Explain The Structure Of The Respiratory System

➢ Inhaled air enters the nasal cavity, where it is cleaned, warmed and humidified on its way through the pharynx.

The Respiratory system is an integrated system of organs involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. Your Respiratory system is made up of the organs in your body that help you breathe. The Respiratory system is the system of the body that deals with breathing. The trachea is a wind pipe. The trachea is a pipe shaped by rings of cartillage. A Bronchi are two tubes that carry air into the lungs. The Respiratory system consistes of many different organs. The organs are the lungs, trachea, bronchi, alveoli, diaphragm, nose, mouth, and pharynx. In the Respiratory system the right lung is larger and has more lobes that the left lung becuase the heart is normally located on the left side, and takes up space where the lung would had been. The functions of the Respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The Respiratory system is also used for the of exchange gases. The importance of the Respiratory system is that it allows for the exchange of gases; meaning carbon dioxide and oxygen. These gas exchanges occur in the alveoli's and the capillaries. This gas exchange of gases is the Respiratory system's means of getting oxygen to the blood. The goal of breathing is to

The main Function of the respitory system is gaseous exchange. This refers to the process of oxygen and carbon dioxide moving between the lungs and blood. Gaseous exchange in the lungs refers to the movement of oxygen into the body, and the removal of carbon dioxide from the body. It takes place in the lungs, especially in the alveoli surface through diffusion.

Consist of the nasal passage, pharynx, esophagus, larynx, trachea, lungs, diaphragm, bronchi, and pulmonary artery and vein.

Also known as the oral cavity. Another opening of the respiratory system and can also take air in and out

Air (oxygen) is inhaled into the body by the nose. The air is warmed filtered and moistured in the nasal cavity as the air needs to be cleaned before passing it along to the pharynx. Mucous is held in the sinus cavity. With the joint help from the mucous and the tiny hairs in the nose our nose ensures that the air is cleared of pathogens so that the air is clean to move on to the pharynx. The tiny hairs in the nose causes us to sneeze resulting in pathogens that may have been inhaled to be sneezed out and released back into the atmosphere.

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.

Nasal Cavity- its a space within the nose and the skull with the mucus membrane which warms and moisturizes the air you breathe In that’s going in the body by passing through the nostrils before it passes into the nasopharynx, The human nose is divided into two parts the external nose and the internal nasal cavity. There are hair with the cavity that filters out dust, pollen and other foreign particles. Before the air passes into the two passages the nasal cavity.

The blood that travels to the tissues and organs in the body have a high level of oxygen. Diffusion occurs between the capillaries and the body’s tissues and organs. Oxygen diffuses from the blood into the body’s cells and tissues, whereas carbon dioxide is diffused from the body’s tissues and organs into the blood where it then travels to the lungs. Here, it diffuses across the thin walls of the alveoli, where it is removed out of the body by exhalation.

Air can be breathed in through both the nose and the naval cavity, or the mouth, also known as the oral cavity. The air, regardless of the path taken, will always lead to the pharynx, a space located at the back of throat. It will progress through the larynx,

• Once air pass through the pharynx, and enters the larynx, the two pairs of ligaments cover by mucosa called the vestibular folds, and prevents foreign particles from entering the lower respiratory system.

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.

The bronchioles, I believe to be the most complex part of the respiratory system. The bronchioles really do have an important role in the respiratory system. After the bronchi ends bronchioles begin. The bronchioles conduct air form the bronchi, pass air through the nose, mouth and then to the alveoli. The bronchioles function by distributing air through the lungs by constricting and dilating, this control the amount of air that goes through the lungs. The bronchioles began to taper off unto three tiny air passageways: the lobular bronchioles, terminal, and respiratory bronchioles. The bronchioles have no support by cartilage, and because of this they are more likely to be affected by conditions that may cause obstruction of the airway. The
