Consider microcirculation and the selective deployment of blood to capillary beds. What about the anatomy of microcirculation makes this possible? How is this used to respond to external stresses (like temperature) and internal metabolic demands?

Expert Solution

Microcirculation deals with the microvessels through which the the blood pasess, they are arterioles, cappilaries etc. The blood flowing through the capillary bed is not constant like all other blood vessels. There also occurs selective control of blood flow to the areas where they are necessary. They are done by the help of the precapillary sphincter. They are ring like arrangements of the smooth muscle seen in the capillaries which help in this control. They have the ability to contract and control the blood flow to the selected when necessary. The micro circulation in the skin else known as cutaneous microcirculation is used to exchange the water and the minerals to protect against the external stress like temperature. During internal metabolic demands this specific function of the microcirculation makes it expand and increase the blood flow to the necessary area so as to increase the nutrient flow too these regions.

In capillary beds, there is mass movement of fluids and molecules into and out of capillary beds. For movement of fluids, simple diffusion is not sufficient and two pressure-based mechanisms are utilized. Describe the action of the competing forces driving filtration of fluids in a capillary bed. Describe the action of the competing forces driving reabsorption of fluids in a capillary bed. Predict how physiological changes in the capillary beds in response to an increase in body temperature restores homeostasis.

Lymphedema is a disorder in which the lymphatic vessels associated with capillary beds are blocked. What will be the long-term effect of lymphedema? Lymphedema is a disorder in which the lymphatic vessels associated with capillary beds are blocked. What will be the long-term effect of lymphedema? the accumulation of more fluid in the interstitial areas an increase in the blood pressure in the capillary bed the area of the blockage becoming abnormally small more fluid entering the venous capillaries fewer...

What causes water to cross capillary beds from high to low hydrostatic? What is the fluid movement when hydrostatic pressure exceeds colloid osmotic pressure at the arteriolar end of the capillary? What is blood pressure equivalent to? What is some of the fluid that is forced out of capillaries returned to the blood by? What is the outward force that blood exerts on the walls of blood vessels? Which neurotransmitter decreases heart rate, and thus cardiac output and blood pressure?

Starling forces govern the passive exchange of fluid between the capillary beds and the interstitial fluid. For each of the modifications listed below include the following in your answer: a) describe how this change will alter factor(s) of the Starling principle, and b) indicate whether filtration across capillaries into the interstitial fluid will increase or decrease. i) Increasing blood hematocrit levels. ii) Increasing release of norepinephrine from the sympathetic nervous system. iii) Moving from supine (lying horizontally with face and...
