Answer:
1)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. There are also little hairs that help filter the air you breathe in, blocking dirt and dust from getting into your lungs.
2)The walls of trachea are supported by cartilaginous rings to prevent it from collapsing in the absense of gases. Answer: The "walls of trachea" are supported by "rings" to restrict it from "collapsing". "Trachea" is also referred as "windpipe" as it provides a "passage for air" and carries it to the lungs.
3)The visceral pleura covers the surface of the lungs, and the parietal pleura covers the inside of the thorax, mediastinum, and diaphragm. A thin film of serous fluid fills the space between the two pleurae. ... Entry of air into the interpleural space (pneumothorax) allows the lung to collapse and the chest wall to expand.
4)During heavy exercise, the demand for energy is high but the supply of oxygen to produce energy is limited. Therefore, anaerobic respiration takes places in the muscles cells to fulfil the demand for energy.
5)Air pollutants such as particular materials from fossil fuel combustion can cause inflammation in the lung and further impaired the reduced pulmonary function in COPD patients
