Answer: The average human body has 8-10 pints of blood. The maximum amountof blood you can lose and still be functional is 33% or one-thirdof your blood. Eventually, your body will collapse and send youinto a temporary coma. If more than 66% or two-thirds blood islost, death is certain. If there is no blood coming in, than about40% blood loss is when people die.
Answer: Usually you probably would not pass out when a little bit of blood is drawn but if large quantities are taken out then your body doesnt have enough blood to function. Your brain needs blood to function as well as all the other organs. Eventually then your body just sends the blood away from places that are not as important and they send it to the heart and brain and eventually that may run out a little and you pass out XD
Answer: Low oxygen blood flows out of the heart through the pulmonarysemilunar valve and into the pulmonary trunk. From there is goesthrough the left and right pulmonary arteries into each respectivelung.
Answer: Christ certainly sweat lots of perspiration and blood during the atonement. He even lost some more when he was nailed to the Cross. When the guards pierced his left side, the rest of his blood poured out, and then came water. Christ died of loss of blood and shortage of breath.

Answer: he vascular system is made up of the vessels that carry our blood. Arteries carry oxygen-rich blood away from the heart. Veins carry oxygen-poor blood back to your heart. There is one exception to that statement; when the blood starts its vascular system trip at the right side of the heart, it is the pulmonary artery that carries the oxygen-poor blood to the lungs where it exchanges carbon dioxide for oxygen. Then the pulmonary vein carries oxygen-rich blood back to the heart. The blood goes back to the left side of the heart and is pumped out to the rest of the body. The main artery leading from the heart to the rest of the body is called the aorta. As the blood travels, it enters smaller and smaller blood vessels, reaching every cell in the body, dropping off nutrients and picking up waste products and carbon dioxide. The blood then starts the trip back in the veins, entering larger and larger ones as it goes, passing through the liver on the way to drop off waste products. The blood eventually arrives back at the right side of the heart to start the trip all over again.
