What is the nature of the respiratory system?

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. The lungs work with the circulatory system to pump oxygen-rich blood to all cells in the body.

What is the nature of respiration?

Respiration is the physiological process through which oxygen in the environment can be exchanged with carbon dioxide from an organism. This process requires specialized organs such as the lungs or gills. This oxygen is used for cellular respiration and metabolism, a byproduct of which is carbon dioxide.

Is the respiratory system complex?

The respiratory system is a structurally complex arrangement of organs designed principally for the intake of oxygen and the elimination of carbon dioxide, i.e., respiratory gas exchange or “respiration.” Though its main function is gas exchange, the respiratory tract is composed of specialized tissues and cells that ...

What are characteristics of respiratory system?

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 is the main function of respiratory system?

Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system's main job is to move fresh air into your body while removing waste gases.

What do you mean by cutaneous respiration?

Cutaneous respiration, or cutaneous gas exchange, is a form of respiration in which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs. Cutaneous respiration may be the sole method of gas exchange, or may accompany other forms, such as ventilation.

What are the 2 tracts that respiratory system has?

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 is the function of trachea in respiratory system?

What does the trachea do? Your trachea's main function is to carry air in and out of your lungs. Because it's a stiff, flexible tube, it provides a reliable pathway for oxygen to enter your body.

What are the 6 functions of the respiratory system?

The functions of the respiratory system include gas exchange, acid-base balance, phonation, pulmonary defense and metabolism, and the handling of bioactive materials.

What are the 3 parts of the respiratory system?

There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body's exterior.

What are the 4 types of respiration?

Key Takeaways: Types of Respiration

External respiration is the breathing process. It involves inhalation and exhalation of gases. Internal respiration involves gas exchange between the blood and body cells. Cellular respiration involves the conversion of food to energy.

What are gills?

Gills are branching organs located on the side of fish heads that have many, many small blood vessels called capillaries. As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that's dissolved in the water.

How do frogs breathe?

The frog has three respiratory surfaces on its body that it uses to exchange gas with the surroundings: the skin, in the lungs and on the lining of the mouth. ... A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs.

What are gills made up of?

The gill consists of branched or feathery tissue richly supplied with blood vessels, especially near the gill surface, facilitating the exchange of oxygen and carbon dioxide with the surrounding water.
