Exercise 3. Read and translate the following information, title it.

The nervous system and the endocrine system are two main controlling and coordinating systems of the body.

The nervous system controls muscle movement and intestinal activity by means of electric and chemical stimuli. So, it controls rapid activities.

The effects of the endocrine system occur more slowly and over a long period of time. The endocrine glands produce chemical messengers, hormones, which have widespread effects.

These two systems are closely connected, because the activity of the pituitary gland is controlled by the nervous system.

Exercise 4. Look at Fig. 24-1 and name all the endocrine glands of males and females.

 

Exercise 5. Read the text.

 

Endocrine Glands

Endocrine glands, or glands of internal secretion, are glands without excretory ducts. They produce special substances called hormones, which are secreted directly into the blood. The hormones are carried throughout the organism with the blood and delivered to various organs whose activity they either stimulate or depress.

Hormones play a very important part in the organism. Many of them affect metabolism and the functioning of the cardiovascular, reproductive, and other systems. A disturbance in the activity of the endocrine glands is accompanied by changes throughout the organism. These changes may be due to an increase in the function of a gland (hyperfunction) or a decrease (hypofunction).

The chemical composition of some hormones is well known. Various hormonal preparations are made synthetically or from the corresponding glands of animals (endocrine preparations). They are widely used in medicine. It should be noted that hormones are substances with very high biological activity.

The endocrine glands include the hypophysis (or pituitary), the epiphysis cerebri (or pineal), the thyroid, the parathyroids, the thymus, the islet part of the pancreas, the adrenals and the incretory part of the sex glands. Each gland consists of glandular epithelial tissue and has an extensive network of blood vessels and large number of nerve fibers (from the vegetative nervous system).

The functions of all endocrine glands are interconnected, and the glands make up a single system. The hypophysis is the chief gland of this system: it produces special substances which stimulate the activities of the other endocrine glands.

The influence of various substances (mainly hormones) acting on the organism through the blood is called humoral regulation.

The activities of endocrine glands are regulated by the nervous system. The nervous system exercises direct control over the endocrine glands through the nervous and neurohumoral control, particularly through the hypophysis. The hormones in their turn affect the functions of different parts of the nervous system.

 

Exercise 6. Make up a plan of the text and retell it.

- How are hormones made?


 




- What are the parts of the endocrine system?

- What is humoral regulation?

Exercise 9. Read and translate the names of different diseases caused by abnormal activity of the endocrine glands.

Goiter (зоб), the enlarged thyroid.

Hyperthyroidism (гіпертиреоз), produces exophthalmic goiter, it leads to loss of weight, nervousness, a rapid pulse, protrusion of the eyes, sweating.

Hyperthyroidism causes cretinism or myxedema because of failure of the thyroid gland.

Hypoparathyroidism causes hypocalcemia. It can lead to tetany (['tetani] - правець).

Addison's disease is caused by failure of the adrenal glands. It is characterized by weight loss, weakness, low blood pressure, brownish pigmentation of the skin, hypoglycemia.

Diabetes insipidus (нецукровий діабет) is characterized by the heavy discharge of urine (polyuria) and intense thirst (polydipsia).

Diabetes mellitus (цукровий діабет), deficiency of insulin prevents sugar from leaving the blood, so it is characterized by excess of sugar in the urine; hunger, thirst and quick loss of weight.

Hyperinsulinism is the excessive secretion of insulin from the pancreas. The patients may be convulsing and fainting.

III. Independent Work: Secretion

 

Exercise 1. Read the text; try to understand it without using a dictionary.

 

Secretion

Secretion is a process generally brought about by an organ called a gland. A gland whether simple or highly complex in structure may be looked upon as a tube, whose walls are composed of highly specialized epithelial cells, gland cells. The tube is closed at one end. In many glands the other end of the lumen opens up, either directly or by means of a special duct, onto a free surface, such as the skin, the interior of the mouth, the lumen of the intestine, etc. The materials produced by the gland are poured onto this free surface, for which reason the secretion of this type of gland is spoken as an external secretion. The gland is surrounded by a dense network of capillaries.

The distinct process may take place in a gland: the gland cell serves merely as a transfer agency, or it acts as a manufacturing plant or both. In the first instance, certain materials, water and NaCl are taken out of the blood stream by the gland cell, transferred through the cell, passed into the duct or lumen, and secreted on a free surface. All types of glands transfer water in this manner. Some glands, e.g. the sweat glands, practically limit their activity to this.

Other glands take certain materials out of the blood stream and chemically transform them into new compounds which together with water and salts are then poured into the duct.

The activity of a gland is normally accompanied by a great dilation of its blood vessels, without this increased flow of blood a gland cannot function for any appreciable length of time. Nevertheless in many instances its blood flow in itself is not the direct cause of secretion, for by administering certain drugs (e.g. atropine) it is possible to stop the secretion completely although the flow of blood continues. Secretion by the digestive glands is to be regarded as an active phenomenon, and not merely a passive filtration.

Text A. Urinary System

 

The urinary system is also called the excretory system, because one of its main functions is to remove waste products from the blood and eliminate them from the body. The other functions are:

- to regulate the volume of the body fluids;

- to balance the pH;

- to balance the electrolyte compositions of the body fluids.

But other systems also eliminate wastes. For example, the digestive system eliminates undigested food, water, salts and bile. The respiratory system eliminates carbon dioxide and water. The skin eliminates water, salts, nitrogen waste.

The urinaiy system includes the kidneys, right and left; two ureters - long tubes, which lead to the lower part of the urinary bladder; the urinary bladder, which is a hollow sac for temporary collection of the urine; and the urethra - the tube, through which the urine is discharged from the bladder and passes out of the body.

 

Text B. Kidneys

The kidneys are considered to be the main organs of the urinary system. They are two in number, right and left. The kidneys are bean-shaped organs embedded in a cushion of adipose


Fig. 25-1. The urinary system


Fig. 25-2. The kidney


 

tissue and located behind the abdominal cavity. They consist of outer cortex part, inner medullar part, and pelvis. The kidneys can be compared with filters, as they perform the filtration of waste products from the blood.

These waste products go to the kidney through the renal arteries, rather short and thick vessels.

The location of the urinary organs and their blood supply can be seen in Fig. 25-1.

The kidney is an organ about 10 cm long, 5 cm wide, and 2.5 cm thick. On the inner margin there is the hilus (ворота), at which the renal artery and vein, and the ureter connect with the kidney. The renal cortex covers the kidney. The renal medulla contains the tubules that collect urine. These tubules form pyramids with the tips toward the renal pelvis. The renal pelvis is a funnel-shaped basin that forms the upper part of the ureter. Calyx ['keeliks] is a cuplike extension which surrounds the tip of pyramids and collect urine, which then passes down the ureter and bladder (Fig. 25-2).

 

Text C. Nephrons

The nephron is the smallest unit of the kidney. It is a tiny coiled tube with a bulb [ЬлІЬ] at one end. This bulb is called Bowman's capsule (капсула Боумена). which surrounds the glomerulus. Each kidney contains about 1 million nephrons. The afferent artetiole supplies the glomerulus with blood; the efferent arteriole carries blood from the glomerulus. (The detailed structure of the nephron can be seen in Fig. 25-3.)

The process of filtration and formation of the urine takes place within the tiny tubules of the kidneys.


Text D. Functions of Kidneys

The kidneys are involved in the following processes:

1. Excretion of unwanted substances such as waste products from cell metabolism, excess salts, and toxins.
