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.
