The Amazing Human Body
Biology 160
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 organdetermine 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?
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?
