This is known as internal or tissue respiration. The human respiratory system consists of a pair of lungs and a series of air passages leading to the lungs. Oxygen and carbon dioxide must be transported to and from the lungs and tissue cells of the body via the bloodstream. The respiratory system, which includes air passages, pulmonary vessels, the lungs, and breathing muscles, aids the body in the exchange of gases between the air … The regions of the pharynx are nasopharynx, oropharynx, and laryngopharynx. Human respiratory system - Human respiratory system - The mechanics of breathing: Air moves in and out of the lungs in response to differences in pressure. Here is how lungs work as the center of your breathing, the path a full breath takes in your body, and a 3-D model of lung anatomy. Similarly, contraction of the external intercostal muscles moves the ribs upwards and outwards. ADVERTISEMENTS: Human Respiratory System and it’s Mechanism! The exchange of oxygen of the air for the carbon dioxide of the blood takes place in the respiratory organs and is known as external respiration. The lungs are the main part of your respiratory system. Respiratory gas transport. Gas exchange between the pulmonary blood and alveoli must take place. The true respiration, resulting in the release of energy, occurs in the tissues by the exchange of oxygen of blood for the carbon dioxide of the tissues. The oropharynx consists of stratified squamous epithelium and the laryngopharynx consists of respiratory pseudostratified. Pleura, plural pleurae, or pleuras, membrane lining the thoracic cavity (parietal pleura) and covering the lungs (visceral pleura). Internal respiration. Epithelial tissue: This tissue covers the surface of the body and lines the internal organs. The entire respiratory tract (passage) consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. The diaphragm is a dome-shaped muscle that curves upwards towards the lungs. PHARYNX is made up of the fibromuscular tube that consists of a ring of specialized lymphatic tissue. Muscles of the Respiratory System. There are two other types of animal tissue—muscular and nervous. Its main function is protection. ; Nasal chamber – which is lined with hair and mucus to filter the air and remove dust and dirt. Air enters the nose through the nostrils. Animal tissues: The cheek cells are a type of epithelial tissue, while blood is a kind of connective tissue. When air passes through the nose, […] For Cellular respiration C6H12O6+6O2 ---> (many enzymes many steps)---> 6CO2+6H2O+energy(used to make ATP) + heat Why do we need to get rid of the CO2 gas made by cellular respiration? The respiratory tract in humans is made up of the following parts: External nostrils – For the intake of air. Respiratory System Diagram. When it contracts, it becomes flattened and therefore increases the volume of the thoracic cavity. The parietal pleura folds back on itself at the root of the lung to become the visceral pleura. External respiration. ; Pharynx – It is a passage behind the nasal chamber and serves as the common passageway for both air and food. In health the two pleurae are in contact.
