Run


The lung







questions: 

2. Real live lungs are different than the model because  one there is no bronchi , bronchiolis or avoli in the demonstration. 2 . the size of the thoracic cavity and the lung is disproportionate. As well two lungs are contained in the thoracic cavity. 3. there is no intercontinental mussels shown.

3. The general mechanism of the lungs is displayed in this model as it expresses the fact that air does not get blown into our lungs , but it is the diaphragms movements. When the diaphragm is contracting air is being blown out of our lungs due to less space when the diaphragm is expanding air goes into the lungs due to more space.

Exercise science


Fitness Testing Results
My best out of the types

A) aerobic :  Did not turn out too well the bench steps where meant  to be aerobic ; however , when it was done it could not be sustained for long periods of time. To make it an aerobic activity It would have need to slow down. 

B) anaerobic: The hill run would be my best

C) ATP CP system: The sprint race. sprint as fast as you can lasted less than 10 seconds

D) flexibility: the back bridge was my best. I was able to go all the way down and touch the ground.

E)  power: would be the long jump I got  175 cm 

F) agility : Box test. you had to nimbly move fast around a coned area. 

What I want to improve on my core and legs. Specific I'm testing myself with wall sits , plank as well as faster speed on the hill sprints.  will test my wall sits an my plank by time, and for my hill sprints on how many I can get in a time. Some apps that can help are the Nike training app. I'd be able to isolate the groups legs and core by choosing specific exercises which would help me.

Grouse Grind



     The grouse grind was physiologically challenging  just as physically. My musses felt extremely fatigued , chock full of lactic acid and quite literally I thought i'd never never reach the top. some moments I was using my arms to push me up , rather than a crawl. The burn was pretty intense however when I made it I was relived and ecstatic when I reached the top at the cafe and saw everyone there. the teachers smiling. What really affected me was my breaks I should have kept a constant pace. Once I stopped that's when the lactic acid took its most affected as it demotivated myself to keep going.  

   Some factors I kept note of was my heart rate. I found that Taking smaller steps had less strain and larger steps had more and took more oxygen. My body  temperature felt really hot. I was sweaty and red like a tomato. my veins where coming closer to the surface because it was cooler.

Out of the 3 energy systems two where being used areobic and anaerobic gylocides. This is because the activity was enduring sustaining it for a long period of time as well as gylocieds because we had to use large parts of our mussules which needed to take time to recover

Vo2 Max

My Vo2 max is in the above average  at about  44 for a 18 year old woman. The hill run that the class did on the 6th was Anaerobic glycolysis as it produced lactic acid and we were doing inter-volt sprints around the 30 -60 sec range to get up a rest to regain our self and continue. Wile running we where using glucose or glycogen in mussel & liver as fuel.

Heart Dssection


Heart Dissection

You will be exploring the heart, making observations, taking pictures and labelling them during this dissection.  And posting all of this to your blog!

External anatomy: 


Internal Anatomy:
please note that sideways pictures where not intentional. Skitch  unfortunately flipped them. 



Observations:  The outer parts of the heart were very muscular and thick. The septum was distinguishable as its coloration was white going across the deep red heart. It size was a little larger than my hand and was very cold , due to it being previously frozen. Once it thawed out and was rinsed with warm water , the insides of the valves felt stretchy yet strong. To be expected ,it was hollow inside with enough room to wiggle my finger around. In one of the valves there were a considerable sized blood clot. 

 Cutting the heart with scissors  was difficult because It  was very muscular ,the left ventricle being a lot thicker. Inside the heart was different shades of red , with the exemption of the Cordae Tendenae. Which was white and very stretchy. Also to be noted the wall of heart were deep purple.  the texture inside was slippery with ______ lining around it.  The semi lunar valves where present and were little stretchy flaps that when stretched looked like pockets.

Questions: 

1. I've  already cut a heart before ; however , I forgot what it looked like inside as well as I now new more information that it was more interesting to me.  I re- surprised myself. The most shocking part was how stretchy both the Chordae Tendinae and the Semilunar Valvles where.

2. The Atria and the ventricles are different as  ventricles are required to be larger. The artuims purpose is to collect the blood and direct it to the ventricle which is where the blood is being physically pumped. Making it more muscular.

3. The left ventricle was more muscular than the right because right ventricle only needs to carry de-oxygenated blood to the lungs and back , rather having to push  oxygenated blood throughout the whole body. head , feet , everything. 

4. The heart valves are very stretchy flaps as well as the Chordae Tendinae which are thick but strong. their purpose to keep the blood flowing where its suppose to be flowing. The heart could not work if blood was aimlessly flowing. it would never get to where it needed to be. 

5.


For the left side of the heart , (which deals with oxygenated blood) It is first transported through the pulmonary veins which then collects in the left atrium again being conducted to the left ventricle passing a semi lunar valve which is then pumped out of the aorta to be distributed to the body.
