Hey thanks!!I am only 9 this year.So this is great for my homework about the human body project.I am in year 5.Thanks!!
this website is REALLY good I have to tell my teacher.
Nice photos but two facts are way off……Can’t freeze red blood cells, thats why there is always a shortage for hospitals. Also if someone loses 1.47lt of blood there is a real danger esp if they only have 3.8Lt
this is pretty useful, but i think i need to know more about cells
