Blood Vessels: Transportation Network 10. Discuss the relationship between blood pressure, blood velocity, and cross-sectional area 11. blood flow. Explain the effects of the nervous and endocrine systems on vasomotion in regulating Summarize briefly the effects of hydrostatic pressure, gravity, blood volume, vessel elasticity, cardiac output, blood viscosity, and resistance on blood pressure 12. List the factors that interact to regulate arterial blood pressure. Briefly characterize the action of each. 13. If, at the arterial end of a capillary, the blood hydrostatic pressure is 35 pressure is 23 mmHg, the tissue hydrostatic pressure is 22 mmllg, and the tissue osmotic pressure is 24 mmHg, determine the net filtration pressure moving materials into the interstitial space. Do your work in the space provided below. hydrostatic pressure is 35 mm/Hg, the blood osmotic 14. 21.4 Practical Lecture/Laboratory Learning Guide for Human Anatomy & PhysiologyExplanation / Answer
10. Pressure in a blood vessel is directly proportional to
the velocity of blood flow. If the velocity of blood flow
increases, the resistance is increased. So, the pressure
is increased.
Arterial blood pressure is inversely proportional to the
diameter of blood vessel. If the diameter decreases, the
peripheral resistance increases, leading to increase in
the pressure.
