The Lungs and Respiration The body contains two lungs, of which one is positioned on the left side of the chest cavity and the other on the right side. The right lung is separated into three divisions or lobes, while the left lung contains two lobes. Each lung is surrounded by a two-layered membrane lining (pleura) that attaches the lungs to the chest cavity. The membrane layers of the pleura are separated by a space filled with fluid. 02

Anatomy of the Respiratory System & Related Systems The lungs are the body's major organs of respiration. The two vital parts that make up the lungs are located on each side of the chest within the rib cage. They are separated by the heart and other contents of the mediastinumthe tissues and organs of the middle chest (e.g., the heart and large vessels, windpipe).xygen-poor blood is brought back to the lungs by the pulmonary artery. The pulmonary artery divides into branches that parallel the bronchial tubes and ends in a network of pulmonary capillaries (tiny blood vessels) within the walls of the small air passages and alveoli of the lungs.

Bronchus A bronchus, is a passage of airway in the respiratory tract that conducts air into the lungs. The first bronchi to branch from the trachea are the right main bronchus and the left main bronchus. These are the widest and enter the lungs at each hilum, where they branch into narrower secondary bronchi known as lobar bronchi, and these branch into narrower tertiary bronchi known as segmental bronchi. Further divisions of the segmental bronchi are known as 4th order, 5th order, and 6th order segment

Lung The Right and Left Lung. Human lungs are divided into right and left lungs, and further subdivided into lobes. The right and left lung are not symmetrical, since your right lung has three lobes and your left lung has two. The lobes on both sides of your lungs are separated by fissures. The oblique fissure separates the largest lobe, the left upper lobe, or superior lobe, from the one below it.

- The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.

- An entire lobe of the lung is usually removed when treating a relatively small lung cancer. The entire lobe is removed in order to remove not only the cancer itself, but also the surrounding lymph nodes. Lymph nodes are the body’s filters, a line of defense, against the spread of the lung cancer.The lymph nodes will trap cancer cells that are attempting to spread from the cancer through the lymphatic system.he entire lobe is removed in order to remove not only the cancer itself, but also the surrounding lymph nodes.

Lung The lungs are the primary organs of respiration in humans and many other animals. Humans have two lungs, a right lung and a left lung. They are situated within the thoracic cavity of the chest. The right lung is bigger than the left lung, as the left lung shares space in the chest with the heart. The lungs together weigh approximately 1.3 kilograms (2.9 lb), with the right lung weighing more than the left.

Anatomy of the Respiratory System & Related Systems Anatomy of the Respiratory System. The lungs are the body's major organs of breathing (respiration). The lungs are located on each side of the chest within the rib cage. They are separated by the heart and other contents of the mediastinum—the tissues and organs of the middle chest (e.g., large blood vessels, windpipe). The lungs are shaped like an upside-down butterfly. The top of each lung (called the apex) extends into the lowest part of the neck, just above the level of the first rib. The bottom, or base, of each lung extends down to the diaphragm, which is the major breathing-associated muscle that separates the chest from the abdominal cavity.

What are the major organs and tissues of the respiratory system, and what do they do Bronchi (singular: bronchus) Each bronchus leads to one of the lungs. Bronchi are air passage ways in the lungs. Within each lung, the large bronchi subdivides into smaller bronchi, which lead to even smaller air passageways called bronchioles. These continue to subdivide until they reach a series of dead ends were there are millions of tiny air sacs called alveoli.

Where are the lungs located? The lungs are covered by a thin tissue layer called the pleura. The same kind of thin tissue lines the inside of the chest cavity -- also called pleura. A thin layer of fluid acts as a lubricant allowing the lungs to slip smoothly as they expand and contract with each breath.he trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic. The bronchioles eventually end in clusters of microscopic air sacs called alveoli.

- This is the conducting system of passages or airways that lead from the environment to the exchange surface of the lungs. Divided into the upper and lower tract. The upper tract is the nasal cavity, pharynx and larynx. The lower respiratory tract is the trachea, two bronchi, their branches and the lungs. This is also called the thoracic portion because it is in the thorax. The thorax/chest cavity is bound by bones of the spine and rib cage with their appropriate muscles.

Lung Scan If both scans are done, the test is called a V/Q scan. The ventilation scan usually is done first. A lung scan is done to: 1  Find a blood clot that is preventing normal blood flow (perfusion) to part of a lung (pulmonary embolism).  Check the flow of blood (perfusion) or air (ventilation) through the lungs.

Where Are the Lungs Located in the Human Body? The left lung is slightly smaller than the right lung because the right lung contains three sections called lobes, whereas the left lung only has two lobes. The left lung must be smaller to accommodate the heart's position. Surrounding the lungs is the rib cage, which protects the lungs from damage.

- Lung cancer is the rapid growth of abnormal cells in the lung tissue. Surgery to remove all or part of a lung may be done by making a cut on one side of your chest (thorax) during a procedure called a thoracotomy. Surgery that uses this approach avoids areas in the chest that contain the heart and the spinal cord.

- The types of lung surgery are: Wedge resection (segmentectomy). The surgeon removes a small wedge-shaped piece of lung that contains the lung cancer and a margin of healthy tissue around the cancer. This is likely to be done when your lung function would be decreased too much by removing a lobe of lung (lobectomy).

Lung The cone-shaped lungs are sponge-like organs that fill the chest cavity and make up most of the lower respiratory tract. Their most important job is providing oxygen to capillaries so they can oxygenate blood. Each lung is divided into lobes. The right lung has three, but the left lung has only two, thus allowing room to accommodate the heart. Together, the lungs’ tissue surface is almost 40 times greater than the body’s outer surface, making the lungs (together) one of the largest organs in the body.

Where are the lungs found? From front to back the lungs fill the rib cage but are separated by the heart, which lies in between them. The lungs are divided into different parts which are called lobes. The right lung has three lobes called upper, middle and lower lobes. The left lung only has two lobes, the upper and lower.

Parts of the Respiratory System and their Function Trachea: The trachea is also known as windpipe. The trachea filters the air we inhale and branches into the bronchi. Bronchi: The bronchi are the two air tubes that branch off of from the trachea and carry atmospheric air directly into the lungs.Lungs: The main organ of the respiratory system is lungs. Lungs are the site in body where oxygen is taken into and carbon dioxide is expelled out.rachea: The trachea is also known as windpipe.

- But the inside contains the real lowdown on the lungs! At the bottom of the trachea (say: TRAY-kee-uh), or windpipe, there are two large tubes. These tubes are called the main stem bronchi (say: BRONG-kye), and one heads left into the left lung, while the other heads right into the right lung.
