Lesson One

Front 1

Explain the principle of complementarity

Back 1

That you can study anatomy without physiology but they really are inseparable because function always reflects structure.

Front 2

In increasing order of complexity name the different levels of structural organization that make up the human body

Back 2

Atoms --> molecules --> cells --> tissues --> organs --> organ systems --> organisms (i.e. humans )

Front 3

List the 11 organ systems of the body and briefly explain the major function of each system

Back 3

1. Cardiovascular/circulatory = transports nutrients & wastes, hormones &gases

2. Digestive = extracts and absorbs nutrients from food, removes wastes and maintains water &chemical balances

3. Endocrine = regulates body temperature, metabolism, development, reproduction, and maintains homeostasis

4. Excretory = removes wastes from blood, regulates concentrations of body fluids

5. Lymphatic/Immune = defends against pathogens

6. Integumentary = protects against injury, infection, and fluid loss. Helps regulate body temperature

7. Muscular = moves limbs and trunk, moves substances thru body, provides structure and support

8. Nervous = regulates behavior, maintains homeostasis, controls sensory and motor functions

9. Reproductive = produces gamete and offspring

10. Respiratory = moves air in and out of lungs, controls gas exchange between blood and lungs

11. Skeletal = protects and supports the body and organs

Front 4

Compare and contrast negative and positive feedback and describe the role of each in maintaining body homeostasis

Back 4

In negative feedback the output shuts off the original stimulus or reduces it's intensity. Most homeostatic control mechanisms. I.e. regulation of body temperature and control of blood volume.

In positive feedback the response enhances the original stimulus so that the activity(output) is accelerated. Aka waterfall effect. I.e. blood clotting and labor contractions

Front 5

Appraise the relationship between homeostatic imbalance and disease

Back 5

Homeostatic imbalance is a disturbance in homeostasis. Homeostasis is so important most diseases can be regarded as a result of its disturbance.

Front 6

Define anatomical terminology including anatomy, physiology, the anatomical position.

Back 6

Anatomy= the study of body structures

Physiology= the study of the functions of living organisms

Anatomical position= the body is erect with feet slightly apart with palms facing forward and thumbs point away from the body.

Hint 6

Front 7

Name the nine regions and four quadrants of the abdominopelvic cavity and list the organs they contain

Back 7

1. Region

Front 8

Describe the structure of the cell and explain how it relates to function

Back 8

The cell is made up of

Front 9

Compare and contrast positive and negative feedback and describe the role of each in maintaing body homeostasis

Back 9

Negative feedback is when
