The blank space in the statement “Air enters the lungs through hollow passages collectively known as the __, which terminate in grapelike clusters called _. The lungs are encased in the ____ membranes.” Introduction: The respiratory system of the human body primarily functions to aid gaseous exchange. It comprises manyorgans that assist in the process, eventually culminating by the exchange of oxygen and carbon dioxide between atmosphere and lungs. Respiratory system begins by inhaling oxygen through the nose, which then passes through the respiratory system and ends with exhaling out carbon dioxide.

Part A: Below is the step-by-step path of air through the respiratory system, but the steps are not in correct sequence. Put them in order, numbering them from 1 to 8. ______ Air enters the alveoli. ______ Carbon dioxide passes out of the bloodstream, and is eventually exhaled. ______ Cilia and mucus trap tiny particles found in the air, and warm and moisten the air. ______ Air moves through smaller and smaller passageways called bronchi. ______ The trachea, or windpipe, then carries the air to the lungs. ______ Air enters the nose. ______ Oxygen passes into the bloodstream. ______ Air moves down the throat, or pharynx.

A small ridge of cartilage at the most inferior portion of the "windpipe" called the __________ now directs some air towards the left lung and some towards the right lung. The air will now travel through a series of tubes that become smaller and smaller as they repeatedly branch; these tubes, very similar in structure to the "windpipe", are called __________. Even tinier tubes continue branching; these tubes contain…

Smoking damages two parts of the respiratory system: the airways known as the [1] and small air sacs called the [2]. [3] in your airway helps capture debris (dust, smoke, pathogens) in the air you breathe, then structures called [4] sweep the [5] and debris out of your lungs. Cigarette smoke irritates the lining of your airway, causing it to [6]; this makes the diameter of your airway [7] and slows the movement of air. Smoke also slows the movement of [8]. Is a "smoker's cough" due to damage of alveoli or bronchial tubes? [9] Is a long-term smoker's difficulty breathing due to damage of alveoli or bronchial tubes? [10] [11] is a lung disease caused by damage to the alveoli.
