A

Movement

26
Q

It is the Characteristics of Life where it react to internal or external change

A

Responsiveness

27

37
Q

The most abundant chemical in the body

A

Water

38
Q

How many percent of water our body needed

A

60%-75%

39
Q

Provides the body with needed nutrients. Needed for energy, raw building materials for growth and repair, and to regulate chemical reactions

A

Food

40
Q

Force applied to something

A

Pressure

41
Q

It is a pressure which is needed for breathing

A

Atmospheric Pressure

42
Q

It is a pressure which is needed to move blood through blood vessels, our blood pH

A

Hydrostatic (Water) Pressure

43
Q

As our body shivers our temperature increases

T or F

A

True

44
Q

As our body sweat the temperature decreases

T or F

A

True

45
Q

It is the maintenance of a variable, such as body temperature around an ideal normal value, or set point. It is the existence and maintenance of a relatively constant environment within the body.

A

Homeostasis

46
Q

Homeostatic control mechanisms have at least 3 interdependent components

A

Receptor
Integrating/Control Center
Effector

47
Q

One of interdependent where it senses environmental stimuli, sending the information to the control/integrating center (eg. Peripheral Chemoreceptors, which detect changes in Blood pH)

A

Receptor/Sensor

48
Q

One of interdependent where it receives information from the senses and initiates the response to maintain homeostasis (eg. Hypothalamus)

A

Control/Integrating Center

49
Q

It is a region of brain that controls everything from body temperature to heart rate, Blood pressure, satiety (fullness) and circadian rhythm (sleep and walk cycle)

A

Hypothalamus

50
Q

One of the interdependent where any organ or tissue that receives information from the integrating/control center and acts to bring about the changes needed to maintain homeostasis (eg. Kidney, which retains water if blood pressure is too low)

A

Effector

51
Q

It brings a system back to it’s level of normal functioning. It is also a balance, maintain homeostasis
(Eg. Blood pressure, metabolism, body temperature

A

Negative Feedback

52
Q

It enhances or accelerates output created by an activated stimulus
(Eg. Platelet aggregation and accumulation in response to injury)

A

Positive Feedback
