1.a decrease in oxygen uptake decrease in oxygen uptake
2.an increase in red blood cells an increase in red blood cells
3.an increase in resting heart rate increase in resting heart rate (Not the answer)
4. a decrease in cardiac output

Answers

Answer 1

Answer:

an increase in red blood cells an increase in red blood cells

Explanation:

Answer 2

Answer:

The physiological change that is most likely to occur in Jane's body due to aerobic exercise is an increase in red blood cells.

Explanation:

One of the most notorious changes in blood circulation in people in aerobic exercise is the increase in red blood cell mass.

Red blood cells are responsible for transporting oxygen (O₂) to tissues. The increased demand for oxygen by the muscles, due to frequent physical exercise, causes the amount of red blood cells and hemoglobin —the molecule that carries O₂— to increase.

The other options are not correct because:

1. Oxygen uptake increases, due to the existence of a greater number of red blood cells and greater demand for this gas. 3. Heart rate at rest decreases, as part of physical conditioning. 4. Cardiac output increases.

What are some of the advantages and disadvantages of a career in the health sciences? After reading the unit and researching a few health careers, how easy do you think it is to change jobs within different health service sites, or even between different healthcare roles?

Answers

Answer:

I do not have access to the learning unit you used, but I will still give you a useful answer that can serve as an example.

Explanation:

The reasons for a career in the health sciences go beyond the fact of "knowing" medicine, since it is a commitment to the health of communities, individuals, families and their environments; as well as with human values ​​and the preservation of life.

Among the main advantages, personal satisfaction stands out in the first place. Also, health professionals enjoy great social prestige and receive high salaries; compared to professionals from other university formations.

Lastly, health professionals transmit great security to their families; and possibly they can save the life of a relative in case of accident, heart attack or other illness.

On the other hand, we have disadvantages such as the preparation and study time that this demanding profession requires.

If you decide to study medicine, according to the chosen specialty, doctors must be on duty at night on numerous occasions, with the consequent inconvenience that this type of schedule entails in a family structure.

Finally, the training of the doctor never ends.

That is why it is not so easy to change jobs within the different health service sites, since each specialist must have complete knowledge of their work area, since what is at stake is the health and lives of beings humans.
