• IMMUNE SYSTEM

• 1)SKIN: made up of dead cell containing a protein : keratin 2)NOSTRILS : contain hairs that traps dust3)BLOOD CLOT4)HCL IN STOMACH

• MACROPHAGES

• they swallow the intruder whole and trap it inside a membrane ..then the enemy is broken down by enzymes  and is killed

• they cause inflammation by ordering the blood vessels to  release water into the battlefield so fighting becomes easier

• they release proteins called neutrophiles. they blood and move to the battle field and fight furiously they generate barriers and kill the bacteria . they r so that they can kill healthy cells..so that they commit suicide after 5 days to prevent themselves causing much damage  

• they are especially good at numbing up the bacteria which antibodies have attached to

• the dendritic cell gets active and starts to collect samples from the enemies and rip them into pieces and present the parts on their outer layer

• it is looking for a helper T-cell that combines the parts of the intruders which the dendritic cell has presented on its membrane 

• when it finds one,the helper T-cell is activated and quickly duplicates its self thousands of times 

• some become memory cells which will stay in blood to make you immune to this kind of disease

• Some travel to the field of the battle to help out 

• FIRST LINE OF DEFENSE 

• helper T-cells stimulate them and tell them "work harder we still need you , don't die" this also ensures that the factory dies if the infection is over so the body don't hurt itself
