I’m taking an Anatomy and Physiology class and we just hit the section about the Digestive system. My book is doing a very bad job of explaining half of it. I feel rather silly asking this question, but what is exactly is the difference? Is the large intestine also the colon? Is it a part of the large intestine?

Thank you for taking the time to look at this question and for your answers. =]

I am now 20 and have had pain right below my left rib cage for over a year and a half now. It’s a very sharp pain. Just recently it has felt like a bruise, when nothing visible was there. sometimes it will feel like there is a cut right below my rib, and still nothing visible. These pains will come and go, sometimes lasting days sometimes minutes. I thought of the pain as a broken rib on my left side protruding through my external oblique. I went to the doctor and had an x-ray and they found nothing at all. I can feel an abnormal bump..all most like the last false rib was turned sideways, but again the doc could not feel what i can. Just recently my fiance felt it, assuring me that I wasn’t over reacting. I feel that I have some sort of digestive problem. Although I’m not sure if it relates. I think (DON’T ACTUALLY KNOW) that there is a problem with my parastalsis after I eat. Instead of burping, it’s like I growl. The air slowly comes back up bouncing off the walls because of the waves caused by ongoing parastlsis when the food has all ready been passed through. Also, my bowl movements are not always regular. Sometimes I do feel constipated when I shouldn’t because my diet is pretty much the same. I have looked at an anatomy book and the colon is located directly in the area that hurts, But I’m not for sure if that is what it is. Please help me figure out what is wrong. I have found several others with my symptoms, but yet they too have not found any diagnosis. I feel so helpless and frustrated.

I asked a question if squatting is the proper way of defecating, and a doctor in this section responded: "So you are blissfully unaware of human anatomy, huh? Putting the knees above the colon would make things much worse. Standing would actually be the best in terms of physiology… however, most people without a toilet would squat so low as to not get **** all over themselves. Or is that too obvious?"

SO, is it anatomy or physiology then that is the issue with squatting? How would putting the knees above the colon make things worse? Because he was able to type that it is self evidently true? How, PHYSIOLOGICALLY does standing change anything for the better? Does he know what the difference between anatomy and physiology is?

Hi, i’m an 18 years old girl, and i just got diagnosed of polyps on my colon.

I think i have actually noticed that something was not normal with my abdomen since about 2 or 3 years ago, cause i noticed that bright red blood occurs several times when i went to the toilet. but i thought it was okay, so i didnt tell my parents yet. and then about 9 months ago, i told my parents about it and we instantly assumed that it was hemorrhoid (since my father and his siblings have had taken hemorrohoid surgery). but then later on this week, i went to the gynecologist because my period circulation is very rapid, and when the doctor check my rectum with his finger, he told me to go to the surgeon because he’s suspicious of the hemorrhoid.

So right after that, I went to my uncle who is a surgeon (he haven’t know about my “hemorrhoid” yet). And then he “slipped in” a tube like sort of thing into my rectum and I don’t know what happened back there but I hear my uncle told my mom and the nurse beside him to look at those little grape like things. Then my uncle said that it wasn’t hemorrhoid but it was polyp. So I have to take surgery, and then after the polyp has lifted, it will be sent into the lab for a test. But my uncle told me that he wants me to go to another surgeon (digestive surgeon to be specific) before operation. And he said that how can you haven’t notice anything about it until today? You should’ve noticed it, since the polyps are not small (he didn’t said that they were big though). And I told him that I noticed the fresh blood and the mucus, but I thought that it was hemorrhoid.

I know that I will get the diagnoses from these doctors, but since I’m just curious and I haven’t made any appointments with another surgeon yet, can you help me with these questions please?
1.Is it possible that my uncle is mistaken? I mean that it really was a hemorrhoid.
2.If it is polyp, can you give a quick diagnose if this polyps are harmless polyps or not (cancer etc)?
3.Is it possible to have a colon cancer at the age of 18?
