1

Define and compare anatomy and physiology
a. Explain why they are usually studied together

Anatomy is the science behind the structure of the human body, while physiology is the study of the functions of the human body. They are often studied together because they are very closely linked

2

Define tissue

Tissue: any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products.

3

What are the 4 main categories of animal tissue (note examples)

1. Epithelial :: epidermis
2. Connective :: the tissue that holds your organs in place
3. Muscle tissue :: cardiac muscle, skeletal muscle
4. Nervous :: nerve cells, nervous tissue

4

Describe the relationship among tissues, organs, and organ systems

Organ systems are comprised of organs, which are comprised of diffent types of tissue. Without cells there would be no tissue, without tissue there are no organs, without organs there would be no organ systems
