Urinary system: structure of women and men, functions
The apparatus of the reproductive and urinary systems are closely related and constitute a single structure which is called the urogenital system. Disorders in the urinary system affects fertility and Vice versa. So you should treat them as a whole. Urinary system health is necessary for procreation, excretion of toxins from the body and maintain General health.
What is its function?
Despite the fact that the system of the urinary apparatus of the joint, anatomically and physically, their functions are different. However, the anatomy and physiology of the urinary system are closely interrelated. A disturbance in one element leads to serious problems of the entire apparatus. Due to the urinary system decay products, harmful elements that are found in the urine, toxic substances in a timely manner out of the human body. Involved in this process, the organs of the urinary system.
The principle of operation
Consider how it works urinary system. The urinary system has a complex structure and mechanism. The kidney is a paired organ, performing the function of formation and excretion of urine. In addition, the body regulates blood ph, absorption and distribution of salt and water, synthesizes biologically active substances. Endocrine apparatus of kidney produces the hormone renin. Kidneys are involved in hematopoiesis and in the metabolism of proteins and carbohydrates.
Urine collects in the renal cups, merging, they form the renal pelvis. Through the renal pelvis urine in the ureters, another pair on. The ureter is divided into three sections. Upper section — abdominal, starts from the renal pelvis and passes into the pelvis. The average Department — pelvic, goes into the bladder. Lower division vnutrismennyh is in the bladder. Via the urinary tract, urine enters the hollow organ, the bladder. The bladder consists of smooth muscle fibers are capable of stretching. The epithelial layer of the body has nerve endings which signal the Central nervous system about the filling. There is an act of urination through the urethra. Urination is also controlled by the Central nervous system.
Instincts to reproduce the inherent functioning of the reproductive system. Reproductive system includes the gonads and reproductive organs. Gland produce hormones required for development, maturation, sex differences, and normal functioning of the nervous system. The reproductive system is essential for reproduction.
The structure of women and men
The value and structure of the urinary system in both sexes is almost identical, except that the urethra in men reaches 20 centimeters and in women 5 centimeters. The main task of the kidneys and urinary tract to maintain the fluid balance in the body. Significant differences exist in the reproductive system of men and women. However, they share an important function — procreation. Genitals are divided into external and internal. The outer form of the human body. Authorities which relate to the internal invisible to the eye.
Features of the urogenital system in men
The structure of the genitourinary system males has its own functional characteristics. Urethra in men is arranged so that it performs the excretory function both for urine and for sperm. The urethra, men have ducts and bladder, and testicles. Urine and semen don’t mix due to the anatomical structure and physiological mechanism of switching. The male urethra is divided into posterior and distal (front). One of the important functions of the distal division is to prevent the introduction of infectious diseases in the posterior urethra and spread further in mocambicana body.
To external bodies include the penis and scrotum. As a result of sexual arousal, the body is able to rise, increasing in size and acquire a solid form. The scrotum protects the testes of the male from damage, in addition, maintains the right temperature to produce sperm. The temperature inside the scrotum is lower than body temperature men. The scrotum is darker than the skin on the body, during puberty becomes covered with hair.
In the scrotum testicles. In the testicles sperm are formed and develop into male hormones. What will surprise is that sperm comprise only 10-15% of the seminal fluid. The function of prostate in the development of fluid that makes the sperm active. VAS deferens are involved in removing ejaculate, they also mixed the secret of the seminal vesicles, prostate gland, forming the main part of semen.
The structure of the female urinary system
The structure of the female urethra makes women’s gender more vulnerable to infectious diseases. Female urinary organ shorter and wider than men’s. So it is easy to get infection. Large labia Mature women covered in hair. They protect the urethra and vagina from infection and mechanical stress. The labia are covered with mucous membrane during sexual arousal they fill with blood and become more elastic. The clitoris is structurally similar to the male member during arousal engorged with blood and is responsible for receiving pleasure during sex.
Some women’s bodies belong to the group moving, for example, the ovaries. Their location depends on the location of the uterus and its size. The ovaries synthesize female hormones and contain the ova. Ripe eggs through the fallopian tubes going to the uterus. The uterus is a hollow organ, it is involved in the development of the egg. The development of the egg necessary for conception. If conception has occurred, the fetus develops in the uterus. If fertilization was not ripe oocyte, epithelium of the wall of the uterus and blood is excreted through the vagina. This process is called the menstrual cycle happens every month, a Mature woman. The cervix and vagina are generic and menstrual ways.
Excretory and reproductive system of the child
The urogenital organs are formed the baby while still in the womb. At birth, the function of the urinary system and the function of the reproductive system is formed. However, with the development and growth of the child is the development and growth of the urinary organs. In connection with the modification of the urinary organs, the changes occur in their work. For example, the specific weight of urine at birth is low, over time, the concentration of the urine become more qualitative.
Age features observed in the reproductive system. For example, boys of stunted growth of the testes to 13 years. To 14 years, and the weight of testicles increases to 20 g, and the length 2 times. The full development of the testes reach to 20 years in boys. In girls before 8 years, the ovaries of cylindrical shape, for 11 years becoming an egg shape. At maturity the length and weight of the ovaries increases.
Diseases of the genitourinary system
- ectopic pregnancy;
- diseases transmitted during sexual intimacy;
- kidney failure;
- premenstrual syndrome;
- erosion of the cervix.
Disease in women
Women’s diseases are very dangerous. Chronic inflammation and prolonged infections of the genitourinary system in women can lead to violation of menstruation, urination but the worst part is to infertility or ectopic pregnancy. If there is a symptom of the disease, you should immediately contact your doctor to prevent undesirable consequences and the transition of the disease into a chronic form.
If pathogens increase the number of the woman’s vagina, the disease develops vaginitis, thrush. If the bacteria affect the urethra, there is a disease urethritis. Inflammation of the bladder is called cystitis. As a result of hit of infection in the kidney disease develops pyelonephritis. Hormonal imbalance emerges in various diseases: amenorrhea, dysmenorrhea, premenstrual syndrome. Disease accompanied by pain before, during menstruation, or even the lack thereof.
The disease is characterized by men
Urogenital system of men exposed to the same infections as the urinary system of women. The reason for the occurrence of male diseases are pathogenic microorganisms. Mostly infections are transmitted sexually, the disease develop due to the decreased immunity and poor personal hygiene. Often men develop urethritis, cystitis, prostatitis and pyelonephritis.
Hypothermia or getting infections in the urethra develops urethritis. Inflammation of the prostate — prostatitis, dangerous not only unpleasant sensations, but also the ability to deprive a man to have children. Cystitis and inflammation of the kidneys are not only the fairer sex. Inflammation of the testicles is called orchitis. Inflammation of the seminal vesicles leads to vesicles. Inflammation of the glans and foreskin causing the disease balanoposthitis.
The main causes of pathologies
- dysbacteriosis of the intestine;
- dirty intestines;
- failure of the sex glands;
Preventive measures, treatment
We can conclude that the organism is a single system, and disturbances in one area can lead to completely as it seems at first glance unrelated areas of the body. If there is a symptom, you should consult a doctor to conduct a survey and only in case of confirmed diagnosis to begin treatment.
However, the disease can be prevented by adhering to certain rules. Of hypothermia to prevent. You need to eat a balanced, healthy behaviors. Underwear should be made of natural material, freely to fit the body. Wash genitals on awakening and before sleep, after sex, if possible, after bowel. After intercourse you need to urinate, together with urine out of a possible infection. Lead an active lifestyle, blood and lymphatic stagnation leads to inflammation.
Women should not wear pads daily. You need to wipe the genitals from the pubic area to the anus. The male sex it is necessary to carefully wash the head, pushing the foreskin. Children should not be kept in diapers. After bathing must gently wipe the genitals. Conduct annual preventive examination of the genitourinary system.
