10) A patient has an 80% blockage of his left anterior descending coronary artery. Describe what occurs in terms of myocardial oxygen supply and demand if his sympathetic nervous system is stimulated.

PART A QUESTIONS:
Choose 1 variable from the list below:
low blood calcium levels
low blood sodium levels
Then, perform research to answer the following questions about the variable you chose.
A) Determine the negative feedback cycle by which the variable you chose is restored to normal blood levels. List the 5 components of the cycle in order, like this:
1. Variable = choose 1 from list above
2. sensor/receptor =
3. control center =
4. effector(s) =
5. physiological response(s) =
B) Name at least 3 organ systems involved in regulating the variable that you chose and describe HOW each system is involved. Hint: use Chapter 9 covering the endocrine system as one of your references. NOTE: this question asks for the names & descriptions of 3 SYSTEMS (ex. cardiovascular system), not individual organs (ex. heart)
. II. A&P: The human body is capable of performing a variety of functions due to its complex structural organization (anatomy). Choose 2 human organs, ex. stomach, eye, triceps muscle, heart, etc. For each organ that you chose:
A) List 5 words which describe the organ's anatomy ~ such as shape, size, structure, color, location, texture, tissue composition and organization, solid/hollow, hard/soft ~ these are examples of anatomical (structural) descriptors; words that describe anatomy are usually adjectives
B) List at least 2 functions of each organ that you chose. Physiology includes what the organ does, why the body needs it, and the jobs achieved by that organ related to serving the body as a whole in order to maintain health ~ such as ability to contract, digest, secrete, communicate, regulate, transport, clean, protect, etc. ~ functions are usually verbs (action words)
Part B: Biochemistry (Ch. 2) (20 points)
INTRODUCTION: Use your textbook (Ch. 2) and reliable websites to answer the following question related to biochemistry in the human body. Write your answers in complete sentences with correct spelling and grammar. Provide definitions for any scientific terms included in your answer.
PART B FORMAT EXAMPLE: For each numbered item, write the number, the topic of the question (in UPPER CASE font) and your answer(s) to the questions. Follow the example below.
1. ELEMENTS
A answer
B. answer
2. TRACE ELEMENTS
Write TRUE or FALSE and justify your answer
3. etc.
PART B QUESTIONS:
1) ELEMENTS
A. Name the 5 most abundant elements in the human body, in order of most abundant to least.
B. Create a mnemonic to remember this information. HINT: refer to this website to learn about mnemonics: https://literaryterms.net/mnemonic/
2) TRACE ELEMENTS TRUE or FALSE: Trace elements are not required for human life. Justify your response by defining what a “trace element” is and discussing 2 examples that support your answer.
3) CHEMICAL EQUATION
A. Balance this equation: C6H12O6 + O2 → CO2 + H2O + ATP
B. Which chemicals are the reactants (substrates)? Name them.
C. Which are the products? Name them.
D. What is the name of this chemical reaction?
E. Cells must be able to perform this chemical reaction TO STAY ALIVE. Why is this reaction critical for cell life?
F. This reaction produces the most common cellular waste product in the body – carbon dioxide. High levels of carbon dioxide cause blood pH to fall, making plasma acidic – this can lead to metabolic problems. How does the body get rid of CO2?.
4) SOLUTIONS Plasma is the liquid component of blood (cells have been removed). It is mostly made of water plus solutes. It is one of many aqueous solutions in the human body.
A. What is the solvent in plasma?
B. Name at least 5 solutes in plasma.
C. In addition to blood (plasma), there are other water-based solutions present inside the human body or secreted/excreted from the body which are water-based. Name 3 other aqueous solutions that the human body produces.

Shaun has pneumonia. Pneumonia is a lung infection that causes the alveoli to accumulate pus and/or fluid. How does this effect the diffusion of oxygen into the blood?
The accumulation of pus and/or fluid will thicken the respiratory membrane does not affect diffusion nor oxygen uptake into the blood |
The accumulation of pus and/or fluid will thicken the respiratory membrane and slow down the diffusion rate. This would increase the amount of oxygen taken up by the blood. |
The accumulation of pus and/or fluid will thicken the respiratory membrane and slow down the diffusion rate. This would decrease the amount of oxygen taken up by the blood. |
The accumulation of pus and/or fluid will damage the diffusion membrane, increasing diffusion and the amount of oxygen taken up by the blood. |

Consider the brain areas and connections pictured in the simplified basal ganglia circuit. Parkinson’s disease results from the degeneration of dopamine neurons in the substantia nigra pars compacta (SNc). Dopamine can inhibit or excite neurons in the putamen, a sub-division of the striatum. Describe how this damage causes a chain of effects on activity in other basal ganglia areas and the structures they ultimately output to, and how this results in hypokinesia (reduced movements) in two different ways. Make sure to refer differentially to the ‘direct’ and ‘indirect’ pathways.
