explanation
1)The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax)
2)Gas exchange takes place in the millions of alveoli(airsacs) in the lungs and the capillaries that envelop them.
3)Bronchioles end in tiny air sacs called alveoli, where the exchange of oxygen and carbon dioxide actually takes place. Each person has hundreds of millions of alveoli in their lungs.
4)The larynx, commonly called the voice box or glottis, is the passageway for air between the pharynx above and the trachea below. ... The larynx plays an essential role in human speech
5)Mouth, also called oral cavity or buccal cavity, in human anatomy, orifice through which food and air enter the body.
6)The throat (pharynx) is a muscular tube that runs from the back of your nose down into your neck.
7)The nasal cavity is the inside of your nose. It is lined with a mucous membrane that helps keep your nose moist by making mucus so you won't get nosebleeds from a dry nose.
8)nose is an organ of the respiratory system found protruding between the eyes
9)the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs.
10)The trachea(windpipe) begins just under the larynx (voice box)and runs down behind the breastbone (sternum).
