pulmonary trunk

what part of the heart is this? carries blood from right ventricle to pulmonary arteries

aorta

what part of the heart is this? Largest artery in the body

aortic arch

what part of the heart is this? a curved blood vessel from which arteries branch to the head and neck.

ascending aorta

what part of the heart is this? Branches off the left ventricle; carries oxygen rich blood to parts of the body above the heart

descending aorta

right coronary arteries

what part of the heart is this labeled 4? right marginal artery and posterior interventricular artery

left coronary arteries

what part of the heart is this labeled one? Anterior interventricular artery and circumflex artery. Supplies blood to the left ventricle, left atrium, and interventricular septum

coronary sinus

what part of the heart is this? enlarged vessel on the posterior aspect of the heart that empties blood into the right atrium

ligamentum arteriosis

what part of the heart is this? connects the inferior surface of arch to the left pulmonary artery

ductus arteriosis

what part of the heart is this? Blood vessel in fetuses; attaches pulmonary artery to aorta; closes shortly after birth

foramen ovale

what part of the heart is this? connects the two atria in the fetal heart

interventricular septum

what part of the heart is this? separates ventricles

chordae tendineae

what part of the heart is this? thin bands of fibrous tissue that attach to the valves in the heart and prevent them from inverting

trabeculae carneae

what part of the heart is this? muscular ridges on the internal surface of the ventricles

papillary muscles

what part of the heart is this? responsible for pulling the atrioventricular valves closed by means of the chordae tendineae

pectinate muscles

what part of the heart is this? internal ridges of myocardium in right atrium and both auricles

SA node (sinoatrial node)

what part of the heart is this? sensitive tissue in the right atrium wall that begins the heartbeat

AV node (atrioventricular node)

what part of the heart is this? region of the heart between the right atrium and right ventricle from which electrical impulses spread to the ventricles during a heartbeat

AV node bundles (His)

what part of the heart is this? a collection of heart muscles

right/left bundle branches of heart

what part of the heart is this?

Purkinje fibers

what part of the heart is this? fibers in the ventricles that transmit impulses to the right and left ventricles, causing them to contract

it starts at the inferior and superior vena cava

where is the begging of the blood flow in the heart?

deoxygenated blood

When the blood goes through the inferior/superior vena cava, is the blood oxygenated or deoxygenated?

it then goes to the right atrium. the blood is deoxygenated.

from the inferior and superior vena cava, where does the blood go next? and is it oxygenated or deoxygenated?

the blood goes through the tricuspid valve. the blood is deoxygenated.

from the right atrium, what does the blood flow there to get to the next place? and is this blood oxygenated or deoxygenated?

it goes to the right ventricle. the blood is deoxygenated.

After going through the tricuspid valve, where does the blood go next? and is this blood oxygenated or deoxygenated?

the blood goes through the pulmonary semilunar valve. the blood is deoxygenated.

When the blood is in the right ventricle, what does it go through to get to the next place? and is this blood oxygenated or deoxygenated?

the blood goes to the pulmonary trunk. the blood is deoxygenated.

once the blood goes through the pulmonary semilunar valve, where does it go next? and is this blood oxygenated or deoxygenated?

the blood goes to the right and left pulmonary arteries. the blood is deoxygenated.

from the pulmonary trunk, where does the blood go next? and is this blood oxygenated or deoxygenated?

the blood flows to the lungs (pulmonary circulation). the blood is a mix of oxygenated and deoxygenated blood.

from the right and left pulmonary arteries, where does the blood flow next? and is this blood oxygenated or deoxygenated?

the blood goes to the right and left pulmonary veins. the blood is oxygenated.

from the lungs, where does the blood flow next? and is this blood oxygenated or deoxygenated?

the blood flows to the left atria. the blood is oxygenated.

from the right and left pulmonary veins, where does the blood flow next? and is this blood oxygenated or deoxygenated?

the blood flows through the bicuspid valve. the blood is oxygenated.

from the left atria, what does the blow flow through to get to the next place? and is this blood oxygenated or deoxygenated?

it goes to the left ventricle. the blood is oxygenated.

after going through the bicuspid valve, where does the blood flow to next? and is this blood oxygenated or deoxygenated?

the blood goes through the aortic semilunar valve. the blood is oxygenated.

once in the left ventricle, what does the blood go through to get to the next place? and is this blood oxygenated or deoxygenated?

the blood goes to the aorta. the blood is oxygenated.

once through the aortic semilunar valve, where does the blood go next? and is this blood oxygenated or deoxygenated?

the blood goes to all body tissues (systemic circulation). the blood is a mix of deoxygenated and oxygenated blood.

after going through the aorta, where does the blood go next? and is this blood oxygenated or deoxygenated?
