Ch 22: The Respiratory System 5-2 Objectives Functional Anatomy of the Respiratory System 1. Identify the organs forming the respiratory passageway(s) in descending order until the alveoli are reached. 2. Describe the location‚ structure‚ and function of each of the following: nose‚ paranasal sinuses‚ pharynx‚ and larynx. 3. List and describe several protective mechanisms of the respiratory system. 4. Distinguish between conducting and respiratory zone structures. 5

Homeostasis: An Analogy Reginald Robinson BIO1000 Capella University The homeostatic mechanism that regulates body temperature is called hypothalamus. It senses when your body’s temperature is too hot or cold. When your body is too hot‚ the hypothalamus senses that a change needs to be made so to reverse the heating process‚ thus reducing the amount of blood that is being sent to that area. This same action will cool the body and return it to a normal temperature. The ways in which

Name and define the ten life processes that distinguish living from non-living things. 5. Specify the five environmental needs required for life. 6. Define the term homeostasis‚ and name the manner in which homeostatic mechanisms are regulated. Then provide an example of a homeostatic mechanism in humans‚ and explain it fully‚ by providing a diagram followed by a complete essay explanation. 7. Demonstrate what is meant by "anatomical position". 8. Define various directional terms (i.e.

these changes are referred to as stimuli as they are what stimulate the change in internal conditions. The body detects these changes with receptors which communicate signals to the hypothalamus in the brain which is the control centre for this homeostatic system. The hypothalamus responds to these signals by causing an effector to bring about an appropriate response which will keep the internal environment of an organism constant in the changing external environment. An example of homeostasis is

Use variety pH homeostatic mechanism that involve restricting proton entry by cytoplasmic membrane and purging of protons and their effect by cytoplasm. pH homeostatic mechanisms The cell membrane is highly impermeable to protons Membrane channel have a reduced pore size. Protein influx inhibited by chemiosmotic gradient Excess proton pumped out of the cell Cytoplasmic buffering helps to maintain

this‚ it must maintain a certain blood pressure within the body to overcome gravity and orthostatic changes. If the body did not keep a certain pressure‚ distal cells and organs would not be able to receive a constant blood supply and cause a homeostatic imbalance. This experiment will show the possible changes in blood pressure due to gravity and orthostatic changes‚ but first‚ what is blood pressure and why is it important? Blood pressure is the force exerted by blood against a unit area of the blood

paid a formal salary. Through out her life she published many papers and help to create the modern world of medicine. She started off with co-developing two of the first drugs treatments for leukemia. She soon then developed a drug for treating gout. Years after that she developed a mainstay drug treatment for HIV. In 1988 Trudy was awarded the Nobel Prize in physiology/medicine.

system falls out of balance. In the worst cases‚ it fails completely. With the simulation of the fictional patient‚ if the body did not stay at a homeostatic state‚ then the patient either gained weight or lost weight. In both cases‚ the patient died. No matter the age or size of the patient‚ it was always possible for the patient to reach a homeostatic state. To reach this state‚ the patient either had to eat less or do more physical activity. Just by taking some basic steps‚ the body helped maintain
