Study Notes
Heart Function and Pulse
- When the left ventricle contracts, it forces approximately 70ml of blood into the aorta and arteries.
- Arteries expand as blood is forced into them due to their elastic walls.
- As the wave of blood passes, arteries relax, only to expand again with the next wave of blood.
- The expansion and recoil of arteries is the pulse.
- Pulse serves as an indication of the frequency of the heart rate.
Pulse Rate (Heart Rate)
- Rate is defined as the number of pulse beats in a minute.
- Normal pulse rate (heart rate) ranges from 60 to 100 beats per minute.
- The average pulse rate (heart rate) is 72 beats per minute.
