What is the role of Insulin in the body?
Insulin is a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food you wat for energy or to store glucose for future use. It helps keep your blood sugar level from getting too high or too low.
Explain how infections are spread through people and animals.
People: Through spit, saliva, or sexually transmitted Animals: Through saliva, bites, or scratches
Explain how the body uses each of the following to defend against infectious disease: 1. Physical Barriers 2. Chemical Barriers
Physical barriers help prevent pathogens from exerting the body. Chemical barriers destroy bacteria and cause body changes that help cells inside the body fight infection.

Cancer is the overgrowth of cells. Cancer occurs when cells begin to grow and multiply in an uncontrolled way.
What are the beauty influences and how do they affect skin cancer rates around the world?
-Beauty norm in USA and other countries is tan skin --> more people are influenced to tan indoors or out which causes higher skin cancer rates (1 in 5 people in the US develop skin cancer -Beauty norm in Asia is pale skin --> less cases of skin cancer

Wat are long-term affects of each type of diabetes?
-Eye Problems -Kidney Disease -Nerve Damage -Gum Disease -Foot Problems
How does geography put people at risk for melanoma?
-Higher Altitude (as altitude increases, so does the intensity of the sun's rays; less air molecules, easier for rays to reach people) -Sunbelt States -Hole in Ozone Layer
List 3 reasons why tanning beds are so harmful to our health.
-Increased chances of skin cancer -Linked to Skin Cancer -Can impair immune system
How do you treat each type of Diabetes?
-Insulin injections -Insulin pump -Insulin shots
What are the reasons for the rise of Melanoma in the PNW?
-People think that they don't need to wear sunscreen on cloudy days -More outside activities --> high elevation -Reflective surfaces
What are the Warning Signs and Symptoms?
-Urinating frequently -Abnormally thirsty -Weight Loss -Often feeling tired
What is the difference between a communicable disease and a non-communicable disease?
A communicable disease is an illness caused by a pathogen that can spread from living being to another. A non-communicable disease is an illness that is caused by something other than a pathogen.
What is the definition of Chronic Disease?
A non-communicable disease that persists for a long time or is reoccurring in nature.
What is the definition of Type 2 Diabetes?
A person with Type 2 Diabetes still produces insulin, but the body doesn't know respond to it normally. Glucose is less able to enter the cells and do its job of supplying energy. This causes for blood sugar levels to rise, thus creating more insulin.
What is the definition of Remission?
After treatment, a doctor will test to find signs of cancer, if none are there, that is called Remission.
What is the definition of Prognosis?
An estimate at how well a person's treatment is working and how likely it is that this cancer will come back.
What is the definition of Communicable Disease?
An illness caused by a pathogen that can spread from living being to another.
What is the definition of Non-Communicable Disease?
An illness that is caused by something other than a pathogen.
What is the definition of Virus?
An infective agent that typically consists of a nucleic acid molecule in a protein coat
What are the layers of Skin?
Dermis: Deepest layer of the sun Epidermis: Outer layer that sheds every 15-30 days
What is the definition of Insulin?
Insulin is a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food you wat for energy or to store glucose for future use. It helps keep your blood sugar level from getting too high or too low.

Tumors are lumps that can interfere that can interfere with the body's normal process and are caused because cancer cells continue to grow and dive and gather.
What are the differences between both types of Diabetes?
Type 1 Diabetes results when the pancreas loses its ability to make the hormone insulin. The person's own immune system attacks and destroys the cells in the pancreas that produces the insulin. Once destroyed, they can't produce more insulin again and a person with Type 2 Diabetes still produces insulin, but the body doesn't know respond to it normally. Glucose is less able to enter the cells and do its job of supplying energy. This causes for blood sugar levels to rise, thus creating more insulin.
