Explain what is the relationship between flow rate, the difference in blood pressure between the two ends of a horizontal vessel system and the resistance of blood to flow in the horizontal vessel system. Think of the analogy between blood flow and Ohm’s law. Include in your answer what is the role of vasomotion in flow rate.

Is it possible for blood pressure to decrease to such a degree that capillary exchange ceases? Explain.

Discuss the physiological mechanisms that regulate arterial blood pressure. in detail give examples to back answer.

Which of the following would promote the filtration of fluid out of a capillary and into the interstitial fluid? Group of answer choices An increase in hydrostatic pressure in the interstitial fluid An increase in both hydrostatic pressure in the interstitial fluid and colloid osmotic pressure if the blood plasma An increase in colloid osmotic pressure if the blood plasma An increase in hydrostatic pressure in the capillary
