Today We watched videos on the imune system, this animation was one of my favourite vids becuz it was action packed, i also learned alot about the imune System like an antigen stimulates antibodies, also the skin is strong enough to block out most intruders next is the tears but if all else fails the inside attacks, B and T cells work together to get rid of the enemy....
Peace out homes
