Reports, Reports, we're starting our reports
We reported to the class what germ causing disease or "infection" that we've been working on and what we've found out about it. The students are for the most part doing great but we definitely have some gaps.

BACTERIA
SUPPLIES HAVE ARRIVED!
TIME FOR OUR EXPERIMENT! Where do you hypothesize our most bacteria laden part of the school is? See this powerpoint for more info on bacteria.
Or see this interactive bacteria cell.

10 Deadliest Diseases
Someone in class asked me what are the deadliest diseases. Well it depends. Depends on if you mean which could infect people the easiest, which is most likely to kill the host, or which is incurable?
Here is a slide show of the ten deadliest diseases with information bout each.

Definitions and topics
IMMUNE SYSTEM:
A disease that is spread from one organism to another is a contagious disease. Contagious diseases are caused by agents such as viruses, bacteria, protists and fungi. They are spread through water and air, on food, by contact with contaminated objects, and animals like fleas, rats and mosquitoes. Animals that spread disease are called vectors. Some of the most dangerous diseases are spread through sexual contact.
Your immune system is a group of defenses that your body has to fight disease. It is made up of cells, tissues, organs and body systems that fight bacteria, viruses, harmful chemicals and cancer cells.
white blood cell: White blood cells (leukocytes) are the cells of the immune system. Monocytes, macrophages, neutrophils, natural killer cells, T-cells and B-cells are all white blood cells.
Lymph Nodes: an organ consisting of many types of cells, and is a part of the lymphatic system. Lymph nodes are found all through the body, and act as filters or traps for foreign particles. They contain white blood cells that use oxygen to process. Thus they are important in the proper functioning of the immune system.
Tonsils: Organs that trap pathogens in the throat. A mass of lymphatic tissue.
Immune system- the network of cells, molecules, and organs that act together to defend the body against foreign invaders such as bacteria, viruses, and fungi.
Immunity- disease resistance provided by the immune system.
Antibodies- Y-shaped proteins, or immunoglobullins, that are produced by B cells. These proteins attach to antigens and destroy or help to destroy the foreign invaders.
Spleen- Organ near the stomach that produces, stores, and eliminates blood cells. Also holds an emergency store of red blood cells. In case the bone marrow goes out has the ability to make blood cells.
Pathogens- disease-causing agents such as viruses, bacteria, cancers, and toxins.
Vaccine - Weakened or killed microorganisms or toxins administered to induce immunity to infection or disease.
If you were absent and need make up work, write out the answers to these questions:
1.What is it called when a weakened form of a disease is introduced to provide immunity to the body?
2.What is the organ in the throat full of lymphatic tissue?
3.What are pathogens?
4. What is an organ in your left side that eliminates old blood cells?
Then print and do this word find
