I have two questions for living environment.?

[Lex J]

I actually have two living environment regent questions in which they are very similar.
1.)Name an organ in the human body where molecules diffuse into the blood( cant it be placenta?)
2.) Describe one example of diffusion in the human body. in the description be sure to identify the place where the diffusion takes place. Identify the substance that diffuses there and identify where that substance diffuses from where it diffuses to, at that place.( Can't the answer be placenta, carbon dioxide , and diffusion of carbon dioxide of the placenta to the fetus?)

Placenta is a great answer. So is lungs (gasses diffusing in and out) or the large intestine (water moving from inside to the body). When answering be clear on which direction each substance is going. For example, in the placenta, carbon dioxide is leaving the fetus's bloodstream and entering the mother's bloodstream while oxygen is going from mom to fetus. Good luck!
