I’m not going to write seven paragraph, but I’ll do some common differences you can quickly build off of (also use very large words and long sentences to fill the paragraphs, doesn’t even have to be detailed) Brain controls nervous system. Brain controls out movement. The brain gets the direct messages for our movement responses. The heart pumps blood throughout the body. The heart had arteries, and veins. Veins are blood carried in, arteries are blood carried out. Hope this can help :)
The ventricles of the heart have thicker muscular walls than the atria. This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria.
