What does b-cell do in our immune system?

They make your immune system stronger and protect you against antigens (toxins or foreign substances) the body may have already encountered. How does it happen? Well, B-Cells trigger the B lymphocytes to produce antibodies. These antibodies are a special protein that latches onto the toxins, or antigens. The antibodies stay in your body for life, so that if that toxin ever comes face to face with the immune system again their ready to fight it off and keep you healthy!

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
