Essay about Describing the Human Respiratory System

The respiratory system consists of the nose, pharynx, larynx, bronchi and lungs. Their function is to filter warm and moistened air and conduct it into the lungs. The respiratory system contributes to homeostasis (highly complex interactions to maintain balance.)( Wiki) by providing for the exchange of gases, - oxygen and carbon dioxide, - between the atmospheric air, blood and tissue cells.

The respiratory system consists of the nose, mouth, pharynx, larynx, trachea, bronchi and lungs. These provide a passageway to allow air in and out of the body. Every cell in the body requires oxygen to survive.

C. Which structures found in the terminal bronchioles and alveoli normally would protect Cari’s lungs from infectious pathogens and particulate matter?

Factors that contribute to homeostasis of the system occur throughout the entire day and night, without conscious thought. The respiratory system functions for life-sustaining activities and if the respiratory system’s tasks are interrupted for any reason for more than a couple of minutes, the body can seriously be damaged irreversibly. Damage to tissues can occur, followed by the failure of all body systems, and eventually leading to death. While the inhalation of oxygen and removal of carbon dioxide are the primary functions of the respiratory system, it has other important roles in the body. The respiratory system helps regulate the balance of acid and base in tissues, a process necessary for the normal functioning of cells within the respiratory system. It also helps protects the body against pathogens and against toxic substances drifting in the air when inhaled. The respiratory system also houses the cells that detect smell through chemoreceptors, and assists in the production of sounds. The respiratory and circulatory systems work with one another to deliver oxygen to cells and remove carbon dioxide in a bi-phase process called respiration otherwise known as breathing. The first phase of respiration begins with inspiration or inhalation. Inhalation brings

The nasal septum divides the medially into the right and left portion. The nasal septum separates the cranial cavity by the cribriform plate of the ethmoid bone and by the oral cavity by the hand palate. Passageways called the superior, middle and inferior meatuses are the nasal conchae or turbinate bone that curl out from the lateral walls of the nasal cavity on each side. Nasal conchae support the mucous membranes that line the nasal cavity that help increase the surface area. The upper posterior portion of the nasal cavity is slit like and lines and contains the factory receptors that give use the sense of smell. The rest of the cavity conducts air to and from the nasopharynx.

The organs that make up the respiratory system are; nose and nasal cavity, mouth, pharynx, larynx, trachea, bronchi, bronchioles, alveoli, diaphragm and lungs.

The Respiratory Systems function is to supply the body with oxygen and excrete carbon dioxide .The respiratory system has many different parts, these include the nasal cavity, epiglottis, larynx, trachea, bronchi, lungs, bronchioles, alveoli, ribs, intercostal muscle and diaphragm. Nasal cavity The nasal cavity is where the oxygen enters the respiratory system and where carbon dioxide is released from the body.

It is also often referred to as the "windpipe." The trachea then branches off like a tree. The first splits of this "tree" are the bronchi, and the smallest branches are called the bronchioles. Thus after air travels through the trachea, it then reaches the bronchi, and spreads throughout the bronchioles.

passages. The nasopharynx serves as a passageway for air from the nose to the throat, and

Each single alveoli is wrapped with capillaries. Because of this, both the alveoli and capillaries are made up of a simple epithelium, which is a very thin tissue. This single layer of thin cells creates a short distance for gases to diffuse through. The oxygen will then be able to move through the thin capillary walls and into the cells while the carbon dioxide passes through the thin capillary walls from the cells. The short diffusions distance allows for a rapid gas exchange. This rapid and efficient gas exchange is required so that the cells can get the energy that they need for

The pharynx is an organ found in vertebrates and invertebrates. In humans the pharynx is part of the digestive system and also of the conducting zone of the respiratory system. The conducting zone also includes the nose, larynx, trachea, bronchi, and bronchioles, and their function is to filter, warm, and moisten air and conduct it into the lungs. It makes up the part of the throat situated behind the nasal cavity, and behind the mouth and superior to the esophagus and

The lower respiratory system contains the lower trachea, bronchi, bronchioles and alveoli in the lungs. The bronchi form as the lower part of the trachea and branch into two in the left and right lung. The upper segments of the bronchi have C shaped cartilage rings which keep the bronchi open for airflow. The bronchi divide into smaller bronchioles inside the lungs. They are made up of smooth muscle (without cartilage). The bronchioles continue to divide into alveoli; small grape shaped air sacs. Each alveoli is surrounded by pulmonary capillaries. The function of the alveoli is to perform the exchange of oxygen and carbon dioxide. There are millions of alveoli in the lungs, they have thin walls so the diffusion of oxygen and carbon dioxide can move across the membrane without resistance to the pulmonary capillaries.

Within the alveoli, the oxygen is transferred to the blood whilst simultaneously collecting waste carbon dioxide for excretion as we breath out. This transference is known as diffusion and is linked to the cardiovascular system.

Air enters your lungs through a system of pipes called the bronchi. These pipes start from the bottom of the trachea as the left and right bronchi and branch many times throughout the lungs, until they eventually form little thin-walled air sacs or bubbles, known as the alveoli. The alveoli are where the important work of gas exchange takes place between the air and your blood. Covering each alveolus is a whole network of little blood vessel called capillaries, which are very small branches of the pulmonary arteries. It is important that the air in the alveoli and the blood in the capillaries are very close together, so that oxygen and carbon dioxide can move (or diffuse) between them. So, when you breathe in, air comes down the trachea and through the bronchi into
