What is the Relationship Between Form and Function in Nature

Leafy Sea Dragon

Where/How do you think this animal lives?

Key Course Themes

• 1. Form and Function Examples?

• 2. Maintenance of Homeostasis Example?

What is A and P

• Anatomy: the study of the structure and shape of the body and body parts

• Physiology: the study of how the body and it parts function

Levels of Organization

• Atoms molecules cells

• Cells tissues organs

• Organs organ systems organism

• Organism population ecosystem

12 Body Systems

Integumentary Skeletal Muscular

Nervous Endocrine Cardiovascular

Lymphatic Respiratory Digestive

Urinary Reproductive

Reproductive

Assignment• Group Work: For Each Organ System: 1. List one organ contained in this body system

2. For that particular organ- determine the function and then explain how the structure of the organ aids the function of that organ

Necessary Life Functions

• What does a bacteria need to stay alive?

• What does a species of bacteria need to survive?

Did You List All The Functions Needed to Survive and Maintain Life

1. Keep the “inside” in and the “outside” out

2. Movement (what about plants?)

3. The “Poke me test”- sense and respond

Did You List All The Functions Needed to Survive?

4. Digestion- ability to extract energy and nutrients from food (what about plants?)

5. Metabolism: sum of all chemical reactions atoms molecules cells molecules atoms

6. Elimination of waste: excretion

Did You List All The Functions Needed to Survive?

7. Reproduction: survival of the individual or the species?

8. Growth and Repair

Assignment• Group Work: For Each Function: See Figure 1.4

1. For each life function give a specific example of how that function contributes to the ongoing maintenance of homeostasis of one specific set point (variable). Example:

Body Cavities

1. Why is the Cranial Cavity a different color

2. What separates the Thoracic cavity form the abdominal cavity?
