What is the role of the immune system?
THe role of the immune system is to deal with any infectious microorganisms that enters the body.
1 of 21
What does immune response do in our body?
white blood cells picks up anything that enters the body. Things like microorganisms is foreign to our body then it's engulf the microbes and digest them.
2 of 21
Is white blood cell is specific or non specific?
White blood cells are non specific - they attack anything that's not meant to be there.
3 of 21
What is memory cells?
Some whtie blood cells stay around in the blood after the original infection has been fought off.
4 of 21
What does the memory cells do when the anigens enters the body for a second time?
They quickly reproduce a lots of antibodies to kill the antigens before you get ill.

What is immunisation?
Immunisation involves injecting dead or inactive microorganisms.
6 of 21
What is the effect of having a vaccine and drugs?
vaccines and drugs can never be completely safe for everyone. People can have side effects when using them which creates serious of illness.
7 of 21
What are antimicrobial?
Antimicrobials are chemicals that inhibit the growth of microorganisms or kill them, without seriously damaging your body.
8 of 21
Can antimicrobial clears virus?
No, antimicrobials can't kill viruses.

What is blind trials?
Blind trial is used to test patient with drug or a placebo. Patient doesn't know if they given the drugs or anything.
10 of 21
What is open label trials?
Open label trials are used when you can't mask the treatments being tested, e.g. if one is a drug and another is exercise.

What is blood vessels?
Blood is circulated around the body in tubes called the blood vessels.
12 of 21
What is the job of heart?
The heart is a pumping organ that keeps the blood flowing through the vessels.
13 of 21
What does right and left side pumps does?
The right side pumps deoxygenated blood to the lungs to collect oxygen and remove carbon dioxide. THe left side pumps the oxygenated blood around the body.
14 of 21
How does blood supplied to the heart?
The blood supplied to the heart by two coronary arteries, which branch from the base of the aorta.
15 of 21
What are the three major types of blood vessel?
Veins, Arteries and capillaries.
16 of 21
What does Arteries do?
Arteries carry blood away from the heart to the body cells (including the heart muscle). It comes out of the high blood pressure, so the artery walls have to be strong and elastic. They're much thicker.
17 of 21
What does Veins do?
Veins carry blood back to the heart. The blood is at lower pressure in the veins so the walls don't need to be as thick. They have a bigger lumen then arteries, to help the blood flow more easily. The valves to keep blood flow in the right direction.
18 of 21
What does capillaries do?
Capillaries are branches of arteries that are really tiny. They carry blood really close to every cell in the body to exchange substance with them. They have permeable walls to diffuse in and out. They supply nutrients and oxygen, and take away waste

What is homeostasis?
Homeostasis is all about balancing inputs with outputs to maintain a constant internal environment.
20 of 21
What does automatic control system does?
Automatic control system regulate your internal environment - these include both nervous and hormonal communication systems.
