A) external respiration The open end of the cartilage rings faces posteriorly toward the esophagus, allowing the esophagus to expand into the space occupied by the trachea to accommodate masses of food moving through the esophagus. a. small cell carcinoma External respiration is the exchange of gases between the air filling the alveoli and the blood in the capillaries surrounding the walls of the alveoli. Inferior to the epiglottis is the thyroid cartilage, which is often referred to as the Adam's apple as it is most commonly enlarged and visible in adult males. Cilia on the surface of the epithelial cells move the mucus superiorly toward the pharynx where it can be swallowed and digested in the gastrointestinal tract. c. increased carbon dioxide in the blood Epiglottis is a leaf shaped cartilage that protects airway from aspirating food/drinks when swallowing. It prevents food and liquid from entering the trachea and harming the lungs.

Finally, the muscles of respiration, including the diaphragm and intercostal muscles, work together to act as a pump, pushing air into and out of the lungs during breathing. It is a component of the respiratory tract, and has several important functions, including phonation, the cough reflex, and protection of the lower respiratory tract. The larynx, also known as the voice box, is a short section of the airway that connects the laryngopharynx and the trachea. From the current view (layout view) group this report by values in the classification field, In a mixture of 75 litres the ratio of milk to water is 2:1.
