Heart Anatomy and Function Assessment

The video tutorial guides viewers through the dissection of a pig heart, starting with preparation and identification of external structures. It then moves to dissecting the heart to explore internal structures, including valves and tendons. The tutorial concludes with a comparative analysis of the heart's anatomy, emphasizing the differences between the atria and ventricles, and the left and right sides of the heart.

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

• Identifying the coronary vessels

• Drawing a diagram

• Washing the heart with tap water

• Cutting open the ventricles

Which side of the heart is identified by its thicker walls?

• Left side

• Dorsal side

• Ventral side

• Right side

Which major blood vessel is NOT identified in the external structure section?

• Vena cava

• Pulmonary artery

• Aorta

• Coronary artery

What is the purpose of running water through the aorta and pulmonary artery?

• To note the heart's reaction

• To identify the valves

• To observe the flow of blood

• To clean the heart

What is revealed by cutting open the base of the pulmonary artery?

• Bicuspid valve

• Tricuspid valve

• Semilunar valves

• Coronary vessels

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

• Semilunar valve

• Bicuspid valve

• Tricuspid valve

• Coronary valve

What is the function of the heart tendons?

• To supply blood to the heart

• To separate the atria and ventricles

• To pump blood

• To hold the valves in place

Which structure is NOT part of the internal heart anatomy?

• Semilunar valves

• Coronary vessels

• Ventricles

• Atria

What is the main difference between the walls of the left and right ventricles?

• The left ventricle has thicker walls

• The right ventricle has thicker walls

• The left ventricle is smaller

• Both have the same thickness

What should be included in the labeled diagram of the internal structure?

• Only the atria

• Only the coronary vessels

• Only the ventricles

• All internal structures including valves and tendons
