Term
| Life cycle of a protozoan |
|
Definition
| during the trophozoite stage the protozoan is actively feeding. As nutrients begin to dry up the cell loses motility and comes more round. The early cyst wall forms. Then the protozoan is a mature cyst, it now is dormant and can survive harsh conditions. As the environment becomes moist and nutrients are restored the cyst wall breaks open. Now the trophozoite is mature again |

2. Flagella
3. Cilia |
|
|
Term
|
Definition
| Amoeboid Movement... crawing motion accomplished by protrusion of cytoplasm of the cell |

Term
| Transmission of Chagas Disease |
|
Definition
| the REDVIID BUG feed on the bug of a host such as a dog or cat. Inside the redviids intestinal tract the TRYPANSOME is multiplied. The bug will then bite a mucous membrane (usually lips). After the bug bites it will defecate in the wound, contaminating it. the bug then goes on to a different host, continuing the cycle. The human scratching the bite mark contributes to the disease. The trypanosomes become established in WBCs and muscle of the human and will begin to mulitply |

| Transmission of Pinworms! |
|
Definition
| the person touches something or someone who is infected and then swallows the egges. The eggs hatch and the male and females reproduce. the new eggs are laid in the anus causing itching. When the person scratches the fingers, sheets and other objects are now contaminated. the cycle restarts |
