femoral vein

brings blood from upper leg (thigh) back to common illiac vein (major vein of leg)

femoral artery

brings blood to femoral region, moves down leg (major artery of leg)

inferior vena cava

brings blood to heart from all body parts inferior to heart

superior vena cava

brings blood to heart from veins superior to heart

Atherosclerosis (specific)

build up of plaque (cholesterol/fats) on artery walls, obstructing blood flow

veins

carry deoxygenated blood to the heart

arteries

carry oxygenated blood away from the heart

systemic circulation

circulation that supplies blood to body, returns blood back to heart

medial cubital vein

connects the cephalic and basilic veins

factors that decrease cardiac output

constricting vessels, healthy heart

peripheral artery disease symptoms

cramping, numbness, tingling

factors that increase cardiac output

exercise, strong emotion, caffeine, heart rate

True or False: Pulmonary veins take unoxygenated blood away from the heart.

false

pulmonary circulation

flow of blood from the heart to the lungs and back to the heart

arteriosclerosis (general)

hardening of the arteries

if CO goes up

heart rate goes up

Cardiac output equation

heart rate x stroke volume

basilic vein

inner arm, bring blood from arm to subclavian

The most muscular chamber of the heart is the __________.

left ventricle

Pulse (heart rate)

# of times heart beats (contracts) every minute

common Illiac artery

branches off descending aorta arch to bring blood to each leg

subclavian vein

bring blood back from arms

internal jugular vein

brings blood back from head/neck

common illiac vein

brings blood from each leg back to inferior vena cava

dorsal venous network

brings blood from hand towards arm

descending aorta

brings blood from heart to all parts of body inferior to heart

ascending aorta

brings blood from heart to parts of body superior to heart

posterior tibial vein

brings blood from lower leg up towards femur

renal vein

brings blood from the kidneys to the inferior vena cava

veins have what

valves

cause of varicose veins

valves not working

heart conduction/steps of heart beat

1. SA node fires 2. Atria contract 3. AV node fires 4. signal travels to AV bundle 5. Signal travels to bundle branches 6. Signal travels to perkinje fibers 7. Ventricles contract

Heart blood flow order

Blood flows in the following sequence in the heart: Superior vena cava/Inferior vena cava, right atrium, tricuspid valve, right ventricle, pulmonic valve, pulmonary artery, lungs, pulmonary veins, left atrium, bicuspid valve, left ventricle, aortic valve, aorta

diastolic blood pressure

Pressure in the arteries when the heart relaxes and ventricles fill with blood (in between beats)

On the right side of the heart, blood flows from the right ventricle to the?

Pulmonic valve to the pulmonary artery

natural pacemaker of the heart

SA node

ulnar artery

blood down medial forearm to hand

radial artery

blood down to lateral arm to hand

what is the medial cubital vein used for

blood draws/IV

digital arteries

blood flow to fingers

superficial palmer arch

blood from wrist down to fingers

varicose veins

abnormally swollen and twisted veins, usually occurring in the legs

capillaries are the walls of

alveoli, allow diffusion

Cardiac Output (CO)

amount of blood pumped out by both ventricles per minute

stroke volume

amount of blood pumped out of heart every heart beat

ABI

ankle brachial index

What part of the heart delivers richly oxygenated blood to the body?

aorta

subclavian artery

blood to arm

carotid artery

blood to brain, neck, head

renal artery

blood to kidney

brachial artery

blood to lower arm

popliteal artery

back of knee, bring blood to lower leg

heart rate unit

beat/min

peripheral artery disease

blockage of arteries

stroke volume unit

mL/beat

cardiac output unit

mL/min or L/min

why is the interventricular septum important

make sure oxygenated/deoxygenated blood don't mix

systolic blood pressure

measures force heart exerts on artery walls each time it beats

posterior tibial artery

medial portion of leg, blood to lower leg and feet

Why is the left ventricle thicker than the right?

must pump blood to entire body

valves

prevent back flow of blood

What part of the heart delivers unoxygenated blood to the lungs?

pulmonary artery

What part of the heart delivers oxygenated blood to the heart?

pulmonary vein

The blood enters on the left side of the heart through the ______________ and enters the left atrium. It then passes through the _____________to enter the left ventricle.

pulmonary vein, bicuspid valve

What is the interventricular septum?

separates ventricles

two main factors that affect cardiac output

stroke volume, heart rate

Capillaries function

supply blood to tissue, exchange gas

coronary arteries

supply oxygenated blood to the heart

Arteries structure

thick walls, high blood pressure

veins structure

thin walls, lower blood pressure
