This question was posed to me by my Biology teacher:
Consider a hypothetical emergency situation of a person shot by a bullet in the heart. The bullet goes into the body and comes out from it, causing a total of two "holes" in the heart, one each in the "dorsal" as well as "ventral" side of the heart. Blood starts coming out.
Now in an ordinary situation, if the blood continues to flow out, the person will die. But there is a twist, the person has been given an infinite supply of blood from some sort of medical equipment. (Nothing like this actually exists in real life, but you might consider this a "conceptual Biology textbook problem".) The person's heart beats at a normal rate of ~72/second.
Now here is the question :
Considering, the "infinite" supply of blood available, will the person survive?
Will the heart develop some sort of clot or something similar to prevent further leakage of blood, as it forms due the cuts on arms or legs? Is some medical assistance required besides the "infinite" supply of blood?
NOTE : You might make the following assumptions ---
There is no doctor/surgeon to help. Just you and your faithful "machine".
The blood provided by the "machine" is 100% compatible with the blood group of the person.
The "machine" is connected in such a way that after the complete loss of the "original" blood of the person, now the blood provided by "machine" runs in the arteries of the person.
The veins and arteries of the person are 100% OK. The only part affected is the heart "perforated" by the bullet.
