Answer» The processes of inspiration (breathing in) and expiration (breathing out) are vital for providing oxygen to tissues and removing carbon dioxide from the body. Inspiration occurs VIA active contraction of muscles – such as the DIAPHRAGM – whereas expiration tends to be PASSIVE, unless it is forced.The respiratory mechanism is a way of controlling how much carbon dioxide is in the blood. Elevating arterial CO2 or decreasing pH increases the rhythmic stimulation of the respiratory muscles by the medulla. Normally control of CO2 is based on the rate and depth of ventilation.Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. The original substance is CALLED the fuel, and the source of oxygen is called the oxidizer. ... During combustion, new chemical substances are created from the fuel and the oxidizer. |
