function of different structure in the human respiratory system?
Answers
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
☆What is the Respiratory System?
The human respiratory system consists of a group of organs and tissues that help us to breathe. Lungs are the primary organs of the respiratory system which help in the exchange of gases. The other main parts of this system include a series of airways for air passages, blood vessels and the muscles that facilitate breathing.
☆The respiratory system in humans is made up of the following parts and their functions:
•External nostrils – For the intake of air.
•Nasal chamber – which is lined with hair and mucus to filter the air and remove dust and dirt.
•Pharynx – It is a passage behind the nasal chamber and serves as the common passageway for both air and food.
•Larynx – Also known as the soundbox as it helps in the generation of sound and thus helps us in communicating.
•Epiglottis – It is a flap-like structure that covers the glottis and prevents the entry of food into the windpipe.
•Trachea – It is a long tube passing through the mid-thoracic cavity.
•Bronchi – The trachea divides into left and right bronchi.
•Bronchioles – Each bronchus is further divided into finer channels known as bronchioles.
•Alveoli – The bronchioles end up into the balloon-like structures known as the alveoli.
•Lungs – We have a pair of lungs, which are sac-like structures and covered by a double-layered membrane known as pleura.
☆How do we breathe?
When we breathe, we inhale oxygen and exhale carbon dioxide. The so-called exchange of gases is necessary for metabolic activities and can be considered a chemical process.
Every organism, from an individual bacterial cell to a mighty blue whale, undergoes respiration. This respiration is carried out by a system of organs known as the Respiratory System and the respiration in humans is carried out by the human respiratory system.
