Cyanide prevents oxygen fromaccepting electrons at the end ofthe electron transport chain. Oneof the first symptoms of cyanidepoisoning is unconsciousness. Which of the following is a logicalexplanation for why the brain isaffected by cyanide more than therest of the body?

a. The brain runs out of oxygenbefore the rest of the body does.
b. Cyanide prevents oxygen frombeing used in the brain.

The answer is A.

Explanation:

In the case of cyanide poisining which prevents the oxygen from being used by the body, the brain is one of the first organs that gets effected because it uses around 20% of the total oxygen intake of the body and the other systems and organs mostly depend on the brain to function properly so the brain runs out of oxygen before the other parts of the body.

I hope this answer helps.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

i think the answer is g1
