Heart Anatomy and Functions

This video tutorial guides students through the at-home dissection of a heart. It covers the identification of external and internal structures, including the atria, ventricles, and major vessels like the pulmonary artery and aorta. The tutorial emphasizes understanding the heart's anatomy and encourages hands-on exploration to reinforce learning.

What is the first step in preparing for a heart dissection?

• Identifying the top and bottom of the heart

• Removing the pericardium

• Labeling the heart structures

• Cutting the heart open

Which side of the heart is larger and contains the apex?

• Bottom side

• Left side

• Top side

• Right side

What is the function of the pulmonary artery?

• Carries blood to the body

• Carries blood to the right atrium

• Carries blood to the lungs

• Carries blood to the left ventricle

Where does the aorta originate from in the heart?

• Left atrium

• Left ventricle

• Right atrium

• Right ventricle

What is the role of the superior vena cava?

• Carries blood from the heart to the body

• Carries blood from the body to the right atrium

• Carries blood from the lungs to the heart

• Carries blood from the right ventricle to the lungs

Which vessels return blood to the heart from the lungs?

• Pulmonary veins

• Aorta

• Coronary arteries

• Pulmonary artery

What is the thick muscle layer of the heart called?

• Endocardium

• Myocardium

• Epicardium

• Pericardium

Which valve is located between the left atrium and left ventricle?

• Pulmonary valve

• Tricuspid valve

• Aortic valve

• Mitral valve

What is the function of the chordae tendineae?

• Transmit electrical signals

• Supply blood to the heart muscle

• Prevent backflow of blood

• Connect the heart to the lungs

Which valve is found at the exit of the right ventricle?

• Aortic semilunar valve

• Mitral valve

• Pulmonary semilunar valve

• Tricuspid valve
