DISEASE (P. 1029) DEFINITION: IS ANY CONDITION THAT ___________ THE BODY FROM WORKING PROPERLY OR MAINTAINING DISRUPTS HOMEOSTASIS

CAUSES OF DISEASE PATHOGENS

FOREIGN PATHOGENS INVADER ORGANISMS MAY CAUSE DISEASE FOUND IN THE FOOD WATER AIR WE EAT !!

EXAMPLES OF PATHOGENS VIRUS BACTERIUM FUNGUS PARASITES

ABNORMAL CELLS MAY CAUSE CANCER. THESE ABNORMAL CELLS WHICH RESULTS FROM UNCONTROLLED CELL DIVISION DUE TO EXPOSURE TO CERTAIN AND GENETIC MUTATION CHEMICALS RADIATION

TOXIC SUBSTANCES lead Or radiation poisoning

POOR NUTRITION SCURVY Goiter Iodine (Deficiency of vitamin C) or ( a Deficiency of Iodine

ORGAN MALFUNCTION HEART ATTACK AND STROKE

INHERITED DISORDER TAY SACHS DOWN SYNDROME KRABBE DISEASE SICKLE CELL ANEMIA

RISKY PERSONAL BEHAVIOR LUNG CANCER AIDS SKIN CANCER SYPHILIS

VIRUS Protein coats ARE COMPOSED OF And DNA. They reproduce when they Invade Living cells

VIRUS EXAMPLE Common cold ( Rhinovirus) Airborne, direct contact with infected person

INFLUENZA 2 TYPES: A,B PLUS SUBTYPES AIRBORNE, DIRECT CONTACT WITH INFECTED PERSON, DROPLET INFECTION

CHICKEN POX AIRBORNE, DIRECT CONTACT WITH INFECTED PERSON.

MEASLES

ARE ( One celled) Organisms BACTERIUM ARE ( One celled) Organisms

Bacterial Illnesses Include ( Poisons from Toxins) given off by some bacteria. (strep throat, syphyilis and food poisoning Antibiotics are used to treat many bacterial diseases

Bacterial disease Examples Tuberculosis

MENINGITIS

TETANUS CONTAMINATED WOUND

PARALYSIS FROM TETANUS

FUNGI ARE ( ORGANISIMS) MADE OF EITHER ONE OR MANY CELLS. THEY INCLUDE ( YEAST) AND (MOLDS). THEY GET THEIR NOURISHMENT BY (ABSORBING) PRE-DIGESTED ORGANIC SUBSTANCES

ATHLETE’S FOOT

RINGWORM

PARASITES ARE EITHER ONE-CELLED OR MULTICELLULAR ANIMALS, THAT SURVIVE BY ( LIVING) AND (FEEDING) OFF OTHER LIVING ORGANISMS

LEACHES

TAPEWORM

MALARIA

SCHISTOSOMIASIS
