The diaphragm is a muscle that sits under the lungs and heart, separating the thoracic cavity from the abdominal cavity. It is involved in respiration, helping you breathe by drawing downward in the chest on inhalation, and pushing upward in exhalation. The diaphragm can be viewed as two distinct muscles, the crural and the costal diaphragm, which act in synchrony during respiration.

What You'll Learn
The diaphragm is a thin, dome-shaped muscle
The diaphragm is a muscle that helps you breathe. Many conditions, injuries and diseases can affect how the diaphragm works, causing symptoms such as trouble breathing and chest pain. Just like any other muscle in your body, you can strengthen it with exercises. Diaphragmatic breathing exercises can help your diaphragm work more efficiently. They also reduce stress and help you feel better.

It separates the thoracic cavity from the abdominal cavity
The diaphragm is a muscle that helps you breathe. It sits under your lungs and separates your chest cavity from your abdomen. It is a thin, dome-shaped muscle which separates the thoracic cavity (lungs and heart) from the abdominal cavity (intestines, stomach, liver, etc.). It is involved in respiration, drawing downward in the chest on inhalation, and pushing upward in exhalation.
The diaphragm should be viewed as two distinct muscles, crural and costal, which act in synchrony throughout respiration. However, the activities of these two muscular regions can diverge during certain events such as swallowing and emesis. For example, transient crural muscle relaxations herald the onset of spontaneous acid reflux episodes.
Many conditions, injuries and diseases can affect how the diaphragm works, causing symptoms such as trouble breathing and chest pain. Breathing exercises can strengthen your diaphragm and keep it working like it should.

It is involved in respiration
The diaphragm is a muscle that helps you breathe. It sits under your lungs and separates your chest cavity from your abdomen. It is involved in respiration, drawing downward in the chest on inhalation, and pushing upward in exhalation.
The diaphragm should be viewed as two distinct muscles, crural and costal, which act in synchrony throughout respiration. However, the activities of these two muscular regions can diverge during certain events such as swallowing and emesis.
The diaphragm has traditionally been studied as a respiratory muscle. However, there is mounting evidence that suggests that it should more correctly be characterised as two separate muscles, the crural diaphragm and the costal diaphragm.
Breathing exercises can strengthen your diaphragm and keep it working like it should.

It can be viewed as two distinct muscles: crural and costal
The diaphragm is a muscle that helps you breathe. It sits under your lungs and separates your chest cavity from your abdomen. It is a thin, dome-shaped muscle.
The diaphragm can be viewed as two distinct muscles: crural and costal. These two muscular regions act in synchrony throughout respiration, but their activities can diverge during certain events such as swallowing and emesis. The crural diaphragm develops in the mesentery of the oesophagus, while the costal diaphragm develops from myoblasts originating in the body wall.

Frequently asked questions
The diaphragm is a thin, dome-shaped muscle that sits under your lungs and separates your chest cavity from your abdomen.
The diaphragm is involved in respiration, helping you breathe in and out by drawing downward in the chest on inhalation, and pushing upward in exhalation. It also helps to stop gastric contents from refluxing into the oesophagus.
Just like any other muscle in your body, you can strengthen your diaphragm with exercises. Diaphragmatic breathing exercises can help your diaphragm work more efficiently, reduce stress and help you feel better.
