(Homeostasis)

Introduction

The internal environment of multi-cellular organisms is made
up of tissue fluids whose conditions, such as pH, temperature,
pressure, glucose concentration and salt contents, are always kept
at a relatively constant level regardless of the fluctuations of the
external environments. The ability to maintain a constant internal
body environment enables an organism to survive in a variety of
habitats. In this chapter, you will learn about body regulation in
mammals which include feedback mechanisms, urine formation,
and osmoregulation. The competences developed will enable you
to adapt, and survive in different environments.

Student activities
(a) Explaining the concept of regulation in mammals
(b) Exploring mechanisms of urine formation, osmoregulation and
feedback mechanisms

(c) Carrying out anatomical and physiological investigation related
to excretory system in mammals
