I believe it is B. Because during vigorous exercise, the heart rate and depth of breathing increases to supply muscles with more oxygen.
<span>A communicable disease is a disease that can be
passed from person to person. It can also occur from an animal to a person or
vice versa. Airborne viruses, bacteria, blood, and bodily fluids can cause the
spread of these diseases. When things are infectious or contagious it also
refers to communicable diseases. The most common communicable disease is the flu,
which can easily spread in an enclosed environment with a recycled circulating
air (e.g. air-conditioning). Infectious disease caused by blood contact like
HIV/AIDs are also dominant in society. </span>
Answer:
can you add the scenarios please?
Answer: The correct option is IRON DEFICIENCY ANAEMIA
Explanation:
Anaemia is a condition that arises when there is not enough haemoglobin available to carry sufficient oxygen from the lungs to supply the needs of the tissues. It occurs when the rate of production of mature cells entering the blood from the reb bone marrow does not keep pace with the rate of haemolysis.. Anaemia can be classified based on:
--> impaired erythrocyte production example, Iron deficiency anaemia. Or
--> increased erythrocyte loss example, haemolytic anaemia.
IRON DEFICIENCY ANAEMIA occurs when the amount of iron nutrient needed in the body system for the production of haemoglobin is decreased. The symptoms includes
- impaired work performance,
- general fatigue,
-pale skin,
- depressed immune function,
- impaired cognitive and nerve function, and impaired memory.
