1. Organism that carries a disease2. Use of chemicals to destroy cancer cells3. Occurs when your body makes its own antibodies4. Overly strong reaction of the immune system to a foreign substance.

Active Immunity

Biological vector

Allergy

Chemotherapy

5. Complex group of defenses the body has to fight disease.6. Killing most bacteria by heating food at high temperatures.7. Occurs when antibodies are introduced into the body.

Immune System

Passive Immunity

Pasteurization

Allergies _____________. between the death rate and the degree of cleanliness in surgery in the 1800s.l

Dust is an allergen for some

Reactions include watery eyes

Most reactions are not serious



What is true about immunities l.jpg
What is true about immunities? of time

Newborns have passive immunity

Immunities build as you grow older

Vaccines create active immunities


Slide13 l.jpg
A _________ is a substance made by an organism in response to invading substances and disease-causing organisms.

  • Antibody


What is true about hiv l.jpg
What is true about HIV? to invading substances and disease-causing organisms.

Victims of it often die of pneumonia

It can be transmitted by contact with bodily fluids

It breaks down the immune system


What is true about cancer l.jpg
What is true about cancer? to invading substances and disease-causing organisms.

It results from uncontrolled cell growth

Cancer cells do not function normally

Its cells travel in the body

Bacteria

Viruses


What is the relationship between pasteurization and disease l.jpg
What is the relationship between pasteurization and disease? _________.

  • The pasteurizing process heats food to temperatures that kill most harmful bacteria. By killing harmful bacteria, the chance of disease is decreased.


Explain how hiv affects the immune system l.jpg
Explain how HIV affects the immune system. _________.

HIV attacks cells in the immune system called lymphocytes. Theses are the cells that normally fight antigens that cause disease. The body is left with no way to fight invading antigens, and the whole immune system breaks down. AIDS patients develop other diseases such as pneumonia, cancer, or tuberculosis and usually die from theses diseases.


Syphilis l.jpg
Syphilis _________.

  • Cause: Bacteria

  • Means of transmission: Sexual Contact

  • Stage 1 Symptoms: Mouth sores

  • Stage 2 symptoms: Rash, fever, lymph glands swell

  • Stage 3 symptoms: Infect cardiovascular and nervous systems.

  • Treatment: Antibiotics in early stages most effective

  • Outcome if untreated: Damage to body organs, death


Slide22 l.jpg

Immune system _________.

  • Your ________ is made up of cells, tissues, organs, and body system that fight foreign organisms. ___________ is a barrier that prevents many pathogens from entering the body.

  • Your circulatory system contains ___________ blood cells that surround and digest foreign organisms and chemicals as they enter the body. Sometimes, when the blood cells cannot destroy the bacteria fast enough, a ______________ develops.

Skin

White

fever


Slide23 l.jpg

cilia _________.

cough

  • Your respiratory system has ___________ and mucus in the nose and throat to trap pathogens. When you __________ you expel pathogens.

  • In the digestive system, ___________in your mouth, stomach, pancreas, and ____________ destroy pathogens. ______________in your stomach kills bacteria that enter your body on the food that you eat. If you do get sick, your body has defenses in the form of _____________.
