Question 1

What are RBCs

Answer 1

Carry oxygen from lungs to cells, tissues and organs. They remove CO^2.

Question 2

What are WBCs

Answer 2

Defend your body against infection and disease.

Question 3

Blood platelets

Answer 3

Cell fragments to help blood clot

Question 4

Blood cells other name

Answer 4

Solid component named formed elements

Question 5

Plasma cells other name

Answer 5

Liquid component

Question 6

What do blood cells consist of?

Answer 6

RBCs, WBCs and platelets

Question 7

What are plasma cells made up of?

Answer 7

They make up more than half of your blood

Question 8

What are the three groups of blood cells?

Answer 8

Erythrocytes, RBCs, leukocytes, WBCs and thrombocytes, blood platelets.

Question 9

Where are blood cells produced?

Answer 9

In the bone marrow, during formation proteins in the bloodstream and bone marrow help change their size and shape according to their functions

Question 10

Blast

Answer 10

A blood cells starts out as this large immature cell, and it shrinks as it matures

Question 11

Hemoglobin

Answer 11

Is a protein. As the red blood cells matures, hemoglobin replaces its nucleus, and it allows RBCs to transport oxygen and CO^2 throughout the blood.

Question 12

Antigens meaning

Answer 12

Surface of RBCs, are naturally occurring. These help determine a person’s blood type.

Question 13

Four major inherited blood types?

Answer 13

A, B, AB, O

Question 14

What if someone has RBC’s with a B or AB blood type?

Answer 14

They have a and/or B antigens

Question 15

Red blood cells of someone with an O blood type?

Answer 15

Do not contain antigens

Question 16

What does it mean if a person has Rh antigen?

Answer 16

The person has a positive blood type. Lack of Rh antigen leads to a negative blood type.

Question 17

Leukocytes main function

Answer 17

Essential role in the immune system

Question 18

What are thrombocytes

Answer 18

Aid in blood clotting. Platelets rush to injured area and begin to stick together to trap cells from escaping the tissue wall.

Question 19

What are megakaryocytes

Answer 19

Thrombocytes, bone marrow cells with very large nuclei.

Question 20

Hemostasis meaning

Answer 20

Slow down the flow of blood until other clotting factors come into play

Question 21

Plasma cells contain?

Answer 21

Liquid portion of blood that contains water, hormones, sugar, salts and waste.

Question 22

Proteins in plasma?

Answer 22

Albumin, globulin, fibrinogen and prothrombin

Question 23

primary function of cardiovascular system

Answer 23

Circulates oxygen rich blood throughout the body and removes CO^2.

Question 24

What do the blood vessels do?

Answer 24

Form a closed loop of tubes and carry blood from the heart to the rest of the body and back to the heart.

Question 25

3 types of blood vessels?

Answer 25

Arteries, veins and capillaries

Question 26

What do capillaries do and what does it look like?

Answer 26

Move blood away from the heart, because of contraction the walls of an artery are thick, strong and elastic

Question 27

what happens as arteries get away from the heart

Answer 27

Get smaller and smaller and branch into all areas of the body

Question 28

Arterioles meaning

Answer 28

Smaller arteries that connect to capillaries

Question 29

What are capillaries

Answer 29

Small so that RBCs can pass through them one at a time. In these capillaries, oxygen and CO^2 are exchanged.

Question 30

What happens right after the O and Co^2 exchange in the capillaries?

Answer 30

RBCs pass through venules and head towards the heart.

Question 31

What do veins do and look like?

Answer 31

Carry blood toward the heart through one way valves that direct the flow of blood, the walls of a vein and thinner and less elastic. Surrounding muscle tissues also contract to help veins force blood toward the heart.

Question 32

what happens as veins get closer to the heart

Answer 32

they get bigger
