hearty. :)

lalala.

well. let's start off. :D presenting, the cardiovascular system. :) primarily, there are 3 components of the system: blood vessels, heart, and blood. first stop is the blood vessels. blood vessels may be arteries (brings blood away from the heart), veins (brings blood to the heart) or capillaries (where exchange of gases, nutrients, etc. happens with the blood). heart has different chambers that helps in pumping the blood throughout the body and a simple organ that has two pumps working together. and blood, may have red blood cells (erythrocytes), white blood cells (leukocytes), and blood platelets (thrombocytes).

lululu.

i would explain this as pump with lubdupp sounds. :) and how they were pumped. :)

lalula.

if i were the teacher, i would play a video clip about the heart and carefully explain to them what or how they works. :)
