Respiratory system
The main structural components of the respiratory system consists of the nasal cavity and the pharynx then lower in the body there is the larynx, trachea and the lungs when you move lower into the body there is the bronchi and the bronchioles, then at the bottom of the body there is the alveoli and the diaphragm.
Nasal Cavity- Is a hollow space in the nose and skull that has lots of mucus on the membrane. The function of the nasal cavity is to warm, moisturise and filter the air entering the body, before it reaches the lungs.
Trachea- Is normally called the windpipe. The Pharynx and larynx are also located along the trachea. The main function of the trachea is the air to and from the lungs. The Trachea is located at the base of the neck and in the body’s middle line.
Lungs- Is to process gas exchange called respiration. Oxygen from the Trachea comes in and enters the blood and a waste of gas, which is the result of metabolism. The lungs also help us get rid of carbon dioxide as we breathe it out.
Alveoli- Gas Exchange occurs here.
Main the functional unit of the lungs
Site of gaseous exchange
Very thin walled – so that gas can pass quickly into and out of the blood
Huge blood supply – Highly vascular
Massive surface area
Oxygen passes from the lungs into the blood
Carbon dioxide passes from the blood into the lungs and out to the atmosphere when you breathe out
When we inhale there is a large muscle called the diaphragm. The diaphragm flexes downward to
Exhalation, (breathing out), is the opposite of inhalation and occurs when the inspiratory muscles relax causing the diaphragm to depress which decreases the lung volume. This decrease in volume causes the alveolar pressure to increase therefore the carbon dioxide in the lungs flows from a high pressure to a lower pressure in the atmosphere. (Tortora & Derrickson, 2011)
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
Gas exchange is when oxygen is delivered from the lungs to the blood stream and carbon dioxide is taken out of the bloodstream and into the lungs. Gas exchange occurs within the lungs between the alveoli and capillaries which are in the walls of the alveoli. The walls of the alveoli share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart. At the same time, the carbon dioxide in the alveoli are exhaled out of the body.
There is a small amount of carbon dioxide and more oxygen in the body because of gases exchange this is where oxygen form the lungs is transferred in to the blood and carried to the heart and when carbon dioxide is carried in to the lungs forms the blood and is exacted outwards by breathing. Mitochondria also need oxygen to create carbon dioxide for the body so the gas exchange can happen again. Outside the body there is a smaller amount of oxygen but it is still higher than CO2.
The respiratory system is made up of organs and tissues that help you breathe. The main parts of this system are the lungs, the trachea, the diaphragm, alveoli and nasal cavity. The respiratory system starts with the mouth and the nose, where air is brought in, then passes through the larynx and the trachea into the chest cavity. http://www.nhlbi.nih.gov/health/ health-topics/topics/hlw/system The main organs of the respiratory system are lungs, which carry out this exchange of gases as we breathe. The
➢ 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
“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 respiratory system provides a network of muscles and organs that helps a human breath. It brings in oxygen though inhaling and eliminates carbon dioxide through exhaling.
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.
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.
Nose is a convex feature lays in between and under our eyes, structured with bones, muscles, and flexible tissues named cartilage; with long thin nasal bones supporting the nose structure. Nostrils on nose are pathways for air to enter, and there grows nostril hair to prevent large particles to enter. The empty space
According to the e-book and what I read "The upper respiratory tract includes the nose, nasal cavity, sinuses, pharynx, larynx, and the upper portion of the trachea. The lower respiratory tract consists of the lower portion of the trachea, the bronchial tree, and the lungs."
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
