What is a pathogen
|
Something that can cause disease, bacteria, virus fungi
|
|
|
How do we stay healthy most of the time
|
Immune system, innate immunity
|
|
|
What is stress
|
Anything that pushes our body out of homeostasis
|
|
|
How do we deal with stress
|
GAS
General Adaptive Syndrome |
|
|
What are the stages of GAS
|
Alarm, Resistance, Exhaustion
|
|
|
What happens in the Alarm stage of GAS
|
Immune system jumps into action, releases epinephrine, blood sugar, blood pressure and heart rate goes up. Blood pumps faster to get more O2 to muscles, blood leave stomach
|
|
|
What happens during the Resistance stage of GAS
|
Use extra lipids, goal is to survive stress
|
|
|
What happens in the Exhaustion phase of GAS
|
no more lipids, organ failure, cannot maintain homeostasis, death
|
|
|
What composes the Innate Immune System
|
Skin, Mucous membranes, phagocytes, inflammation, complement,, interferon
|
|
|
What fills spaces between dermis cells
|
Keratin
|
|
|
What causes a tanned appearance

|
|
|
What makes melatonin
|
Melanocytes
|
|
|
What makes Keratin
|
Kerainocytes
|
|
|
What do complement proteins do
|
When they detects a protein they combine like the power ranges and poke a whole int he cell
|
|
|
What causes a tanned appearance
|
Melatonin
|
|
|
What does interferon do
|
Send a warning signal to neighboring cells that htere is a pathogen attacking
|
|
|
What makes melatonin
|
Melanocytes
|
|
|
What do pyrogens do
|
Whn working raises body temp causes fever
|
|
|
What makes Keratin
|
Kerainocytes
|
|
|
Why does fever help fight pathogens
|
Fever raises metabolism, all cells work harder to fight infection
|
|
|
What do complement proteins do
|
When they detects a protein they combine like the power ranges and poke a whole int he cell
|
|
|
What is inflammation
|
Tiny fever in specific place. Spped repair, slows pathogen
|
|
|
What does interferon do
|
Send a warning signal to neighboring cells that htere is a pathogen attacking
|
|
|
What do phagocytes do
|
Phago = eating
They eat pathogens and destroy them |
|
|
