Answer 1

Answer:

One of the most common reasons people faint is in reaction to an emotional trigger. For example, the sight of blood, or extreme excitement, anxiety or fear, may cause some people to faint. This condition is called vasovagal syncope

Answer 2

It happened because a. Blood cells didn't get the necessary amount of oxygen to the body parts.

• Dizziness is a condition where people struggle to maintain balance and feel lightheaded. It may lead to fainting.
• It is caused due to the inability of blood cells (RBCs) to carry adequate oxygen to the brain cells (neurons).
• This may happen due to lack of oxygen in the surroundings, anemia, hypotension, or dehydration.
• When feeling dizzy, the first step is to sit or lie down until the head feels a little normal. After that having water with some salt or electrolytes is a good treatment.
