Apparently we don't have kidneys.Bought this for my 4 year old grandaughter's doctor office in her playroom. She knew we had skeletons insde us but don't think she realized there was so much more. Poster is very graphic but she returns to it again and again asking me to tell her about the organs and body systems.As an RN, I know this poster would be great for nursing students as well as anyone taking a biology course.Poster is quite large but made of heavy paper. It was shipped quickly and securely. I would definitely buy from this seller again.Perfect to have by my desk as a video remote medical interpreter. Wish it had more detailed info.Used to help with a speechThis poster has a pretty good overview of the human body and its systems, but unfortunately it isn't very detailed. I guess this is understandable given the amount of information that they're trying to fit into the space, but I was still a bit disappointed.That being said, it's a fun, colorful, and educational addition to my poster collection!I really like this poster. It has good basic information for those who need to refresh their memory or those who want a reference for some of the basic bones and muscles in the body. I will say that the material of the poster is pretty weak and flimsy, but the problem can be easily resolved if you take it to a store like Office Depot and have it laminated. It's a great poster :)Purchased for homeschooling anatomy study unit. Have it hanging up over our anatomy table that includes a skeleton, 3D human body model and the toobs organ set. Also purchased several organ books. It brings the whole area together. My daughter loves matching stuff up to the poster. Creates great visual presence.First of all, for this price, it's hard to make too many complaints. I just wanted to note for anyone who may not realize this that the poster is fairly simple... as I suppose you could expect when you try to fit all the body systems in one poster. Most of the information on here I learned when I was in middle school, although a lot of us could probably use a brush up on some of this stuff! The poster is probably best, however, for kids/older kids under the age of 14.Get it, i use it for college, and tells me the majority of the systemsCoolGood!clarity
