This medical animation shows laparoscopically assisted gallbladder removal surgery, or cholecystectomy. The animation begins by showing the normal anatomy of the liver and gallbladder. Over time, gallstones form within the gallbladder, blocking the cystic duct, and causing the gallbladder to become enlarged and inflamed. The procedure, sometimes called a "lap-chole", begins with the insertion of four trocar devices, which allow the physician to see inside the abdomen without making a large incision. Air is added to the abdominal cavity to make it easier to see the gall bladder. Next, we see a view through the laparascope, showing two surgical instruments grasping the gallbladder while a third severs the cystic duct. After the gallbladder is removed, the camera pans around to show that the cystic artery and vein, have already been clipped to prevent bleeding.

A thyroid biopsy is a procedure in which a small sample of tissue is removed from the thyroid gland and looked at under a microscope for cancer, infection, or other thyroid problems. The thyroid gland is found in front of the windpipe (trachea), just below the voice box (larynx). A sample of thyroid tissue can be taken by: Fine-needle biopsy. Your doctor puts a thin needle through the skin and into the thyroid gland. Many thyroid specialists like to use a needle biopsy method rather than surgery. Open biopsy. Your doctor makes a cut (incision) through the skin to see the thyroid gland. This method is done when other tests have not found the cause of your symptoms. Core needle biopsy. Your doctor inserts a needle with a special tip and removes a sample of tissue about the size of a grain of rice.
Prompted by the hormone prolactin, the alveoli take proteins, sugars, and fat from your blood supply and make breast milk. A network of cells surrounding the alveoli squeeze the glands and push the milk out into the ductules, which lead to a bigger duct.
An abdominal aortic aneurysm is an enlarged area in the lower part of the aorta, the major blood vessel that supplies blood to the body. The aorta, about the thickness of a garden hose, runs from your heart through the center of your chest and abdomen. Because the aorta is the body's main supplier of blood, a ruptured abdominal aortic aneurysm can cause life-threatening bleeding. Depending on the size and the rate at which your abdominal aortic aneurysm is growing, treatment may vary from watchful waiting to emergency surgery. Once an abdominal aortic aneurysm is found, doctors will closely monitor it so that surgery can be planned if it's necessary. Emergency surgery for a ruptured abdominal aortic aneurysm can be risky.
What Is Phonemic Awareness, Reading Program For Kids, Phonics For Children, Teach Your Baby To Read---- http://children-learning-reading.good-info.co----- What is Phonemic Awareness, Phonemic Awareness is defined as the ability to identify, hear, and work with the smallest units of sound known as phonemes. It is NOT the same as phonological awareness, instead, it is a sub-category of phonological awareness. For example, phonemic awareness is narrow, and deals only with phonemes and manipulating the individual sounds of words - such as /c/, /a/, and /t/ are the individual sounds that make up to form the word "cat". Phonological awareness on the other hand, includes the phonemic awareness ability, and it also includes the ability to hear, identify, and manipulate larger units of sound such as rimes and onsets. Phonemic awareness can be taught very early on, and will play a critical role in helping children learn to read and spell. While it's not set in stone on when a child can learn to read, however, I do believe that a child that can speak is a child that can learn to read. Children as young as two years old can learn to read by developing phonemic awareness, and they can learn to read fluently. Please see a video of a 2 year old (2yr11months) reading below. Below are several of the most common phonemic awareness skills that are often practiced with students and young children: Phonemic identity - being able to recognize common sounds in different words such as /p/ is the common sound for "pat", "pick", and "play". Phonemic isolation - being able to recognize the individual sounds of words such as /c/ is the beginning sound of "cat" and /t/ is the ending sound of "cat". Phoneme substitution - being able to change one word to another by substituting one phoneme. For example changing the /t/ in "cat" to /p/ now makes "cap". Word Segmenting - the parent says the word "lap", and the child says the individual sounds: /l/, /a/, and /p/. Oral blending - the parent says the individual sounds such as /r/, /e/, and /d/, and the child forms the word from the sounds to say "red". Studies have found that phonemic awareness is the best predictor of reading success in young children. Research has also found that children with a high level of phonemic awareness progress with high reading and spelling achievements; however, some children with low phonemic awareness experience difficulties in learning to read and spell. Therefore, it is important for parents to help their young children develop good phonemic awareness. Being able to oral blend and segment words helps children to read and spell. According to the National Reading Panel, oral blending helps children develop reading skills where printed letters are turned into sounds which combine to form words. Additionally, word segmenting helps children breakdown words into their individual sounds (phonemes), and helps children learn to spell unfamiliar words. As a young child begins to develop and master phonemic awareness skills, they will discover an entirely new world in print and reading. You will open up their world to a whole new dimension of fun and silliness. They will be able to read books that they enjoy, develop a better understanding of the world around them through printed materials, and have a whole lot of fun by making up new nonsense words through phonemic substitutions. For example, we taught our daughter to read at a young age - when she was a little over 2 and a half years old. Before she turned three, she would run around the house saying all types of silly words using phonemic substitution. One of her favorite was substituting the letter sound /d/ in "daddy" with the letter sound /n/. So, she would run around me in circles and repeatedly say "nanny, nanny, come do this" or "nanny, nanny, come play with me" etc... Of course, she only did this when she wanted to be silly and to make me laugh, at other times, she would of course properly refer to me as "daddy", and not "nanny". She is well aware of the differences between these words and is fully capable of using phonemic substitution to change any of the letters in the words to make other words.

Lip augmentation is a cosmetic procedure that can give you fuller, plumper lips. These days, an injectable dermal filler is the most commonly used method of lip augmentation. There are many types of dermal fillers that can be injected in your lips and around your mouth.
What is the spleen and what causes an enlarged spleen (splenomegaly)? The spleen sits under your rib cage in the upper left part of your abdomen toward your back. It is an organ that is part of the lymph system and works as a drainage network that defends your body against infection. White blood cells produced in the spleen engulf bacteria, dead tissue, and foreign matter, removing them from the blood as blood passes through it. The spleen also maintains healthy red and white blood cells and platelets; platelets help your blood clot. The spleen filters blood, removing abnormal blood cells from the bloodstream. A spleen is normally about the size of your fist. A doctor usually can't feel it during an exam. But diseases can cause it to swell and become many times its normal size. Because the spleen is involved in many functions, many conditions may affect it.
Hepatitis B is a serious liver infection caused by the hepatitis B virus (HBV). For some people, hepatitis B infection becomes chronic, meaning it lasts more than six months. Having chronic hepatitis B increases your risk of developing liver failure, liver cancer or cirrhosis — a condition that causes permanent scarring of the liver. Most people infected with hepatitis B as adults recover fully, even if their signs and symptoms are severe. Infants and children are more likely to develop a chronic hepatitis B infection. A vaccine can prevent hepatitis B, but there's no cure if you have it. If you're infected, taking certain precautions can help prevent spreading HBV to others.
our uterus (or womb) is normally held in place inside your pelvis with various muscles, tissue, and ligaments. Because of pregnancy, childbirth or difficult labor and delivery, in some women these muscles weaken. Also, as a woman ages and with a natural loss of the hormone estrogen, her uterus can drop into the vaginal canal, causing the condition known as a prolapsed uterus.
Thyroid nodules are solid or fluid-filled lumps that form within your thyroid, a small gland located at the base of your neck, just above your breastbone. The great majority of thyroid nodules aren't serious and don't cause symptoms. Thyroid cancer accounts for only a small percentage of thyroid nodules. You often won't know you have a thyroid nodule until your doctor discovers it during a routine medical exam. Some thyroid nodules, however, may become large enough to be visible or make it difficult to swallow or breathe.
