What system contains the air passages and lungs?

What system contains the air passages and lungs?

The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels.

Which body system is responsible for housing the lungs?

The human respiratory system is a network of organs responsible for taking in oxygen and expelling carbon dioxide. Its primary organs are the lungs, which carry out this exchange of gases as we breathe.

What houses the lung?

The lungs are enclosed by the pleura, a membrane that is composed of visceral and parietal pleural layers. The space between these two layers is called the pleural cavity.

What is the main passage of air for the lungs?

The windpipe (trachea) is the largest airway. The trachea branches into two smaller airways: the left and right bronchi, which lead to the two lungs.

How do the respiratory and the circulatory system work independently and together?

The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

What cavity houses the spinal cord?

The posterior (dorsal) and anterior (ventral) cavities are each subdivided into smaller cavities. In the posterior (dorsal) cavity, the cranial cavity houses the brain, and the spinal cavity (or vertebral cavity) encloses the spinal cord.

What structures make up the lungs?

The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.

Where is the lung base located?

Each lung has a base resting on the diaphragm and an apex extending superiorly to a point approximately 2.5 cm superior to the clavicle. It also has a medial surface and with three borders- anterior, posterior and inferior.

What are lungs respiratory system?

Overview. The lungs are the center of the respiratory (breathing) system. Every cell of the body needs oxygen to stay alive and healthy. Your body also needs to get rid of carbon dioxide. This gas is a waste product that is made by the cells during their normal, everyday functions.

Where does the air enter the respiratory system?

The respiratory system includes the nose, mouth, trachea, bronchi, diaphragm and lungs. Air enters the body through either the open mouth or the nose. It travels down the trachea to the lungs, where the oxygen in it passes into the bloodstream. Air enters the body through either the open mouth or the nose.

Are there any other systems that work with the respiratory system?

Other body systems that work with the respiratory system include the nervous system, lymphatic system, and immune system. The Respiratory System. The image shows an enlarged view of the airways and lungs as well as the trachea; bronchial tubes, or bronchi; and bronchioles. The image also shows a close-up view of gas exchange at the alveoli.

Where does sound come from in the respiratory system?

When we speak, yell, or sing, air coming up from the lungs and trachea vibrates the folds, producing the sound. Phonation is the creation of sound by structures in the upper respiratory tract of the respiratory system. During exhalation, air passes from the lungs through the larynx, or “voice box.”

Is the trachea part of the respiratory system?

The respiratory system or respiratory tract can be divided into two major parts: the upper and the lower respiratory tracts. The upper respiratory tract includes the following structures: trachea. The nose consists of its visible (outer) part and the nasal cavity.
