Answer:
Gas exchange is crucial to sustain life because it rids the body of carbon dioxide and provides oxygen to the body.
Explanation:
Gas exchange in living beings is a mechanism that involves the incorporation of oxygen (O₂) into the organism and the elimination of carbon dioxide (CO₂). This exchange takes place in the pulmonary alveolus and in cells and tissues.
- <em><u>During respiration, the inspired air - loaded with O₂ - is exchanged with the CO₂ contained in the blood, taking advantage of the former and eliminating the latter during expiration</u></em><em>.
</em>
- <em>When the oxygenated blood is taken to the tissues, O₂ is passed to the cells, which are deprived of the CO₂ produced by metabolism.
</em>
The reason why gas exchange is crucial for the sustain of life is because it is the mechanism that allows the entry of O₂ necessary for cellular functions, as well as providing a means of CO₂ elimination.
Answer:
Health-related fitness (HRF) is defined as the development of muscular strength and endurance, flexibility, cardiorespiratory endurance, and body composition.
<u>My daily activities are morning walk or running, cooking, office work on the computer system, playing badminton or cycling, night walk after dinner.</u>
Activities that help to improve HRF and maximize body potentials are walk or running, playing badminton or cycling, and night walk after dinner. These all activities keep lungs, heart, and circulatory system healthy and improve my endurance.
