What is "diaphragm"?

The diaphragm is a dome-shaped muscle located beneath the lungs and separates the chest cavity from the abdominal cavity in the human body. It plays a vital role in respiration by contracting and relaxing to facilitate breathing. When the diaphragm contracts, it flattens and moves downward, creating more space in the chest cavity and allowing the lungs to expand, filling with air. This is known as inhalation. When the diaphragm relaxes, it returns to its dome shape, causing the chest cavity to decrease in volume and air to be expelled from the lungs, which is known as exhalation. In addition to its role in respiration, the diaphragm also assists in other bodily functions such as coughing, sneezing, and maintaining proper posture.

What is a "diaphragm"?

A diaphragm is a type of birth control device that is a flexible, cup-shaped cover made of silicone or latex. It is inserted into the vagina to cover the cervix and block sperm from entering the uterus. The diaphragm must be used with spermicide, a special gel that helps to kill sperm, and should be left in place for several hours after sexual activity. It needs to be adjusted by a healthcare provider to ensure it fits correctly and provides effective protection against pregnancy. Additionally, it is important to place the diaphragm correctly and ensure it stays in place during sexual activity. The diaphragm can be removed and reused, but it should be checked regularly for fit and effectiveness.
