Science Quiz Chpt 17 Section 3 & 4

Front 1

Plasma

Back 1

The liquid part of blood. About 55% of the blood is plasma. Made up of 90% water and 10% dissolved materials, including glucose.

Front 2

They yellow color in plasma is due to what?

Back 2

protein content

Front 3

Red Blood cells

Back 3

take up oxygen in the lungs and deliver it to cells. made up mostly of hemoglobin. disk like, flexible cells. Do not contain a nucleus

Front 4

Where are red blood cells produced?

Back 4

in the bone marrow

Front 5

hemoglobin

Back 5

iron containing protein that chemically binds to oxygen

Front 6

white blood cells

Back 6

the body's disease fighters. some alert the body to foreign invaders, some produce chemicals to fight invaders, others surround and kill the invaders

Front 7

platelets

Back 7

cell fragments that produce fibrin for blood clotting

Front 8

fibrin

Back 8

a protein produced by platelets that act as a net catching red blood cells to clot them and stop blood flow

Front 9

blood transfusion

Back 9

transference of blood from 1 person to another

Front 10

marker molecules

Back 10

determine the blood type and type of blood that can be safely recieved in a transfusion. Red blood cells with foreign marker molecules are affected by proteins found in the plasma that causes the cells with "foreign" markers to clump together

Front 11

safe transfusions

Back 11

blood that does not contain red blood cells with marker molecules that your body sees as foreign.

Front 12

cross-matching

Back 12

when your blood type is checked against blood that was donated to ensure that it is compatible before a transfusion.

Front 13

Blood Type A can safely recieve

Back 13

Blood types A and O

Front 14

Blood Type B can safely recieve

Back 14

Blood types B and O

Front 15

Blood Type AB can safely recieve

Back 15

Blood types A, B, AB, and O

Front 16

Blood Type O can safely recieve

Back 16

Blood type O

Front 17

lymph

Back 17

liquid that leaks out across the capillaries. It is called lympy when it enters the lympathic system. made up of water and dissolved materials (like glucose), this fluid carries the materials that cells and tissues need.

Front 18

lymph nodes

Back 18

small knobs of tissue that act as filters for the lymph

Front 19

When do lympy nodes enlarge?

Back 19

When the body is fighting an infections

Front 20

atherosclerosis

Back 20

the thickening of the artery wall due to the build up of fatty materials (like cholesterol). Especially bad when it occurs in the coronary arteries

Front 21

heart attack

Back 21

occurs when the blood to the heart or part of the heart is blocked adn the heart does not receive the oxygen it needs. cells in the heart can die, this permanently damages the heart

Front 22

hypertension

Back 22

high blood pressure - consistently higher than 140/90. Is not always related to atherosclerosis, but often occur together

Front 23

3 ways to keep the cardiovascular system healthy

Back 23

exercise, balanced diet, avoid smoking

Front 24

How does exercise help your heart?

Back 24

strengthens the heart muscle and helps to prevent atherosclerosis

Front 25

How does a balanced diet help your heart?

Back 25

a diet low in fat and low in cholesterol can help to prevent the fatty buildup on arterial walls. Also reduce sodium to help prevent hypertension

Front 26

How does smoking damage your heart?

Back 26

smoking causes damage to the lungs, the heart and the blood vessels
