Why is blood not spilling out if the surgeon is operating on for example stomach.
In: Biology
The circulatory system is a “closed system” so blood flow is contained within vessels (arteries,veins,capillaries etc.)technically there will be bleeding when the surgeon cuts from the small capillary beds that feed our skin but unless you sever one of the large vessels such as the iliac vein or the abdominal aorta you won’t see the blood gushing out like you do in the movies
