Answer:

Parts of human heart and its role and functions are explained below in details.

Explanation:

The heart is a muscular organ about the dimension of a hand, positioned just back and slightly left of the breastbone. The heart elevates blood through the system of veins and arteries called the cardiovascular arrangement.

The heart has four chambers:

  • The right atrium receives serum from the veins and elevates it to the right ventricle.
  • The left side atrium carries oxygenated blood from the lungs and elevates it to the left ventricle.
  • The right ventricle takes blood from the right atrium and elevates it to the lungs, where oxygen is filled.
  • The left ventricle elevates oxygen-rich serum to the remainder of the body. The left ventricle strong contractions produce our blood pressure.

ratelena [41]


I'm not sure if I understood correctly your question .
Two ways HIV/AIDS not spread through sex ...

By blood transfusion (there was a scandal in France and other countries in the eighties ....many people got HIV because of this ; it was called the scandal of contaminated blood...)


The other one could be a fight between two people with severe bleeding injuries; if one of them is HIV, it may contaminate the other one.
Or someone willing to help and look after a cut, if this person has a small cut as well, he may be contaminate by blood.

As blood is the only way of contamination, people have to be careful when helping someone bleeding if they are bleeding too.

Usually, in hospitals, dentists, they have to use gloves
