However, the ME must also be a physiologist because understanding structures normally function in the body is critical to determining why a person died. For example, observing that a bullet made a hole in the heart is an anatomical observation, but realizing that the person died because the heart could no longer circulate blood is a physiological observation. An ME must be both an anatomist and a physiologist. Reference: Page 12, Anatomical Terminology Difficulty: Medium 91) Identify and briefly define the six important life processes of the human body described in Chapter One. Answer: Metabolism is the sum of all chemical processes that occur in the body. Responsiveness is the ability to detect and respond to environmental changes. Movement is the motion of the body or its parts. Growth is an increase in the size and/or number of cells. Differentiation is the development of specialized from unspecialized cells. Reproduction is the formation of new cells or a new individual. Reference: Page 5, Characteristics of the Living Human Organism Difficulty: Medium 92) Define the term homeostasis. Identify the components of a typical feedback loop, and describe the role of each. Answer: Homeostasis is a condition of equilibrium in the body's internal environment produced by the interplay of all the body's regulatory processes. Homeostasis is regulated by feedback loops, which typically consist of a receptor, a control center, and an effector. The receptor monitors changes (stimuli) in controlled conditions, and sends this information to the control center. The control center compares this input with other information from other receptors, and notifies and effector to make an appropriate change. The effector makes the appropriate response, as dictated by the control center. Reference: Page 8, Control of Homeostasis Difficulty: Medium 93) Explain how a positive feedback loop differs from a negative feedback loop. Answer: In a positive feedback loop, the response of the effector enhances or amplifies the original stimulus, that is, the condition is moved further away from homeostasis. In a negative feedback loop, the response of the effector is the opposite of the original stress, and tends to move the controlled condition back toward homeostasis.

Which is most often called the body's "internal environment?" Answer: Intracellular fluid (ICF) is the fluid within cells. Extracellular fluid (ECF) is the fluid outside of cells. Plasma is the ECF within blood vessels. Interstitial fluid is the fluid surrounding cells, and is considered the internal environment. Reference: Page 5, Characteristics of the Living Human Organism Difficulty: Medium 95) Osmometer cells in the brain sense and increase in the concentration of plasma. This information is sent to the hypothalamus, which notifies the pituitary gland to release the hormone ADH. ADH causes the kidney to save water, which lowers the concentration of the plasma. Identify the elements of a feedback loop in this scenario. Is this a positive or a negative feedback loop? Explain your answer. Answer: The controlled condition is plasma concentration, and increased plasma concentration is the stimulus. Osmometer cells are the receptors because they sense the increased concentration. The hypothalamus is the control center, which receives the input from the receptors and notifies the effector of the appropriate response. The pituitary gland and the kidneys act as effectors, since both are required to carry out the response. This is a negative feedback loop because the original stimulus (increased plasma concentration) is reversed. Reference: Page 8, Control of Homeostasis Difficulty: Hard 96) Consider the roles of two hormones involved in regulation of the concentration of calcium ions in the blood. Parathyroid hormone increases the concentration of calcium ions in the blood, but calcitonin decreases the concentration. Maintenance of calcium ion homeostasis is critical to neurological, cardiac and skeletal muscle function. Based on this information predict what type of feedback mechanism would respond to restore calcium balance if a teenager took a dare and ate 100 antacid tablets made of a calcium compound in 10 minutes. Explain the answer in terms of the components of a feedback loop and whether the body would respond to this situation with a positive or a negative feedback loop. Answer: A person eating 1oo antacid tablets in 10 minutes would cause an increase in blood calcium concentration. That increase would be the stimulus. Since calcium ion homeostasis is so important, the body probably has a receptor that detects changes. That receptor would send signals to the gland (or glands) that produce hormones regulating calcium balance. Since the blood calcium level is too high, the body needs to react to lower the blood calcium. This would be a negative feedback loop and would need to use calcitonin. The body might also send signals to block the action of parathyroid hormone because the calcium levels are already too high. There must be a way for the body to get rid of the extra calcium in the blood. Two possibilities are putting more calcium into the bones or putting more calcium out in urine or feces. The cells that put calcium into the bone or release it into the urine or feces would be the effectors in the case described here.

The physician tells the family that the patient’s hypogastric pain may be associated with several conditions and further tests must be conducted. The doctor wants to have some medical imaging tests done, but is concerned because the patient is of reproductive age. When the doctor leaves, the family asks the nurse what the hypogastric region is, what kinds of tests the doctor wants to do, and why it matters if the patient is pregnant. Answer the family’s questions in terms that someone with a middle school education could understand. Answer: The hypogastric region is basically the pelvic region. The nurse could show the general location of the region with a simple diagram or by pointing to the area on the patient. The nurse should tell the family that the urinary bladder and uterus are in that location. The doctor could order several different tests, but because the patient is of reproductive age will probably order one that will not harm a fetus. X-rays can cause birth defects. A safer alternative is to use ultrasound, which will help the doctor determine if there are any unusual changes in the patient’s bladder or uterus. Reference: Page 21, Medical Imaging Difficulty: Medium 98) One of the members of your study group is insisting that a feedback loop is a positive feedback loop because it is "doing good for the body." What is wrong, if anything, with this student's thinking? Answer: This student is confusing the terms positive and negative with good and bad. When describing feedback loops, the terms positive and negative are used in a more quantitative way to describe whether the effects of a loop amplify (increase) or reverse (decrease) a change in a controlled condition. Reference: Page 8, Control of Homeostasis Difficulty: Medium 99) Mr. Barry is experiencing pain in his left hypochondriac and left lumbar regions. He has just been admitted to the emergency room following a construction accident in which he was pulled from beneath the rubble of a collapsed wall. One intern yells, "Get him to X-Ray now!" Yet another intern orders him to CT scanning. What would each intern hope to determine from the procedure ordered? Answer: X-rays (radiography) will give good clear indications of broken bones (such as ribs), while a CT scan would give a better indication of soft organ damage (such as a ruptured spleen).
