WebbThe most readily observable component of respiration involves the act of breathing, “during which the lungs are provided with air through inhaling and CO 2 is removed through exhalation.” 2 This process of moving air into and out of the lungs is known as ventilation. 1 While it may seem a simplistic process, the ability of air to flow into and out of the … WebbFalse (viral or bacterial infection is) If the partial pressure of oxygen is higher in the alveoli than in the blood, which phrase describes the net movement of oxygen.
