Organization of the Human Body Worksheet

1. Explain the difference between anatomy and physiology. Anatomy is the study of the structures of the human body and physiology is the study of the function of the body's parts.

2. Please organize the following structures in order from smallest to largest: system, tissue, organ, and cell. Cell, Tissue, Organ, System.

3. In the term physiology the suffix -logy means what? Study of.

4. What is the type of membrane that lines all of the passages leading the exterior? Mucous membrane.

5. What do you call a mass of cells that all perform the same function? Tissue.

6. What type of tissue is specialized for the conduction of nerve impulses? Nerve tissue.

7. The term epidermis contains a prefix and a root term. What is the root in this word and what
does it mean? Derm - skin.
What is the prefix in this word and what does it mean? Epi - upon.

8. The term cavity appears frequently in this lesson. What does it mean? A hollow space/area.

9. Name the four main types of tissue and describe their function.

Epithelial: Lies the outside of your body and some things on the inside. Purpose: protection/waterproofness (that's a new word)/ and temperature regulation.

Connective: Supports and protects bones, fat, and cartilage. (Internal.)

Muscle: For muscles. Purpose: contraction and flexibility.

Nerve: An internal tissue designed for recieving nerve impulses.

10. A cell is made of ----- except for the nucleus which is made of -----. (I really couldn't figure this one out. I'm sure the answer is simple, but I couldn't seem to find it out.)

11. What type of membrane lines joint cavities and outer surfaces of bones? Connective.

12. What is an organ system? Several organs working together in the body to do a specific task(s).

13. Name the five types of membranes and where each is located.

1. Cutaneous - the external layer of skin.

2. Mucous - lines all passages leading to the exterior of the body.

3. Serous - Lines bodily cavities and the organs in them.

4. Fibrous - Lines joint cavities and the outer surface of bones.

5. Fascia - Lines muscles, glands, blood vessels, and nerves.

14. What is the function of the cell membrane? The nucleus? The cell membrane surrounds and protects the cell, and also allows certain things to go in and out of the cell. The nucleus is the control unit of the cell. It tells the cell what to do and how to do it.

15. The cutaneous membrane is made of two distinct layers. Name each of these layers and describe what they are made of.

Epidermis - made of many layers of cells. Contains the sweat pores and hair folicles + hair.

Dermis - made of connectice tissue and microscopic organs (sweat glands, sebaceous glanes, etc)
