Human Anatomy

Anatomy is the science that studies the structure of the human body. Study the structure of each organ and the relationship between anatomy and the function of that organ.

Anatomy of the aorta

The descending aorta is the continuum from the aorta to the division, the diameter is less than the first two segments, the descending aorta is divided into two small parts, the thoracic aorta and the abdominal aorta.

Pharyngeal surgery

The pharynx is located behind the larynx, from the upper margin of the cervical cartilage to the lower margin of the ring cartilage, from the fourth to the lower margin of the sixth cervical vertebra, respectively.

Circulatory system: anatomical and functional

The circulatory system works by continuous pressure from the heart and valves, which ensures that the veins carry blood to the heart and the arteries that carry it out.

Visual organ anatomy

The orbit is a deep bony socket, containing the eyeballs, muscles, nerves, blood vessels, fat and most of the tears, with a pyramidal shape, foreground.

Anatomy of the endocrine glands

The endocrine gland can be a separate organ, it can also be clusters of cells concentrated in another organ, for example pancreatic islets in the pancreas or plaques in the testes.

Vestibular surgery

The ear canal is shaped like a two-sided concave lens, narrow upper and lower, lying along the vertical plane but slightly inclined so that the outer wall looks outwards and downwards.

Atlas of anatomy of the paranasal sinuses

The paranasal sinuses are divided into four groups; the sinuses, frontal sinuses, sinuses, these sinuses are often infected with bacteria that spread from the nasal passages and cause sinusitis.

The human body: organ systems

Organ system groups work together to create complete functions, there are 11 major organ systems in the body.

Heart: anatomy and function

The heart has a dual pump that transports blood away from it and back, and newly oxidized blood leaves the heart's side through the aorta.

Female reproductive system: anatomy and function

Women are born with a large number of oocytes, and until after the onset of puberty these cells are mature enough to sustain life.

Respiratory system: anatomical and functional

In addition to air distribution and gas exchange, the respiratory system filters, warms and moistens the breathed air, and the respiratory system also plays a role in speech.

The muscular system: anatomy and function

Engine movement occurs when nerve signals induce electrical changes in muscle cells, calcium is released into the cells and results in short muscle twitching.

Nervous system: anatomy and function

The nervous systems process the collected information and then send instructions to the rest of the body, facilitating an appropriate response.

Lungs: anatomy and function

The lungs are surrounded by the sternum and thoracic bone on the front and the vertebrae on the back, which protects the lungs and other organs in the chest.

Brain: anatomy and function

The brain is one of the most important body organs, so it's important to know how to recognize signs of potential problems.

Nose: anatomical and functional

As the air passes through the nose, specialized cells of the olfactory system, the brain recognize and identify odours, the hairs in the nose clear the air of foreign particles.
