What is a mammal’s diaphragm?
Human BodyRespiration
Quick Answer
The diaphragm is a dome-shaped muscle that helps mammals breathe by expanding the chest cavity. It is a defining feature of mammalian respiration.
The Full Story
When the diaphragm contracts, it flattens and enlarges the space in the chest, drawing air into the lungs. When it relaxes, the chest cavity becomes smaller and air moves out. This muscle works continuously and is crucial for efficient breathing in mammals. Because mammals have a diaphragm, their breathing mechanism differs from that of birds and many reptiles.
