Physiology

 is the study of the functions of the human body (the mechanisms by which the various organs

and tissues carry out their specific activities) In order for the body to function normally, the
internal environment must be regulated to become relatively constant.

Why?

Homeostasis Role of Systems in homeostasis
Homeo → (human cell) Different body systems (except reproductive system) share in

maintaining homeostasis. For example:
Stasis →

▪ The gastrointestinal tract → digest food to provide the body
 Tendency to maintain
with nutrients.
constant environmental
▪ The respiratory system → obtain oxygen and removes
condition of the cell.
carbon dioxide.
➢ Many variables such as:
▪ The cardiovascular system → transports all these materials
body temperature, blood
and others from one part of the body to another.
pressure, blood glucose,
▪ The urinary system→ eliminates wastes products and plays a
oxygen, carbon dioxide
role in regulation of blood volume and blood pressure.

Regulation

 The activities of body system are regulated by two systems (maestro)
1- The nervous system.

2- The endocrine system.
