Q

What is anatomy

A

Structure

20
Q

What is physiology

A

Function

21
Q

How do physiology and anatomy work together to make an item work

A

Structure determines what function can occur

22
Q

What is the relationship between the levels of organization?

A

Each level makes up the one after it

23
Q

What is the anatomy of a backpack?

A

Zippers pockets straps

24
Q

What is the physiology of a backpack

A

Carries things; put arms through to hold

25
Q

What processes characterize living things? 6

A
Metabolism
Responsiveness 
Movement
Growth
Differentiation 
Reproduction
26
Q

What’s an example of metabolism

A

Changing glucose to energy

27
Q

What’s an example of responsiveness

A

Feedback loop (body detecting and responding to change)

28
Q

What’s an example of movement

A

Motion of whole body; walking

29
Q

What’s an example of growth

A

Increase in body size

30
Q

What’s an example of differentiation

A

Unspecialized cells becoming specialized

31
Q

What’s an example of reproduction

A

Your skin making new cells to repair an open wound

32
Q

What is homeostasis

A

Maintaining a relatively stable condition

33
Q

How do homeostasis and feedback systems differ?

A

Homeostasis resists change while feedbacks change in order to maintain a stable condition

34
Q

What is he relationship between homeostasis and feedback systems ?

A

Feedback systems adjust its performance to meet a desired output response leading to homeostasis

35
Q

3 components of a feed back system and their functions

A

Receptors - detect
Control center - assesses
Effector- changes

36
Q

What’s the relationship between the 3 components of a feedback system?

A

They all work together to return to homeostasis

37
Q

What initiated a feedback system?

A

Stimulus

38
Q

Difference between positive and negative feedback system? Give example

A

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

39
Q

How does diabetes relate to homeostasis

A

Diabetes affects homeostasis by disrupting blood sugar levels

40
Q

Blood sugar too low what is the receptor? And what does it detect?

A

Pancreas; low blood glucose

41
Q

Blood sugar too low what’s the control center? And what does it do?

A

Pancreas released glucagon to liver cell

42
Q

Blood sugar too low what’s the effector? What does it do?

A

Glucagon increases glucose release from liver cell

43
Q

Blood sugar too Hugh what’s the receptor? What does it detect?

A

Pancreas; blood glucose too high

44
Q

Blood sugar too high what’s the control center? What does it do?

A

Pancreas releases insulin to muscle cell

45
Q

Blood sugar too Hugh what’s the effector? What does it do?

A

Insulin increases absorption of glucose into muscle cell

46
Q

Difference between type 1 & 2 diabetes

A

1: born with it, pancreas cannot produce insulin
2: insulin resistant; get older; can be from bad food habits

47
Q

How can you avoid type 2 diabetes ?

A

Manage weight, exercise
