The net filtration across relaxed skeletal muscle capillaries is about 0.005 ml/min per 100 g of tissue. assume the following values: the density of muscle is 1.08 g/cm3; the length of the capillaries is 500 μm and their cross-sectional density is 250 capillaries/mm2. their average radius is 4 μm. pressure at the arteriolar end of the capillary is 40 mm hg and it decays linearly to 15 mm hg at the venule end. the oncotic pressure of plasma is 25 mm hg. interstitial fluid pressure in relaxed muscle is -1 mm hg and intersitial fluid oncotic pressure is 5 mm hg

a. calculate the surface area of the capillaries per 100 g of muscle. (hint: calculate the mass of muscle 250 mm2 in cross-section and 500 um long)
b. does the capillary filter fluid along its entire length, or does it reabsorb fluid at the venule end? support your answer with calculations based on the givern information.

Which of these is not an intrinsic muscle of the foot? a. quadratus plantae b. abductor digiti minimi c. flexor digitorum brevis d. flexor digitorum longus e. abductor hallucis

A10-year-old girl suffered from a rare malignancy in her brain and around her spinal cord. she had surgery, and most of the tumor mass was removed, but residual tumor remained in the brain and around the spinal cord. the girl's doctors informed her parents that chemotherapy and radiation were possible treatment options but could cause serious problems such as sepsis, a permanent loss of iq and stature, and even death. the parents wished to proceed with the therapy. while their child was undergoing aggressive chemotherapy and radiation, the parents did independent research and read of several drugs being administered for cancer in other states that were unapproved by the federal drug administration (fda) and were illegal in their home state but were touted by physicians using them as miracle cures." furthermore, one of the girl's doctors released the girl's medical records to another physician to get a "second opinion" without informing the parents. this particular physician is a member of the same country club as the parents. he happens to share facts from the medical records with other members who end up telling the girl's parents. the couple sued their child's physician for failure to disclose alternative treatments, thus depriving them of informed consent. the couples also sued the child's physician for sharing their daughter's records in violation of the girl's privacy. how should the court rule in both cases? did the child's physician involved follow the law? did he act ethically in either situation? explain your answer. under the doctrine of informed consent, should a physician be responsible for informing patients of all treatment options, even if some of the treatments are illegal or not yet proven effective?
