<h2>Answer 13:</h2>

Affect of exercise on the circulatory system:

Exercise improve the circulation of blood throughout our body.
This provides the muscles with the necessary oxygen and nutrients to provide the muscles with energy.
The systemic circulatory system includes blood vessels that deliver oxygen and nutrient-rich blood to tissues throughout your body.

Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs.

Ventilation is the process that moves air into and out of the alveoli, and perfusion affects the flow of blood in the capillaries.
External respiration refers to gas exchange that occurs in the alveoli
whereas internal respiration refers to gas exchange that occurs in the tissue.

Answer:

The main purpose of these therapies are to suppress the immune system and destroy cancer cells of the blood by destroying the ability of the body to produce blood cells inside the bone marrow in preparation of the bone marrow for the new stem cells from the donor.

Explanation:

In the treatment of acute myeloid leukemia (AML), hematopoietic stem cell transplantation (HSCT) procedure is employed. It involves the infusion of healthy blood-forming stem cells from a donor into the body of the patient to initiate production of healthy blood cells after the hematopoietic function of the bone marrow of the patient has been destroyed by chemotherapy and radiation.

Before the stem transplant, the patient is subjected to a conditioning process or therapy, which involves undergoing a treatment through chemotherapy and radiation therapy. <em>The main purpose of these therapies are to suppress the immune system and destroy cancer cells of the blood by destroying the ability of the body to produce blood cells inside the bone marrow in preparation of the bone marrow for the new stem cells from the donor. </em>

After these therapies, the transplant infusion takes place, which is usually painless.
