Atoms Molecules Organelles Cells Tissue Organs Organ system Organism
What’s an example of an atom
Carbon
What’s an example of molecules
Water
What’s an example of organelles
Nucleus
What’s an example of cells
Nucleus
What’s an example of tissue
Muscular
What’s an example of organs
Heart
What’s an example of organ system

What’s an example of organism
Bacteria
What is anatomy
Structure
What is physiology
Function
How do physiology and anatomy work together to make an item work
Structure determines what function can occur
What is the relationship between the levels of organization?
Each level makes up the one after it
What is the anatomy of a backpack?
Zippers pockets straps
What is the physiology of a backpack
Carries things; put arms through to hold
What processes characterize living things? 6
Metabolism Responsiveness Movement Growth Differentiation Reproduction
What’s an example of metabolism
Changing glucose to energy
What’s an example of responsiveness
Feedback loop (body detecting and responding to change)
What’s an example of movement
Motion of whole body; walking
What’s an example of growth
Increase in body size
What’s an example of differentiation
Unspecialized cells becoming specialized
What’s an example of reproduction
Your skin making new cells to repair an open wound
What is homeostasis
Maintaining a relatively stable condition
How do homeostasis and feedback systems differ?
Homeostasis resists change while feedbacks change in order to maintain a stable condition
What is he relationship between homeostasis and feedback systems ?
Feedback systems adjust its performance to meet a desired output response leading to homeostasis
3 components of a feed back system and their functions
Receptors - detect
Control center - assesses
Effector- changes
What’s the relationship between the 3 components of a feedback system?
They all work together to return to homeostasis
What initiated a feedback system?
Stimulus
Difference between positive and negative feedback system? Give example
Negative - reverse ex) too cold warm up body by shivering
Positive - end products of an action cause more of tang action to occur ex) child birth; contraction
How does diabetes relate to homeostasis
Diabetes affects homeostasis by disrupting blood sugar levels
Blood sugar too low what is the receptor? And what does it detect?
Pancreas; low blood glucose
Blood sugar too low what’s the control center? And what does it do?
Pancreas released glucagon to liver cell
Blood sugar too low what’s the effector? What does it do?
Glucagon increases glucose release from liver cell
Blood sugar too Hugh what’s the receptor? What does it detect?
Pancreas; blood glucose too high
Blood sugar too high what’s the control center? What does it do?
Pancreas releases insulin to muscle cell
Blood sugar too Hugh what’s the effector? What does it do?
Insulin increases absorption of glucose into muscle cell
Difference between type 1 & 2 diabetes
1: born with it, pancreas cannot produce insulin
2: insulin resistant; get older; can be from bad food habits
How can you avoid type 2 diabetes ?
Manage weight, exercise
