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:
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.

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.

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.
heart anatomy
Cornary arteries and veins are the blood vessels that supply blood and carry away away. 
STRUCTURE
|
FUNCTION
|
DEOXY/OXY BLOOD
|
LEFT ATRIUM
|
-collects oxygen-rich blood from the lungs then forces through the mitral valve into the left ventricle
|
OXY
|
LEFT VENTRICLE
|
-largest and strongest chamber, wall is only half an inch thick and it pushes blood through aorta valve into the body
|
OXY
|
RIGHT ATRIUM
|
-collects oxygen-poor blood returning coming back from the body and then it forces it through the tricuspid valve then into the right ventricle.
|
DEOXY
|
RIGHT VENTRICLE
|
- collects oxygen-poor blood from the right atrium and then forces it through the pulmonary valve then into the lungs
|
DEOXY
|
PULMONARY ARTERY
|
-carry blood from the heart to the lungs to pick up oxygen
|
DEOXY
|
AORTA
|
- the largest artery carries oxygen-rich blood from the heart to the rest of the body
|
OXY
|
PULMONARY VEINS
|
-carry oxygen-rich blood from the lungs back to the heart
|
OXY
|
SUPERIOR VENA CAVA
|
-oxygen-poor blood from the upper body returns to the heart through the superior vena cava
|
DEOXY
|
INFERIOR VENA CAVA
|
-oxygen-poor blood from the upper body returns to the heart through the inferior vena cava
|
DEOXY
|
ATRIOVENTRICULAR VALVES (Mitral & Tricuspid)
|
tricuspid controls blood flow from the right atrium to the right ventricle and mitral controls flow from the left atrium to the left ventricle
|
Deoxy/oxy
|
CHORDAE TENDINAE
|
- bring right ventricular walls closer together during contraction. -pull the AV Valves open during atriole systole
|
Left oxy
Right deoxy |
SEMI LUNAR VALVES (Pulmonary & Aortic)
|
-pulmonary valve control blood flow from right ventricle to the pulmonary arteries and aortic valve controls blood from left ventricle to aorta
|
deoxy/oxy
|
SEPTUM: separates left from right- /

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.
