Answer 1

Respiration is the movement of oxygen from the outside environment to the cells within tissues, and the transport of carbon dioxide in the opposite direction. The lungs add oxygen to the blood and remove carbon dioxide in a process called gas exchange. In addition to the lungs, your respiratory system includes airways, muscles, blood vessels, and tissues that help make breathing possible.During inhalation, the diaphragm is contracted which increases the volume of the lung cavity. During exhalation, the diaphragm is relaxed which decreases the volume of the lung cavity.

Running aerobically”, your muscles have enough oxygen to produce all the energy they need to perform. The waste products of aerobic respiration are carbon dioxide and water. These byproducts are easily expelled through the simple act of breathing. This is why your breath is carbon dioxide rich and moist.when there is NOT sufficient oxygen present. In this instance, the muscles do not have enough oxygen to create the energy you are demanding
