Excretion Organ

Excretion is the process of spending one substance from the body. Excretion is the process of spending the rest of metabolism like urine, sweat, and breathing. There are 4 tools excretion in humans, kidneys, skin, liver, and lungs. Kidneys secrete urine, skin secretes sweat, heart secretes bile together with urine, and the lungs remove carbon dioxide and water vapor.

Kidney
Kidney is one excretion organ in humans are located in the rear of the abdominal cavity , the right of the left pubic bone . Kidney consists of three layers. Outer part called the cortex (kidney skin), underneath there modularly (marrow kidney) , and on the inside a cavity called the renal pelvis (kidney cavity). Kidney function associated with renal excretion system is to filter the blood and excreted in the form of urine. There are three stages the formation of urine filtration (blood filtering), reabsorption (reabsorption of useful substances in the urine), and augmentation (urine collection). Urine from the kidneys and then to the ureters, bladder , and then expelled from the body through the urethra.

Skin
Skin is a tissue found on the outer parts of the body. Skin consists of a network of the epidermis, the dermis (the cuticle), and connective tissue under the skin. Functions associated with the skin are to sweat excretion system. Sweat was issued to regulate body temperature. Sweat is produced in sweat glands located in the dermis layer. Sweat contains salt solution, urea, and water. Factors affecting the amount of sweat is comes out of activity of the body, the temperature of the environment, food, health, and emotions.

Liver
Liver is an important part of the digestive system. Liver function associated with the system is removing sap bile excretion and urea. Bile is produced from the sap of red blood cells overhaul. The sap is stored in the gall bladder and then distributed to the intestine 12 fingers. Sap bile consists of bile salts and bile pigments. Bile salts serve as a fat emulsifier. Whereas bile pigments useless and should be excreted. The substance is absorbed by the blood and will exit through blood filtration in the kidney. That's what makes often colored urine. In addition, bile pigment is also coloring the stool.

Lung
In addition to functioning as an important organ in the respiratory system , the lungs also serves as one tool excretion in humans . Waste materials must be removed by the lungs are carbon dioxide and water vapor. Inhale oxygen from air by nose only just taken the lungs to the blood, while the residue in the form of carbon dioxide and water vapor released by the nose again. The process of oxygen binding and release of carbon dioxide by the blood occurs in the alveoli. Alveolus is part of the lungs in the form of small bubbles.

Hi,

Healthline.com recently launched a free interactive "Human Body Maps" tool. I thought your readers would be interested in our body map of the kidney: http://www.healthline.com/human-body-maps/kidney

It would be much appreciated if you could include this tool on http://organ.health-tips-diseases.com/2013/09/excretion-organ.html and / or share with friends and followers. Please let me know if you have any questions.


Thank you in advance.
Warm Regards,

Human Organs

Image
The human organs is drawn such as on the picture belows: Each organ have certain function to our body, if there is a disturbance to certain organ function the body will feel inconvenience and actually the nerve will give an alarm through the network and will sent to the brain. Our brain than should think about what the abnormal condition, and should have any solution to maintain an abnormal situation.

Nose

The nose, the site of the sense of smell is the organ through which mammals take in air. It is supported by cartilage and bone, covered with skin , lined with a mucous membrane, and provided with muscle. A nasal septum divides it into passages, each of which begins with a vestibule and contains a respiratory and olfactory region. The lining of the vestibule is continuous with the skin and contains hairs, sweat glands, and sebaceous (oil producing) glands . The respiratory region includes nearly all of the septum and the lateral walls of the nose. Goblet cells, which produce and secrete a watery mucus, are present in the lining, as is a type of erective tissue, composed of large, thin-walled veins whose blood supply serves to warm incoming air. The olfactory region is located on the superior concha and adjacent septum. Olfactory cells are present in its lining and have delicate, slender process (modified cilia) at their free surface. Odors from chemicals in the air are received by

Nervous System on Sole of Foot

Image
The palms of the hands and the soles of the feet have some sweat glands than any other part of body. Excessive hand sweating is the most common sweating problem, sweaty hands usually come along with sweaty feet. When sweaty hands and feet become a severe problem, they are called palmar hyperhidrosis and pedal hyperhidrosis respectively. This tend happen begin in early childhood and become worse after teenage years and early adulthood. The sweaty hands and feet are likely to develop cracking and scaling of the skin, blister, frostbite , warts and fungal infections . According to traditional Chinese medicine, the spleen system controls the muscles and the limbs, the four extremities must be nourished by the nutrient essence transformed and transported by the spleen. Several nervous system on the sole of foot as on the picture below:

Muscle

Muscle tissue, which comprises about 40 percent of human body weight, consist of threads, or muscle fibers, supported by connective tissue. All living cells can move to some degree, but this ability is highly developed in muscles, which act by fiber contraction; the fibers can shorten to two thirds of their resting length. Muscle vary greatly in structure and function in different organs and animals. Based on structure there are two types of muscles; smooth and s treated, "Involuntary", or smooth, muscles are found in the walls of all the hollow organs and tubes of the body (for example, blood vessels and intestines). There react slowly to stimuli from the autonomic nervous system. The "voluntary," or striated, muscles of the body attach mostly to the bones to move the skeleton, and under the microscope their fibers have a cross striped appearance. Striated muscle is capable of fast contractions. The heart wall is made up of special muscle fibers (cardiac muscle),
