Describe The Main Functions Of The Trachea

Air is inhaled from the mouth and/or nose and goes through the trachea. The trachea is then split into the bronchial tubes. The bronchial tubes travel through the lungs and eventually split into tiny tubes called the bronchioles, at the end of a bronchiole, there is a sac called the alveoli. The alveoli is surrounded by blood vessels called the capillaries. The initially inhaled air passes through the alveoli walls and into the blood.

The primary function of the respiratory system is the exchange of gases. The respiratory system allows oxygen and carbon dioxide exchange, this is necessary to sustain life. During the process of breathing air is inhaled and carbon dioxide is exhaled, this change of gases occurs in the alveoli. The inhaled oxygen passes into the alveoli and then diffuses into arterial blood. The waste rich blood from the veins releases carbon dioxide into the alveoli which is

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

“Obtaining oxygen and removing carbon dioxide are the primary functions of the respiratory system, which includes tubes that filter incoming air and transport air into and out of the lungs as well as microscopic air sacs where gases are exchanged” (Moini, 2013, p.497). Our respiratory system is broken down into two sections known as the upper respiratory tract and the lower respiratory tract.

The nose has two nostrils that provide an opening through which air can enter and leave the nasal cavity. There are many hairs in the opening to help prevent the entry of large particles that are in the air.

The act of breathing starts from the mouth. You breathe in air through your mouth and nose, and it travels through the back of your throat and down your wind pipe or trachea. Your trachea the divides itself into air passages called bronchial tubes. For your Lungs to perform at their best these passages needed to be clear during inhaling and exhaling. And free from mucus swelling and inflammation.

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

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 main organs of the respiratory system are the lungs – they are the location where the gas exchange between oxygen and carbon dioxide takes place. The lungs therefore expand when you breathe in, and retract when you breathe out. This is done through the diaphragm – a sheet of muscle that is positioned under the lungs. As one inhales, their diaphragm contracts and moves itself downward, increasing the space for your lungs to expand to. The ribs also move to enlarge the possible area the lungs can expand to. This pressure causes air to be sucked through the body to the lungs. When one exhales, the opposite takes place – the diaphragm moves upwards and returns to normal, allowing the process to happen again.

As we breathe in, the muscles in the chest wall force the thoracic area, ribs and connective muscles to contract and expand the chest. The diaphragm is contracted and moves down as the area inside the chest increases as air enters the lungs. The lungs are forced open by this expansion and the pressure inside the lungs becomes enough that it pulls

The chest contains two lungs, one lung on the right side of the chest, the other on the left side of the chest. Each lung is made up of sections called lobes. The lungs are soft and protected by the ribcage. The purpose of the lungs is to bring oxygen into the body and to remove carbon dioxide. Oxygen is a gas that provides us with energy, while carbon dioxide is a waste product or “exhaust” of the body.

The respiratory system is divided in two different tracks, upper tract including nose, nasal cavity, sinuses, and pharynx; Lower respiratory tract includes larynx, trachea, bronchial tree, and lungs. The system served the main purpose of transporting air into the lungs, and flows from the top to bottom.

The air is travels through the bronchi as they subdivide becoming smaller and smaller (with the

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
