Human being have lungs for respiration. So respiration in human beings is know as pulmonary respiration.Respiratory organs are well developed in human being.The respiratory system consists of repiratory tract and respiratory organs.The repiratory tract is passage along whcih air travels from the atmosphere in order to reach lungs.
The nasal cavaty:- Nasal cavity lies above the mouth cavity. Tye nasal cavity communicate to the outside through external nostrils and internally with the pharynx by internal nostrils. Both cilia and mucus check the entry of dust particles in the respiratory passage.
The Pharynx: The pharynx is the next stop for air after the nasal cavity. The glottis is the mechanism by which the pharynx opens into the larynx or voice box. The glottis also serves another important purpose. Because the digestive and respiratory tract both share the pharynx, the glottis is covered by the leaf like cartilage epiglottis when we swallow food, which prevents food getting into the respiratory system.
Larynx:- It is cartilagious box like structure located at the tracheal opening. When we swallow some food material,the larynx moves up or down to allow safe passage of air or food. Larynx contains two vocal chords which vibrate and produce sound while we speak.
The Trachea: The trachea is the next organ through which air flows. This is a tube that is eleven centimeters in length with a twenty five centimeter diameter. In order to keep the trachea opened, there is an incomplete C-shaped cartiligious ring within the trachea wall.
Bronchi and Bronchioles:- At its lower end, the trachea splits into two primary bronchi.The right bronchus is divided in three bronchi which extend seperatly into the three lobies of right lung.Similarly the left bronchi is divided into two bronchi penetrating into the two lobies of left lung.
The Lungs: Lungs are an elastic, spongy, bag like structure, that is hollow. There are two lungs, both located in the thoracic cavity. The thoracic cavity is surrounded by the vertebral column, the sternum, and the diaphragm. The diaphragm form the floor of the cavity, so they are what our lungs rest on.
The right lung is divided into three lobies whereas the left lung has two lobies.The lungs are sorrounded by a narrow shape called pleural cavaty.There are two membranes around pleural cavaty.These membrane secret an oily fluid called pleural fluid.Pleural cavity is filled with pleural fluid. - 15431
