In anatomy, sphincter is the name given to an annular muscle located in the orifice of a body cavity, and whose function is to open and close, preventing or allowing the passage of a substances (such as secretion) outside or into the cavity. This way, the sphincter may close to retain substances within the body or a specific body organ, or may open allowing these substances to pass from one organ to another, or to be expelled from the body. According to several specialized publications, there are more than fifty sphincters in the human body. Next, we will offer you some information about sphincter control and some sphincters our body has.
What is Sphincter control?
Sphincter control is the human capacity to relax or contract sphincter muscles at will, although as we will see later, there are some sphincters we do not voluntarily control. Anal and bladder sphincter control is perceived as particularly important by people, considering they prevent us from the unexpected urine and fecal matter excretions. As such, much emphasis is placed on control of the sphincter during early childhood, when it is necessary kids to develop a control over their bowels. Generally, children begin to develop this capacity between 18 and 24 months. On other hand,

Actually, there are two of them, a lower esophageal sphincter (LES) and an upper esophageal sphincter (UES). According to experts, the LES is a bunch of muscles located at the low end of the esophagus (where it meets with the stomach) and prevents stomach content, acid, among other substances, from returning from the stomach to the esophagus. In turn, the UES is also a collection of muscles located at the top of the esophagus. These are consciously controlled muscles, which prevent food and secretions from going down the trachea (windpipe). We use them when vomiting, belching, eating or

Rectum is a chamber that contain around 8 inch of tube, the rectum are connected to the large intestine and anus. Rectum have a function of release the unnecessary product.
The main purposes of the colon are to absorb water and electrolytes to compact the feces for expulsion and expulsion of the feces. The length of the colon is roughly one to one and a half meters and the diameter spans from two to eight centimeters. The colon is made up of seven sections. These sections are the cecum, the ascending colon, the transverse colon, the descending colon, the sigmoid colon, the rectum and the anal canal.
A common condition that is associated with GERD and LES problems is having a hiatal hernia. A hiatal hernia is when you have a larger than normal opening in the diaphragm where the esophagus passes through. Since this opening is larger, the stomach begins to enter this opening. When you eat, the stomach and esophagus do not join as they were properly intended and cause malfunctioning of the LES. In some cases, food remains above the LES allowing it to easily travel back up the esophagus.
...ve eaten, to break down the food into a liquid mixture and to slowly empty that liquid mixture into the small intestine. Once the bolus has entered your stomach it begins to be broken down with the help of the strong muscles and gastric juices which are located in the walls of your stomach. The gastric juices are made up of hydrochloric acid, water, and mucus- and the main enzyme inside of your stomach is what is known as pepsin, which needs to be surrounded in an acidic setting in order to do its job, that is to break down protein. Once the bolus has been inside of your stomach for long enough it begins to form into a liquid called chyme, and what keeps the chyme from flowing back into our esophagus are ring shaped muscles known as sphincters located at the beginnings and ends of the stomach and they have the task of controlling the flow of solids and liquids.
The Spleen by Anne Finch, the Countess of Winchelsea, presents an interesting poetic illustration of depression in the spleen. The spleen for Finch is an enigma, it is mysterious, shape-shifting, and melancholic. Melancholy leads the subject to flashes of a grander, terrifying emotion: the sublime. The subject of Finch’s Pindaric ode experiences the sublime, and yet has the uncanny ability to reflect and reason on the feeling with acuity--even though the subject suffers from depression, which in effect dulls sensory information. The fact that she intensely perceives the sublime suggests a paradox where dulled senses can produce a penetrative emotional episode. To understand the paradox, the theory of the sublime and Finch’s engagement with the sublime in The Spleen must be traced to conceive the state of the dulled mind in the thrall of an infinite, and transcendent wave of emotion. The focus of this essay is that Finch understands that Dullness, as a by-product of depression, enables rational thought during a sublime experience. Furthermore, she thus illustrates her experience through images where she emphasizes her sensory information and her feelings, which were supposedly numbed by depression. Her feelings, indicated in The Spleen, are the crux to how Finch is able to simultaneously feel numb, and process the sublime.
Imagine you are eating a sandwich containing wheat bread, ham, lettuce, and Swiss cheese. Do you ever wonder where the nutrients go from all of the previous listed ingredients? Well, when a bite of this sandwich is taken, the mouth produces a saliva enzyme called amylase. This enzyme immediately goes to work by breaking down the carbohydrates that are in the bread. Once, the bite is completely chewed, the contents then are swallowed and go down the esophagus and begin to head towards the upper esophageal sphincter and the is involuntarily pushed towards the stomach. The next passage for the sandwich is to go through the lower esophageal sphincter; which transports the sandwich into the stomach.
The spleen, also referred to as “the forgotten organ”, is located lying below the diaphragm and next to the stomach in the upper left quadrant. It is an intraperitoneal organ that is very large and composed mostly of lymph tissue. The proper function

Stress incontinence is leakage that occurs when an activity places stress or pressure on the bladder. Sneezing, heavy lifting, coughing, exercising, getting out of a car, laughing and getting out of bed are common triggers for stress incontinence. The second type is called urge incontinence and is sometimes referred to as an overactive bladder. Urge incontinence strikes suddenly and is an uncontrollable need to empty the bladder. It is often described as a miscommunication between the bladder and the brain. Urge incontinence can be triggered by dreaming, hearing water running, dealing with a locked door or drinking even a small quantity of

...urpose is to clean the urethra of harmful bacteria and other substances prior to ejaculation. The penis, not composed of muscle or bone, is the next step for the sperm. It’s three main purposes are to transport urine, transport semen, and to provide sensation. Inside the penis is the urethra. The urethra’s functions are to carry urine from the bladder to outside the body, and to ejaculate semen during sexual intercourse. The tip of the penis is called the scrotum, and it’s three main functions are to act as a thermometer for the testicles, protect and hold the testicles, and to provide various sensations.
The key to toilet training a child is choosing the right time carefully. It is hard to determine when the right time is to toilet train a child but do not try to toilet train a child during transitional or stressful times. Do not try to toilet train a child if it is during a time when the child is moving from one home to another, going on vacation, there is a new baby, or parents going through a divorce. Try to postpone toilet training until one month after the transitional time. Children can learn things better like how to use the toilet if they are relaxed and on a regular routine.
The digestive system is a very important system in the human body. It is a group of organs that work together to turn food into energy and nutrients in the entire body. The food that was chewed in a humans’ mouth now passes through a long tube that is inside of the body that is known as the alimentary canal. The alimentary canal is made of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Those few things are not the only important accessories of the digestive system there is also the teeth, tongue, salivary glands, liver, gallbladder, and pancreas.
The excretory system, which includes the rectum and anus helps the digestive system by getting rid of waste and the digestive system helps the excretory system by breaking down food to be eliminated from the body. Wow! The human body wouldn’t be able to work without one or the other. Anyways, I hope you enjoyed reading my journey throughout the human digestive system. I hope to write again from where my next journey from here will begin- perhaps it will be in the ocean or along Sydney Water pipes. Until next
