No. The diaphragm is a muscle below the lungs that aids in drawing in air to the lungs more completely when you take a deep breath. A strong diaphragm also aids in breath cont â¦ rol, especially in athletes and singers. Deep breathing is good for everybody, and should be practiced for optimal lung expansion.aking the world better, one answer at a time. when the diaphragm contracts down it flatten the thoracic cavity floor thus expanding the lungs in a inferior direction.
The heating and ventilating industry installs innovative systems and new technologies such as air and ground source heat pumps to make buildings as energy efficient as possible. To do this, the industry requires highly-trained engineers who have the skills to install increasingly complex systems. Heating and ventilating engineers may be involved in a diverse range of duties: Pipework and Ductwork Installers use their skills to cut, form, weld and join a wide range of materials used within a heating and ventilating system.
A furnace works by blowing heated air through ducts that deliver the warm air to rooms throughout the house via air registers or grills. This type of heating system is called a ducted warm-air or forced warm-air distribution system. It can be powered by electricity, natural gas, or fuel oil. Inside a gas- or oil-fired furnace, the fuel is mixed with air and burned. The flames heat a metal heat exchanger where the heat is transferred to air.
