Respiratory system (respiratory system).The respiratory system is the system that contains the organ associated with breathing. Is the air in and out of the body, resulting in the oxygen react with nutrients, energy, water, and carbon dioxide gas oxide. The breathing process happened to all the cells constantly breathing need to rely on 2 structure types are the diaphragm muscles and the ribs.Mechanism of respiratory system.1. Inhale (Inspiration) diaphragm to move down, the ribs will move higher. The volume of stock increased air pressure in the area around the lungs lower than the outside air. The outside air is moving into the nose, trachea, and to the alveolar lung.2. Exhale (Expiration) diaphragm to move high rib will slide down. The volume of out less air pressure in the area around the lungs than the outside air. Air in the alveoli and alveolar lung moves from lung to the trachea and out through the nose.The vital organs of the respiratory system.1. The nose (Nose) is the way of the air defense first. Consists of a triangular structure of bone and cartilage The outer skin is covered with skin. The inner surface is lined with mucous membranes (Mucous membrane) is the opening of the nose is 2 channels separated by walls กั้ (Septum) within the mucosa have oil glands act as barrier to prevent dust from going into the lungs. Nasal in the deep split into 2 parts. The upper area is about the smell. The lower part is a passage of air. The part of the ethmoid bone (Ethmoid) and Navy นคี lower (Inferior conchae) sticking out 3, to allow the air to pass through a lot. And between the bones sticking out, a groove red meat (Metus), which is the way of the air, and there are on each side 3. Grooves in red meat is the opening of a sinus (Air sinus) in the skull, which is 4 of together the sinus (Maxilla cheekbones. Sinus) on the forehead (Forntal sinus) bridge (Ethmoid sinus) and bone สฟ eat alkaloids (Sphenoid sinus) nose than a way through the air into the lungs. Also served to smell, make clear sound of moist air and the dust filter are also water eyes.
