^f TheDigestiveSystem, . .

~ - 'Yhn^r ₈'>■' - '

The digestive system consists of the digestive tract and digestive glands.

The digestive tract is some 8—10 m long and is divided into the follow­ing parts: oral cavity, pharynx, oesophagus, stomach, small intestine and large intestine. The structures of the different parts of the tract have some special features.(}/ ff-_i((, j. </sru^**^

The wall of the greater part of the digestive tract consists of three tfoats: internal - mucous, middle — muscular, and the external — serous. The mucous coat is lined with the epithelium outside which is a connective tissue with a thin layer of smooth muscle fibres. The mucous coat is pink in colour because it has many blood vessels. The numerous small glands in this coat secrete a viscous coat of the digestive tract. It facilitates the movement of food and protects the mucous coat from the damage by solid particles of food and various chemical substances. One must re­member that the mucous coat of the digestive tract begins with the esoph­agus, contains lymph nodules which also have a protective function.

The greater part of the muscular coat of the digestive tract consists of two layers: an internal layer with circular muscle fibres and an external layer with longitudinal muscle fibres. The wall of the pharynx and the superior part of the esophagus, and the tongue and the soft palate all contain striated muscle tissue. It is the muscular coat of the other parts of the digestive tract that consists of smooth muscle tissue. Contractions of the muscular coat move food along the digestive tract.

The serous coat that covers the digestive organs in the abdominal cavity is called the peritoneum. The peritoneum has two layers, visceral and parietal. In the esophagus the serous layer is lacking and the outer coat is fibrous in nature. , , ,

The digestive glands secrete digestive juices that contain enzymes and some other substances which take part in the chemical processes of digestion.

In addition to the small glands in the mucous coat of the digestive tract, there are also large glands: the salivary glands, the liver and the pancreas. Though these glands are situated outside the digestive tract, they communicate with it through ducts.

Any part of the digestive tract and the digestive glands are equipped with nerve fibres and their endings. The nerves of the digestive glands regulate the secretion of digestive juices. It is known that the nervous system not only regulates the activity of each organ, but also coordi­nates their activities.

Упражнение 5. Прочтите каждое суждение. Найдите в тексте В предло­жения, более полно выражающие мысль данного суждения, и прочти­те их.

1. The digestive tract is divided into some parts. 2. The viscous coat of the digestive tract facilitates the movement of food. 3. The muscles of different types form the walls of the intestine. 4. The serous coat doesn't cover all the oigans of the digestive system. 5. Enzymes take part in digestion. 6. Salivary glands, liver and pancreas are situated outside the digestive tract. 7. The nervous system regulates and coordinates the work of the digestive organs.

/ ' - V ^f' Т1>еUrinary System

1. The uriuary system is the system which excretes the largest part of the waste products of the body. It consists of the kidneys, right and left, the ureters, a tube from each kidney which conveys the urine to the bladder, the urethra, a tube that leads from the bladder, along which the urine is passed out of the body.

2. The kidneys («renes» — Latin) are placed one on each side in the lumbar region of the spine, on the posterior abdominal wall, at the level of the twelfth thoracic and first-second lumbar verte­brae. A kidney weighs about 150 grams and is covered by membranes. The connective tissue membrane which di­rectly adheres to the kidney is called the fibrous capsule. This capsule is surrounded by perirenal fat and is called the adipose capsule. The kidneys are two bean-shaped organs. The kidneys contain one mil­
lion small tubes, which have to excrete products of metabolism and con- I rol the concentrations of most of the constituents of body fluids. These small tubules make up the parenchyma of the kidney. They are very fine and may be of various shape. Since dissolved (растворенные) wastes may be excreted by diffusion through the various cell membranes there is little evidence that such excretion occurs.I ^ Г

3. The inner margin of the kidney is known as the hilus. At the hilus (he ureter which conveys urine is a tube about 30 cm long. When the ureter leaves the hilus it descends along the posterior abdominal wall into the cavity of the pelvis where it perforates the wall of the bladder and opens into its cavity. As the muscular coat of the ureter contracts it has to perform peristaltic movements. ^

4. The bladder is a reservoir for urine. It is situated in the cavity of the pelvis. The bladder has three parts: the superior part or apex, the middle part or body, and the inferior part or fundus. The wall of the bladder consists of three coatings — mucous, muscular and connective tissue. The mucous membrane of the bladder forms numerous folds. If the bladder fills, the folds of thevjnucous coat will straighten out. The mus-

V V ... -

cular coat consists of three layets of smooth muscles which are able to extend in different directions. It should be known that the capacity of the bladder of an adult is about 350—500 ml. JW>j^ fa,

I ^JTheKidneys

' I

Kidneys are a pair of glands which are situated close to the spine in the upper part of the abdomen. They are on a level with the last dorsal and upper two lumbar vertebrae. I They are kept in this position by a quantity of fat, l&ose &6nnective tissue, in which they are embedded, and the large vessels which have to supply them with blood. ¹" ' /

Structure. In size each kidney is about 4 inches long, 2 and 1/2 inches wide, 1 and 1/2 тШthick, and weighs over 4 ounces] The size, however, may vary a good deal. The left kidney is slightly longer and narrower, and lies a little higher in the abdomen than the right. | Since the outer margin of the kidney is convex, the inner is concave.j It presents a deep depression, which is known as the hilus, where the vessels enter its substance./At the hilus the renal vein lies in front of the renal artery, the former joins the inferior vena cava, and the latter springs from the aorta almost at a right angle. ^v V ^r

| Vertical s$;fion through a kidney allows to disclose three concentric sonqL The outer light-coloured zone is the renal cortex, within this is the darker renal medulla and within this again is a space — the renal sinus which is i^rmajlv occupied by fibrous sac, the renal pelvis. The cortex extends inward in a series of renal columns which divide the medulla into a number of renal pyramids. ^

Within the cortex each minute artery presents a vascular knot, a glomer­ulus. Each glomerulus projects into the end of its corresponding renal tubule, which is separated by a thin layer of cells, glomerular (Bowman's) capsule;

Hlomerulus plus capsule forms^a renal (Malpighian) corpuscle. A renal cor­puscle with tubules and blood vessels is called a renal unit, or nephron.

Function. ^Эпеchief functipn of the kidneys is to separate fluid and certain solids form the bloodjjfTie glomemy^s t^filter from the blood the non-protein portion of the plasma./t is estimated that in 24 hours the total human glomeruli will be able to filterjfegtween 150 and 200 litres, 99 per vent of which is reabsorbed by ffiemjbu^ j

The kidneys are to be regardicKtis filters through which the whole hlood of the body passes and which remove from the blood a substance, urea, together with other impurities, which together constitute tlje urine. I he cleansed blood passes on in its vessels, and the urine ^ffl^into the ureters and finally into the bladder. If the kidneys cealse io work the blood will become poisons because of the accumulation of the waste matters. ^ , ^ ^
