HOW
YOUR ARSE WORKS
Rectum anal canal & arsehole / Shitting / Sensation to enlargement pain & touch / Complications Diarrhoea / Constipation / Haemorrhoids (piles) / Dietary advice Your arse is just the beginning, or rather the end, of your digestive and waste disposal system. This is one of the most important functioning parts of our bodies, which extracts nutrients and goodness from the food we eat and then gets rid of the waste. Many people believe that this is just a small tube linked to the stomach where shit sits waiting for the rectal express to the toilet via your arse. If you're anything like this, your digestive system is about 27 feet (8m) short. In fact, from mouth to arsehole, it's a 30-foot (9m) long canal, regulated by a series of canal locks and chambers, and lined with muscles that massage the food and waste along. After eating, food can spend anything up to 6 hours in the stomach, a 'J' shaped organ about 14 inches (35cm) long. Here, acids and enzymes digest food until it becomes a semi-liquid soup that you've seen from time to time as vomit with diced carrots. The speed at which food leaves the stomach depends on what you've eaten and what's going on further down the line. Nerves connect the arse to the stomach and vice versa and transmit messages to control the flow of food and waste. For example, you may experience discomfort or pains in your stomach if you are constipated or being fucked or fisted. Conversely, when you eat, quite often you want to go for a shit. Only in a semi-liquid form is the food passed on to the next stage of digestion the small intestine, a rubbery tube, an inch (2.5cm) wide and some 21 feet (6.5m) long. This is made up of the duodenum 10 inches (25m), the jejunum 10 feet (3m) and ileum 13 feet (4m). Although these sections of your intestine are all slightly different in what they do, it's here that the nutrients and goodness in food are extracted. What remains resembles a rich vegetable
soup, which passes into the large intestine. This is rather
like an inverted 'U' shaped pipe, 6 feet (2m) long, which joins
the small intestine at the bottom right hand corner, near your
appendix. This is made up of four sections: the ascending, transverse,
descending, and sigmoid colons. Here, much of the water and
salt from the waste is absorbed back into the body as it passes
through and consequently the shit becomes more solid. By the
time it leaves the sigmoid colon and reaches the rectum, shit
is normally in discrete turds of a good consistency and reasonable
size. Shit in the rectum leaves by way of the anal canal and
finally your arsehole. The sigmoid colon is best described as
the final packaging and holding bay, the rectum is the dispatch
area and the anal canal to your arsehole is the main gate. This
is achieved by good muscle control much of which we know little
about and yet it hopefully lasts us an entire lifetime.
Around the connecting tube between your sigmoid colon and rectum is a ring of muscle that angles the tube in such a way as to close it off. This (sphincter) muscle regulates the waste leaving the sigmoid colon; without it, your rectum would fill up continuously and you'd be shitting all the time. Your rectum is a stretchy 4-5 inch (10-13cm) muscular tube that can stretch to the size of a clenched fist (when full of shit) or a hand. Below your rectum is the anal canal, 1-2 inches (2-5cm) long, which ends in your arse hole. The surface of the rectum and the anal canal is usually covered with a thin layer of mucus or natural lubricant designed to help with shitting and which also helps offer protection from infections. If you rub the surface, you quickly exhaust the supply of mucus, which is why you need additional lubricant when putting anything up the arse. At the bottom of the anal canal, is another sphincter muscle made up of two smaller interconnected rings of muscle. One of them is not under your direct control but responds to internal body messages; for example, when the rectum is full or when you cough - the muscle tightens. When the muscle doesn't work properly you leak. You have more control over the other muscle, which you can relax or tighten at will. Try it now - you see control is everything. The weight of shit stretching the sides of the sigmoid colon signals the top sphincter muscle to relax briefly allowing a measured amount into the rectum. This is also called a movement. If you're ready to go and usually sitting on a toilet, the bottom sphincter muscle relaxes and lets the shit down the anal canal and out through your arse hole. SENSATION TO ENLARGEMENT PAIN & TOUCH The rectum only senses enlargement and stretch, whilst the anal canal can sense temperature, touch and pain. This makes the anal canal more fun to play with than the rectum, which will only notice if you stretch its walls. Above the rectum there are no receptors to sense pain or injury so penetration beyond this point is more risky. To the front of the rectum (tummy side) is your prostate gland, doughnut-shaped and about the size of a chestnut. This is very sensitive to pressure and harpoon guns. At orgasm, it releases fluid and nutrients in which sperm swim and live. There are many factors involved in shitting property and many of these can go wrong. If your sphincter muscles don't seal properly then you may leak or shit yourself. Ulcers or a split in the anal canal may mean you get pain and a tighter sphincter muscle. If you regularly use laxatives, you may damage the nerve supply to this area and then either get diarrhoea or constipation. If you experience anything out of the ordinary or have any concerns - go to a doctor. Prevention or early treatment is preferable to suffering, or getting serious complications needing surgery. Diarrhoea is usually caused by an irritation of the intestine lining or infection in your small or large intestine. Quite simply, your body wants to get rid of whatever the problem is and, if it can't vomit it out, it needs to get it through your system as quickly as possible. The little muscles that massage your food along go into over-drive (which is what can cause stomach aches, pain and cramps). The locks and valves regulating the flow of your digestive system open up to help flush-out infections or irritants and your body is so desperate to get rid of it that it doesn't have time to extract the water from your turds. It's at times like this that your open to release that all too familiar brown sludge. Oddly enough, we sometimes underestimate our body's ability to deal with situations like this. Generally, speaking, it is best to let nature take its course - not forgetting to drink lots of fluids (containing salt and sugar) to help wash out your digestive system and prevent dehydration However, if symptoms persist - get it checked out. Constipation can be caused by spasms in the large intestine, insufficient bulk or roughage in your diet, lack of exercise or stress. Shit passing through the colon - which extracts just enough water to turn the sludge into solid turds, can get stuck there where they continue to 'dry out' until they become hard and knotted. Shitting is then painful as the hardened turds rub abrasively against the walls of your colon, rectum and anal canal. Haemorrhoids are veins near the surface of the bottom part of your anal canal that have become inflamed, forming pockets or bags of blood. Initially, they'll stay inside but they can, over time, get larger and be pulled towards your arse hole by the downward motion of shitting. If constipated, straining makes them much worse. Sometimes they split open and can bleed, often quite profusely. Lowering stress levels, taking regular exercise and a balanced diet will all play important roles in helping to ensure that your digestive system works well and is problem free. Dietary advice to prevent constipation is based on the effects of certain foods being able to resist digestion. Such foods increase the weight (and volume) of shit, and are also able to bind water more effectively, forming a turd that is softer, and easier to shit from the body. Fruit and vegetables, both cooked and raw, whole-grain cereal products such as brown rice, wholemeal bread, flour products and whole-wheat breakfast cereals are excellent turd-bulking agents and the maxim is the more the merrier. Pulses, such as lentils and beans, are also known to be effective, although the novice may become rather farty and will need to adjust intakes accordingly. The addition of bran to the diet (along with sufficient fluid intake) can provide some relief from constipation, although this should not be a substitution for a healthy diet. Diets which are more likely to lead to constipation include dairy products, fatty foods and foods which have little or no fibre. If you experience pain, discomfort, if you're not shitting softish turds regularly or if you have any concerns - visit your doctor. Some (GUM/STD) clinics also offer advice and information on diet and healthier living. |
