Fetal pig dissection

We did the fetal pig dissection and it was really interesting to see the heart and the intestines. The fetal pig showed how everything Is all connected from all the. This was a very valuable expiriance and learned a lot from it.

how much urine can a bladder hold?

A normal adult bladder can hold anywhere from 16 to 24 ounces about 500 to 750 mL before the urge to urinate becomes overwhelming. Everyone's bladder is different though, so some can hold more than that amount, some less.

PLAYLAND!!!

• Heart Rate: how does waiting in line for a ride affect your heart rate?  Did you record your heart rate before and after (any evidence)? How about riding on the ride - what affect did it have on your heart rate? 

-When in line the ride didn't really affect my heart rate until i was really close to getting on.once i was on the ride my heart rate did go up a little because i am afraid of heights.

• Why do you think your heart rate is affected?

-Most of the time my heart rate was affected because one i was really excited to go on the ride and second because i am really afraid of heights. 

• Breathing Rate:  Was your breathing rate affected by the rides?  Which ones?

-My breathing rates were always the same they never really changed.

• What other physiological effects (on your body) did you experience?  Can you explain any of them?

-I would get really giggly before i would go on a ride, i would also talk a lot and cant stay still.

Blood flow

This is our video of the blood flow through the heart. http://m.youtube.com/#/watch?v=QTDf8PKyalU&feature=youtube_gdata_player&desktop_uri=%2Fwatch%3Fv%3DQTDf8PKyalU%26feature%3Dyoutube_gdata_player

I may be short but but i have big lungs!

so we did a vital capacity test in class and it tuned out that i got the second highest in class wich was a 4.1! yeah i can hold lots of air.

1. How does your vital capacity compare to others in the class? Describe some reasons why you think your vital capacity is what it is. Why are the highest and lowest vital capacities the way they are?

-your vital capacity compared to others in class can all vary depending on how we all  exercise our lungs some people are more athletic or some people play intruments.my vital capacity is the way it is because i may be short but i have a big frame compared to other girls in class. the lowest vital and the highest capacity are the way they are because some people have bigger or smaller body frames and it depends on how they exercise thiere lungs.

2. How much air is in a usual breath? Why are our breaths the volume that they are?

-There is 500ml of air in our usal breath we only breath that much in order to conserve our energy.

3. How is the mechanism of exhaling forcefully different than a usual exhalation? Why would practice at this via exercise/instrument playing/singing make you better at it?

-Breathing for us is automatic no need to think about it we just do. just like any other muscle in our body if we work it the stronger they will get that is why when people who  exercise or play insruments have stronger lungs they are consitanly working them out.

i made a lung!!! yeah just one.

So, we learned how we breath the contraction of the diaphragm is what occures when we inhale, and it relaxes when we exhale. When we breathe, the ribcage expands to allow the lungs enough room to inflate. When the diaphragm contracts the air rushes through the trachea and  into the lungs. They deflate when the diaphragm goes back into it's resting position that part requires a muscle contraction of the diaphragm.
