Heart Anatomy and Circulation

A collection of vocabulary flashcards covering the anatomical structures, chambers, valves, and vessels of the heart and its circulatory pathways.

Aorta

The primary systemic artery that receives oxygenated blood from the left ventricle (Vänster kammare) through the aortic valve (Aortaklaffen) and routes it to the body.

Lungartären

The pulmonary artery; the blood vessel that carries deoxygenated blood from the right ventricle (Hoger kammare) through the pulmonary valve (Pulmonalisklaffen) to the lungs.

Lungvenen

The pulmonary vein; the blood vessels that return oxygen-rich blood from the lungs into the left atrium (Vänster formak).

Höger förmak

The right atrium; the upper heart chamber that receives deoxygenated blood returning from systemic circulation via the superior vena cava (Övre halvenen) and inferior vena cava (Undre halvenen).

Vänster formak

The left atrium (Vänster förmak); the upper heart chamber that collects oxygenated blood from the pulmonary veins (Lungvenen) and directs it toward the left ventricle (Vänster kammare).

Hoger kammare

The right ventricle (Höger kammare); the lower chamber that receives deoxygenated blood from the right atrium (Höger förmak) via the tricuspid valve and pumps it out through the pulmonary artery (Lungartären).

Vänster kammare

The left ventricle; the muscular lower chamber that receives oxygenated blood from the left atrium (Vänster formak) and pumps it through the aortic valve (Aortaklaffen) into the aorta.

Övre halvenen

The superior vena cava (Övre hålvenen); the large vein carrying deoxygenated blood from the upper half of the body downward into the right atrium (Höger förmak).

Undre halvenen

The inferior vena cava (Undre hålvenen); the large vein carrying deoxygenated blood from the lower part of the body upward into the right atrium (Höger förmak).

Tricuspidalisklaffen

The tricuspid valve; the atrioventricular valve located between the right atrium (Höger förmak) and the right ventricle (Hoger kammare) that prevents backflow of blood into the atrium.

Pulmonalisklaffen

The pulmonary valve; the semilunar valve situated between the right ventricle (Hoger kammare) and the pulmonary artery (Lungartären) that prevents blood from flowing backward into the ventricle.

Mitralisklaffen

The mitral valve (bicuspid valve); the atrioventricular valve positioned between the left atrium (Vänster formak) and the left ventricle (Vänster kammare) that controls unidirectional blood flow.

Aortaklaffen

The aortic valve; the semilunar valve located between the left ventricle (Vänster kammare) and the entrance to the aorta that prevents backward flow of pumped blood into the ventricle.

Hjärtsäck

The pericardium; the protective sac or membrane surrounding and enclosing the entire heart structure and the roots of the major vessels.
