Which of the following is not one of the aspects of human experience that are explored through phenomenological study?

Use the pull-down menus to insert the best terminology that makes the following sentences true: There are many different kinds of medications that can be prescribed to treat hypertension.  For example, [blank1] work specifically at the heart, decrease the contractile force produced by that organ, and ultimately decrease blood pressure by lowering [blank2].  Alternatively, [blank3] target the kidneys, increase urine production, and ultimately decrease blood pressure by lowering [blank4].

Wade and his wife have been diligently following the CDC’s “social distancing” recommendations during the COVID-19 pandemic.  But … at this point, they are climbing the walls, are sick and tired of their kids always complaining about being SOOOOO BORED, and they desperately need some exercise.  So, they decide to go for a brisk walk in their neighborhood, which is nestled in the hills just west of Atascadero.  As they begin their walk, their blood pressure is too low to support their elevated level of activity, especially as they start to follow their street up a steep, nearby hill.   In the space provided below, describe the steps of the negative feedback loop that Wade’s body will use to solve this problem and return him to homeostasis.  Make sure you focus on how the majority of his arterioles must change to solve this problem. You may list the generic steps and give a brief description, like this: 1) Stimulus – type your description 2) Sensor – type your description etc., etc., until you arrive at the desired Response Make sure to list all the generic steps of a feedback loop for this class AND describe the specific physiological details for each of those steps EXACTLY as if you were drawing a feedback loop diagram.  Provide as much physiological detail as possible at each step (e.g., effector cells, receptor types, signal molecules, the step-by-step “action” that fixes the problem, etc.).

Lily is a pro at social distancing and a pretty-darned good amateur mixologist as well.  She mixes up her favorite cocktail and decides to enjoy it on her balcony, since it is a B-E-A-utiful summer evening on the Central Coast.  By about mid-cocktail … OH NO … a huge bee begins to dive bomb her and she is terrified, because she is highly allergic to bee stings.  She runs back into her house and slams the patio door shut just in time to keep the bee out.  Her heart is pounding in her chest and her blood pressure is greatly elevated.  However, now that she is safe inside, cocktail still in hand, she is safe to rest and resume happy hour. In the space provided below, describe the steps of the negative feedback loop that her body will use to solve this problem and return her blood pressure to homeostatic levels.  Make sure you focus on how her heart rate must change to solve this problem. You may list the generic steps and give a brief description, like this: 1) Stimulus – type your description 2) Sensor – type your description etc., etc., until you arrive at the desired Response Make sure to list all the generic steps of a feedback loop for this class AND describe the specific physiological details for each of those steps EXACTLY as if you were drawing a feedback loop diagram.  Provide as much physiological detail as possible at each step (e.g., effector cells, receptor types, signal molecules, the step-by-step “action” that fixes the problem, etc.).

Use the pull-down menus to insert the best vocabulary words into he blanks that make the following sentences true: During the inflammatory response, some immune cells will release [blank1] when stimulated by a pathogen, which dilates nearby blood vessels.  This increases perfusion to the infected tissue, which allows more filtration and phagocytes to enter the infected area by a process called [blank2]. As those phagocytes begin to destroy the pathogen, they will release [blank3], which helps to activate other parts of the inflammatory response (e.g., complement proteins).  These phagocytes also often release [blank4] which can reset the temperature set-point in the hypothalamus to a higher value.

DID YOU REMEMBER TO PICK UP YOUR LAPTOP OR EXTERNAL WEBCAM AND SLOWLY (10-15 SECONDS TOTAL) MAKE SEVERAL SCANS WITH THAT WEBCAM ACROSS YOUR WORK ENVIRONMENT TO PROVE YOU DON’T HAVE ANY NOTES OR ELECTRONIC DEVICES CLOSE BY?

Study this diagram carefully.  It shows three blood vessels from top to bottom each with a different radius (r).  If you would rather think about the diameter of these vessels, then remember that diameter = 2(radius).  The delta-P and direction of blood flow are also shown.  Assume that all vessels are the same length and blood flowing through each has exactly the same composition. Use this information to answer the following questions below using the pull-down menus:

These immune cells are primarily involved in generating allergic reactions in the body.

Use the drop-down menus to select the best vocabulary terms that complete the following sentences: There is currently no way to preemptively create [blank1] to COVID-19 in humans, because there is no vaccine.  However, it may be possible to establish [blank2] in some patients if they receive a transfer of immunoglobulins from individuals that have already recovered from the disease.

Vanessa went to the gym at least 4 days per week before the COVID-19 pandemic, but now she is forced to work out from home.  All she has are some old kickboxing workout DVDs around the house, so those will need to suffice.  As she completes here workout and flops down on the couch, her blood pressure is too high for her new, lower activity state. In the space provided below, describe the steps of the negative feedback loop that her body will use to solve this problem and return her to homeostasis.  Make sure you focus on how the majority of her arterioles must change to solve this problem. You may list the generic steps and give a brief description, like this: 1) Stimulus – type your description 2) Sensor – type your description etc., etc., until you arrive at the desired Response Make sure to list all the generic steps of a feedback loop for this class AND describe the specific physiological details for each of those steps EXACTLY as if you were drawing a feedback loop diagram.  Provide as much physiological detail as possible at each step (e.g., effector cells, receptor types, signal molecules, the step-by-step “action” that fixes the problem, etc.).
