Heart Valves and Their Functions

The video tutorial explains the four main heart valves: tricuspid, pulmonic, mitral, and aortic. It details their anatomical locations and functions in preventing blood backflow during heart contractions. A mnemonic, 'Try Pulling My Arm,' is introduced to help remember the valve names in order. The video concludes with a call to explore further study guides and resources.

Which of the following is NOT one of the four main heart valves?

• Bicuspid valve

Where is the tricuspid valve located?

• Between the right atrium and right ventricle

• Between the left ventricle and aorta

• Between the right ventricle and pulmonary artery

• Between the left atrium and left ventricle

What is the primary function of heart valves?

• To regulate heart rate

• To oxygenate the blood
