It's FRIDAY!

In Class:

- Looked over Michael Dillon's AMAZING scribe post and the Star/Wish.

Went over:
- DOD #7; talked about Lyme disease.

- UP 22-25 and Up 28-31.
- Immune System tree map. (Specific Diseases)

- Took notes about Hummoral Immunity, Antibodies, and Immunological Memory.

D.O.D #7; Lyme Disease

Agent of Disease:
bacteria
Facts:
- Vector of Lyme Disease are ticks.
- Bacteria is from the bite.
-If bit by a tick, it is likely to have a rash forming on the side of the bite.

Notes:

Hummoral Immunity

B-Lymphocytes (B-cells) also known as white body cells: recognize antigens which are present on pathogens.
B-cells produce plasma cells and memory B-cells.
Plasma cells release antibodies.
Memory B-cells remember the antigen so antibodies will be produced rapidly next time.


Antigens: markers on a cell's surface that indicate what the cell is about.

Antibodies:
-antibodies bind to antigens
-antibodies mark antigens for destruction by the macrophages
- very specific
- person's body can produce 10 billion antibodies.


Immunological Memory:


2nd exposure is a lot higher and faster because memory B-cells remembered how the antibodies looked in the 1st exposure.

Cell-mediated Immunity

- T-cells attack body cells that are cancerous or infected with viruses.
- Helper t-cells signal(stimulate) killer t-cells and memory b-cells.
- Killer t-cells (cytotoxic) kill infected cells or foreign tissue.

HINT! :

If you're having trouble with this material or do not understand something, go on MOODLE. There, you will find a couple of videos that Mrs. Stein has posted up in order to help you out and give you a better idea of the material we are learning.

HOMEWORK:

1. Postcard due Monday.
2. UP pg 32 due Monday.
3. UP pg. 37-42 due Monday.
4. Read 35.4 by Tuesday.
5. Homework Pass available before Wednesday.
