Heart Anatomy

bicuspid valve

A valve in the heart that guards the opening between the left atrium and the left ventricle that prevents the blood in the ventricle from returning to the atrium.

tricuspid valve

controls the opening between the right atrium and the right ventricle

right ventricle

Pumps blood to the lungs

right atrium

Receives deoxygenated blood from the body

mitral insufficiency

Regurgitation of blood through the left AV valve is called

myocardium

Thick middle muscle layer of the heart

interventricular sulcus

grooves with blood vessels along septum between ventricles

right auricle

in right atrium, small ear shaped extension that increases volume

interatrial septum

separates the two atria

left ventricle

the chamber of the heart that receives arterial blood from the left atrium and pumps it into the aorta

epicardium

the external layer of the heart and the inner layer of the pericardium

left atrium

Chamber that receives oxygenated blood from the pulmonary veins and pumps it into systemic circulation.

pericardial cavity

F - fluid-filled cavity between the pericardial layers

trabeculae carnae

Irregular ridges and folds in the internal walls of the ventricles are known as the _________________.

left auricle

Located on the anterior surface of the left atrium and allows it to receive extra blood

interventricular septum

Partition that separates the right and left ventricles.

aortic valve

The semilunar valve separating the aorta from the left ventricle that prevents blood from flowing back into the left ventricle.

chordae tendineae

When the papillary muscles contract, the ______________ tighten, preventing blood from regurgitating from the ventricles to the atria

heart murmur

an abnormal sound from the heart produced by defects in the chambers or valves

pericarditis

an inflammation of the pericardium that causes an accumulation of fluid within the pericardial sac

visceral pericardium

another word for the epicardium

endocarditis

inflammation of the inner lining of the heart

endocardium

inner lining of the heart

parietal pericardium

outermost layer of the heart - G

papillary muscles

pull on AV valves via the chordae tendineae

pulmonary valve

valve positioned between the right ventricle and the pulmonary artery
