Kidney Structure

Human Kidney and Function of Kidney


Kidney is a human organ  like kidney beans shaped. In humans, kidney size, which is a length of 10 to 12 cm, width 5-6 cm, and thick, 3-4 cm, weighing about 140 grams. In cross kidneys, visible parts are different. The sections are from outside into the cortex, medulla, and pelvis. In the renal cortex and medulla there are about 1 million nephrons. Nephron is the structural and functional unit of the smallest of the kidney. Nephron serves as a screening tool.


Human Organ

Nephron is shaped like a large worm-headed eagle with a body like the winding. At the head there is a fine mesh that can only be bypassed by certain substances. Blood cells and blood proteins can not pass through this filter because it was bigger. The composition of the nephron consists of the following sections.

1) Malpighian Body, which includes Bowman's capsule and glomerulus.
2) convoluted tubules including proximal tubules, Henle, and distal tubules.

Some tubular-shaped winding, and some straight. The first section of the tubular winding, called the proximal tubule. After that there is a loop of Henle. Tubule weaved again as the second bend of the distal tubule called then concatenated with the tubule reservoir across the cortex and medulla. Each nephron consists of malpighi body. In this malpighi there is a section called Bowman's capsule-shaped bowl and in it there is glomerus. In the glomerular capillaries have blood.

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),...
