Q

Reproduction

A

Produces future generations occurs on cellular level or organismal level

26
Q

Growth

A

increases cell size and number of cells

27
Q

Survival needs

A

Nutrients Oxygen Water Stable body Temperature Atmospheric Pressure

28
Q

Nutrients

A

chemiclas for cell building carbs proteins lipids vitamins minerals

29
Q

oxygen

A

required for chemical reactions

30
Q

Water

A

60-80 of body weight provides for metabolic reaction

31
Q

Atmospheric Pressure

A

must be appropriate for gas exchange

32
Q

Homeostasis

A

maintaining stable environment dynamic state of flux imbalance results in disease

33
Q

Homeostasis Regulation

A

Neural and Hormonal control systems Receptor Control Center Effector

34
Q

Receptor

A

sensor that monitors and responds to changes in environment sends information to control center Brain

35
Q

Control Center Brain

A

Determines set point Level at which variable is maintained Analyzes information determines appropriate response

36
Q

Effector

A

responds to signals from brain afferent IN efferent OUT

37
Q

Feedback Mechanisms

A

Homeostatic mechanisms to keep body levels within a normal range can vary from one person to another positive and negative

38
Q

Negative Feedback mechanism

A

Most common effectors produce response opposite of stimulus bring value back to set point shut off or reduce stimulus

39
Q

Positive Feedback mechanism

A

promotes further push from set point used in blood clotting and child birth Keep clotting until bleeding stops
