D) larynx The primary bronchi contain many C-shaped cartilage rings that firmly hold the airway open and give the bronchi a cross-sectional shape like a flattened circle or a letter D. As the bronchi branch into secondary and tertiary bronchi, the cartilage becomes more widely spaced and more smooth muscle and elastin protein is found in the walls. b. oxygen Larynx: cartilaginous tube; surrounds/ protects glottis (voice box); three large cartilages (epiglottis, thyroid cartilage, cricoid cartilage) a.

When breathing in, air enters the larynx through an opening called the _________. pg. Each lung is surrounded by a pleural membrane that provides the lung with space to expand as well as a negative pressure space relative to the bodys exterior.

The negative pressure allows the lungs to passively fill with air as they relax. Compute and display the bank's service fees for the month. The thyroid cartilage is the largest of the laryngeal cartilages and is composed of hyaline cartilage. Epiglottis protects the superior opening of the larynx when we swallow food or fluids, the larynx is pulled upward and the epiglottis tips, forming a lid over the opening of the larynx routing the food into the esophagus.

Drake, R., Vogl, W., Mitchell, A. 438, What role do the tonsils play in the respiratory system? D) internal respiration 445, Air flowing out of the lungs is known as ____. The alveoli are cup-shaped structures found at the end of the terminal bronchioles and surrounded by capillaries. pg. e. pleurisy a. asthma 440, Each main (primary) bronchus enters the lung at the apex. a. pg. pg. This is due to the influence of the hormone testosterone, which stimulates the overall growth of the larynx resulting in a deeper voice with time.
