During exercise, systemic blood flow (cardiac output; liters/min) may be four times higher than at rest. Surprisingly, pulmonary blood flow is the same as systemic blood flow, but pulmonary resistance to flow is six times lower than the systemic resistance to flow. Use the relationship MAP = (cardiac output)*(resistance) to show that mean pulmonary pressure is six times less than mean systemic pressure.

she will be charged $6

step-by-step explanation:

48 dollars divided by 200 beads equals .24 dollars a bead

.24 multiplied by 25 more beads equals 6 dollars as the total cost

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
