Doctors do not administer vaccinations to people who are too sick. Which best explains why?
4vir4ik [10]

Answer:

D, The white blood cells of sick people may not be able to efficiently handle the weakened or dead form of the pathogen.

Explanation:

Vaccinations are essentially just weak diseases we use to create antibodies so the body can protect itself from the full disease. If it sees it once, it can defend itself, is the theory. This is choice D.

  • Why not A: The weakened form will be attacked by the immune system, but maybe not enough, because the person is so sick that the immune system is busy elsewhere.
  • Why not B: The medication is not what combines with the vaccine to cause problems. It is the body being overworked.
  • Why not C: The digestive system isn't the issue. You don't eat diseases.

The phase in the cardiac cycle when the mitral valve is closed and the aortic valve is open is the A) atrial systole. B) early d
KengaRu [80]

The phase in the cardiac cycle when the mitral valve is closed and the aortic valve is open is the systolic ejection phase (Option D). It is the second phase of the ventricular systole.

The cardiac cycle is a sequence of contraction and relaxation of the atria and ventricles to pump blood throughout the body.

This cycle (cardiac cycle) can be divided into two major periods: diastole and systole.

The diastole is when the heart relaxes and refills with blood, while the systole is when the heart contracts and pumps blood.

The systolic ejection phase is the second phase of the ventricular systole where blood is pumped from the ventricle.
