Anatomy & Physiology Flashcard WS 22

Front

What is the function of the tricuspid valve in the human heart?

Back

Blood passes from the right atrium into the right ventricle through this.

Front

What is the function of the bicuspid valve?

Back

The bicuspid valve allows blood to flow from the left atrium to the left ventricle and prevents backflow.

Front

Which valve is referred to as the bicuspid valve because the two cusps look like a bishop’s headdress?

Back

Mitral valve

Front

Name given to the five steps involved in filling the heart’s chambers and pumping the blood.

Back

Cardiac cycle

Front

What happens during atrial systole?

Back

The atria simultaneously contract after the passive filling of the ventricles

Front

Anika, a medical student, is studying heart conditions. She learns about a condition where a valve is damaged and allows blood under high pressure to leak backward. What is this condition called?

Back

Incompetent

Front

Term for a condition where a heart valve is stiff and does not open normally, impeding the outflow of blood.

Back

Stenosis

Front

What is the function of the semilunar valves?

Back

Guarding the exit from the ventricles

Front

In a busy city, a ________________________ must allow the blood to flow freely in one direction but then shut to stop any backflow, just like how traffic lights control the flow of vehicles at an intersection.

Back

valve

Front

A ________________________ is like a little parachute that fills with blood from the ventricle under pressure.

Back
