Physiology is the study of the --------- of an organism.

Function

Anatomy is the study of body ————.

structure

The structure of a body part is a reflection of its ————-.

function

What are the 6 levels of organization that comprise the human body?

1. Chemical level

2. Cellular level

3. Tissue level

4. Organ level

5. System level

6. Organismal level

Chemical level is basically about smallest basic level of matter which is ——

atoms and molecules

Molecules combine to form ——-.

Cells

Cells are basic ————- and ———— units of an organism.

functional and structural

( —— ) are the smallest units capable of performing all life proccesses.

cells

A group of similar cells that work together to perform a particular function are called a ———.

tissue

what are 4 basic types of tissues?

1. Epithelial

2. Connective

3. Muscular

4. Nervous

Two or more types of tissues make an ———.

organ

function , shape

Related organs with common functions make up ———.

a system.

Any living organism is an ———.

Organism

Interactions between simpler components of the lower levels ot organization make ———. (give example)

emergent properties—- example would be emotions and thoughts

what are 6 important life processes of the human body?

1. Metabolism

2. Responsiveness

3. Movement

4. Growth

5. Differentiation

6. Reproduction

Metabolism is the sum of all of the ———— that occur in the body.

chemical reactions

what are two important phases of metabolism?

Catabolism and Anabolism

Catabolism is the ——-

breakdown of the complex chemical molecules to simpler components.

Anabolism is the ——-.

formation of complex molecules from smaller, simpler components.

Responsiveness is basically …..

ability of the body to detect changes and respond to them.

Movement is actually ….

motion of the whole body, indicidual organs, single cells, and even tiny structures inside cells.

Growth is the increase in ——— and ——— cells.

sice and number

Development of a cell from unspecialized to specialized state is called ——-.

Differentiation

what are stem cells?

unspecialized cells that can divide and turn into specialized cells.

what does reproduction mean?

Means formation of new cells for growth, repair, replacement or production of new individual.

what is homeostasis?

Maintenance of relatively stable conditions in the body’s internal environment.
