A
Ectotherms gain or lose heat from or to their external environment
2

Endotherms generate their own heat from metabolic reactions
3
Q
Filtration
A
Filtration means that water and small molecules pass (under high pressure) from the blood into the nephron
4
Q
Reabsorption
A
Reabsorption means that molecules pass from the nephron back into the blood
5
Q
Active transport
A
Active transport means that energy (in the form of ATP) is used to move molecules, often against a concentration gradient, i.e from low concentrations to high concentrations
6
