Study Notes
Stethoscope and Heartbeat
- After making a stethoscope, you should use it to listen to your heartbeat and find your pulse rate.
- To find your pulse rate, you need to place your index and middle fingers on the wrist, just below the thumb, and count the number of beats in one minute.
Materials for Stethoscope Model
- A model of a stethoscope requires a few simple materials, including a balloon, a straw, and a small piece of clay or tape.
Heart Function
- The valves inside the heart are responsible for controlling the flow of blood, ensuring it moves in one direction.
- The septum is a thin wall of tissue that separates the left and right sides of the heart.
- The left side of the heart pumps oxygen-rich blood out of the heart to the rest of the body.
Comparing Pulse Rate
- To compare your pulse rate results with your partner, you should take turns measuring each other's pulse rates and record the results.
Heartbeat Facts
- A normal human heart beats around 70-80 times per minute.
- The heartbeat, or thumping sound, is produced by the contraction and relaxation of the heart muscle, which causes the valves to open and close.
- The purpose of using a stethoscope to listen to the heart is to detect and monitor the heartbeat and pulse rate.
