(36 cards)

Tricuspid Valve

Front

Valve of the heart located between the right atrium and the right ventricle. (1)

Back

Chordae Tendineae

Front

Tendons found within ventricles that prevent mitral and tricuspid valves from inverting. They are anchored by papillary muscles. (2)

Back

Inferior Vena Cava

Front

Large vein that drains deoxygenated blood from the thoracic, abdominal, pelvic, and lower extremity regions into the right atrium. (4)

Back

Ligamentum Arteriosum

Front

This structure replaces the ductus arteriosus in an adult heart. (1)

Back

Left Ventricle

Front

Chamber of the heart that receives oxygenated blood from the left atrium. Responsible for pumping oxygenated blood to the body through the aorta. (7)

Back

Pulmonary Trunk (Arteries)

Front

Artery that carries blood from the right ventricle to the lungs. This is the only artery in the body that contains deoxygenated blood. (1)

Back

Mitral Valve

Front

Valve of the heart located between the left atrium and the left ventricle. (4)

Back

Left Atrium

Front

Chamber responsible for receiving oxygenated blood from the lungs through the pulmonary veins. (11)

Back

Aortic Valve

Front

Valve within the heart located between the left ventricle and the aorta. (3)

Back

Papillary Muscles

Front

Muscles found within ventricles that anchor chordae tendonae. (1)

Back

Myocardium

Front

Muscular lining of the heart which contracts and sends blood on to it's next destination. (9)

Back

Right Ventricle, Internal View

Front

#12

Back

Semilunar Valve

Front

Valves of the heart located between the ventricles and the arteries they lead to. (2 & 3)

Back

Interatrial Septum

Front

Wall separating the right atrium from the left atrium. This is important so that deoxygenated blood does not mix with oxygenated blood. (4)

Back

Right Ventricle

Front

Chamber of heart responsible for pumping deoxygenated blood to the lungs. It receives deoxygenated blood from the right atrium. (8)

Back

Foramen Ovale

Front

Hole located within interatrial septum that allows blood to bypass lungs by going directly from the right atrium to the left atrium in a fetal heart.

Back

Superior Vena Cava

Front

Large vein that drains deoxygenated blood from head, neck, and upper extremity regions into the right atrium. (3)

Back

Pectinate Muscles

Front

Muscles located in atria that contract and send blood to their respective ventricles.

Back

Atrioventricular Valves

Front

Valves of the heart located between the atria and ventricles. (1 & 4)

Back

Coronary Arteries

Front

Blood vessels that feed the heart muscle cells (cardiocytes) (9)

Back

Endocardium

Front

Inner lining of the heart that consists of epithelial cells and comes into contact with the blood on the inside of the heart. (8)

Back

Trabeculae Carnea

Front

Muscles located in the ventricles which contract and send blood to their respective arteries.

Back

Oxygenated Blood

Front

Blood with a high oxygen content. Found within the left side of the heart. This blood is bright red.

Back

Aorta

Front

Artery that carries oxygenated blood from the left ventricle to the rest of the body. (2)

Back

Fossa Ovalis

Front

Basically, the scar that is left behind from the foramen ovale. This structure usually forms within 48 hours of birth.

Back

Coronary Sinus

Front

Vein on the posterior portion of the heart that drains deoxygenated blood from coronary veins and releases it into the right atrium.

Back

Right Atrium, Internal View

Front

#6

Back

Left Ventricle, Internal View

Front

#13

Back

Interventricular Septum

Front

Wall that separates the right ventricle from the left ventricle. This is important so that dexoygenated blood does not mix with oxygenated blood. (5)

Back

Right Atrium

Front

Chamber of heart that receives deoxygenated blood from the superior and inferior vena cava. This chamber pumps blood to the right ventricle. (6)

Back

Epicardium

Front

Outermost lining of the heart that forms a part of the pericardium. (10)

Back

Ductus Arteriosus

Front

Fetuses bypassed their lungs by using this structure. It takes blood from the pulmonary artery to the aorta. (1)

Back

Pulmonary Valve

Front

Valve within heart located between the right ventricle and the pulmonary trunk (artery). (2)

Back

Left Atrium, Internal View

Front

#11

Back

Deoxygenated Blood

Front

Blood that has a low oxygen content. Found within the right side of the heart. This blood has a burgundy color to it.

Back

Pulmonary Veins

Front

Vein that carries blood from the lungs to the left atrium. This is the only vein in the body that contains oxygenated blood. (5)
