DISEASE AND YOUR BODY STUDY SHEET
Objectives:
· Be able to describe the difference between infectious and noninfectious diseases.
· Be able to tell how the body fights diseases.
Terms to Know:
· Disease
· Pathogen
· Infectious disease
· Noninfectious disease
· Communicable disease
· Chronic disease
· Immune system
Any harmful change in your body or mind is known as a disease. Many things can cause a disease to occur in the human body. Some of these come from microorganisms and viruses that are too small to be seen with the human eye. Some microorganisms include bacteria, fungi, and protozoa. Most microorganisms are harmless but some are pathogens. A pathogen is anything that causes a disease. An example of a pathogen would be the flu (influenza) or strep throat.
Some diseases are not caused by pathogens. They are inherited. An example of an inherited disease would be muscular dystrophy. In some diseases the body attacks its own tissue, like arthritis. The environment, like asthma triggers some diseases. Other diseases have more than one cause. Finally, some diseases, such as Alzheimer’s, the cause for the disease is unknown.
An infectious disease is any disease that is caused by pathogens that invade the body. Some infectious diseases can be passed from one person to another person. This means that the disease is communicable or able to be passed from one person to another.
A non-infectious disease, such as cancer, heart disease and diabetes, is a disease not caused by a pathogen. They are diseases that are non-communicable. Injuries from accidents can also cause diseases. A disease that lasts a long time is called a chronic disease.
The immune system is made up of tissues, organs and cells that fight pathogens. White blood cells and several organs (like the spleen), protect you against pathogens. You should take care of your immune system by eating right, getting plenty of rest and exercise, and reducing stress.
YOUR DEFENSES AGAINST DISEASE:
· Skin
· Mucous Membranes
· Sweat, Saliva, and Tears
· Stomach Acid
· Helpful Microorganisms, that take up space of harmful microorganisms
Some Infectious Diseases: Some Noninfectious Diseases
1. Common Cold 1. Sickle Cell Disease
2. Influenza 2. Cystic Fibrosis
3. Chicken Pox 3. Muscular Dystrophy
4. Strep Throat 4. Type 2 Diabetes
5. Hepatitis 5. Allergies
6. Tuberculosis 6. Cerebral Palsy
