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:
Reduced blood flow to the myocardium.
Explanation:
Cardiovascular disease may be defined as the disease that affects the functioning of the heart and blood vessels. Different cardiovascular diseases are heart attack, arteriosclerosis and heart failure.
The heart problems mainly occur due to the irregular blood flow in the myocardium. The reduced blood flow in the myocardium causes the emergency medical situation for the patient. The individual requires proper medical attention.
Thus, the answer is option (A).
