Blood

61
Q

What is blood made out of?

How long does blood travels through your body?

A

Contains cells, fluid, and other substances.

It travels miles and miles of blood vessels to reach every cell in your body.

62
Q

Blood travels throughout your body in tubes called

A

Blood vessels

63
Q

Types of blood vessels

A

Artery, capillary, vein

64
Q

Carry oxygen rich blood away from the heart

A

Arteries

65
Q

Deliver oxygen rich blood to body cells and take oxygen poor blood away from body cells

A

Capillaries

66
Q

Carry oxygen poor blood back to the heart

A

Veins

67
Q

Each heart beat pumps blood into your arteries at high pressure, which is your

A

Blood pressure

68
Q

What are arteries made out of?

A

Have thick walls with a layer of smooth muscle

69
Q

Blood pressure pushes blood through the arteries. Artery walls are ——— and ——– to withstand the pressure. N——–, ——–and other ———- must leave the body cells and are ——— ———by blood.

A

Strong
And stretch
Nutrients, oxygen and other substances
Carried away

70
Q

The gas exchange takes place because capillary walls are only

A

One cell thick,
Narrow,
Single file!

71
Q

No cell in the body is more than

A

Three or four cells away from a capillary

72
Q

Capillaries lead to

A

Veins

73
Q

Blood in veins is not under as much pressure as blood in

A

Arteries is.

74
Q

What keep the blood from flowing backward?

A

Valves

75
Q

What helps blood move in the veins?

A

The contraction of skeletal muscles around the veins

76
Q

What is blood made of?

A

Plasma, platelets, and red and white blood cells.

77
Q

An adult human body has about

A

5 liters of blood. You might have less than that.

78
Q

The fluid part of the blood is called

A

Plasma

79
Q

Are tiny pieces of larger cells found in bone marrow. These only last for 5 to 10 days, but they have an important role.

A

Platelets

80
Q

Help keep you healthy by fighting pathogens such as bactéria and viruses.

A

White blood cells

81
Q

Some white blood cells squeeze out of blood vessels to search for
Other white blood cells form

A

Pathogens, when they find them they destroy it.

Antibodies

82
Q

Are chemicals that identify pathogens

A

Antibodies

83
Q

White blood cells also keep you healthy by

A

Destroying body cells that have died or been damaged.

Each red blood cell has

A

Hemoglobin

86
Q

Is an oxygen carrying protein, it clings to the oxygen molecules you inhale.

A

Hemoglobin

87
Q

What does cell need to carry out life functions?

A

Oxygen

88
Q

The disk shape of red blood cells helps them squeeze into

Capillaries

89
Q

How would the body be affected if red blood cells had low levels of hemoglobin?

A

Cells will have difficulties carrying out life functions

90
Q

Blood in veins is under less pressure than arterial blood because

A

Veins have larger internal diameters than arteries do. Veins carry larger volumes of blood more slowly.

91
Q

The circulation between the heart and the rest of the body is called

A

Systemic circulation

92
Q

Pulmonary circulation

93
Q

blood is pumped to the lungs where carbon dioxide leaves the blood and oxygen enters the blood

A

In pulmonary circulation

94
Q

Blood moves around the body

A

In systemic circulation

95
Q

Blood moves in two loops or circuits around the body

A

Pulmonary circulation, and systemic circulation

96
Q

What are some problems that affect the cardiovascular system?

A

Smoking, poor diet, stress, physical inactivity, heredity.

97
Q

Cardiovascular diseases

A

Atherosclerosis, hipertension, heart attacks.

98
Q

Is a hardening of artery walls caused by the build up of cholesterol and other lipids. The buildup causes to become narrower and less elastic, blood can’t flow easily. When an artery is blocked, oxygen cannot reach the heart and the person may have a heart attack.

A

Atherosclerosis

99
Q

Is abnormally high blood pressure. Atherosclerosis may be the cause in part for it. The higher the blood person the higher the risk for heart attack and strokes there is.
If not treated can also cause kidney damage and shorten life expectancy. Can be controlled with diet and sometimes with medicine

A

Hypertension

100
Q

Happens when an artery that supplies blood to the heart becomes clogged and the heart muscle tissue that depends on that’s blood supply does not get oxygen. If enough heart muscle cells get damaged, the heart may stop beating.

A

Heart attack

101
Q

Can happen when a blood vessel in the brain becomes blocked or bursts. That part of the brain receives no oxygen. Without oxygen the brain cells die. Brain damage that occurs during a stroke can affect many parts of the body. Can experience paralysis or difficulty in speaking.

A

Stroke

102
Q

The group of organs that takes in oxygen and get rid of carbon dioxide
