The respiratory tract is divided into two main parts: the upper respiratory tract, consisting of the nose, nasal cavity and the pharynx; and the lower respiratory tract, consisting of the larynx, trachea, bronchi
Bronchus
A bronchus is a passage of airway in the respiratory system that conducts air into the lungs. The first bronchi to branch from the trachea are the right main bronchus and the left main bronchus. These are the widest and enter the lungs at each hilum, where they branch into narrower secondary bronchi or lobar bronchi, and these branch into narrower tertiary bronchi or segmental bronchi.

What is the physiology of the respiratory system?
The respiratory system, which includes air passages, pulmonary vessels, the lungs, and breathing muscles, aids the body in the exchange of gases between the air and blood, and between the blood and the body's billions of cells. Organs in the respiratory system also play a role in speech and the sense of smell.
What are the most important organs in the respiratory system?
Your airways are a complicated system that includes your:
- Mouth and nose: Openings that pull air from outside your body into your respiratory system.
- Sinuses: Hollow areas between the bones in your head that help regulate the temperature and humidity of the air you inhale.
- Pharynx (throat): Tube that delivers air from your mouth and nose to the trachea (windpipe).
What are the main structures of the respiratory system?
- Trachea: Located just below the larynx, the trachea is the main airway to the lungs.
- Lungs: Together the lungs form one of the body’s largest organs. ...
- Bronchi: The bronchi branch from the trachea into each lung and create the network of intricate passages that supply the lungs with air.
What are the major tissues in the respiratory system?
Tissues That Make Up The Respiratory System ... The oropharynx consists of stratified squamous epithelium and the laryngopharynx consists of respiratory pseudostratified. Clusters of lymphatic tissue called TONSILS are found in the pharynx. High in the nasopharynx is the PHARYNGEAL TONSILS (adenoid).
What are the two main parts of the respiratory system?
The respiratory tract is divided into two main parts: the upper respiratory tract, consisting of the nose, nasal cavity and the pharynx; and the lower respiratory tract, consisting of the larynx, trachea, bronchi and the lungs.

What are the parts of the respiratory system?
The respiratory system includes the nose, mouth, throat, voice box, windpipe, lungs, and diaphragm.
What are the parts of respiratory system and its function?
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 are the organs and their functions of the respiratory system quizlet?

How many organs are in the respiratory system?
sixThe respiratory system is composed of six major organs: the nasal cavity, the pharynx, the larynx, the trachea, the bronchi, and the lungs.
Which is not part of the respiratory system?
Answer. Any other organ except the wind pipe, larynx, pharynx, trachea, lungs, bronchi, bronchioles, and the alveoli are not part of the respiratory system.
What is the main process of the respiratory system?
When you inhale (breathe in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out). This process, called gas exchange, is essential to life.
What are the three major organs of the respiratory system located in the head and throat?
Nose. The nose detects odor molecules and helps filter and warm the air we inhale. The upper respiratory system, or upper respiratory tract, consists of the nose and nasal cavity, the pharynx, and the larynx.
Which of the following is not part of the respiratory system?
Medulla Oblongata is not a part of the respiratory system.
What are the main muscles of breathing?
From a functional point of view, there are three groups of respiratory muscles: the diaphragm, the rib cage muscles and the abdominal muscles. Each group acts on the chest wall and its compartments, i.e. the lung-apposed rib cage, the diaphragm-apposed rib cage and the abdomen.
Why is the respiratory system important?
The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells.
How many zones are there in the respiratory system?
