25
Q

It is basically a tube running through the body from mouth to anus. Their role is to break down food and deliver the resulting nutrients to the blood.

A

DIGESTIVE SYSTEM

26
Q

Removes the nitrogen-containing wastes from the blood and flushes them from the body in urine.

Maintains acid-base balance, helps regulate normal blood pressure.

A

URINARY SYSTEM

27
Q

Its role is to produce offspring such as for male reproductive system, their testes produces sperm. Meanwhile, for the females ovaries produces eggs

A

REPRODUCTIVE SYSTEM

28
Q

What are the Necessary Life Functions?

A
  1. Maintaining Boundaries
  2. Movement
  3. Responsiveness (irritability)
  4. Digestion
  5. Metabolism
  6. Excretion
  7. Reproduction
  8. Growth
29
Q

Its “inside” remains distinct from its “outside”. Generally preventing entry of potentially damaging or unnecessary substances.

A

MAINTAINING BOUNDARIES

30
Q

Includes all the activities promoted by the muscular system, such as propelling ourselves from one place to another.

Movement of substances

A

MOVEMENT

31
Q

The ability to sense changes (stimuli) in the environment and then to react to them.

A

RESPONSIVENESS

32
Q

The process of breaking down ingested food into simple molecules that can then be absorbed into the blood. Breakdown and absorption of nutrients

A

DIGESTION

33
Q

Refers to all chemical reactions that occur within the body and all of its cells. Breaking down complex substances into simpler building blocks, making large structures from smaller ones

A

METABOLISM

34
Q

The process of removing excreta or wastes from the body. Wastes may be removed in urine, feces, or sweat

A

EXCRETION

35
Q

The production of offspring; occurs on cellular level or organismal level

A

REPRODUCTION

36
Q

Increases in cell size or in body size. Hormones play a major role

A

GROWTH

37
Q

What are the Survival Needs?

A
  1. Nutrients
  2. Oxygen
  3. Water
  4. Normal Body Temperature
  5. Atmospheric Pressure
38
Q

Two Types of Metabolism

A

Catabolism & Anabolism

39
Q

It is which the body takes in through food, contains the chemicals used for energy and cell building.

Include carbohydrates, proteins, lipids, vitamins, and minerals

A

NUTRIENTS

40
Q

It is required for chemical reactions; made available by the cooperation of the respiratory and cardiovascular systems

A

OXYGEN

41
Q

It accounts for 60 to 80 percent of body weight; most abundant chemical in the human body.

Provides fluid base for body secretions and excretions

A

WATER

42
Q

37ºC (98.6ºF) - below this temperature, chemical reactions slow and stop; above this temperature, chemical reactions proceed too rapidly

A

NORMAL BODY PRESSURE

43
Q

True or False

If body temperature is too high, chemical reactions proceed to rapidly and body proteins begin to break down

A

TRUE

44
Q

The force exerted on the surface of the body by weight of air; must be appropriate for gas exchange

A

ATMOSPHERIC PRESSURE

45
Q

True or False

Breathing and the exchange of oxygen and carbon dioxide in the lungs depend on appropriate atmospheric pressure

A

TRUE

46
Q

It describes the body’s ability to maintain relatively stable internal conditions even though the outside world is continuously changing.

Dynamic state of equilibrium, or balance

A

HOMEOSTASIS

47
Q

Necessary for normal body functioning and to sustain life

A

HOMEOSTASIS

48
Q

What are the Main Controlling System of Homeostasis?

A

NERVOUS AND ENDOCRINE SYSTEM

49
Q

What is the literal translation of homeostasis?

A

“Unchanging”

50
Q

What is the meaning of homeo, and stasis?

A

homeo = the same ; stasis = standing still

51
Q

True or False

Not every organ system plays a role in maintaining the constancy of the internal environment

A

False

52
Q

The disturbance in homeostasis results in disease

A

HOMEOSTATIC IMBALANCE

53
Q

What are the atleast THREE components of homeostatic control mechanisms?

A
  1. RECEPTOR
  2. CONTROL CENTER
  3. EFFECTOR
54
Q

A type of sensor that monitors and responds to changes in the environment (stimuli); and sends information to control center along an afferent pathway

A

RECEPTOR

55
Q

This component analyzes the information it receives and then determines the appropriate response or course of action

A

CONTROL CENTER

56
Q

What pathway information flows from control center to the effector?

A

EFFERENT PATHWAY

57
Q

It provides the means for the control center’s response. The results of the response then feedback to influence the stimulus.

A

EFFECTOR

58
Q

What are the Homeostatic control mechanisms?

A

NEGATIVE FEEDBACK AND POSITIVE FEEDBACK

59
Q

They are rare in the body because they tend to increase the original disturbance (stimulus) to push the variable farther/

Reaction occurs at a faster rate

A

POSITIVE FEEDBACK

60
Q

In positive feedback what does it occur?

A

Blood clotting and during the birth of a baby

61
Q

It includes most homeostatic control mechanisms; shuts off the original stimulus or reduces the intensity

A

NEGATIVE FEEDBACK
