Anatomy of the Respiratory System & Related Systems 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.natomy 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).

What is the purpose of lobes in the lungs? Each lung is anatomically divided into lobes, each with a large ‘lobar’ airway, or bronchus. Each lobar airway divides, into individual segments within each lung. The right lung has 3 lobes: upper, lower and middle lobes; the left lung has 2 lobes: upper and lower. The right lung has 10 segments, the left lung 8 segments. On a microscopic level, each bronchus divides through several generations until it ends in a cluster of small air sacs, called alveoli.

Human Body - Medical English The navel, more commonly referred to as the belly button, is located here as well. On the inside of the upper body are the heart for pumping blood and the lungs for breathing. The rear side of the upper body is called the back, inside which the spine connects the upper body to the lower body. Upper Limbs (arms)

Picture of the Lungs 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 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.

Chapter-14 The Respiratory System-1 What is the serous membrane covering the lungs?     Lung coverage     The serous membrane that covers the lungs is called the Pleural Membrane. The lung is covered by a serous membrane called what? Pleural Cavity is the body cavity that surrounds the right and left lung. The pleura is a serous membrane which folds back to form a two-layered, membrane structure. The thin …space between the two pleural layers is known as the pleural cavity; it normally contains a small amount of pleural fluid. The outer pleura parietal pleura is attached to the chest wall.

The upper lobe on the right is further subdivided by the horizontal fissure into definitive upper lobe - above the fissure - and middle lobe - below the fissure. The fissures extend from the surface of the lung to its hilum. Along this route, visceral pleura apposes visceral pleura.

Superior vena cava Superior vena cava The lung consists of five lobes. The left lung has a superior and inferior lobe, while the right lung has superior, middle, and inferior lobes. Thin walls of tissue called fissures separate the different lobes. The superior lobes of each lung are the uppermost pieces, also called the upper lobes.

Respiratory tract Details of upper respiratory tract. The upper respiratory tract, can refer to the parts of the respiratory system lying above the sternal angle (outside of the thorax), above the vocal folds, or above the cricoid cartilage. The larynx is sometimes included in both the upper and lower airways.

Lung Cancer The right lung has three lobes, while the left lung is divided into two lobes and a small structure called the lingula that is the equivalent of the middle lobe on the right. The major airways entering the lungs are the bronchi, which arise from the trachea, which is outside the lungs.

Respiratory tract These bronchioles give rise to the air sacs in the lungs called the alveoli. The lungs are the largest organs in the lower respiratory tract. The lungs are suspended within the pleural cavity of the thorax. The pleurae are two thin membranes, one cell layer thick, which surrounds the lungs.he lower respiratory tract or lower airway is derived from the developing foregut and consists of the trachea, bronchi (primary, secondary and tertiary), bronchioles (including terminal and respiratory), and lungs (including alveoli.

Lungs The base of the lungs is concave to follow the contour of the diaphragm. The left lung is slightly smaller than the right lung because 2/3 of the heart is located on the left side of the body. The left lung contains the cardiac notch, an indentation in the lung that surrounds the apex of the heart. Each lung consists of several distinct lobes. The right lung (the larger of the two) has 3 lobes – the superior, middle, and inferior lobes. The horizontal fissure separates the superior lobe from the middle lobe, while the right oblique fissure separates the middle and inferior lobes.

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.

Your Largest Organ isâ¦ The top layer, which is visible on the outside of your body, is called the epidermis. The very top of this layer is actually dead cells, which are continually being replenished from below as younger living cells push the older cells upward. This cycle repeats about one thousand times during your life.

This comes from the Latin word for an open entrance area in a house, because the atria are where the blood enters the heart after returning from either the body or the lungs.

- The organs of the chest are protected by the ribs. The area between the lungs in the middle of the chest is called the mediastinum. It contains the heart, windpipe (trachea), food pipe (esophagus), blood vessels, and many lymph nodes.igure 1: The Respiratory System* Air moves in and out of the body by the action of muscles. The diaphragm is a large muscle that sits below the lungs. It separates the lungs and other organs in the chest from the organs of the abdomen.
