Answer:
A: Oxygen levels are low and, therefore, more red blood cells are produced, giving the athletes an advantage when competing at lower altitudes.
Explanation:
<em>At high altitudes, the partial pressure of oxygen is lower compared to lower altitudes</em>. The body system try to adjust to lower oxygen level by undergoing several physiological changes. Depending on the duration spent in high altitude, the body can either try to adjust in the short term or acclimatize for a longer term.
One of the processes the body undergoes during acclimatization is an increase in red blood cell production. The kidney secretes erythropotein in response to inadequate oxygen in body tissues, and this makes the liver to increase erythrocyte production.
The increase in red blood cell production correspondingly increases the oxygen-carrying capacity of the blood as a result of increased hemoglobin. This condition persists for a few weeks even after the body returns to lower altitude where oxygen is adequate. Increased oxygen capacity means the rate of energy production (through respiration) within the body will also increase
<em>Hence, those who acclimatize to high altitude usually experience increased capillary density, tissue perfusion and improved athletic performance at lower altitudes. </em>
The correct option is A.
Cortisol hormones are stress hormones that increase blood glucose levels. When the level of happiness increases the level of cortisol does not increase.
<h3>What are cortisol and its function?</h3>
Cortisol is the steroidal hormone that is produced in the cortex of the adrenal glands and is discharged in the blood vessels when in stress or danger.
It has a variety of functions including regulation of the blood pressure, response to the stressful condition and increase of the metabolism of the body.
It also acts as happiness hormones along with adrenaline and oxytocin but is a major flight or fight hormone and increases the heart rate in dangerous conditions.
Therefore, the statement is false.
