Textbook Question
Chapter 4, Problem 6AWK
By definition, an organ is a structure composed of two or more tissue types that perform a specific function. Performance of that function often requires coordination among many cells. Why is it so important that cardiac muscle cells of the heart be synchronized (coordinated) so that they beat nearly all at once?

Human body system is a powerful machine that works all the time. To maintain the system, homeostasis should function regularly. Give TWO (2) examples and discuss the factors that give effect to this selfregulating process.
Whether the statement "Stem cells, being stem cells, are by definition the same in all tissues" is true or false.
The body is made up of more than 200 different cell types, from small white blood cells to branching neurons more than 10X the size. Why is there such variation in size and shape?

- Which of the following is a tissue? endocrine cardiopulmonary muscle brainarrow_forwardwhen we use interventions to lessen the symptoms of inflammation, such as ice for swelling, and antipyretics for fever, wouldn't that slow the healing process? For instance, ice reduces swelling through vasoconstriction, however, the site of injury requires increased blood flow for tissue repair. Therefore, vasoconstriction would halt the healing process and prolong injury. Would it be more advantageous then to let our bodies do their job and just deal with the symptoms?arrow_forwardNerve impulses are sent to slow the heart's rate of contraction. The nerve fibers sending these signals will most likely belong to which division of the nervous system?

- One way to characterise biological tissue is to send a small electrical current through the tissue and measure the opposition to flow of that current through the tissue. In humans, the resistivity of fat is considerably greater than for muscle, which in turn is considerably greater than for blood and other body fluids. This can be used to analyse body composition, in particular, to estimate body fat percentage. (a) Using a simple model of fat versus non-fat tissue, draw a circuit diagram to represent the possible flows of current through the tissue. (b) Why would the analysis of body composition need to take into account the height and weight of the person?
