Answer all of the following questions to the best of your ability in complete sentences in the space below.
1. It’s the first day of spring (give or take three weeks)! Regardless, you run outside to get a breath of fresh air. Describe the path that an inhaled molecule of oxygen would travel starting from the nasal cavity. You can write your answer as a list, a diagram, a flow chart, a paragraph, etc.
2. How does breathing work?
3. How does the respiratory system work to maintain homeostasis in your body? Think deeply and be specific. Include an example if possible.
4. Identify stressors that could affect the respiratory system (ex. exercise). Describe how you think the respiratory system can respond to those stressors.
5. What are other systems of the body that the respiratory system will interact with in order to maintain homeostasis? Identify at least two systems and then describe in detail how each works with the respiratory system.
6. How is the respiratory system related to concepts like diffusion, osmosis and active transport?

HW - 2/27/12
Read about the situation below and answer the questions to the best of your ability. Use your notes and knowledge about diabetes as well as the textbooks as a reference.
James is 16, athletic and has previously been in good health. Recently, he has been feeling tired and gets very thirsty, even though he tries to get a good night’s sleep and drink water during the school day. Even though he’s thirsty all the time he also has to go to the bathroom to urinate more often than previously. Sometimes, his friends even tell him that his breath smells fruity.
1. What do you think is going on with James? Support your opinion with evidence and logical reasoning.
2. James doesn’t understand your diagnosis. Explain to him how his body usually deals with the sugar (glucose) in his blood in order to maintain homeostasis. For example, what happens when he hasn’t eaten in a few hours and it drops?
You can write a paragraph, you can make a flow chart or diagram, or you can create a numbered list of steps to show how his body maintains homeostasis in this case.
3. Now explain how James’ body is different and how he is not currently maintaining homeostasis.
4. Recommend a treatment for James and describe how it is going to return his body to homeostasis.
5. Last, James tells you that his uncle Dan has been experiencing some of the same symptoms that James has along with trouble with his vision and numbness in his extremities (hands and feet). Dan was a man of normal health until he had a foot injury that prevented him from exercising normally. As a result, Dan is overweight.
What do you think is going on with Dan? How is his condition similar to that of James? How is his condition different? Support your opinion with evidence and logical reasoning.

Notes 23 - Diabetes Basics
Diabetes is trouble regulating blood glucose levels because of a lack of insulin or insulin resistance.
Glucose is the sugar that all of our cells rely upon for energy.
Insulin is a hormone that lowers blood glucose levels by making glucose diffuse into cells and causes glycogen to form.
Glucagon is a hormone that raises blood sugar by breaking down glycogen.
Glycogen is used to store sugar in your liver.

Mid-Winter Recess HW - 2/17/12
Your homework for the break involves three parts.
1. What is Diabetes - Part 1: Gain basic information about diabetes by conducting internet research. Your research notes will be checked in class on Monday, February 27th.
Your notes should include a summary of useful information about diabetes such as:
- the different types of diabetes
- the causes of diabetes
- the roles of insulin and glucose
- the symptoms associated with diabetes
- the long-term health problems associated with diabetes
- ON YOUR OWN - how diabetes is related to homeostasis
Useful resources include:
NY Times Health Guide to Diabetes
PubMed Health - Diabetes
2. Complete the Diabetes Basics quiz on Engrade by 8:30am of Monday, Febraury 27th.

HW - 2/15/12
Tonight's homework has 3 partss:
1. Complete CW 67 questions.
Answer all of the following questions to the best of your ability and in complete sentences in the space at the bottom of the page.
1. How could oxygen cross the cell membrane if the concentration of oxygen is lower inside the cell than it is outside the cell?
2. How are facilitated diffusion and active transport related to homeostasis?
3. How is facilitated diffusion different from active transport?
4. Some organisms that normally live in pond water contain water pumps. These pumps continually pump water out of the cell. Describe a situation that would reverse the action of the pump.
5. Farming and watering that is carried out in very dry regions of the world leaves salts that accumulate in the soil as water evaporates. Based on what you know about concentration gradients and transport, why does increasing salinity (or saltiness) of soil have negative effects on plant cells?
6. Summarize – Based on this week, how does cellular transport help maintain homeostasis within a cell?
