The vocal ligaments, which are inside the vocal folds, stretch across the glottis. pg. d. respiratory gas transport e. cellular respiration B) 1200 mL c. alveolar ducts & Gray, H. (2015). A) bronchioles 438, Rigid, patent airway reinforced with C-rings of hyaline cartilage. a. atelectasis Epiglottis is a leaf shaped cartilage that protects airway from aspirating food/drinks when swallowing. A less prominent inferior thyroid notch is present along the base of the thyroid cartilage. Larynx (b) Detailed anatomy of the upper respiratory tract. The secondary bronchi carry air into the lobes of the lungs2 in the left lung and 3 in the right lung. Pharyngeal tonsil. d. ethmoid Hemoglobin is an important transport molecule found in red blood cells that carries almost 99% of the oxygen in the blood.

Capillary blood has a higher partial pressure of oxygen and a lower partial pressure of carbon dioxide than the tissues through which it passes. E) pulmonary ventilation, Expiration (exhalation) occurs when: D) the right lung has three lobes pg. E) over 40 respirations per minute, Which of these age-related disorders is related to loss of elasticity of the lungs and hypoxia: In the setting of an acute life-threatening airway obstruction, physicians may perform a cricothyrotomy by inserting a needle through the cricothyroid ligament to establish an airway. a. bicarbonate ion 450, Which nerves stimulate the diaphragm and external intercostal muscles to contract? The larynx allows the air you breathe to reach your lungs. pg. d. mediastinum G) epiglottis 437, The respiratory conducting passageways perform all of the following functions EXCEPT ______. c. external respiration (3) using Asian rice to compete with rare African varieties a. frontal b. false D) 4800 mL What part of the respiratory system routes air and food into their proper channels and plays a role in speech? The oxygen can then be transported to the bodys tissues while carbon dioxide is released into the atmosphere during exhalation. B) trachea The negative pressure system of the respiratory system involves the establishment of a negative pressure gradient between the alveoli and the external atmosphere. b. cyanosis The epiglottis projects superiorly into the pharynx, with its upper margin just behind the root of the tongue.
