The three routes by which blood-borne substances can pass through a capillary wall into the tissue. Introduction: Materials such as nutrients, waste, and hormones must pass through the walls of the vessels between the blood and the tissue fluids to serve any purpose. The wall is too dense for sufficient movement of chemicals between the bloodstream and tissue fluid in almost all the larger vessels.

Illuminate the Truth Capillaries Highlight the word or phrase that makes cach of the following statements true. 1. Capillaries (are)(are not) evenly distributed throughout the body. 2. The majority of the capillaries in skeletal muscles are (constantly filled with blood)(shut down during periods of rest). 3. Capillaries (take up)(release) wastes, such as carbon dioxide and ammonia. 4. Water (flows into)(moves into and out of) capillaries. 5. In diffusion, substances move from areas of (greater)(lesser) to (greater)(lesser) concentration. 6. The concentration of oxygen within capillaries is (greater than)(less than) the concentration of oxygen in the surrounding tissue fluid; therefore, oxygen diffuses (into)(out of) the capillaries. 7. (Osmosis) (Filtration) occurs close to the arterial side of the capillary bed, while (colloid osmotic pressure)(diffusion) operates toward the venous side. 8. Of all the fluid filtered at the arterial end of the capillary bed. about (85%)(15%) is…

A 50-year-old male patient arrives in the emergency department complaining of severe chest pain. He is taken to the cardiac cath lab for a coronary angiogram and left ventriculogram. The cardiologist discovers a lesion in the left main coronary artery branch and orders an immediate CABG. 1. Why does the location of this lesion make it more dangerous than lesions in other locations? 2. What does the acronym CABG stand for? 3. Assuming that the CABG is successful, what is the patient's postoperative prognosis? 4. Could the cardiologist perform an angioplasty to repair the lesion?
