Reminders:
-5 days until final exam
-Today was the last day to hand in all missing assignments
-Last day of Bio20!!

What we did today in class:
1) Mark unit 2 and unit 3 quizzes
2) Overview of unit 4: Human Body Systems

NOTE: Tutorial on Monday 25 from 4-6, the quiz on unit 4 will be due that day as well

Thoughts about material:
-It is a good thing we are reviewing the Human Body Systems because there is a lot of material that needs to be covered.
-If you want to get 80% of higher on the final exam you need to know the basic structure and function of all the body systems plus the "nitty gritty"
-I liked the fact that Mr. Challoner made us do a survey on the class and his teaching. It shows that he is actually willing to improve his class.
- (Digestive system) What is the difference between pepsin and pepsinogen? Pepsinogen is an inactive form of pepsin in a nut shell.

This little website is a compact overview of the systems that we have learned. It gives some of the systems that we didn't learn but it still has good information.
This was taken from the cite:

The human body is made up of a head, neck, torso, two arms and two legs. The average height of an adult human is about 5 to 6 feet tall. The human body is made to stand erect, walk on two feet, use the arms to carry and lift, and has opposable thumbs (able to grasp).



The adult body is made up of:
100 trillion cells
206 bones
600 muscles
22 internal organs

Stuff you should know/ Questions:

1) What do B-cells do in the blod?
answer: They produce anti-bodies with helper T cells

2) Is there a nucleus in the red blood cell?
answer: No.
Why? Because they need the room to transport gasses throughout the body.

3) What type of type of cells are used when trying to diagnose your blood type?
Red blood cells

-The lungs are not symetrical because of where the lungs are. The lungs surround the heart and protect it.
-Hemoglobin combines with carbon dioxide so that the cell cannot connect with oxygen like it usually does. That is carbon monoxide poisoning.

What we did:
- started our review sessions preparing us for finals
- reviewed E and Matter Exchange in the Biosphere
- did practice test pertaining to the above bullet
- started into reviewing Ecosystems and Population Change
Thoughts and Opinions:
- it was good to start review in class considering lots of people probably hadn't started until then
- the first law of dynamics kind of makes me question it, because isn't there the exception of the sun? (unless you get really deep into it and look at the physics part of it all)
- if you took any part of an ecosystem away, the whole thing would have to shift and adapt to maintain a dynamic equilibrium

- Question: What is an agal bloom?

Answer: a rapid increase or accumulation in the population of algae in an aquatic system.

- An example of nitrogen fixing bacteria: Nitrogen fixation is utilized by numerous prokaryotes, including bacteria, actinobacteria, and certain types of anaerobic bacteria. Microorganisms that fix nitrogen are called diazotrophs. Some higher plants, and some animals (termites), have formed associations (symbiosises) with diazotrophs.

Review of the class:
Block 1
-Recall
     -Talked about yesterdays Video Conference
-Mr. Challoner made Bree hold a bag that demonstrated muscle fatigue
-Discussed lactic acid
-Had a motor system power point
-Types of muscles
     -Skeletal
     -Cardiac
     -Smooth
-Focused on Skeletal muscle
-Read Pg.300-301
-Do questions #1 on Pg.304 and #6 on Pg.308
Block 2
Experiment on the Muscular system

Thoughts about the class:
I thought that the video conference was a good idea and I'm happy that Mr. Challoner did it. Thank you! The power point was a good visual of the differences between the three muscle types. The experiment on muscles was not to shabby but it could have been better. Mr. Challoner helped out with the majority of the questions so thanks.

This link is about the smooth muscles in your body. Smooth muscles are like your stomach. Its function is to maintain organ dimensions against force, cells are fastened to one another by adherens junctions.

Review of the Class:

- Recall
     - Quiz
     - Rearange Terms
1. Osmosregulation
2. Disorders
3. Ticket


Thoughts about the class:

I thought that the materail we covered was very intresting. It never knew that 2 small kidneys could be so important to your body. Also osmosrelulation involves all hormones. It is intresting how affective hormones are in your body. They do regulate a lot of reactions and regulations of your body. I wonder if an increase in Na reabsorption can really harm you?

What we did in class:

• Learned about the nephron, the three processes of filtration, reabsorbtion, and secretion. As well as their functions in the nephron.

My thoughts and opinions:

-Learning about the parts of the nephron was kind of hard to figure out, but over all i learned quite a bit from it. It's useful to learn about our body functions so we understand what is actually going on inside. The material is easy once you catch on to it.

Above and beyond:

-The link below is to demonstrate the functions of the nephron in the kidneys:

Stephen Carrier, January 8th (3/3)

What We Did In Class
-We wrote a test on the respiratory system and marked test.
-Started notes on excretory system.

My Thoughts And Opinions
-The test on the respiratory system wasn't extremely difficult. It mainly just covered the basic points of the the respiratory system.

-The notes on the excretory system werent very in depth so far, just learned the three main functions of the excretory system, they are:
-Maintaining blood pH.
-Removing bodily waste
-Maintaing water level in body

Above and Beyond
-This hyperlink is to some information on kidney donation which was a topic that appeared fequently in class.

I thought the class was good. I think we stayed quite focused.
The material was very straight forward. we talked about the respiratory system (hemoglobin, plasma, carbonic acid and how it doesn't turn into a harm for the body) I found it wierd when our body produces an acid that can change our Ph and harm us but thenks to hemoglobin that doesn't happen.

What we learned:

Double Bio

• Exchange xinfo x immune system
• Evaluations
• Complete questions in back of hand out
• Quick Video
• Resp System

My thoughts and opinion:
The class was pretty good, learned more about the resp system.... hard to focus since christmas break was coming up
