Heart Anatomy and Function Assessment

The video tutorial explores the anatomy of a pig heart, focusing on identifying the anterior and posterior surfaces, understanding key structures like the pulmonary trunk, ventricles, oracles, and aorta, and tracing the blood flow through the heart. It also delves into the internal anatomy, highlighting the myocardium, AV valves, semilunar valves, and papillary muscles, providing a comprehensive overview of heart anatomy and function.

What is the key feature used to identify the anterior surface of the pig heart?

• The presence of the aorta

• The color of the pulmonary trunk

• The size of the left ventricle

• The position of the right atrium

Which artery is most likely to be involved in a heart attack due to blockage?

• Circumflex artery

• Right coronary artery

• Left anterior descending artery

• Posterior descending artery

What is the function of the auricles in the heart?

• To regulate heart rate

• To increase the volume of the atria

• To pump blood to the lungs

• To separate the ventricles

Which vessel is located behind the pulmonary trunk?

• Left pulmonary artery

• Superior vena cava

• Inferior vena cava

• Aorta

Where does the blood go after entering the right atrium?

• Left atrium

• Aorta

• Right ventricle

• Pulmonary veins

What is the role of the chordae tendineae in the heart?

• To separate the atria

• To pump blood into the ventricles

• To anchor the AV valves

• To open the semilunar valves

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

• Tricuspid valve

• Pulmonary valve

• Bicuspid valve

• Aortic valve

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

• Both have the same wall thickness

• The left ventricle has a thicker wall

• The right ventricle has more muscle fibers

• The right ventricle has a thicker wall

What is the function of the papillary muscles in the heart?

• To open the aortic valve

• To close the semilunar valves

• To prevent inversion of the AV valves

• To pump blood into the atria

Which valve allows blood to flow from the left ventricle to the aorta?

• Aortic semilunar valve

• Mitral valve

• Pulmonary valve

• Tricuspid valve
