Answer:
Mitral stenosis causes reduced blood flow through the narrowed valve opening from the left atrium to the left ventricle. As a result, the volume of blood bringing oxygen from the lungs is reduced. This can make you feel tired and short of breath.

Calories are a unit for the measurement of the amount of energy in different foods and drinks.
Pharmacists are responsible for the distribution of medication, which is not measured in calories so it is not A.

Finally life technicians identify and collect loving organisms to study so they don't use calories either.
A nutritionist's is to evaluate the chemical make up of different foods i.e. How much energy hence calories, and how they work with different people's bodies, therefore B is correct.
Hope this helped!
Answer:
1. The blood entering the right side of the body contains <u>un-
oxygenated</u> blood (B).
2. All arteries carry oxygenated blood EXCEPT the <u>pulmonary</u> artery.
3. What structure brings blood to the right atrium? Superior and inferior vena cava (D).
Explanation:
The cardiovascular system is responsible for getting blood to organs throughout the body, through the joint function of the heart and blood vessels.
The circulation of the blood has been divided into two circuits:
- The major circulation, which includes the exit of blood from the heart to the arterial system, to go to the whole body. This circuit is closed with the arrival of blood to the heart through the system of venous vessels.
- The minor circulation consists of the passage of blood from the right ventricle to the lungs, and from these to the left atrium.
The blood that reaches the right atrium —entering to right side— proceeds from the superior and inferior vena cava, and is non-oxygenated blood.
In the minor circulation, the pulmonary arteries exit the right ventricle, carrying non-oxygenated blood to the lungs, being the <u>only arteries to carry venous blood</u>.
