Honorlock has live proctors available on standby working 24/7/365 to address students who commit academic misconduct. Honorlock’s technology will alert our proctors to such sessions.

Would stroke volume increase or decrease if there is an increase in sympathetic nervous system stimulation?

A.  Calculate stroke volume if end diastolic volume (EDV) is 135 ml/beat and end systolic volume (ESV) is 65 ml/beat. Show your work. Remember to include the units in your answers! Bold or highlight your final answer. B.  Using the necessary numbers from question A, calculate cardiac output (CO) if HR = 65 bpm. Show your work. Remember to include the units in your answers!  Bold or highlight your final answer. 

During the four phases listed below, state whether the AV and semilunar valves are open or closed.   Please include the letters with your answers.  Example:  If the answer to T is spleen, the type T = Spleen.  Although your answers should only be “Open” or “Closed” for the answers to these.    Picture2 – HEART – VALVES – TABLE -.png 

List – in order of occurrence – the three (3) steps of hemostasis.

Due Date/Time: 10:35 AM Wednesday February 5, 2025.  Maximum Time Limit = 65 Minutes (in one sitting).  Must be taken in one 65-minute sitting/session.  IF YOU NEED TO USE SCRAP PAPER, ASK FOR SOME.   Be sure that you type all your answers and any work into the exam, too, please.   IF YOU NEED TO USE A CALCULATOR, IT MUST BE A REGULAR CALCULATOR (HAND-HELD).  PHONES AREN’T PERMITTED.   REMINDERS: Exams, tests, and quizzes are closed books, closed notes, closed slides, closed assignments, and taken individually.  No additional devices allowed other than the one (1) being used for the exam/test/quiz. Only the test/exam/quiz screen should be open.  A simple, basic calculator can be used (not phones).  No other windows, websites, programs are permitted. 

Match the process with its descriptions/components.

Why would stroke volume increase if the heart rate slows down?  Explain in 1-3 sentences, please.

A wheel is pivoted at its center. It has a radius R and mass M. A piece of clay of mass m and speed v is about to strike it at the bottom edge, tangentially, as shown, and sticks to it. What is the angular velocity of the system right after the collision?                                                      

A ball is launched from the top of a building that is 20 meters tall with an initial speed v0= 30 m/s{“version”:”1.1″,”math”:”v0= 30 m/s”} and at a non-zero angle θ{“version”:”1.1″,”math”:”θ”} below the horizontal. If y=0 at the ground, what is the correct equation for y as a function of time?
