Fleshy lobes in the nasal cavity which increases its surface area.

C. There are several levels of breathing control. Match structures given in Column B to the appropriate descriptions provided in the Column A. Place the correct term or letter in the space provided before the number.

Column A _E__1. Smooth out basic rhythm of breathing set by the medulla. _D__2. Respiratory control center in the medulla. _F__3. Respond to overinflation of the lungs. _A__4. Respond to decreased oxygen levels in the blood.

Column B A. Chemoreceptors in the aortic and carotid bodies B. Intercostal C. Inspiratory center

_B__5. Nerves that carry activating impulses to the muscles of inspiration. D. Phrenic E. Pons Center F. Stretch receptors in the lungs D. Critical Thinking. In your own opinion, explain the following: 1. Another technique for artificial respirations is mouth-to- mouth resuscitation. The rescuer takes a deep breathe, blows air into the victim’s mouth, and then lets air flow out of the victim’s lungs. The process is repeated. Explain the following: a. Why do victim’s lungs expand? - Mouth-to-mouth resuscitation is a life-saving intervention in which you blow air into a person's mouth after they stop breathing. By expanding the chest artificially, rescue breathing can inhibit the blood flow to the heart. Take note that by breathing into another person's lungs, you can supply enough oxygen to preserve life. But do not give breaths too rapidly or too forcefully because by doing this it may cause air to be forced into the stomach, resulting in distention and less room for lung expansion. b. Why does air move out of the victim’s lungs? - Any measure that causes air to flow in and out of a person’s lungs is when natural breathing is inadequate or stops. Like for example when a person is chock, drown, inhaled gas or smoke it cause them run out of oxygen. In order to save the victim, the air must be moved in and out of the lungs so that the gases in the air sacs(alveoli) of the lungs are continually changed and refreshed. This air movement is commonly called breathing.

Reflection

-

Every part of our body needs oxygen to survive. We breathe in a way that allows the body to function the way it should. Everyday functions of the body like digesting our food, moving our muscles, or even just thinking, need oxygen. We breathe to keep us alive. Breathing uses chemical and mechanical processes to bring oxygen to every cell of the body and to get rid of carbon dioxide. Our body needs continual supply of oxygen to obtain energy to fuel all our living processes....
