Pulmonary Surfactant: Mainly consisting of phospholipids, pulmonary surfactant is responsible for reducing the surface tension within the alveoli to prevent them, and the lungs in turn, from collapsing when the air rushes out during expiration [21, 22]. Respiratory System Functions.
How does the digestive system work?
The digestive, circulatory, and respiratory systems all work together, with the digestive system keeping the other two healthy by sending enough nutrients, so the lungs can continue to exchange oxygen for carbon dioxide and the blood vessels can carry this oxygen to the whole body, including the digestive tract.
What is the function of the pulmonary alveoli?
This is the part of the respiratory system that carries out the gas exchange process [19]. There is a network of blood capillaries surrounding each alveolus.
What is the function of the respiratory system?
What is the function of respiratory system? The respiratory system is a progression of organs in charge of taking in oxygen and releasing out the carbon dioxide. The essential organs of the respiratory framework are lungs, which complete this trade of gasses as we breathe.
What are the essential organs of the respiratory framework?
The essential organs of the respiratory framework are lungs, which complete this trade of gasses as we breathe. RBC's gather the oxygen from the lungs and convey it to the parts of the body where it is required, as indicated by the American Lung Association.
How is carbon dioxide pumped into the alveoli?
The carbon dioxide from deoxygenated blood diffuses from the vessels into the alveoli and is removed through exhalation.
How does oxygen exchange between blood and lungs?
Exchange of Gasses between Lungs and Blood − Inside the lungs, oxygen is traded for carbon dioxide through the procedure called external breathing. This respiratory procedure happens through countless minuscule sacs called alveoli. Oxygen from intake air diffuses from the alveoli into pulmonary vessels encompassing them.
What is the process of air vibrating the vocal cords?
Air Vibrating the Vocal Cords Creates Sound − Phonation is the production of sound by structures in the upper respiratory tract of the respiratory system. While exhaling, air goes from the lungs through the larynx, or "voice box.". When we talk, muscles in the larynx move the arytenoid ligaments.
What system is responsible for the exchange of gases between blood and body tissues?
Exchange of Gasses between Bloodstream and Body Tissues − The circulatory system conveys oxygen to cells and eliminates carbon dioxide through respiration. The red platelets convey oxygen assimilated from the lungs around the body, through the vasculature. At the point when oxygenated blood reaches the vessels, the RBC's discharge the oxygen.
Which system helps in breathing?
Inhalation and Exhalation − The respiratory system helps in breathing, likewise called pulmonary ventilation. Air is breathed in through the nose and mouth. It travels through the pharynx, larynx, and trachea into the lungs.
What is the respiratory system?
Your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood. Common problems include allergies, diseases or infections.

You should also know that many conditions and illnesses can affect the respiratory system, some of the common problems include: - 1 Asthma – Asthma leads to a narrowing of the airways, which can cause breathlessness and wheezing. 2 Bronchitis – A condition that causes inflammation of the mucus lining within the one lung or both. 3 Emphysema – A disease that affects alveoli. 4 Influenza – An illness caused by a virus that can have a detrimental affect on one’s respiratory system. 5 Laryngitis – When one’s vocal chords (larynx) become inflamed. 6 Pneumonia – When one or both lungs become inflamed. 7 Lung cancer – Although commonly associated with smokers, lung cancer can also affect those who do not smoke.
Why is it important to inhale air through the mouth?
Inhaling air through the mouth allows more inhalation, as the oral cavity is far larger than the nasal cavity. The air also has less distance to travel, meaning more air can enter your body and be used faster. The oral cavity has no hairs or filtering techniques, meaning the air you inhale does not undergo the filtration process.
What is the purpose of the nose?
The nose is used to inhale air into the body. The nasal cavity warms the air as it enters, acting as filtration and purifying the air by removing any dust, pollen, and other contaminants, before it passed to the inner body. Also called the oral cavity, the mouth is the secondary exterior opening for the respiratory system.
What is the name of the tube that connects the windpipe to the lungs?
Bronchi. The bronchi are two tubes stemming off of the end of the trachea. Each tube is connected to a lung. The bronchi connect the wind pipe to the lungs, allowing air from external respiratory openings to pass efficiently into the lungs.
Why does air flow into the lungs?
Because air pressure outside of the lungs is now greater than inside (where there is negative pressure), air will naturally flow into the lungs.
Which part of the rib cage opens and expands the lungs?
The motion of the rib cage: the rib cage lifts superiorly and anteriorly to open and expand the lungs.
