What are the lungs made of? The lungs are composed of various specialized cells and tissues -- not just simple tubes or pipes. Lining them are epithelial cells with specialized hairs, or cilia, which help trap particles and prevent infection from reaching the lungs.

- The larynx (lar-inks), commonly called the voice box, is a tube shaped structure comprised of a complex system of muscle, cartilage, and connective tissue.oice production begins with respiration (breathing). Air is inhaled as the diaphragm (the large, horizontal muscle below the lungs) lowers. The volume of the lungs expands and air rushes in to fill this space. We exhale as the muscles of the rib cage lower and the diaphragm raises, essentially squeezing the air out.

- Unlike the heart, the lungs have no muscle tissue. Instead, muscles in the rib cage and the diaphragm do all the work of lifting the ribs upward and outward to let the air in, and then relaxing to force the air out.nlike the heart, the lungs have no muscle tissue.

Where are the lungs located? Carbon dioxide, a waste product of metabolism, travels from the blood to the alveoli, where it can be exhaled. Between the alveoli is a thin layer of cells called the interstitium, which contains blood vessels and cells that help support the alveoli. The lungs are covered by a thin tissue layer called the pleura.

The Lungs 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.he main function of the lungs is to perform the exchange of oxygen and carbon dioxide with air from the atmosphere. To this end, the lungs exchange respiratory gases across a very large epithelial surface area—about 70 square meters—that is highly permeable to gases.

The Respiratory System A lung is an individual organ composed of tubular structures and alveoli bound together by fibrous connective tissue (FCT). In the human, there are two lungs--right and left. Each lung is supplied by a primary or mainstem bronchus leading off of the trachea. The right lung is larger in volume than the left lung.

Lung The lungs are located in the chest on either side of the heart in the rib cage. They stretch from close to the backbone in the rib cage, and rest on the diaphragm. The left lung shares space with the heart, with an angular notch in its anterior border called the cardiac notch.hey 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.

- The pleura (the covering of the lungs). There are 2 fibrous sheets of tissue that cover the lungs and help to protect them. These are callled the pleura or pleural membranes. Doctors usually call these the lining of the lungs, although this can be a bit confusing as they are on the outside.The gap between the pleura is called the pleural space.lose to the lungs and airways are lymph nodes (also called lymph glands). They are small bean shaped glands found throughout the body. They are connected by a network of tubes called lymphatics or lymphatic vessels. This network carries a fluid that leaks out of the blood vessels and bathes the body tissues and cells.

- The lungs are a pair of organs located in the chest cavity that perform respiration. These are about 12 inches long. The lungs are a protective membrane. The area between the two lungs is called the mediastinum, which contains the heart, trachea, esophagus and blood vessels. The lung is protected by the ribcage.

Lung The lungs are part of the lower respiratory tract, and accommodate the bronchial airways when they branch from the trachea. The lungs include the bronchial airways that terminate in alveoli, the lung tissue in between, and veins, arteries, nerves and lymphatic vessels. The trachea and bronchi have plexuses of lymph capillaries in their mucosa and submucosa.

What Is Lungs Definition? Lungs are the major organ of our respiratory system, helping us obtain oxygen and get rid of carbon dioxide. Our chest cavity houses a pair of lungs which open to the external environment through the nose and mouth. A cylindrical tube, called trachea, is the main link between the lungs and the nose and mouth. When we breathe in, air travels through the trachea to our lungs. As the trachea moves down the chest, it splits into two branches called bronchus, one for each lung. Each bronchus then further subdivides into several smaller tubes called bronchioles.

Lungs Each soft, spongy lung is roughly cone-shaped with the superior end of the lung forming the point of the cone and the inferior end forming the base. The superior end of the lungs narrows to a rounded tip known as the apex. The inferior end of the lungs, known as the base, rests on the dome-shaped diaphragm.

Lung In humans, the lungs are located on either side of the heart in the chest, with the left lung sharing the left side of the space with the heart, which sits in an impression called the cardiac notch.n this image, lung tissue has been dissected away to reveal the bronchioles. The lung is the essential respiratory organ in many air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and most other vertebrates, two lungs are located near the backbone on either side of the heart.

Your Cigarettes May Be Killing You Filters are defective — and the companies know it. You may be inhaling filter fibers into your lungs. Most cigarette filters are made of the same mater ial as camera film (cellulose acetate). Each individual filter is made of thousands of tiny fibers. The inside of the filter is painted white to make it appear clean. During smoking, these fibers can come off into your mouth and be inhaled into your lungs.

Top 5 reasons kids play sports Surprise; “winning” didn’t even make the top ten reasons. Study after study comes up with the same #1 result. Kids play sports for the fun of it. And not having fun is one of the major reasons 70 percent of kids quit playing sports by the time they’re 13. Most often it’s parents and coaches who want to win. Kids hardly care. For them, winning is just icing on the cake.

Saphenous Nerve Block at the Knee Saphenous nerve block at the knee is useful in the evaluation and management of distal lower extremity pain thought to be subserved by the saphenous nerve. The technique is also useful to provide surgical anesthesia for the distal lower extremity when combined with tibial and common peroneal nerve block or lumbar plexus block.

Lung and other Breathing Problems The lung is an organ found in your chest cavity. Each lung is divided into lobes. On the left side, you have the left upper- and the left lower- lobe. On the right side, there are 3 lobes: the right upper-, mid-, and lower lobe. A thin lining, called the pleura, surrounds the lobes of the lung. As you breathe, air moves down your windpipe (your trachea), through a tree-like structure called the bronchi.

Electronvolt In physics, the electronvolt (symbol eV, also written electron-volt) is a unit of energy equal to approximately 1.6×10−19 joules (symbol J). By definition, it is the amount of energy gained (or lost) by the charge of a single electron moving across an electric potential difference of one volt. Thus it is 1 volt (1 joule per coulomb, 1 J/C) multiplied by the elementary charge (e, or 6981160217662079999♠1.6021766208(98)×10−19 C).

Lungs Bronchi. Air enters the body through the nose or mouth and passes through the pharynx, larynx, and trachea. Just before reaching the lungs, the trachea then splits into the left and right bronchi – large, hollow tubes made of hyaline cartilage and lined with ciliated pseudostratified epithelium.

Human respiratory system Locate Those Lungs. Your lungs are in your chest, and they are so large that they take up most of the space in there. You have two lungs, but they aren't the same size the way your eyes or nostrils are. Instead, the lung on the left side of your body is a bit smaller than the lung on the right. This extra space on the left leaves room for your heart. Your lungs are protected by your rib cage, which is made up of 12 sets of ribs.
