Question

Q1-Complete the chart using accurate terminology.

Regions of nervous tissue that contain mostly nerve cell bodies.

Sara is a healthy 20-year-old and is running in an American 5km charity fundraiser. Her body’s demand for oxygen has increased and the amount of carbon dioxide her body is producing has increased. Her respiratory system will play a vital role in ensuring she successfully completes this race. Assume normal physiology and anatomy in addressing the specific questions below.

Sara has started the race and her breathing has settled into a pattern.  

Q2- Explain the mechanical and physiological process happening as she breathes in and out. Include in your answer, the two brain structures that make up the respiratory control centres and the name of the two nerves that regulate the activity of the respiratory muscles in this process

Answer 1

Explain the mechanical and physiological process of breathing in and out during a race. (include the two brain structures that make up the respiratory control centers and the name of the two nerves that regulate the activity of the respiratory muscles in this process) word count:250

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
