The right & left bronchus along with the pulmonary artery & vein enter into the lungs at the? A. Hilum B. Carina C. Alveolar ducts D. Right middle lobe

A. Hilum

Gas exchange in the lungs occurs in the? A. Bronchioles B. Alveolar sinus C. Alveolar sacs D. Segmental Bronchi

C. Alveolar sacs

The trachea splits at the _________ to form the ____________. A. Cricoid cartilage, secondary bronchi B. Thyroid cartilage, primary bronchi C. Carina, primary bronchi D. Hilum, secondary bronchi

C. Carina, primary bronchi

______________ delivers unoxygenated blood to the lungs. A. Pulmonary vein B. Aorta C. Left ventricle D. Pulmonary artery

D. Pulmonary artery

True or False: Inhaled oxygen travels down through the trachea, into the right and left bronchus, then into the segmental bronchi which branches even further into the lobar bronchi. True False

The answer is FALSE. Inhaled oxygen travels down through the trachea, into the right and left bronchus, then into the LOBAR BRONCHI which branches even further into the SEGMENTAL BRONCHI.

True or False: During gas exchange, carbon dioxide is transported across the capillary membrane to be exhaled while oxygen is transported across the capillary membrane to attach to the red blood cells. True False

True

True or False: The left lung has three lobes and the right lung has two lobes. True False

False

True or False: During inhalation, the diaphragm contracts upward to create positive pressure in the chest which allows the body to inhale oxygen. True False

False, During inhalation, the diaphragm contracts DOWNWARD to create NEGATIVE pressure in the chest which allows the body to inhale oxygen.
