The respiratory system is made up of the nose, pharynx, larynx, vocal cords, trachea, bifurcation of trachea, the main bronchi, the bronchioles and the alveoli of the lungs. Although air can enter the body through either the mouth or nose, it is the nose that is designed for this process.The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants.

The processes of inspiration and expiration are vital for providing oxygen to tissues and removing carbon dioxide from the body. Inspiration occurs via contraction of muscles such as the diaphragm, whereas expiration tends to be passive.Autoplay When autoplay is enabled, a suggested video will automatically play next.

The respiratory system is a vital system for life. Its job is to bring oxygen into the body, remove carbon dioxide from the body and to do this safely with minimal risk of infection, toxin absorption or blockage. We often divide the respiratory system into two sections – the upper respiratory tract and the lower respiratory tract. The upper respiratory tract ends and the lower respiratory.Go inside the human body and see first-hand how the respiratory system works. Vivid animation and real-life examples demonstrate the respiration process, including the transfer of oxygen.
Respiratory system lesson for kids. The lesson shows animation of ventilation and respiration. It covers the journey of air into the lungs, and the transfer of oxygen from the alveoli sacs to the red blood cells in the capillaries.Other components of the respiratory system conduct air to the lungs, such as the trachea (windpipe) which branches into smaller structures called bronchi. The process of breathing (respiration) is divided into two distinct phases, inspiration (inhalation) and expiration (exhalation).
