Hi and today I am going to teach you about the circulatory system. White blood cells fight off infections and cancer. plasma takes nutrients and hormones to the body.
What I did was I mostly practiced white blood cells, red blood cells, plasma, and platelets. I loved it so much. I learned that red blood cells fead oxygen to tissues and organs, platelets clothes blood and so much more.
I think science is going amazing so far because you can not just learn about want the teacher wants you to learn but you can also learn what you want to learn.
