Specifically, the thyroid helps regulate your metabolism. Your thyroid is an endocrine gland, which means it secretes hormones. This is what you were thinking of when you tried to place the adrenal glands in the neck.

Gross? Borderline unethical? Crucial to the study of gastric anatomy? Yes, to all of the above. William Beaumont spent years inserting various items into the hole and removing them hours or days later to see how digestion had progressed. Martin, who unfortunately acquired a hole in his abdominal wall when he was shot on June 6th, 1822, and who served the rest of his days as a glorified guinea pig for an Army doctor. We owe a lot of our stomach-related knowledge to a man named Alexis St. This should go without saying, but your stomach helps digest your food using acid and enzymes-though it doesn’t do as much work as you might think.

Your esophagus is just not as long as you think, people. The stomach was surprisingly hard to locate, again, probably because it’s oddly high up. A couple types of liver dialysis are being tested to help those patients. Livers can grow back to some degree if they’re damaged, but chronic damage will eventually cause the liver to fail altogether.

It makes bile to help digest food, secretes hormones, synthesizes proteins, and filters out certain toxins. Glands are organs that produce chemicals (like hormones) in order to release them into the bloodstream. You probably thought this was lower down, didn’t you? Most people couldn’t locate the liver, much less tell you that it’s actually a gland. If two fail, you can try to get a transplant, and in the meantime go on dialysis, which is essentially an external form of filtration that performs basic kidney functions on your behalf. If one kidney fails, you can generally live without it. Filtered blood goes back into the circulatory system, while the urine heads towards the bladder.

A complicated series of membranes selectively allow certain molecules to pass through, which allows the kidneys to remove toxic components and put them into your pee. They sit in the middle of your back, filtering your blood day in and day out. Those lil beans proved fairly difficult to locate. That being said, your biceps aren’t a very functional muscle group, and they’re mostly only worked by doing curls, a.k.a. But listen up non-dudes: if you want those Michelle Obama arms, you gotta pick up something heavier than a three-pound dumbbell. Men are taught more about muscle locations because lifting is a stereotypically male pursuit. Significantly more men than women could identify the biceps, and you’ll never guess why. It’s also why some have to pee more frequently after having children-because shoving a seven-pound infant out of your vagina can really screw with your pelvic muscles. This is why some adults experience incontinence. Muscles in the pelvic floor keep the bladder closed, but these tend to weaken as people age. The bladder is a muscular sac that sits between your kidneys (where your urine is made) and your urethra, which is the tube that your pee comes out of. You should be able to figure this one out, if only based on the discomfort you feel when you try to hold in your pee. And keep in mind that for the actual study, volunteers were given a totally blank body map and asked to show where each part went, which is way harder. Go ahead and write down numbers 1-21 and see if you can match the numbers to the organs. We put together a labeled diagram of all the body parts that the participants were asked to identify. And laugh all you want, but the average person probably couldn’t tell you where the spleen is. Only one in five knew where the spleen went, and just one in four could identify the gallbladder’s home. The only anatomical part that 100 percent of people got right was the brain. How many do you know?

They selected 21 body parts that they reasoned most people would have heard of, based on which organs and muscles are commonly referenced on TV or other popular media. Researchers at the Lancaster University’s medical school tested a group of volunteers to see how solid their anatomy knowledge was. Unfortunately, we’re woefully under-informed.
