Nose, the prominent structure between the eyes that serves as the entrance to the respiratory tract and contains the olfactory organ. It provides air for respiration, serves the sense of smell, conditions the air by filtering, warming, and moistening it, and cleans itself of foreign debris extracted from inhalations.

The respiratory zone corresponds to the lung parenchyma and includes the respiratory bronchioles, alveolar ducts, and alveoli. The lower respiratory system is a hierarchical system that can be divided into two functional and structural components: the conducting tract (airways) and the respiratory zone.

The lower respiratory system, or lower respiratory tract, consists of the trachea, the bronchi and bronchioles, and the alveoli, which make up the lungs. These structures pull in air from the upper respiratory system, absorb the oxygen, and release carbon dioxide in exchange.

Such structures include the nasal cavity, pharynx, larynx, trachea, and most of the bronchial tree. The respiratory zone includes all the organs and structures that are directly involved in gas exchange, including the respiratory bronchioles, alveolar ducts, and alveoli.

Upper respiratory tract organs provide a route for air to move between the outside atmosphere and the lungs. They also clean, humidity, and warm the incoming air. However, no gas exchange occurs in these organs.

KEY CONCEPT The respiratory and circulatory systems bring oxygen and nutrients to the cells. The respiratory and circulatory systems work together to maintain homeostasis. The respiratory system moves gases into and out of the blood.

The major passages and structures of the upper respiratory tract include the nose or nostrils, nasal cavity, mouth, throat (pharynx), and voice box (larynx). The respiratory system is lined with a mucous membrane that secretes mucus.

The terminal parts of the bronchi are the alveoli. The alveoli are the functional units of the lungs and they form the site of gaseous exchange.

It has two major divisions: the upper respiratory tract and the lower respiratory tract. The upper respiratory tract includes the nasal cavity, pharynx, and larynx.

The parts of the respiratory system The respiratory system is divided into two parts: Upper respiratory tract: This includes the nose, mouth, and the beginning of the trachea (the section that takes air in and lets it out).

The lungs are the largest organs of the respiratory tract. ... Lung tissue consists mainly of alveoli (Figure 16.2.6). These tiny air sacs are the functional units of the lungs where gas exchange takes place.

The main parts of the system are the heart, arteries, capillaries and veins. The circulatory system does a very important job in your body. It carries oxygen and essential nutrients to all cells around the body in arteries and carries the waste products and carbon dioxide in veins.

Lungs play a major role in the respiratory system. In humans, a pair of lungs are designed in such a way that they are lined by a thin membrane, the smaller tubes called bronchioles a balloon-like structure called alveoli and network of blood capillaries increase the surface area for exchange of gases.

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.
