1 mar 2019 · However, significant pulmonary limitations to exercise performance and oxygen delivery may occur during high-intensity exercise. This chapter focuses on the structure and function of the healthy human respiratory system and how the increased ventilatory requirements of exercise are met.

7 cze 2024 · The upper respiratory tract consists of the nose and the pharynx. Its primary function is to receive the air from the external environment and filter, warm, and humidify it before it reaches the delicate lungs where gas exchange will occur.
The organs of the respiratory system form a continuous system of passages called the respiratory tract, through which air flows into and out of the body. The respiratory tract has two major divisions: the upper respiratory tract and the lower respiratory tract.

The upper respiratory tract refers to the parts of the respiratory system that lie outside the thorax, more specifically above the cricoid cartilage and vocal cords. It includes the nasal cavity, paranasal sinuses, pharynx and the superior portion of the larynx.
The main function of the lungs is to perform the exchange of oxygen and carbon dioxide with air from the atmosphere. To this end, the lungs exchange respiratory gases across a very large epithelial surface area—about 70 square meters—that is highly permeable to gases.
11 sie 2023 · This section will explain the anatomy and the physiology of the respiratory system, acute and chronic adaptations to exercise training, factors affecting the adaptation, possible complications that may occur during or after exercise for respiratory system pathologies, and ways to deal with them.
