Answer 7

superior vena cava

Question 8

one of the 4 heart chambers
receives blood low in oxygen and empties blood into the right ventricle

Answer 8

right atrium

Question 9

pumps blood low in oxygen to the lungs

Answer 9

right ventricle

Question 10

one of the 4 chambers of the heart receives blood full of oxygen from the lungs and empties it into the left ventricle

Answer 10

left atrium

Question 11

pumps oxygen rich blood into the body

Answer 11

left ventricle

Question 12

carry blood from heart to lungs, only arteries that carry oxygen poor blood

Answer 12

pulmonary arteries

Question 13

blood vessels that transfer freshly oxygenated blood from lungs to left atrium of the heart

Answer 13

pulmonary veins

Question 14

main artery that carries blood away from the heart to the rest of the body

Answer 14

aorta

Question 15

heart valves

Answer 15

parts of the heart that act like doors. open and close to let blood flow from one area of the heart to another

Question 16

three heart valves

Answer 16

pulmonary
mirtal
aortic

Question 17

pulmonary valve

Answer 17

3 leaflets
allow blood to pump from right ventricle to pulmonary artery
prevents blood from going backward

Answer 18

Mitral
2 leaflets
blood from lungs to left atrium,
Aortic
3 leaflets left ventricle to aorta

Question 19

blood vessles

Answer 19

range of sizes and structures depending on role within the body
arteries, capillaries, veins

Question 20

arteries

Answer 20

distribute oxygen hormones and nutrients throughout body
muscular tube lined with smooth muscle

Question 21

capillaries

Answer 21

delicate blood vessels
transport blood nutrients and oxygen to cells in organs and body system

Question 22

veins

Answer 22

collect oxygen poor blood and return to heart

Question 23

illnesses and disease

Answer 23

high cholesterol
stroke
heart attack

Question 24

high cholesterol causes

Answer 25

lack of exercise, unhealth diet and drinking and smoking too much

Question 26

high cholesterol symptoms

Answer 26

decrease blood flow

eating health
being active
avoiding smoking and drinking
untreated plaque can build up and cause a heart attack of stroke

Question 28

what is a stroke

Answer 28

brain does not get enough blood, or blood vessel ruptures
blood vessel intruded by clot = ischemic
blood vessel ruptures, blood spill, and pressure on brain cells = hemorrhagic

Question 29

causes of a stroke

Answer 29

stress
high blood pressure

Question 30

stroke symptoms

Answer 30

blood flow gets limited and stops flowing to brain
lack of oxygen and nutrients in brain
brain cells instantly die

Question 31

stroke treatmemts

Answer 31

ischemic stroke thrombolytic drugs or mechanical thrombectomy to remove clot
hemorrhagic stoke surgery to prevent bleeding

Question 32

what is a heart attack

Answer 32

cut of of supply of blood and oxygen to the body
irreversible damage to muscle cells (after 30 mins)

Question 33

causes of heart attack

Answer 33

lack of exercise
stress
smoking

Question 34
