My interesting post

1.  Tobacco smoke is harmful to smokers and nonsmokers. Cigarette smoking causes many types of cancer, including cancers of the lung, esophagus, larynx (voice box), mouth, throat, kidney, bladder, pancreas, stomach, and cervix, as well as acute myeloid leukemia. Smoking reduces your lungs' ability to remove germs, dirt and the chemicals you expose yourself to when you smoke. The chemicals that cause cancer get trapped.  The alveoli absorb the oxygen you breathe in and then get rid of the carbon dioxide as you exhale. When the alveoli become damaged, your lungs and heart must work harder to take in oxygen and release carbon dioxide, which leads to chronic lung disease.

    In addition to raising the risk of cancer, smoking also reduced the ability of the lungs to function. In particular, smoking reduces the vital capacity of the lungs, which is the amount of air the lungs can take in. This reduction in vital capacity has several important health effects.

Interim

Hi Mom and Dad!
This is my interim report for the Human Kinetics Coop.

So far, the highlights for me have been: the beep test, the rock climbing trip 


I am the most proud of: my beep test score


The most interesting things I have learned about are: the heart, my respiratory system and how it works. 


An example of when I really pushed myself in SuperFit is: When I did my first beep test, I had to really push myself to beat Ms.Phillips. 


I could make improvements in: class by working harder at times and push my self a little more in super fit. 


I am really looking forward to: Learning more about the human body in biology. 


The Basics - WORK HABITS:

Attendance (classes missed and why) - Missed some classes due to soccer.

Participation in field trips (woo kim, grouse grind, rock climbing) - I went to all except the grouse grind. 

Lates (how many & reasons) - Sometimes because i take long eating at lunch.

Preparedness for class (gym strip &/or supplies) - always

Class time management (are you using your class time to complete your work?  engaged in class discussion? participating? following along? doing your best? or talking too much? ) - I complete all my work, I sometimes get distracted but I try to engage in class discussions. 

Blog assignment completion - (out of 8 assignments) Comments?

Vo2 Max

My vo2 level according to my beep test which was 13 is 57.5 which is excellent for a person my age. I plan to get a higher score on my beep test next time to improve my vo2 max.

Grouse Grind

During the grouse grind i went past my zone 4. I was breathing hard, my body temperature was rising. As I past the half way mark my legs started to feel fatigue and it became much harder to go up. After passing the last quarter my heart was at it highest and my muscles were starting to give up. Also after half i went from a,light jog to walking up the hill. I believe the energy system used during the grind was Aerobic because it was high endurance and my heart rate was increasing. My fat was used as fuel to give my body energy, so I could keep going and than was burnt off as sweat

 and cellular respiration.  

Heart Disection

external observation:
The heart was a lot bloodier than i thought it would be. It made me sick looking at the heart and how real it was. It was bigger than i expected and didn't really look like a heart but more like a piece of meat.

internal observation:
I didnt see the heart in person but looking at the pictures i can see that the inside is a lot bloodier and lighter than it is on the outside. The heart looks like it will be soft and mushy from the inside.

 QUESTIONS:

1) The most surprising thing for me was how bloody and real the heart was, i felt sick everytime i would look at it. I was suprised because i didnt expect to feel that way. 
2) the atria only has one job to collect and squeeze blood into the ventricles. The ventricles are larger because they need to contract the blood.
3) The left ventricle pumps blood to the entire body while the right only pumps blood to the lungs. 
4) The left AV Valves (mitral) function is to close when the left ventricle contracts to prevent back flow of the blood from the left atrium and right AV valves(tricuspid) function is to close when the right ventricle contracts. Then the blood from the ventricles can go out of the heart and into the blood vessels. Mitral and tricuspid valves open when the ventricles relax and let blood enter the ventricles from the atria.
