It's a Friday!!!

Agenda:
1. Take u UP 28-31 with stamp sheet
2. Star/Wish/Attendance
3. DOD #7
4. Go over UP 22-25
5. Discuss Immune System, go over UP 28-31
6. Begin homework if time

The first thing that we did was to go over the disese of the day which was Lyme Disease. The agent of disease is Bacteria. The interesting anf Important Facts are that bullseye rash appear, vector born disease (tick), treated with antibiotices, and prevented by proper clothing, and that death is rare.

The second thing we did was to go over UP 22-25. The answers are as follows...
Pg. 24
5. D
6. A,D, C
7. Antibiotic A: Monday evening
Antibiotic B: Never
Antibiotic C Thursday evening
Antibiotic D: Monday afternoon

We then took some notes. At first we used the chart that we made on Thursday, but then we went off of that and took some other notes. you can look at the last scribe (Hannah's) if want to look at the chart. The only thing that we added was that under B-cells we added antigens/antibodies. Here is the other notes that we took:
Humoral Immunity:
B- lymphocytes (B-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 nest time

Antibodies:
Antibodies bind to antigens
Antibodies mark antigens for destruction by the macrophages
Very specific
Proteins found on the surface of the cell

Cell Mediated Immunity:
T-cells attack body cells that are cancerous or infected with viruses
Killer T-cells (cytotoxic, T subscript c) kill infected cells or foreign tissue
Help T-cells (T subscript h) signal (stimulate) killer T-cells and memory B-cells


The last thing that we did in class was the go over UP 28-31. Following are the answers to the pages.
Pg. 28:
Cell: B-cell
Function: Matures in the bone marrow and releases antibodies
Cell: Suppressor T cells
Function: Slows down or stops the activities of B-cells and other T-cells once the danger of the infection has passed
Cell: Antibody
Function: Protein that attacks antigens
-Paralyze
-Clump
-Mark for destruction
Cell: Helper T-cells
Function: Identifies foreign cells in the body. Stimulates the other cells to fight infection
Cell: T-cell
Function: Matures in the Thymous and fights infected body cells
Cell: Killer T-cells
Function: Transfers special proteins into the cell membrane of a pathogen that cause a cell to rupture and die. Involved in the rejection of transplanted tissues.
1. How does the shape of an antibody affect its functioning?
It is very specific
2. What is agglutination and what role do antibody molecules play in the process?
Agglutination is the clumping of bacteria, red blood cells, or other cells, due to the introduction of an antibody

Pg. 29:
3. What is a secondary response and which cells are involved in such a response?
If a pathogen pasts the skin, the 2nd lone steps in. Memory cells.
4.Which cells from the chart is involved in cell-mediated immunity?
T-cells
5. HIV, the virus that cause AIDS, attaches to receptors on the surfaces of a type of cells that appears in the chart. Which cell is involved in this process?
Helper T-cells

We did not have time to do our homework in class.

Homework:
Postcard- Monday
UP 32- Monday
UP 37-42- Monday
Read 35.4 by Tuesday
Test Tuesday (Look at labs, read chapters, notes, objectives in packet)

The next scribe will be Daniel A.
