35
Q

What is the definition of Anatomy?

A

The study of the structure of an organism and the relationship of its parts.

36
Q

What is the definition of Gross Anatomy?

Q

What are the five requirements for an organism to live?

A
  1. Water
  2. Food
  3. Oxygen
  4. Heat
  5. Pressure
52
Q

Why do organisms require water to live?

A

Water is the most abundant substance in the body. It is required for metabolic processes, transport, and to regulate body temperature.
