Components of a Stethoscope:

1. Ear Tips: These are the parts that fit into the user’s ears. They’re typically made of a soft material to provide comfort during use.
2. Binaurals/Tubing: These are the metal parts that connect the ear tips to the tubing. The tubing carries the sound from the chestpiece to the ears.
3. Chestpiece: This is the part placed on the patient. It generally consists of two sides:
   • Diaphragm: The larger flat side that’s used for listening to higher-frequency sounds like heartbeats.
   • Bell: The smaller, cup-shaped side for listening to lower-frequency sounds, such as certain heart murmurs or bowel sounds.
4. Stem: This connects the chestpiece to the tubing and often contains a mechanism to select either the diaphragm or bell.
