Afterload

Afterload

• Afterload is the tension or stress that the heart must generate to eject blood into the aorta during systole.

Factors Contributing to Afterload

• End systolic volume (ESV) is increased by: • Increased peripheral resistance • Increased blood pressure • Stiffening of arteries • Decreased arterial compliance

Note: Peripheral resistance, blood pressure, and arterial stiffness all contribute to increased afterload, making it more difficult for the heart to pump blood.

Test your knowledge on afterload and its impact on the heart's ability to pump blood efficiently. This quiz covers topics such as aortic pressure, arterial wall rigidity, and blood viscosity, all of which contribute to afterload. Challenge yourself with questions specific to this important aspect of cardiovascular health.
