colon cancer video

I found the colon cancer video very interesting to watch. not all of it was something you would want to watch but it was something new to see and a new way to learn something we haven't learned yet. I was surprised to see they put this video online and wanted people to see the surgery take place live. some of the parts mentioned in the video we have learned about in class and I had recognized. I learned that this is the way that colon cancer is removed.

circulatory system reveiw

- left and right atria top of the heart 
left and right ventricle bottom of the heart
- atriums trnasfer blood to the ventricles
- left ventricle pumps blood to the body
- right ventricle pumps blood to the left side
- aorta taked blood to body 
-

The central organ of the cardiovascular system is the heart. This is a hollow, muscular organ that contracts at regular intervals, forcing blood through the circulatory system.

2. The heart is cone-shaped, about the size of a fist, and is located in the centre of the thorax, between the lungs, directly behind the sternum (breastbone). The heart is tilted so that the base is tilted to the left.

3. The walls of the heart are made up of three layers of tissue:

a) The outer and inner layers are epithelial tissue.
b) The middle layer, comprising the cardiac muscle of

the heart itself, is called the myocardium.

4. For obvious reasons, the cardiac muscle is not under the conscious control of the nervous system, and can generate its own electrical rhythm (myogenic). For the same reasons, cardiac muscle cannot respire anaerobically and so the muscle cannot get tired (or develop cramp!)

5. Cardiac muscle has a rich supply of blood, which ensures
that it gets plenty of oxygen. This is brought to the heart
through the
coronary artery. Since the heart relies on
aerobic respiration to supply its energy needs, cardiac muscle cells are richly supplied with mitochondria. 


. The heart can be thought of as two pumps sitting side by side – each of which has an upper atrium and a lower ventricle a total of 4 chambers. It functions as two pumps inside one.

2. The right side of the heart pumps ‘deoxygenated blood’ (actually, blood low in oxygen) from the body into the lungs, where gas exchange takes place. In that process, carbon dioxide is lost to the air and oxygen is absorbed. This oxygen is almost all carried by the Red Blood Cells (RBC’s).

3. The left side of the heart pumps oxygenated blood from the lungs to the rest of the body.
4. The heart is enclosed in a protective membrane-like sac called the
pericardium, which surrounds

the heart and secretes a fluid that reduces friction as the heart beats.

5. The atria (upper chambers) of the heart receive blood coming into the heart. Then have thin walls, so allowing them to be filled easily. They pump the blood into the ventricles (lower chambers), thus filling them.

6. The ventricles pump blood out of the heart and the left ventricle has the thickest walls of the heart because it has to do most of the work to pump blood to all parts of the body. This is where the blood has the highest pressure.

7. Vertically dividing the two sides of the heart is a wall, known as the septum. The septum prevents the mixing of oxygenated (left side) and deoxygenated (right side) blood.

8. It also carries electrical signals instructing the ventricles when to contract. These impulses pass down specially-modified muscle cells (Purkinje fibres), collectively known as the Bundle of His

respitory lab

clear lime water
bubbles during 

part a: we used limewater to airate the test tubes , after we saw that test tube c turned whiteish grey color and testube a hada. few bubbles.
part b: distilled water into 2 beakers and one airated and one blew straw for 5 mins, after we used universal indicators beaker c was supose to turn green but our beaker had left over resadue so the color didnt come out right and beaker d turned yellow color and that was acidic. 
part c: the breath they took in 1 min and they took in 30 seconds. the results were: 
one minute: 28,25,18
thirty seconds into a paper bag: 10,14,18

joints

a wrist sprain is common for all sorts of athletes. as you slip and are about to fall you automatically stick your hand out to break your fall, as the force of the fall bends your hand back toward your forearm. this can stretch the ligaments that connect the wrist and hand bones a little to far. it results in a tiny sprain or complete break!






fittness testing second time

when we did our fitness testing for the second time for the beep test I did not get exactly where I wanted to but the rest I improved on for plank we got to 1 min 45seconds and sit and reach was 6. I hope next time it improves even more.

excersize science fitness goal

In exercise science we each did a series of tests that we made up in groups. and recorded the results we got from those tests. the next time we do that testing I wish to do twice as good as I did the first time and reach my goal and get better.

lung inflation

We made a model of what lung inflation would look like and the orange balloon on the bottom is the diaphragm which when goes down fills the lungs with air and when is back it takes out the air from the lungs.

crash course video

The Circulatory and Respiratory system are connected in many ways. They work together by inhaling and exhaling. The heart pumps blood into the lungs where blood is oxygenated. Then the blood is returned to heart and oxy blood is circulated to the body. Also, the respiratory system performs a gas exchange that releases CO2 from the body and brings in O2.
 Something interesting that i learned from the video is that, Simple diffusion is where some animals can take in oxygen without lungs but through wet membranes.

Interm report

For my interim report I think I deserved a G overall because I think my work habits are good and I stay on task most of the time and get my work handed in on time except for the blogs. I hope that my work habits will improve and over time I can reach the goals I have set for myself.

fittness testing

Aerobic: My aerobic fitness work out was climbing the stairs as fast as possible.

Anaerobic: My anaerobic fitness work out would be the long jump.

Glycolysis: My glycolysis fitness work out would be the steps on the benches.

Agility: My agility fitness work out would be the 50m sprint

Flexibility: My flexibility fitness work out would be the back bridge, climbing down a wall. 

Grouse Grind

I did not go on the grouse grind fieldtrip, but in the past I have one the grouse grind and the time it took me to get to the top was 58 minutes and this was last summer and this summer it took me and hour and 8 minutes. I hope next time I go I can beat one time or even both!

my vo2 max

My vo2 max was based on the beep test and it was 39.1 and I hope that next time it will improve. I will be sure to try harder and get a better score.

heart disection lab

Observations on the external part of the heart:
The outter part of the heart was larger than I expected it to be, the color was also not what I had imagined a " heart" being. I always imagine a heart in our body being the shape of a real heart but when we saw the heart obviously it wasn't in the shape of a real heart. the heart was very jelly like and slimy yet firm. The atria and pulmonary trunk were very easy to find. the aorta was a big hole and the pulmonary trunk was a flap at the top as well.

Internal part of the heart:
The internal anatomy of the heart was very interesting to see. it was different then I expected. if you haven't studied the heart you wouldn't know what is really happening in the heart. The chordae tendanae and av valve looked similar inside of the heart, the chordae tendane felt like hard string and the av valve were soft pink and mushy.

Questions:
 1. The most surprising thing about the dissection would be how everything was so much tinier than i imagined to be, and the left side of the heart was so much thicker than right, also the heart has a lot of muscle!
2. The atria and ventricles are different sizes because the atria only has one job to collect and squeeze blood into the ventricles. Then the ventricles are larger because they need to contract the blood.
3. The left ventricle is more muscular than the right ventricle because the left ventricle pumps blood to the entire body and right only does 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 are able to go out of the heart into the blood vessels during contraction. Mitral and tricuspid valves open when the ventricles relax, to let blood to enter the ventricles from the atria.



fitness friday

On this fitness testing Friday I scored a 7.5 on the beep test and was in zone 4. for sit and reach I got a 5, for plank me and my group did it for 1 minute and 25 seconds, for push ups I did 12 of them, and for the balance board I did it for 25 seconds without touching the ground staying balanced. in our next fitness texting I hope to get better times than the last time.

weight room

Lat Pull Down: 3 sets
40 pounds 3 reps
50 pounds 3 reps

leg curl: 2 sets
40 pounds 2 reps

leg press: 4 sets
115 pounds 20 reps x2

Cardio: spin class we did as a little group for 20 minutes

 I don't enjoy going to the weight room at school, I feel there isn't much to do with all the students in a small room, its different then going to a regular gym.

Heart










Coronary arteries:
- It needs oxygen -rich blood to survive
-blood is supplied to the hearty by its own vascular system called the coronary circulation
- aorta branches off into 2 main coronary blood vessels
- these coronary arteries branch off into smaller arteries which supply oxygen-rich blood to the entire heart muscle
- right coronary artery supplies blood mainly to right side of heart, right side is smaller because it pumps blood only to lungs
- left coronary artery branches into left anterior descending artery and the circumflex artery, supplies blood to the left side of the heart
-left side is larger and more muscular because it pumps blood to the rest of the body

welcome to human kinetics coop 12 this is me






I have never  taken a coop class before but I have friends who did take the coop we had last year here at Sullivan, and it looked fun so this year I decided to take the coop. It seemed like an interesting course and lots to do in it. I took the coop to get a different feel of some classes and learn new things other than what we have. my plans for after high school are to go to Sauder and get my license for real estate and mortgage breaking and then go to sfu and take business classes then get a degree in something in the business field. when I am not in school I like to sit around and watch t.v., go for walks, sleep, and go on the computer. over the summer I got really lazy and never wanted to do anything but I did get some exercise in while I sat around sometimes. over the semester I wish to become more active and play more sports. hopefully this course will teach me lots more and be a different experience than what I have already experienced in my regular classes.

Arthropods-grasshopper

Grasshoppers are interesting because they have ears on their bellies, they can fly, and existen long before dinasours. They are herbivors of the suborder caleifera in the orden orthoptera.
