Gastrointestinal Diseases
There are many types of digestive disorders. They are also called gastrointestinal diseases. These include: dyspepsia or indigestion, gastritis, colitis, gastroenteritis, ulcerative colitis and many others. The symptoms of indigestion are: pain or discomfort in the upper abdomen, feeling full or bloated, heartburn, nausea. Indigestion is a common problem and many people have it from time to time.Most people will not need to seek medical advice for their indigestion. However, it can be a sign of an underlying health condition that affects the digestive system.
Ulcers are open sores in the lining of the stomach and small intestine. Alcohol use, cigarette smoking, stress, or poor diet can cause an overproduction of acid. Ulcers are often a result of this excess acidic condition. They may bleed or penetrate the stomach tissue. Ulcers may be treated with medications and diet, but surgery is sometimes necessary.
Gastroenteritis is an infection of the stomach and bowel. The most common symptoms are repeated episodes of diarrhea (three or more episodes within the space of 24 hours) and vomiting. Gastroenteritis can be caused by a virus or by a number of different types of bacteria. Typically, bacterial gastroenteritis develops as a result of food poisoning.
Ulcerative colitis causes the colon to become inflamed (swollen) and in severe cases, ulcers (painful sores) may form on the lining of the colon. These ulcers can bleed and produce mucus and pus. Symptoms of ulcerative colitis can range from mild to severe. They can flare up and then disappear (go into remission) for months or even years. Mild condition can usually be controlled using medication. One in five people with ulcerative colitis have severe symptoms that often respond less well to medication. In these cases, it may be necessary to surgically remove the colon.

2. Reading activities
2.1 Read and translate the text about digestion:
Digestion
During digestion, food is broken down into substances that the blood can carry and the cells can absorb. Carbohydrates bm sugars and proteins are turned into amino acids. Some fats pass into the blood, others become fatty acids and glycerol and pass into the lymph. Body-chemicals called enzymes help these digestive changes. In the small intestine, the now liquid food substances reach the bloodstream. Parts of the small intestine are lined with tiny 'fingers' called villi. These have extremely thin walls, through which the food substances pass into the small vessels of the bloodstream, the capillaries. Other substances pass into the lymph vessels.
The liver is the largest gland in the body, and plays an essential part in digestion. In it, some 500 chemical, processes take place. Through the hepatic portal vein, it receives most of the food substances from digestion. It stores some, and regulates the amount of food that enters the main part of the body's bloodstream.
The pancreas is a large gland. It is located behind the stomach. The pancreas produces hormones - insulin and glucagons. These hormones regulate metabolism of sugars and starches in the body.
The gall bladder is a greenish sac that stores bile.

The Nervous System
The nervous system links us with the outside world and coordinates the activities of the other body systems. The nervous system enables us to respond to stimuli. Together with the endocrine system, the nervous system works continuously to preserve homeostasis.
The two principal divisions of the nervous system are the central nervous system (CNS) and the peripheral nervous system (PNS) The CNS consists of the brain and spinal cord.
The brain is one of the most complicated structures ever been constructed by nature. The outer nervous tissue of the cerebrum is known as cerebral cortex. It consists of folds, ridges and fissures. There are four cavities within the brain. They are called ventricles. The ventricles contain cerebrospinal fluid. This fluid protects the brain and spinal cord from shock.

Thalamus and hypothalamus are two important parts of the brain. Thalamus is a mass of grey matter. It monitors the stimuli we receive by suppressing some of them and increasing others. Hypothalamus regulates many basic body functions, such as sleep, appetite, temperature and some emotions (fear and pleasure).
The PNS includes all of the cranial and spinal nerves. The PNS may be subdivided into somatic and autonomic divisions. Sensory receptors and nerves concerned with changes in the outside environment are somatic. Sensory receptors and nerves that regulate the internal environment are autonomic. The autonomic nervous system regulates the action of the glands, smooth muscles of the hollow organs and the heart. Both systems have afferent nerves,also called sensory nerves, that transmit messages from receptors to the CNS and efferent nerves,also called motor nerves that transmit information back from the CNS to the structures that must respond. The autonomic system has sympathetic pathways and parasympathetic pathways.

Sleep
During sleep, we usually pass through five phases of sleep: stages 1, 2, 3, 4, and REM (rapid eye movement) sleep. We spend almost 50 percent of our total sleep time in stage 2 sleep, about 20 percent in REM sleep, and the remaining 30 percent in the other stages.
During stage 1, which is light sleep, we drift in and out of sleep and can be awakened easily. Our eyes move very slowly and muscle activity slows. People awakened from stage 1 sleep often remember fragmented visual images. When we enter stage 2 sleep, our eye movements stop and our brain waves become slower, with occasional bursts of rapid waves called sleep spindles. In stage 3, extremely slow brain waves called delta waves begin to appear, interspersed with smaller, faster waves. By stage 4, the brain produces delta waves almost exclusively. It is very difficult to wake someone during stages 3 and 4, which together are called deep sleep. There is no eye movement or muscle activity. People awakened during deep sleep do not adjust immediately and often feel groggy and disoriented for several minutes after they wake up. When we switch into REM sleep, our breathing becomes more rapid, irregular, and shallow, our eyes jerk rapidly in various directions, and our limb muscles become temporarily paralyzed. Our heart rate increases, our blood pressure rises. When people awaken during REM sleep, they often describe bizarre and illogical tales dreams.

Depression
Depression is more than simply feeling unhappy or fed up for a few days. Depression affects people in many different ways and can cause a wide variety of symptoms. They range from lasting feelings of sadness and hopelessness to losing interest in the things you used to enjoy and feeling very tearful or anxious. There can be physical symptoms too such as feeling constantly tired, sleeping badly, having no appetite and complaining of various aches and pains.
The severity of the symptoms can vary. At its mildest, you may simply feel persistently low in spirit, while at its most severe, depression can make you feel suicidal and that life is no longer worth living. Many people wait a long time before seeking help for depression, but it is best not to delay. The sooner you see a doctor, the sooner you can be on the way to recovery.

Sensory system
There are five main senses. They are sight, hearing, smell, taste and touch. The visual sensory system is the most important sense organ of man. Almost ninety per cent of the information is supplied to the brain through eyes. The human eye is a spherical organ. Its structure is rather complicated.
Hearing is the reception of sound vibration by the ear. This is the main function of this organ. Another function of the ear is that of providing sense of balance. Auditory sensory system is the second in significance for the normal life of man. The auditory system is subdivided into three parts: the outer ear, the middle ear and the inner ear.
Smell is one of the five senses. It is the nose that performs olfactory response and detects smells by means of the specialized olfactory nerve endings. The receptors of the olfactory sensory system are located in the region of the superior meatuses of the nose. The total number of the olfactory receptors in man is ten million.
Taste is a relatively crude sense. Only four basic tastes can be distinguished: sweet, sour, salty and bitter. Some additional flavours can be determined because of the combination of sense of taste with a sense of smell. Tasting occurs in the mouth where the tongue is lodged. The tongue is covered with papillae that contain cells sensitive to the chemical nature of food.
When we speak of the somatosensory perception we do not only mean the system of skin sensibility but also the sensory system of a skeletomuscular apparatus. They both are capable of responding to touch and perceiving heat, cold, pressure, vibration and pain. Hair covering the human skin also contributes to tactile perception. It is only through physical contact and touch with the objects that we can ascertain their features, such as their size, shape, surface texture and temperature.
