Description Wk 2 Summative Assessment: Wastewater Treatment Lab Report In science, reporting what has been done in a laboratory setting is incredibly important for communicating, replicating, and validating findings. However, writing scientific reports can be a little overwhelming. There are a set of agreed upon components that the scientific community requires when reporting scientific research.

Description This document has hints and comments for some of the Short Answer questions.  This should allow you to see the general types of things I am looking for.  You can use this document to  check your answers.  If you are checking off the items in the question, you are off to a great  start.    Organize your answer, write well, and present it in such a way that your information is easy to  find.  Your answers also need to be precise and concise.  Some students add so much information  (some of it relevant and some of it not) that it looks like they are throwing everything against the  wall and hoping something sticks.  This tells me you haven’t really thought about your response,  and that is a no-no.   Remember whenever you see “homeostasis,” flow-down-gradients,” or “cell-to-cell signaling,”  think about our core concept and the bulleted items.  Then, apply that concept to the specific  question.  Finally, remember this is physiology so think about the function or “how” something occurs.   1. Explain the Frank-Starling law of the heart. Make sure to give a short, explanation of the Frank-Starling law and the role of stretch on  the cardiac contractile tissue has on the force of contraction.   You should then explain  how this property allows for the matching of venous return and stroke volume.  Some  important topics to consider as you answer this question are end-diastolic-volume (EDV),  end-systolic-volume (ESV), venous return, preload, afterload, and Starling curves. 2. Compare excitation-contraction coupling and relaxation in cardiac and skeletal  muscles. Compare questions need to include similarities and differences.  One way to do this is to  start with how the ECC is similar in the two types of muscles (the roles of calcium and  ATP ?-> ADP+P for example).  End the paragraph with a sentence stating in general  how they differ.  Then spend a paragraph on discussing the specifics of how skeletal  muscle is different and a paragraph outlining how the cardiac muscle is different.  Some  important topics to consider as you answer this question are action potential generation,  sarcoplasmic reticulum, calcium, troponin, tropomyosin, myosin, actin, crossbridge  formation, Calcium ATPase (CaATPase), Sodium-Calcium-Exchanger (NCX), t-tubules.  3. Compare the structure and function of skeletal, cardiac, and smooth muscles Compare questions need to include similarities and differences.  What do all three muscle  types have in common.  How are skeletal and cardiac muscle similar but different from  smooth muscle?  How are smooth muscle and cardiac muscle similar but different from skeletal muscle?  Some topics to consider include summation, gradation, speed of contraction, fatigue, sarcomeres,  4. Compare the action potentials of contractile cardiac muscle, autorhythmic cardiac  muscle and skeletal muscle.     Compare questions need to include similarities and differences.    What do all of these  types of action potentials have in common?   How is an autorhythmic cardiac action  potential different from skeletal and cardiac contractile action potentials?  How do  skeletal and cardiac contractile action potentials differ?  Some important topics to  consider as you answer this question are resting membrane potential, pacemaker  potential, If  channels, sodium voltage-gated channels, potassium voltage-gated channels,  calcium voltage-gated channels, depolarization, repolarization, hyperpolarization,  pacemaker. 5. Describe the conductions of electrical signals through the heart. While you may learn this as a sequenced list, you must (as in you will lose points if you  don’t) answer this question with a narrative of the structures involved in initiating and  coordinating the contraction of the heart.  You need to include the function of each  structure.  The topics you should consider as you answer this question include pacemaker  cells, the sinoatrial node, atrioventricular node, internodal pathway, bundle of His, bundle  branches, Purkinje fibers, first degree block, second degree block, and third degree block. 6. Describe the parts of the electrocardiogram (ECG) and explain how these electrical  events are related to the mechanical events of the cardiac cycle. The Wigger’s diagram is a good reference to use when preparing your answer to this
