51
Q

Define homeostasis and explain its
importance to survival

A

A state of balance within all physical systems of the body, maintaining the body’s equilibrium

52
Q

Describe the difference between negative
and positive feedback mechanisms

A
  • Negative feedback is a biological response to stimulus that works to prevent it’s effects and return the body’s equilibrium
  • Positive feedback is a biological response the enhances the response to the stimulus until an end point
53
Q

Identify and describe the components of a
homeostatic mechanism, and explain how they interact to maintain homeostasis

A

Stimulus - Produces change in variable
Receptor - Detects change
Input - Information is sent along afferent pathway to control center
Output - Information is sent along efferent pathway to effector
Response - Of effoctor feeds back to reduce the effect of stimulus and returns variable to homeostatic level

54
Q

Differentiate between an acid and a base

A

Have a pH <7, base is the chemical opposite

55
Q

Explain the concept of pH and state the pH of blood.

A

Blood pH is 7.1 (7.35-7.45)
