Cardiovascular

Question 1

Function of Circulatory System

Answer 1

Deliver O2 and nutrients around the body

Remove waste - CO2

Question 2

Main Components and Their Function

Answer 2

Blood - circulates O2, removes CO2
Heart - pumps blood
Blood vessels - form circuit to carry blood

Question 3

4 Components of Blood

Answer 3

Erythrocytes - transport O2, O2 binds to hemoglobin
Leukocytes - fight infection
Plasma - transport nutrients
Platelets - blood clotting

Question 4

Systemic System

Answer 4

Carries nutrients to cells and picks up waste

Question 5

Pulmonary System

Answer 5

Transports oxygen poor blood from right ventricle to lungs

Question 6

Coronary System

Answer 6

Supply blood to heart muscle

Question 7

Veins

Answer 7

Carry blood toward heart

Question 8

Arteries

Answer 8

Carry blood away from heart

Question 9

Capillaries

Answer 9

Absorb oxygen and nutrient into organs and tissues

Question 10

Coronary Arteries

Answer 10

Supply the heart with blood

Question 11

Aorta/Vena Cava

Answer 11

Aorta supplies blood to body

Vena Cava brings blood above and below

Question 12

Direction of Blood Flow

Answer 12

Superior vena cava receives deoxygenated blood from upper body
Inferior vena cava receives deoxygenated blood from lower body
Empty into RA, through tricuspid
RV - pulmonary valve
Pulmonary artery - lungs for gas exchange

Oxygenates Blood comes from lungs - pulmonary veins - LA
LA-mitral valve - LV
LV - aorta - body

Question 13

EKG Importance

Answer 13

Shows heart functions, give info on rhythm, atrial fibrillation, heart attack

Question 14

Ultrasound Importance

Answer 14

Diagnose pain, swelling, infection, assess functions inside the body

Question 15

Blood Pressure

Answer 15

Amount of force exerted against wall of arteries
Systolic - 100-140
Diastolic 60-90

Sphygmomanometer: bp test with tightening of arm cuff

Question 16

4 Vital Signs

Answer 16

Temp - 37°c
Pulse - 60-100bpm
Respiration - 12-16 breaths/minute
Blood Pressure - 120/80

Question 17

Autonomic Nervous System

Answer 17

Regulates heart rate

Question 18

Path of Impulse

Answer 18

Begins at sinoatrial node, through atria (contraction), Atrioventricular node, bundle of HIS, purkinje fibres (ventricle contract)

Question 19

Systole

Answer 19

Contractions of atrium and ventricle

Question 20

Diastole

Answer 20

Relaxation of atrium and ventricles

Question 21

Coronary Bypass

Answer 21

Done when plaque buildup.

Anesthesia, artery graft taken, sternum and rib cage open, blood rerouted in heart-lung bypass machine, medication to stop heart beating, graft attached to aorta or coronary artery

Question 22

Angioplasty

Answer 22

Plaque occurred,
Needle through femoral artery, guide wire advanced to heart, fluoroscope manages progress, catheter inserted, dye makes more viable, ballon inflated, then deflated and everything removed

Question 23

Stenting

Answer 23

Wire mesh tube, keep artery open, instead through balloon after angioplasty, locks in place to keep artery open

Question 24

DIPPS

Answer 24

Dignity,
Independence
Privacy 
Preferences 
Safety

Question 25

EKG

Answer 25

Takes picture of hearts electrical activity

Question 26

EKG Reading

Answer 26

Pwave- contraction of atrium
PQ segment - ventricles fill
QRS Complex - contraction of ventricle
ST segment - ventricles empty 
Twave - ventricle reset
