Calculate the difference in blood pressure between the feet and top of the head of this person. To make sense of your answer, convert your answer to the unit of atm (101325 Pa = 1 atm). The density of blood is Pblood = 1.06 × 10³ kg/m³. b. Consider a cylindrical segment of a blood vessel 2.00 cm long and 1.50 mm in diameter. What additional outward force would such a vessel need to withstand in the person's feet compared to a similar vessel in her head? c. Justify how you solved for the area of the blood vessel.arrow_forward
