Nervous system

Peripheral nerves: structure, classification and functions

43 pairs of nerves connect the central nervous system to every corner of the body. Cranial, spinal, vegetative - we analyze all types.

Urinary system

Kidneys: structure, nephrons and blood filtration

Two bean-shaped organs filter 180 liters of blood per day. A million nephrons in each kidney - let's disassemble the device.

Respiratory system

Respiratory muscles: mechanism of inhalation and exhalation

The diaphragm, intercostal muscles and accessory muscles - how they work together to provide ventilation to the lungs.

Respiratory system

Lungs: anatomy, lobes, bronchial tree and gas exchange

The gas exchange area is 70 m², 300 million alveoli and 15,000 breaths per day. We disassemble the structure of the main respiratory organ.

Trachea and bronchi: airways from the larynx to the alveoli

Cartilaginous rings, ciliated epithelium and bifurcation - how the airways are structured and why they are so important.
