The pig's heart is about 8cm* 12cm, while the human heart weighs about 260 grams and has a volume of 750 ml. During contraction, 70 ml of blood is injected into the blood vessel at a time, 5000 ml is output every minute, and 7500 kg of blood is injected every 24 hours. The heart beats 60~ 100 times per minute.
To sum up, the size of a pig's heart is bigger than that of a human heart. But please note that this does not mean that the pig's heart is healthier or better, and the human heart also has its unique advantages.
