3.1 Heart Stuff

Question 1

Artery characteristics

Answer 1

-thick walls
-pump blood directly out of heart
-no valves
-has outer elastin

Question 2

Vein characteristics

Answer 2

-only has inner elastin
-weaker walls
-pumps deoxygenated blood into heart
-has valves

Question 3

Coronary arteries

Answer 3

The arteries that supply oxygenated blood to the heart

Question 4

Types of coronary arteries

Answer 4

-left coronary artery (supplies to left side)
-left interior descending artery (supplies to front and left side)
-circumflex artery (supplies outer side and back)
-right coronary artery (supplies to nodes, and right chambers

Question 5

Capillary function

Answer 5

The blood vessels that connect your arteries and veins, where oxygen is exchanged for oxygen

Question 6

Coratid artery vs jugular vein

Answer 6

Carotid supplies blood to the head
Veins takes deoxygenated blood back to heart

Question 7

Areas where you have/major arteries (upper body)

Answer 7

-subclavian (collar bone)
-axillary (shoulder)
-brachial (upper arm)
-radial (lower arm, thumb side)
-ulnar (lower arm, pinky side)

Question 8

Areas where you have/major lower body arteries

Answer 8

-descending aorta (back)
-iliac artery (pelvis)
-femoral artery (femoral)
-popliteal artery (knee)
-dorsal pedis (foot)

Question 9

Areas where you have/major upper body veins

Answer 9

-superior vena cava (coming out the heart)
-jugular vein (neck)
-subclavian vein (collar bone)
-axillary vein (upper arm-ish)
-cephalic vein (radial/thumb side)
-basilic vein (ulnar/pinky side)

Question 10

Areas where you have/major lower body veins

Answer 10

-inferior vena cava (coming out the heart)
-iliac vein(hip)
-femoral vein
-popliteal vein (knee)
-dorsal pedis (foot)

Question 11

What is varicose vein?

Answer 11

The enlarging/bulging of a vein. Can be caused by increased blood pressure or damage to blood vessels/valves (causing build up) arteries can’t get varicose because they don’t have valves

Question 12

Systolic vs diastolic

Answer 12

S/D
Systole, heart contracts
Diastole, hearts at rest

Question 13

What’s a normal blood pressure

Answer 13

120/80 (something close to that range)

Question 14

Stroke volume

Answer 14

The amount of blood being pumped through your heart

Question 15

Cardiac output

Answer 15

A measure of how much blood is being pumped by both ventricles in one minute

Question 16

Cardiac output formula

Answer 16

Cardiac output (mL/min) = heart rate (b/min) x stroke volume (mL/b)

Question 17

Hypo vs hyper

Answer 17

Hypo = under
Hyper = high/over

Question 18

Abi (ankle-brachial index)

Answer 18

Found by taking systolic of brachial vein divided (/) by the systolic of an ankle or pedis vein

Question 19

Normal ABI

Answer 19

Between 0.9 to 1.5

Question 20

what is PAD?

Answer 20

Loss of blood/blood flow in extremities (legs/arm) caused by a plaque build up, can lead to clotting

Question 21

What is bradycardia ?

Answer 21

A slow heart rate caused by possible underlying conditions, causes less oxygen to get to organs,can lead to serious issues.

Question 22

Arrhythmia

Answer 22

A problem with heart rate or heart rhythm

Question 23

Pulmonary loop

Answer 23

Right side of the heart picks up deoxygenated blood and takes it to the lungs

Question 24

Systemic loop

Answer 24

Left side of heart moves the blood to throughout the body

Question 25

Pulmonary circulation

Answer 25

The system of transportation that moves the de oxygenated blood from heart to lung

Question 26

Systemic circulation

Answer 26

moves blood between heart to rest of body
