Heart Anatomy and Function Concepts

The video explains the internal structure of the heart, highlighting its four chambers: the atria and ventricles. It describes the function of the right atrium and ventricle in handling deoxygenated blood, and the left atrium and ventricle in managing oxygenated blood. The video also covers the role of the tricuspid and bicuspid valves in preventing backflow, and the semilunar valves. Additionally, it discusses the septum's role in separating oxygenated and deoxygenated blood.

What are the upper chambers of the heart called?

• Ventricles

• Valves

• Atria

• Septum

Why are the walls of the ventricles thicker than those of the atria?

• To support the heart valves

• To store more blood

• To pump blood to the lungs and body

• To separate oxygenated and deoxygenated blood

What is the function of the tricuspid valve?

• To separate the left and right sides of the heart

• To allow blood flow from the left atrium to the left ventricle

• To pump blood to the lungs

• To prevent backflow of blood from the right ventricle to the right atrium

Through which vessels does the right ventricle send blood to the lungs?

• Coronary arteries

• Pulmonary arteries

• Pulmonary veins

• Aorta

Which chamber receives oxygenated blood from the lungs?

• Right ventricle

• Left ventricle

• Left atrium

• Right atrium

What is another name for the bicuspid valve?

• Aortic valve

• Semilunar valve

• Mitral valve

• Tricuspid valve

What is the primary function of the heart tendons?

• To pump blood

• To support the heart valves

• To separate the heart chambers

• To transport oxygen

What is the role of the semilunar valves?

• To prevent backflow into the ventricles

• To store oxygenated blood

• To separate the atria

• To pump blood to the body

What is the function of the septum in the heart?

• To separate oxygenated and deoxygenated blood

• To pump blood to the lungs

• To store deoxygenated blood

• To support the heart valves

Which side of the heart deals with deoxygenated blood?

• Left side

• Right side

• Both sides

• Neither side
