3 elements needed for fire

Oxygen, fuel, heat

1

Absorption

Act or process of sucking up or in

2

Aerobic

Requiring oxygen to live and grow

3

Amino acid

Basic component of proteins

4

Anaerobic

Not requiring oxygen to live and grow

5

Antioxidants

Enzymes or organic molecules, help protect body from harmful chemicals (free radicals)

6

Antisepsis

Aseptic control that inhibits, retards growth of, or kills pathogenic organisms

7

Asepsis

Being free from infection

8

Body mechanics

The way the body moves and maintains balance

9

Chain infection

Factors that lead to the transmission or spread of disease

10

Cholesterol

Fatlike substance synthesized in the liver and found in body cells and animal fats

11

Clean

Free from organisms causing disease

12

Contaminated

Containing infection or infectious organisms

13

Digestion

Physical and chemical breakdown of food in preparation for absorption

14

Disinfection

Aseptic-control method that destroys pathogens but does not kill

15

Etiology

Study of the cause of disease

16

Endogenous

Infection or disease originating within the body

17

Ergonomics

Applied science used to promote safety and well-being of people by the environment and preventing injuries

18

Exogenous

Infection or disease originating outside of the body

19

Fat-restricted diet

Diet with limited fats

20

Fungi

Group of plantlike animals living on dead organic matter

21

Hantavirus

Virus spread by contact with rodents or their excretions

22

High-protein diet

Diet containing large amounts of protein-rich foods

23

Idiopathic

Without recognizable cause; self-originating

24

Low-cholesterol diet

Diet restricting foods high in saturated fat

25

Low-protein diet

Diet limits food high in protein

26

Low-residue diet

Limits foods containing large amounts of residue (indigestibles)

27

Metabolism

Use of food nutrients by the body to produce energy

28

Nosocomial

Originating in a health care facility such as a hospital

29

Nutrition

All body processes related to food; body's use of food for growth, development, and health

30

Opportunistic

Acting and taking advantage of opportunities

31

OSHA

Occupational safety and health administration

32

Osteoporosis

Bones become brittle and break easily

33

PASS

-pull the pin
-aim the nozzle
-squeeze the handle
-sweep

34

Pathogen

Disease-producing organisms

35

Protozoa

one celled organisms often found in decayed materials and contaminated water

36

RACE

-rescue anyone in immediate danger
-activate the alarm
-confine the fire
-extinguish the fire

37

Rickettsiae

Microorganisms that live on other organisms

38

Sterilization

Process that results in total destruction of microorganisms

39

Virus

One of a large group of small microorganisms that cause disease

40

Cilia

Hairlike projections

41

Autoclave is good for how long

30 days

42

Chemical disinfection

chemicals that kill everything besides spores and viruses, not a method of sterilization

43

Lipids in body

called triglycerides, or the fats and fatty acids found in the body

44

Importance of water

regulates body functions, essential for digestion of food, helps body tissues absorb nutrients, moves waste material through the body, makes up most of blood plasma and cytoplasm of cells

45

Antibiotics

Powerful medicines used to prevent bacterial infections

46

Basal metabolic rate

(BMR) rate at which the body uses energy just for maintaining its own tissue without doing voluntary work

47

Mechanical digestion

Food is broken down by teeth and moved through digestive system by peristalsis, which is a rhythmic, wavelike motion of the muscles

48

Chemical digestion

Food is mixed with digestive juices secreted by the mouth, stomach, small intestine, and pancreas. Juices contains enzymes which break down food chemically so nutrients are absorbed

49

Sources of protein

Complete protein: meats, fish, milk, cheese, eggs

Incomplete protein: cereals, soybeans, dry beans, peas, corn, nuts

50

Risk factors associated with obesity

Heart disease, diabetes, high cholesterol, high blood pressure, stroke

51

Risk factors of nosocomial infections

Cause serious or life-threatening infections like staphylococcus, pseudomonas, and enterococci, spread to other patients and workers

52

Role of nutrition

Includes all body processes relating to food-digestion, absorption, metabolism, circulation, elimination. These allow the body to use food for energy, maintain good health and growth

53

Portal of exit

Way for the causative agent to escape from the reservoir where it has been growing

54

Portal of entry

Way for the causative agent to enter a new reservoir or host, like breaks in the skin, digestive tract, or respiratory tract

55

Reservoir

Area where the causative agent can live; common reservoirs are humans, animals, environment, fomites

56

Mode of transmission

Way the causative agent can be transmitted to another reservoir or host: direct or indirect contact, air or droplet, vectors, vehicle

57

Best reservoirs

Blood and skin

58

Host

Prison likely to get infection or disease because body defenses are weak

59

Infectious or causative agent

A pathogen, such as bacteria or a virus than can cause a disease
