aka leukocytes do not contain hemogobin, much less numerous than red blood cells (outnumbered 1000 to 1) fight disease by finding pathogens and can live for days, months, or even years.
fight infections through inactivating foreign substances or cells

Q

mouth

A

start of the digestive system
break down food in which helps the food be digested in the body
produces saliva, which breaks down the chemicals in the food a bit, which helps make the food mushy and shallow

40
Q

esophagus

A

a long think and muscular tube that connects the pharynx/throat to the stomach
food and fluids are propelled through the esophagus into the stomach

41
Q

esophagus

A

a long think and muscular tube that connects the pharynx/throat to the stomach
food and fluids are propelled through the esophagus into the stomach

42
Q

stomach

A

a muscular sac that lies between the esophagus and the small intestine in the upper abdomen
releases acids and enzymes for the chemical breakdown of food
can expand to temporarily hold food
important for churning food into a consistency that is easier to digest for the rest of the body systems

43
Q

small intestine

A

absorbs about 90% of the nutrients from the food we eat
the location in the body where the majority of the nutrients from ingested food are absorbed
digested food passes through the wall of the intestine into the blood vessels through diffusion and active transport which then distribute the nutrition first, to the liver and then through the rest of the body.

44
Q

large intestine

A

performs the vital task of absorbing water and vitamins while converting digested food into waste (feces)
as your body takes back water, it just leaves waste products behind. these become dryer and harder so it is easier for your body to get rid of them

45
Q

respitory system function

A

allow animals to move oxygen (needed for cellular respiration) into body tissues and remove carbon dioxide (waste product of cellular respiration) into cells

46
Q

alveoli

A

moist thin-walled packets which are the site of gas exchange

47
Q

cystic fibrosis

A

one of the most common inherited disorders in the Caucasian population in the U.S. and is inherited

48
Q

hormones

A

chemical signals that influence cells’ activities
produced by glands
travel through the circulatory system
affects cells with matching receptors

49
Q

hormones influence a cell’s activities by

A

entering the cell or binding to its membrane

50
Q

hormones are produced by

A

glands

51
Q

hormones travel through the

A

circulatory system

52
Q

hormoes

A

affect cells with matching receptors

53
Q

negative feedback

A

occurs when the output of a system acts to oppose changes to the input of the system

54
Q

glucose intake occurs

A

during digestion of food that is needed for every expenditure to form routine physical activities

55
Q

organ that regulates glucose levels

A

pancreas

56
Q

the pancreas regulates glucose levels by

A

secreting two hormones insulin and glucagon

57
Q

liver

A

stores excess glucose in form of glycogen to be utilized later

58
Q

A

anything that invades your body & causes a disease

59
Q

contagious

A

infectious

60
Q

people may carry a disease

A

without even knowing it

61
Q

diseases can be spread

A

during the incubation period (before symptoms occur)

62
Q

diseases transmit by

A

direct contact, indirect contact, contact with object, infected animals, and contaminated food or water

63
Q

fungi

A

appear in moist areas like the skin, scalp, mouth, and throat

64
Q

bacteria

A

most are helpful or harmless
a few are pathogens and release toxins in our bodies and are fought by the immune system or can be treated with antibiotics

65
Q

virus

A

a nonliving protein coat surrounding either dna or rna
nonliving
do not grow or develop, obtain or use energy, respond to environment
BUT
have genetic material DNA or RNA
can replicate, but only by using the host cell
can evolve

66
Q

vaccines

A

prevent viral infections
person is injected with a weakened virus
the immune system can later recognize the normal virus and fight it off.

Q

immune system

A

bodies defense sytem against disease

69
Q

skin

A

protective barier

70
Q

fever

A

raises body temperature to kill infection

71
Q

inflammation

A

swelling and redness

72
Q

pathogens

A

things that infect you
contain antigens

73
Q

pathogens

A

things that infect you
contain antigens

74
Q

antigens

A

chemical markers (name tag)
tell where the pathogen is

75
Q

antibodies

A

proteins that recognize and bind to the antigen because they fit together
mark pathogens for destruction

76
Q

b cells

A

make antibodies

77
Q

b memory cells

A

remember antigen in case of second infection

78
Q

helper t cells

A

recognize antigen and tell b cells to make antibodies which attract killer t cells which kills infected self cell by injecting enzymes

79
Q

mensural cycle

A

the rhythmic maturation of eggs

80
Q

fsh

A

follicle stimulating hormone
hormone that matures eggs

81
Q

Q

ovulation

A
84
Q

A

two very thin tubes that serve as a path for the gg from the ovaries to the uterus

85
Q

uterus

A

the muscular organ in which a fetus develops and is nurtured during pregnancy

86
Q

uterus lining

A

the inner tissue in the uterus which builds up in preparation for the implantation of a fertilized and is rich in blood vessels to nurture the embryo
