Questions and Answers

What is the primary function of the fibrous skeleton of the heart?

To assist in the contraction of the ventricles
To facilitate the conduction of electrical impulses
To increase the heart's pumping efficiency
To anchor valve flaps and prevent valve stretching (correct)

What is the role of the right side of the heart?

To separate the atria from the ventricles
To pump blood to the lungs for oxygenation (correct)
To distribute oxygenated blood to the body
To receive oxygenated blood from the body

How do the atria and ventricles of the heart contract?

Both atria and ventricles contract simultaneously (correct)
The atria and ventricles contract independently
The atria contract before the ventricles
The ventricles contract before the atria

Flashcards

Fibrous skeleton of the heart

Connective tissue anchoring heart valves, preventing over-stretching and isolating atrial and ventricular contractions.

Right heart function

Receives deoxygenated blood, pumps it to lungs for oxygenation.

Left heart function

Receives oxygenated blood from lungs, pumps to body.

Simultaneous heart contraction

Atria contract together, followed by ventricles contracting together.

Study Notes

Fibrous Skeleton of the Heart

Fibrous connective tissue anchoring valve edges
Prevents valve flaps from stretching
Separates myocardium of atria and ventricles
Prevents atrial contraction from reaching ventricles except via normal conduction pathway

Heart Function

Heart is a double (two-sided) pump
Right side receives deoxygenated blood from body, pumps it to lungs to pick up oxygen and release carbon dioxide
Left side receives oxygenated blood from lungs, pumps it to body
Both atria contract together, followed by both ventricles contracting simultaneously
