1) The larynx is a hollow airway organ, the basis of which is cartilage; the largest of them is the thyroid. From the larynx, air enters the trachea.
2) The functions of the larynx: respiratory (air conduction), sound formation (oscillation of the vocal cords), prevents food from entering the respiratory system (this is ensured by the moving cartilage – the epiglottis – it reflexively closes the entrance to the larynx when food is swallowed).
3) The larynx changes with age. Its growth and function are associated with the development of the sex glands. The size of the larynx in boys during puberty increases. The voice changes (mutates).
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
