factors responsible for holding the lungs to the thorax wall are ________. 51 52) The erythrocyte count increases after a while when an individual goes from a low to a high altitude because the ________. 52 53) Most inspired particles such as dust fail to reach the lungs because of the ________. 53 54) Which of the following is not possible? 54 55) Select the correct statement about the physical factors influencing pulmonary ventilation. 55 56) Select the correct statement about oxygen transport in
blood: 56 57) Which of the disorders below is characterized by
destruction of the walls of the alveoli producing abnormally large air spaces that remain filled with air during exhalation? What maintains the patency of trachea?However, the cartilages of the trachea, along with the muscles and soft tissues of the neck, maintain patency of the airway (see Fig. 14.10A).
What is serve to keep trachea open?The walls of the trachea (TRAY-kee-uh) have stiff rings of cartilage to keep it open. The trachea is also lined with cilia, which sweep fluids and foreign particles out of the airway to keep them out of the lungs.
What artery supplies the trachea?Most commonly, there is a superior, middle and inferior bronchial arteries responsible for bringing blood to the trachea and carina. The superior bronchial artery comes off the anteromedial aspect of the descending thoracic aorta lateral to the carina and posterior to the left main bronchus.
What reinforced the walls of the trachea?A normal trachea (windpipe) has many rings made of cartilage (a strong and flexible tissue).
