Circulatory System Question
Q: Is it possible to stay awake during cardiac surgery?
A: Yes, it is according to http://www.dailymail.co.uk/health/article-1250507/Eyes-Wide-Open-Patient-open-heart-surgery-awake.html which was posted on February 12th 2010. It says rather then putting the patient to sleep with an anesthesia they gave him an epidural to the neck, numbing his whole body. It is quoted that "Lead surgeon Dr Vivek Jawali, said they had performed more than 600 operations this way since 1999."

Interesting Question About The Lungs
Q: Are the left lung and right lung the same?
A: No, the lung on the left side of your body is divided into two lobes while the lung on your right side is divided into three. The left lung is also slightly smaller, allowing room for your heart.

Respiratory: Vital Capacity
1. My vital capacity is one of the lowest of the boys in the class. I think it is like this because I am the smallest boy in the class giving me a smaller lung capacity.
2. A usual breath can range from 1/2 a litre in a quiet breath to 6 litres for a tall singing base baritone. Our breaths depend on height, weight, posture, parents genes, cellular condition, chemistry, emotions, breathing skill level, thinking processes and more.
3. Regular exhalation is when all the muscles relax to allow air to leave the lungs, while forceful exhalation is when the muscles are relaxing, but we are also using other muscles in our body to make the thoracic cavity smaller. People cannot train the bronchi or alveoli to obtain more air, but can train the muscles that help expand and compress the thoracic cavity to achieve a greater vital capacity.

Interim Report
1. Times when I have felt successful are when I am able to fully comprehend either the notes or tests that we have. Also, when I learned to photocopy sheets for Ms.Phillips is when I feel successful.
2. My work habits in class a quite good. I am usually on task and getting things done, occasionally there are times when I lose focus and begin to get off topic. In the end I am able to get my work done, usually early so I feel like my work habits are good.
3. I have work with Josh on multiple things and I feel that it has enhanced my learning because it gives me another way to look at things when we discuss how to answer certain questions.
4. My goal in biology is to be able to remember all the information I learn this year and be able to use it later on in college and university. To do this I need to really apply myself to my learning.

Biological Molecules & Food Lab Questions
1. Describe a positive result for each of the tests that you performed in the lab.
a) For the simple sugars, if the contents in the testtube have turned into a yellow/orange colour then one has achieved a positive result. For the starches, if the food sample turns black after dropping an iodine solution on it, one has a positive result. Finally, for the fats, if a grease spot occur after rubbing the food sample on the paper, then one has a positive result.
2. Starch molecules are large carbohydrate polymers. Find and post an image of the molecular structure of starch. What are the building blocks that starch molecules are made of?
a) the building blocks of a starch molecule is made up of glucose molecules.
3. Thomas and Josh had interesting results to their simple sugar test - if you are following either of their blogs, look at their picture of their test tubes after they took them out of the hot water bath.
After 2 minutes, only 2 of the test tubes were yellow/orange, and the rest remained blue. They took the two positive test tubes out of the hot water bath and left the others in the hot water bath for 2 more minutes. At the end of the two extra minutes all the test tubes indicated a positive result. Based on your knowledge of carbohydrate molecules, why do you think they got these results?
a) Carbohydrate molecules are made up of glucose molecules, so when the carbohydrates are heated up they break down and become glucose giving a positive result in the simple sugar test.
4. Making connections - Describe the passage of one of your food items through the digestive system, starting with the mouth & ending at the anus. Include the specific enzymes, accessory organ secretions & internal conditions the food/chyme would pass through from start to finish.
a) For a bagel the digestion starts in the mouth with the salivary glands which will produce salivary amylase to break down the starch to maltose. Once the bagel begins to travel down the esophagus through peristalsis, the bagel has now become a food ball called a bolus. It then goes into the stomach, through the cardiac sphincter, where gastric juice turns the bolus into chyme. After the stomach the chyme is sent into the small intestine, through the pyloric sphincter, where the digestion of starch continues, the pancreas excretes out pancreatic amylase which breaks down starches into maltose. After all the starch has turned into maltose the small intestine has an enzyme called maltase to break down the maltose into glucose. It is then absorbed into the body for energy, goes through the large intestine turning into feces, goes into the rectum and is collected and then comes out the anus.
