The Human Respiratory system is a community of organs and tissues that capabilities to take oxygen in and expel carbon dioxide out of the physique.
The respiratory system is made up of the nostril, larynx, pharynx, bronchi, lungs and trachea.
Tell us in regards to the elements of the respiratory system to achieve a greater understanding.

Elements of the Respiratory System

• Nostril: The nostril is an exterior protuberance of an inside area known as the nasal cavity. It’s divided right into a proper and left aspect by a bony cartilaginous wall known as the septum. The nostrils open on the outer aspect of the physique and to the interior aspect via the pharynx. The nostrils are lined with hairs that act as the primary line of defence in opposition to pathogens.
• Larynx: The larynx serves as an air canal to the lungs. Additionally it is known as the voice field of the human physique as a result of it aids in phonation. It resides within the entrance of the neck.
• Pharynx: The nostrils open into the vast area of the pharynx. It’s divided into three flooring, the nasopharynx that acts as a passageway for the secretions from the nostril. The center flooring or the oropharynx connects the pharynx to the mouth, and the decrease flooring or the hypopharynx that connects to the tongue. Epiglottis, a flap-like construction, acts as a lid and prevents the entry of meals and liquids.
• Trachea: It lies slightly below the larynx and is a tube-like construction embedded in dense connective tissue. Additionally it is often called the windpipe. It has 16-20 incomplete horseshoe-shaped cartilaginous rings that give it a stiffened look.
• Bronchi: The trachea, on the decrease finish, divides into two inverted Y formed bronchi, one in the direction of the suitable and the opposite in the direction of the left aspect. It additional branches out into sacs known as alveoli. The alveoli assist in the trade of gases to and from the bloodstream.
• Lungs: The lungs are the chief organ for the method of respiration. It’s positioned within the thoracic cavity of the chest and is superficially divided right into a proper and left lung. It facilitates the trade of gases together with different elements of the respiratory system.
• Diaphragm: The diaphragm is a muscle positioned under the lungs that may be a main muscle for respiration. It contracts and relaxes regularly and rhythmically to assist inhalation and exhalation.

Capabilities of the Respiratory System

• It helps in inhalation and exhalation.
• It helps us to speak and likewise scent.
• It delivers oxygen to all elements of the physique.
• It protects the physique by stopping the entry of dangerous substances.

This sums up the anatomy and performance of the respiratory system. On this article, we learnt about all of the completely different elements of the respiratory system and the capabilities they carry out.
