- SCIENCE, TECHNOLOGY, AND SOCIETY A person with kidney disease lives 10 to 15 years longer with a kidney transplant than on continued dialysis. However, in the United States many individuals have difficulty being accepted by a transplant program because they do not have adequate insurance or other resources. The immunosuppressive drugs and other medications required after the surgery are also very expensive, costing about 2500 per month. Should economic status be a deciding factor about whether a person lives or dies? or about quality of life?arrow_forwardTest Your Understanding 17 EVOLUTION LINK Although the kidney is basically similar in all vertebrates, its structure and function vary somewhat among vertebrate taxa.

Your flowchart should include these concepts and details: location in the nephron where the reactions occur, the types of substances moving into or out of the nephron, vocabulary and terminology that allow you to demonstrate your understanding. Ask yourself these big questions as a way to monitor and improve your work: Is the information I have presented a complete representation of my learning? Is the information I have presented correct?

- Project Controlling Red Blood Cell Loss During Surgery A typical volume of blood in the human body is about 5 L. A certain percentage of that volume (called the hematocrit) consists of red blood cells (RBCs); typically the hematocrit is about 45% in males. Suppose that a surgery takes four hours and a male patient bleeds 2 L of blood. During surgery the patient's blood volume is maintained at 5 L by injection of saline solution, which mixes quickly with the blood but dilutes it so that the hematocrit decreases as time passes. 1. Assuming that the rate of RBC loss is proportional to the concentration of RBCs, determine the patient's concentration of RBCs by the end of the operation. 2. A procedure called acute normovolemic hemodilution (ANH) has been developed to minimize RBC loss during surgery. In this procedure blood is extracted from the patient before the operation and replaced with saline solution. This dilutes the patient's blood, resulting in fewer RBCs being lost during the…arrow_forward1.
