What are some diseases? What is disease? : What is disease? Disease is a condition that Function impaired A series of recognizable symptoms Cause known Evaluation for identification Types of disease : Types of disease Non-infectious diseases Genetic or hereditary e.g. hemophilia Congenital e.g. fetal alcohol syndrome Environmental e.g. anemia Not transmitted by a microorganism Not contagious Hemophilia : Hemophilia People are missing the protein that makes their blood clot Bruises become hematomas Cuts can be life threatening Anemia : Anemia Lack of iron in the diet causes reduction in red blood cells Tiredness, shortness of breath, heart failure Checkpoint 2 : Checkpoint 2 What are two types of non-infectious diseases? What causes them? Describe the impact of non infectious disease on our society? Types of disease con’t ….. : Types of disease con’t ….. Infectious diseases Bacterial e.g. cholera Viral e.g. chicken pox Fungal e.g. tinnea Parasitic e.g. malaria Transmitted by a microorganism Contagious Chicken Pox : Chicken Pox Spots that become blisters Blisters contain fluid Blisters become itchy scabs Cholera : Cholera Intestinal infection Diarrhea and severe dehydration Transmitted through contaminated water or food Checkpoint 3: Disease : Checkpoint 3: Disease What is an example of an infectious disease? What are some of the symptoms of this disease? Describe an infectious disease that you have suffered from? Pathogens : Pathogens Not all microorganisms cause disease Yeast: yoghurt Micro flora: healthy skin Pathogens are microorganisms which cause disease How are pathogens transmitted? : How are pathogens transmitted? In the air In water In food In body fluids e.g. saliva By touching By another organism e.g. mosquito These transmitters are called vectors How do pathogens make us sick? : How do pathogens make us sick? Bacteria produce poisons that kill our cells Viruses use our cells to reproduce and then the cell dies Fungi grow and produce toxins Parasites live and grow in our body destroying tissue Checkpoint 4: Pathogens : Checkpoint 4: Pathogens Name a pathogen that you are familiar with. What are its effects? Describe your journey as a pathogen. Virus Reproduction : Virus Reproduction Parasite Activity : Parasite Activity Mosquito Attack Blood cell penetration Parasite Release Body Response : Body Response First line of defense Physical barriers eg skin Second line of defense Cell attack Third line of defense immunity Stop the Spread of Disease! : Stop the Spread of Disease! Preventing Infection Stopping the spread You do not have the permission to view this presentation. In order to view it, please contact the author of the presentation.
