Question 13

Elimination of Wastes is
Backwards.
Much of the blood volume leaves the body
The \_\_\_takes back the good from the filtrate
leaving the waste to pass out.
Some excess materials are excreted.

Answer 13

nephron

Question 14

Three Functions in the

Urinary System

Answer 14

Filtration - Plasma carrying all dissolved
materials exit the blood

Reabsorption - Good dissolved materials
are retaken

Excretion - some excess dissolved
materials in the blood are excreted.
