Answer 1

Lower edge

Question 2

Auscultation of heart. Where

Answer 2

Over the apex left mid clavicle between 5 and 6

Question 3

Each chamber of heart has what type of tissue

Answer 3

Cardiac muscle tissue aka myocardium

Question 4

Each chamber of heart lined with/ what tissue

Answer 4

Smooth tissue called endocardium

Question 5

Valves of the heart

Answer 5

AV=tricuspid/mitrial
SV=semi lunar/ aortic

Question 6

Size of heart

Answer 6

Triangular/fist

Question 7

Location of heart

Answer 7

Inside mediasternum between sternum and vertabrae

Question 8

What empties into right atrium

Answer 8

Oxygen poor blood

Question 9

What flows into left atrium

Answer 9

Oxygen rich blood (from lungs)

Question 10

Is the heart hollow

Answer 10

Yes

Question 11

Atrium /ventricles largest?

Answer 11

Ventricles

Question 12

Atrium/ ventricle thicker wall?

Answer 12

Ventricles

Question 13

What happens during S1 Lub

Answer 13

AV closing/ventricles contracting. Beginning of systole

Question 14

What happens during S2 Dub

Answer 14

SV closing/ventricle relaxing/ distole

Question 15

Atrial systole

Answer 15

Atrium contracts and ventricles fill w/ blood

Question 16

Pulmonary circulation

Answer 16

Blood flow from right ventricle to to lungs and back

Question 17

Systemic circulation

Answer 17

Flow of blood from left ventricle thru out body and back

Question 18

Coronary circulation

Answer 18

Coronary arteries make nutrient rich deliveries via coronary artery via first branch off aorta

Question 19

Coronary bypass

Answer 19

Severely restricted coronary artery blood flow arteries from other part of body used because blockage prevents O2 and nutrients from getting to the muscle itself

Question 20

SA node / sinotrial node (electrical conduction)

Answer 20

Pacemaker located at top of right atrium makes atria contract and stimulates tricuspid valve

Question 21

AV node/ atrioventricular node (electrical conduction)

Answer 21

Is at lower part of right atrium makes ventricles contract

Question 22

If SA and SV nodes fail

Answer 22

Pacemaker or defibrillator may be needed

Question 23

Tunica external

Answer 23

Outer layer of blood vessel has connective tissues

Question 24

Tunica media

Answer 24

Maintains blood pressure middle layer of blood vessel It contains smooth muscle

Question 25

Tunica intima

Answer 25

Inner layer of blood vessel contains endothelial tissue

Question 26

Arteries are thicker than veins

Answer 26

Under more pressure except for pulmonary artery

Question 27

What are pulse points

Answer 27

Expansion and recoil of the artery walls

Question 28

Which vessels take blood away from heart

Answer 28

Arteries From the heart to arterioles and capillaries

Question 29

Which vessel takes blood to the heart

Answer 29

Veins carry blood to the heart away from capillaries low pressure. Except for pulmonary vein

Question 30

Capillaries

Answer 30

Deliver O2 and nutrients and fluids to tissues. They are vessels of exchange. Take away CO2 and waste

Question 31

Factors affecting blood pressure

Answer 31

Venous return, a strong heart, adequate arterial pressure, valves in veins, pumping action of contracting skeletmuscle, changing pressures in chest cavity (breathing)

Question 32

Principle veins of the body

Answer 32

Superior and inferior vena cava, R and L subclavian, pulmonary vein, hepatic portal, femoral, jugular

Question 33

Coronary arteries

Answer 33

Supply blood to the heart

Question 34

Principal arteries the body

Answer 34

Aorta, pulmonary artery, coronary arteries, subclavian arteries, renal arteries
