Heart Anatomy

The video tutorial explains the anatomy of the heart, focusing on the serous membranes surrounding it, the structure and function of heart chambers, and the flow of blood through the heart. It also covers the orientation of the heart in the body and the cardiac cycle, detailing how blood circulates through the heart and lungs, and back to the body.

What is the primary function of the fibrous pericardium?

• To exchange gases

• To prevent heart overfilling

• To pump blood

• To produce hormones

Which chamber of the heart receives deoxygenated blood from the body?

• Right ventricle

• Left atrium

• Right atrium

• Left ventricle

Through which valve does blood pass from the right atrium to the right ventricle?

• Mitral valve

• Aortic valve

• Pulmonary valve

• Tricuspid valve

What is the role of the pulmonary arteries?

• To carry oxygenated blood to the heart

• To carry oxygenated blood to the body

• To carry deoxygenated blood to the heart

• To carry deoxygenated blood to the lungs

Which valve is also known as the mitral valve?

• Tricuspid valve

• Pulmonary valve

• Aortic valve

• Bicuspid valve

Why is the left ventricle myocardium thicker than the right?

• It receives blood from the body

• It receives blood from the lungs

• It pumps blood to the entire body

• It pumps blood to the lungs

What happens in the systemic capillaries during the cardiac cycle?

• Oxygen is absorbed by the blood

• Carbon dioxide is absorbed by the blood

• Oxygen is released into the tissues

• Carbon dioxide is released into the tissues
