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?
