What is the importance of keeping the nasal and oral cavity clear?

Keeping the nasal and oral cavity clear is important to ensure unobstructed airflow, prevent infections, and filter out dust, bacteria, and other harmful particles before they reach the lungs.

What is the importance of breathing in fresh air?

Fresh air provides a high oxygen supply necessary for efficient respiration. It also helps in reducing stress, improving lung function, and removing toxins from the body, leading to overall better health. Related Questions: Name the structure through which the exchange of gases can take place in plants. Name the ways through which a plant can … Read more

How do viral infections like COVID-19 affect bronchi?

COVID-19 affects the bronchi by causing inflammation and excessive mucus production, leading to airway obstruction. It can also damage the cilia, reducing their ability to clear mucus, which results in difficulty breathing and increased risk of secondary infections. Related Questions: Name the structure through which the exchange of gases can take place in plants. Name … Read more

What is the effect of exercise on the rate of breathing?

Exercise increases the rate of breathing because the body requires more oxygen for energy production. The respiratory muscles work faster, and the depth of breathing increases to supply more oxygen and remove excess carbon dioxide produced during exercise. Related Questions: Name the structure through which the exchange of gases can take place in plants. Name … Read more

How does the exchange of gases take place in alveoli?

Gas exchange in alveoli occurs by diffusion. Oxygen from the inhaled air diffuses across the thin walls of the alveoli into the blood capillaries, while carbon dioxide from the blood diffuses into the alveoli to be exhaled. The high surface area, moist lining, and thin walls of alveoli facilitate efficient gas exchange. Related Questions: Name … Read more

Why do plants not need a specialized respiratory system?

Plants do not need a specialized respiratory system because they have a large surface area relative to their volume, allowing direct gas exchange through stomata, lenticels, and root hairs. Additionally, the slow rate of respiration in plants does not require an extensive oxygen transport system like animals. Related Questions: Name the structure through which the … Read more

Why would very wet soil be dangerous to plants

Very wet soil can be dangerous to plants because excessive water fills air spaces in the soil, reducing oxygen availability for root respiration. This leads to root suffocation, causing poor growth, root rot, and even plant death. Related Questions: Name the structure through which the exchange of gases can take place in plants. Name the … Read more
