Answer 6

in bone marrow

Question 7

produces cellular components of blood

Question 8

Answer 8

Red Blood Cells

Question 9

functions in the Immune system, attack invading organisms, and removes toxins, waste, and damaged cells

Answer 9

White Blood Cells

Question 10

membrane-bound fragments of larger cells that works to prevent blood loss

Answer 10

Platelets

Question 11

stops the flow of blood out of damaged blood vessels

Answer 11

blood clotting

Question 12

what happens after an injury?

Answer 12

the muscles in the damaged blood vessel contract which restricts the blood flow, the platelets attach to the vessel breaches and form a plug to help restrict the blood flow, and then the damaged tissue releases chemical signals that begin the blood clotting process

Answer 13

Fibrin

Question 14

consist of a net made of Fibrin which forms a patch over the damaged area

Answer 14

blood clot

Question 15

what happens when you get a blood clot?

Answer 15

Cell devision occurs around the tissue and damaged vessel, the cut is sealed and the patch dissolves when healed

fist sized organ that consists of two coordinated muscular pumps

Answer 16

the heart

Question 17

in the heart, what does the pump on the right side do?

Answer 17

receives oxygen-poop blood from the body and sends it to the lungs

Question 18

in the heart, what does the pump on the left side do?

Answer 18

recovers oxygen-rich blood from the lungs and circulates it within the body

Question 19

what are the two chambers int he heart?

Answer 19

the Atrium(thin) and the ventricle(thick)

Question 20

small patch of muscle tissue in the right atrium wall that determines intrinsic heart rhythm by sending out electrical signals and controlling the heart rate

Answer 20

Sinoatrial (SA) node

Question 21

what is the cardiac cycle?

Answer 21

a complete sequence of the heart filling with blood and then pumping

Question 22

what are the two phases of the cardiac cycle?

Answer 22

the Systole(contraction) phase and the Diastole(relaxed)phase
