When Jessica cuts the goon's arm, she tells him that he will bleed 30 liters per minute. The blood flow through a brachial artery is nowhere near that much. During vigorous exercise the entire heart puts out a total of 30 liters per minute, but that's the sum total flow through every artery of the body. The flow though a single brachial artery is fraction of that. In addition, the goon was not vigorously exercising. At rest, the cardiac output is about 5 liters per minute.
