The lungs are the center of the respiratory (breathing) system. Every cell of the body needs oxygen to stay alive and healthy. Your body also needs to get rid of carbon dioxide. This gas is a. Lung Structure The lungs are roughly cone shaped, with an apex, base, three surfaces and three borders. The left lung is slightly smaller than the right - this is due to the presence of the heart. Each lung consists of: Apex - The blunt superior end of the lung. It projects upwards, above the level of the 1st rib and into the floor of the neck.

Lungs Diagram in Human Body Humans have a right and a left lung positioned in the chest cavity. Jointly, the lungs inhabit most of the intrathoracic space. Lungs are responsible for adding oxygen and removing carbon dioxide from the blood, thus serving as a gas-exchanging structure for respiration. Overview A step-by-step explanation of how your lungs work. What are your lungs? Your lungs make up a large part of your respiratory system, which is the network of organs and tissues that allow you to breathe. You have two lungs, one on each side of your chest, which is also called the thorax. Lungs are a pair of respiratory organs situated in a thoracic cavity. Right and left lung are separated by the mediastinum. Texture -- Spongy Color - Young - brown Adults -- mottled black due to deposition of carbon particles Weight- Right lung - 600 gms Left lung - 550 gms THORACIC CAVITY SHAPE - Conical Apex (apex pulmonis) Base The human lungs are a pair of spongy organs within the thoracic cavity that facilitate gaseous exchange. They are a part of the respiratory system, which also includes the nose, nasal sinuses, mouth, pharynx, larynx, and trachea. At the level of the lungs, much-needed oxygen is absorbed into the blood, while waste gases are excreted and exhaled.

The diaphragm is the flat, dome-shaped muscle located at the base of the lungs and thoracic cavity. The lungs are enclosed by the pleurae, which are attached to the mediastinum. The right lung is shorter and wider than the left lung, and the left lung occupies a smaller volume than the right. The purpose of the lung is to provide oxygen to the blood. The respiratory system divides into airways and lung parenchyma. The airways consist of the bronchus, which bifurcates off the trachea and divides into bronchioles and then further into alveoli. The parenchyma is responsible for gas exchange and includes the alveoli, alveolar ducts, and bronchioles. Lungs have a spongy texture and have.

Given below is a labeled diagram of the human lungs followed by a brief account of the different parts of the lungs and their functions. Each lung is enclosed inside a sac called pleura, which is a double-membrane structure formed by a smooth membrane called serous membrane. The respiratory system, also called the pulmonary system, consists of several organs that function as a whole to oxygenate the body through the process of respiration (breathing).

The breathing cycle is controlled by the respiratory centre located inside the medulla oblongata and the pons of the brain stem. Three major collections. Respiratory system diagram The respiratory system How we breathe Respiratory conditions Summary The respiratory system allows air to reach the lungs, from which oxygen enters the blood.
