The liver has a portal vein as well as a hepatic vein. It also has unique exchange blood vessels similar to capillaries, called “sinusoids.” How do these unique structures determine the function of the organ? • The livers main function is to filter and process the blood it receives. The portal vein and hepatic vein then deliver the nutrient rich blood to the capillaries (sinusoids).
The liver is responsible for hundreds of functions; it is the largest and most complex organ in the body. Weighing in at three pounds it sits behind the ribs on the upper right side of the abdomen and almost covers the entire width of the body. Nutrients and energy, the body 's fuel supply, is processed, converted and distributed by the liver. So, if anything obstructs these processes it will have a serious impact on the body as a whole. And the biggest obstacle would be the presence of gallstones.
The internal environment of the stomach has strong acids and active enzymes that trigger the occurrence of chemical reactions that begin to break down the ingested food. Thereafter, the process of absorption follows, whereas absorption of nutrients occurs in the intestinal tract. The process of absorption is short and is followed by excretion via the cloaca. Similarly, the liver and the pancreas assist in the process of excretion. Additionally, urinary and fecal waste travel through urinary passages and generative canals that connect to the cloaca and are emitted from the cloaca as jelly like, brown droppings.
LIVER ANATOMY AND PHYSIOLOGY The liver is located in the region of the right upper quadrant of the abdomen (usually does not exceed the limit of the costal margin), filling the space of the diaphragmatic dome, where it can reach up to the fifth rib, and is related to the heart through the center phrenic, to the left of the inferior vena cava. It is usually soft and palpable, and is covered by a fibrous capsule. This fibrous capsule applies peritoneum mainsail liver surface (except liver bare area). Is divided into four lobes macroscopically: 1.
The digestive system is responsible for chemically and mechanically breaking down food and includes organs such as, mouth, esophagus, stomach, small intestine, rectum, anus, and additional accessory organs. These organs all aid in the breakdown of food. Food is broken down mechanically by chewing and churning in the stomach, and chemically by acidic enzymes in the stomach and in the small intestine which receives enzymes from the pancreas that are specifically designed for the breakdown of nutrients. Once the food and nutrients are broken down, the excretory system removes whatever the body decides is waste by filtering blood in the nephrons of the kidneys and turning it into urine which is then collected in the bladder and removed from the body when the bladder is
Clinical manifestations that indicate the presence of cirrhosis include the following: fatigue, ascites (fluid accumulation in abdomen), drowsiness and hepatic encephalopathy (Cleveland Clinic Staff, 2014). Room 362’s chief compliant of weakness and drowsiness was displayed upon admission and provided
The primary organs consist of the mouth, throat, esophagus, stomach, and the small and large intestine while the accessory organs are the liver, pancreas and salivary glands. One specific accessory organ peaks a lot of interest and that would be the pancreas but more importantly a disorder associated with it which is called pancreatitis. However, before we can discuss pancreatitis we must first talk about the pancreas and its exocrine functions. Then we
Each of the organ systems in your body have a certain function, or job. Working together, all of these organ systems make up an organism. In other words, cells make up tissues, tissues make up organs, organs make up organ systems, and organ systems make an organism. To begin with, cells are the basic unit of life.
The Digestive System The digestive system is a system consisting of the mouth, oesophagus, stomach, gallbladder, small intestine, large intestine, the rectum and the anus. The functions of the digestive system are: • To break down food particles into molecules for digestion • To absorb into the bloodstream the small molecules produced by digestion • To eliminate un digested and unabsorbed foodstuffs and other waste products from the body The full digestive process begins at the mouth. The food enters the mouth and is chewed.
It is extremely important to look out for symptoms of Marfan syndrome. Scientists have been able to discover the symptoms of the syndrome from experimenting on mice. Symptoms include: flat feet, over-flexible joints, scoliosis, thin face, and a funnel chest. The disease may also effect the lens of the eyes due to the weakness of the ligaments. In addition, this disease may affect several internal organs.
Liver – the human liver has four lobes: right, left, caudate and quadrate. The fetal pig liver has five lobes: right lateral, right central, left central, left lateral, and caudate. Intestines – there is a significant difference in the structure of the fetal pig colon compared to the human colon. The pig colon is spiral. (See p. 45 of the FPDG.)
Lipids are the building block of the structures of cells (Ananya Mandal MD, 2012). The digestive organ found following the stomach is called small intestine, it have three parts, duodenum, jejunum, and ilium. Chyme which is a thick liquid mixture of food that come from stomach is digested here with the help of enzymes, once that is complete it is absorbed by the villi of the small intestinal to be delivered to cell. Even though digestion of carbohydrates and proteins already started in the previous organs, digestion of lipids chemically start once they get in to small intestine. The fat in human diet triacylglycerol (three fatty acids and glycerol) gets emulsified by the aid of bile which is secreted by the liver, it is consistent of bile salt and phospholipids in to small droplets.
Symptoms include: Wide-set eyes Microcephaly: technical term for a small head Low-set ears Epicanthic folds: extra folds of skin on the eyelid Palmar creases (also called a simian crease) High pitched ‘cat cry’ primarily during infancy Hypotonia during infancy Hypertonia in later years Difficulty swallowing Intellectual disability Language development problems Short attention span Hyperactivity and other behavior problems Symptoms that are likely to accompany but are not symptoms for a diagnosis are heart defects, cleft palate and lip, skeletal problems generally in the lower body, and digestive problems. These symptoms may not be harmful or even much of a hassle themselves but can lead to other problems that do cause suffering.
The four systems are the digestive system, the respiratory system, the circulatory system, lymphatic system and the urinary system. The digestive system is divided into two sections i.e. the alimentary canal this is about nine meters long which starts from the mouth and ends at the anus. The second section is the accessory organs these are organs which assist with digestion, absorption and storage of food substances. This includes the pancreas, liver and the gall bladder.
