Digestion Organ

The apparatus of the Digestion of the Food consists of the alimentary canal and of certain accessory organs.

The alimentary canal is a musculo membranous tube, about thirty feet in length excluding from the mouth to the anus, and lined throughout its entire extent by mucous membrane. It has received different names in the various parts of its course: at its commencement, the mouth, we find provision made of the mechanical division of the food (insalivations), and for its admixture with a fluid secreted by the salivary glands (insalivations); beyond this are the organs of deglutition, the pharynx and the esophagus, which convey the food into that part of the alimentary canal (the atomach) in which the principal chemical changes occur, and in which the reduction and solution of the food take place; in the small intestines the nutritive principles of the food (the chyle) are separated, by its admixture with the bile, pancreatic and intestinal fluids, from that portion which passes into the large intestine, most of which is expelled from the system.

The digestion parts are divided into:
Alimentary Canal:
  • Mouth
  • Pharynx
  • Esophagus
  • Stomach

Intestine itself divided into two main parts:
Small intestine:
  • Duodenum
  • Jejunum
  • Ileum
  • Caenum
  • Rectum
Accessory Organs:
Teeth
Salivary glands:
  • Parotid
  • Submaxillary
  • Sublingual

Human Organs

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

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),
