- Capillaries Explain the direction and the rate of flow in the capillaries. Does the rate remain constant or does it fluctuate from time to time? Does the direction of blood flow ever change? What limits a capillary from being smaller than a certain size? Are any capillaries dead-end sacs? Are all cells directly adjacent to a capillary, thus providing a simple passage for food, dissolved gasses, and wastes?What would be the behavior of an object that was immersed in a fluid if the object and the fluid had the same density? Explain.4
- 3. DETAILS A medical patient's femoral artery has an internal cross-sectional area of 0.38 cm² and a blood volume flow rate of 2.30. min Determine the blood flow speed through the artery (round to the nearest thousandth). m S MY NOTES m S ASK YOUR TEACHER Plaque buildup in one region of the artery creates a smaller cross-sectional area of 0.13 cm². Determine the blood flow speed through this partially blocked region of the artery (round to the nearest thousandth). If the blood pressure through the unobstructed artery is 14250 Pa, determine the blood pressure through the partially blocked region. Assume blood has the same density of water, blood-1000 kg Pa m3pls helpl.l..1. Suppose a person is 182 cm tall. A typical blood pressure is often given as 110/70 mm Hg, with a mean pressure of 80 mm Hg. A. Do you think this is the gauge pressure or absolute pressure? Why? If the pressure at the top of the head is about 39 mm Hg, how far away is this person's head from the heart? Assume the density of blood is about 6% higher than that of water. t, What then would be the blood pressure.of this 6, person at their feet? b. Suppose this person suffers a puncture wound around the same height as the heart where the opening is about 3 mm in diameter. How far could blood shoot from their body assuming it comes out horizontally with 0 m/s initial horizontal velocity? %3D = 0.754 Since horizontal velocity is zero it will not go eny for than body Please explain the variábles used in the equation to solve for F= P.A in partad of this question.

- #3The blood speed in a normal segment of a horizontal artery is 0.116 m/s. An abnormal segment of the artery is narrowed down by an arteriosclerotic plaque to 1/4 of its normal cross-sectional area. What is the difference in blood pressure between the normal and constricted segments of the artery? Number i UnitsBlood is flowing through an artery of radius 6 mm at a rate of 43 cm/s. Determine the flow rate and the volume (in cm/s) that passes through the artery in a period of 10 s. flow rate cm/s volume cm3
