Hi..
here is your answer...
Human respiratory system includes nostril, nasal chamber, Phyranx, larynx , trachea , bronchi , bronchioles, lungs , diaphragm, and inter costal muscles.
● Nostril :--- Nostril are the external opening of the nose through which oxygen rich air is taken inside the body and carbon dioxide rich air containing water vapour is expelled outside the body. These are called external nares
● PHARYNX :--Nasal chamber open into the Phyranx. it is short , vertical tube measuring about 12cm in length. The respiratory and the food passages cross each other in the Phyranx by 2 separate passages.
● LARYNX :--- It is the sound producing organ. In males, the larynx increase in size at the time of puberty. Hence it is called Adam's apple and can noticed in the neck region. From the Phyranx air enters the larynx through an opening called glottis .
● TRACHEA :--- It is also known as wind pipe. It is about 12cm long and 2.5 cms wide. It lies in front of the oesophagus and extends downward into the neck . The wall of the trachea is made up of fibrous muscular tissue supported by C shaped cartilage rings.
● BRONCHIOLES :--- The distal end of the trachea is divided into two bronchi behind strenum . Each bronchus is supported by a complete ring of cartilage. It enters into the lung of its respective side.
LUNGS :--- These are the principal respiratory organs. lungs are paired , hollow, elastic organ. They are located in the thoracic cavity. Each lung is enclosed in a pleural sac . It is made up of 2 membrane, outer parietal and inner visceral.
hope it helps you. ☺
