Dangers of scuba diving and smoking

During scuba diving, the heart is already at high speed so the vital organs can receive oxygen. But when the divers also smoke, the capillaries aggregate which lead to blockage of blood vessels. If the diver smokes right before the dive, the blood vessels constrict which increases heart rate. This means the heart needs more oxygen which reduces oxygen for tissues and organs. Smokers need to work way harder on their dive than non smokers. Diseases caused are atherosclerosis which is blockage of blood vessels, oxygen deficiency or shortness of blood. The wrong gas exchange can lead to permanent damage to respiratory system.

Ex Science Fitness Goal

My goal is to improve my endurance and balance. For my cardiovascular endurance, I can improve it by using the Nike Running App which times my runs and measures the distance. To improve I can most likely go on runs to improve the amount I run. As for fitness testing, tests like yoyo test, how many hill runs in 30 minutes or just timing how fast I can run 1 mile will help me determine if I've improved. Now for balance, I can work on my balance by also stabilizing my core. Exercises like dynamic balance leg swing, balance step knee-up can help me reach my goal. To test my balance, the board touches or how long you fall in 1 minute for airplanes.
I've used the Nike Training Club App a number of times and I feel like I get the workout I want by using it. It helps me work on specific areas which I want to and if I don't feel like it, I can just use the Nike Running App and run.

Crash Course Video

The two systems connect in a couple ways. First they work together by inhaling and exhaling. The heart pumps blood through the pulmonary artery into the lungs where gas exchange happens and deoxy blood turns into oxy blood. Then returns back to the heart from the pulmonary vein and to the body. A gas exchange happens in the respiratory system and releases CO2 from the body and brings in O2 hence inhaling. I learned that some animals which don't have lungs still take in oxygen through a process of simple diffusion where air goes through pores or wet membranes.

Fitness Testing

Aerobic: running up the stairs 

Anaerobic: 50m sprint

Glycolysis: the steps on the benches for 3 min.

Agility: L Test

Flexibility: splits

 

Balance: balancing on one foot with your opposite arm out

Interim Report

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

So far, the highlights for me have been:
trying different things and learning things about my body I didn’t know before.

I am the most proud of:
my stamina. My goal in the beginning was to improve on my stamina which I have been doing.

The most interesting things I have learned about are:
how our circulation works and the fitness things we learned in superfit.

An example of when I really pushed myself in SuperFit is:
the pond run intervals when I tried to sprint as fast as a could for the one minute.

I could make improvements in:
my balance, and flexibility.

I am really looking forward to:
continuing to work on being fit.

The Basics - WORK HABITS:

Attendance (classes missed and why) - 0

Participation in field trips (woo kim, grouse grind, rock climbing) – the place where I haven’t gone was grouse grind because I missed the bus

Lates (how many & reasons) – just a couple the first week because I didn’t know when the bell rung.

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 always have tried to follow along although I need to engage in participating and talking more

Blog assignment completion - (out of 8 assignments) Comments? Ive completed all of them.

Self evaluation of work habits for each class in coop - G/S/N

Grouse Grind in the summer

lWhen I was doing the grouse grind, I was in my zone 5 but my heart was beating fast and I was breathing heavily. I could feel my face being red and my legs were exhausted. I was really tired to do another step. My sister and I were going at a moderate pace and after the half way mark, hiking up became 100x more difficult. I couldn't go any more because I was exhausted, had no energy and my body wasn't used to doing this type of activity.
I think the body system was aerobic because my heart rate rose and it was an endurance activity.

Weight Room Oct 7

Bike Spin : 20 mins,

20 pound squats : 3 sets/ 10 reps

Lat Pull Down : 50 pounds
                         - 3 sets/ 10 reps

Seated Cable Row : 60 pounds
                              - 3 sets/ 10 reps

Seated Leg Press : 75 pounds
                            - 3 Sets/ 10 reps

My VO2 Max

Based on my previous beep test, my Vo2 is 44.0 ml/kg/min by getting at 9.2 on it and scoring above average. For me that wasn't my best beep test so I know my VO2 max can improve.

Heart Dissection

 

 

Observation on External Anatomy:
  My observations on the heart external anatomy are that the size of the heart smaller than i expected it to be and the shape was obviously not shaped as a heart but round at the top and pointy at the bottom. The color of the heart was pinkish-purple and was much darker and red inside then the outside. Also, the weight was actually pretty light, it weighed around 1 pound and felt mushy in my hands. The atria and pulmonary trunk were on top of the heart and the aorta is the large hole and pulmonary trunk is like an open flap next to the aorta kind of underneath it.

Internal Anatomy:
  My observations on the hearts internal anatomy are that the left wall is 3x larger than the right wall for the atria and ventricle. The chordae tendinae and the AV valves looked similar on both side, however the chordae tendinae felt like hard strings that would not stretch and AV valves were pink, soft and mushy. Some other observations i made were that the internal part of the heart is a darker- red color and much harder.

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 Valve 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.
