Study Notes

Cranial Vena Cava

Major vein that carries deoxygenated blood from the head, neck, and upper extremities to the right atrium of the heart.

Pulmonary Semilunar Valve

Located between the right ventricle and the pulmonary artery.
Prevents backflow of blood into the right ventricle after it has been pumped into the pulmonary circulation.

Right Atrium

Receives deoxygenated blood from the body via the superior and inferior vena cavae.
Pumps blood into the right ventricle through the right atrioventricular valve.

Right Atrioventricular Valve

Also known as the tricuspid valve.
Prevents backflow of blood into the right atrium when the right ventricle contracts.

Right Ventricle

Receives deoxygenated blood from the right atrium.
Pumps blood to the lungs through the pulmonary arteries for oxygenation.

Caudal Vena Cava

Major vein that carries deoxygenated blood from the lower body to the right atrium.
Also known as the inferior vena cava.

Arch of Aorta

Curved segment of the aorta that distributes oxygenated blood to the upper body.
Branches off into major arteries supplying the head, neck, and arms.

Left Atrium

Receives oxygenated blood from the lungs via the pulmonary veins.
Pumps blood into the left ventricle through the left atrioventricular valve.

Aortic Semilunar Valve

Located between the left ventricle and the aorta.
Prevents backflow of blood into the left ventricle after blood is ejected into the aorta.

Left Ventricle

Receives oxygenated blood from the left atrium.
Pumps blood into the aorta to supply systemic circulation.

Septum

Muscular wall dividing the right and left sides of the heart.
Prevents mixing of oxygenated and deoxygenated blood.

Aorta

Largest artery in the body, carrying oxygenated blood from the left ventricle to the rest of the body.
Major branches supply blood to various organs and tissues.

Description

Test your knowledge of the circulatory system by labeling key components of the heart and its major vessels. This quiz covers important structures such as the cranial vena cava, pulmonary semilunar valve, and more. Enhance your understanding of how blood flows through these vital structures.
