balance? - Water
- Salts
- pH
The kidney filters blood continuously to make what? Urine
Having more blood vessels does what for the kidney? It helps it have faster and more efficient filtering
What happens as blood moves through the kidney? - Waste is removed
- Filtration occurs
The kidney's evolutionary purpose is too... Remove metabolic waste (especially nitrogenous waste)
Nitrogenous Waste Made when the body breaks down proteins for energy, and needs to be removed
from the blood because it's toxic in high amounts
What is a type of nitrogenous waste? Urea
Nitrogenous waste is the end product of? Amino acid metabolism
