What does engagment look like?

Engagment in biology to me means always being in class on time and prepared. It means listening to the discussions , following along with notes and making sure that if i dont understand something i take the time to find the answer or figure it out.

How much blood does the heart hold?

The left and right atriums each hold 3.5 teaspoons of blood, whereas the ventricles both hold a little more then a quarter cup . Although both left and right atriums and ventricles hold the same amount of  blood the left sides walls are 3 times thicker then the rights.

How big are my lungs?

Ever since I learned that my lungs can hold 4.5 liters of air , I've been wondering how big they actually are. Lungs are normally the size of a rugby ball when fully in tacked, but if you were to take all the alveoli that makes up your lungs and laid them out side by side it would cover a tennis court.

wah?

 

The alveoli have a lot of surface area. That is incredible. The human body amazes me everyday.

All my info I got from here...

So I have large lungs....

So yesterday we tested our vital capacities... and it was proven that i have very large lungs for a girl my age. My vital capacity hit 4.5 litres or 4500cc.This is way above average for a girl my age because the average is 2. It is even higher then the male average of 4. My vital capacity was the highest of the girls in my class. I believe that my vital capacity was so high because I am tall and I play the alto and tenor saxophones. I think that a lot of people have lower capacities because they might be a bit shorter or not exercise their lungs as much as I do. The typical amount of air exhaled is only half a litre. Our average breaths do not use our full vital capacity because it would take too much energy to take deep breaths constantly. To exhale forcefully is different from the normal exhale because when normally exhaling it is used to rid the body of carbon dioxide and oxygenize the brain. Meanwhile forcefully exhaling is only a test of the lungs capacity and is not required for the normal breath. Playing an instrument has helped my lungs to have a higher lung capacity because I take large breaths while playing therefore increasing my lung capacity. General exercise would allow for a larger lung capacity because you are using your lungs to their full capacity . Its just like exercising any other muscle in your body, the more you use it the stronger it gets!

Interm report

Biology 12 with mrs. Phillips has already been amazing ! I cant wait to see what adventures will come . Making the digestive system t-shirts has been my favorite thing so far and its also the thing i feel i was most successful at.( perhaps because it was so creative and crafty.) my work habits need to improve a little because i still havent finished my lab.. But besides that i feel my work habits are very good . Everyday i work with my classmates and i feel that it has been beneficial to my learning because whenever i dont understand anything they are always there to help. My goals in bio twelve are to continue my knowledge of biology, specifically the human body. Another goal is to get a high B or and A .
Biology is my favorite class and i cant wait to see what other fun things happen in this course.
