Question
Chapter 33, Problem 1PIT
Summary Introduction
To determine:
How do the urinary system and the circulatory system work together to maintain homeostasis.
Concept introduction:
Homeostasis is the phenomenon in which, the maintenance of a constant internal environment within a living organism is maintained. Thermoregulation in organisms is an example of homeostasis in which, internal body temperature of an organism is regulated.
