Question

Explain human respiratory system without leaving any single thing if class 11th PLZZZ BUDDIES

Answer 1

Hi.....
Human respiratory system is a very important system of human body...
Respiratory system helps in breaking of glucose in body and also the exchange of gases in the human body.'ll,
Respiratory system consist of the Nose, nostrils , larynx , windpipe , lungs , bronchioles, bronchus, trachea and etc. ..
It consist of two process that are exhalation and Inhalation. ....
these process help in transportation of oxygen in blood capillaries and removal of toxic gases like carbon dioxide from the body.....
Respiration process helps in breaking down of food for the production of energy in the body by the aerobic and the anaerobic respiration processes...
The human gas-exchanging organ, the lung, is located in the thorax, where its delicate tissues are protected by the bony and muscular thoracic cage. The lung provides the tissues of the human body with a continuous flow of oxygen and clears the blood of the gaseous waste product, carbon dioxide. Atmospheric air is pumped in and out regularly through a system of pipes, called conducting airways, which join the gas-exchange region with the outside of the body. The airways can be divided into upper and lower airway systems. The transition between the two systems is located where the pathways of the respiratory and digestive systems cross, just at the top of the larynx.
The upper airway system comprises the nose and the paranasal cavities (or sinuses), the pharynx (or throat), and partly also the oral cavity, since it may be used for breathing. The lower airway system consists of the larynx, the trachea, the stem bronchi, and all the airways ramifying intensively within the lungs, such as the intrapulmonary bronchi, the bronchioles, and the alveolar ducts. For respiration, the collaboration of other organ systems is clearly essential. The diaphragm, as the main respiratory muscle, and the intercostal muscles of the chest wall play an essential role by generating, under the control of the central nervous system, the pumping action on the lung. The muscles expand and contract the internal space of the thorax, the bony framework of which is formed by the ribs and the thoracic vertebrae. The contribution of the lung and chest wall (ribs and muscles) to respiration is described below in The mechanics of breathing. The blood, as a carrier for the gases, and the circulatory system (i.e., the heart and the blood vessels) are mandatory elements of a working respiratory system.....
basically respiratory system is responsible for the conditional working of the body.....

Answer 2

The primary organs of the respiratory system are the lungs, which function to take in oxygen and expel carbon dioxide as we breathe.

The gas exchange process is performed by the lungs and respiratory system. Air, a mix of oxygen and other gases, is inhaled.

In the throat, the trachea, or windpipe, filters the air. The trachea branches into two bronchi, tubes that lead to the lungs.

Once in the lungs, oxygen is moved into the bloodstream. Blood carries the oxygen through the body to where it is needed.

Red blood cells collect carbon dioxide from the body’s cells and transports it back to the lungs.

An exchange of oxygen and carbon dioxide takes place in the alveoli, small structures within the lungs. The carbon dioxide, a waste gas, is exhaled and the cycle begins again with the next breath.

The diaphragm is a dome-shaped muscle below the lungs that controls breathing. The diaphragm flattens out and pulls forward, drawing air into the lungs for inhalation. During exhalation the diaphragm expands to force air out of the lungs.

Adults normally take 12 to 20 breaths per minute. Strenuous exercise drives the breath rate up to an average of 45 breaths per minute.
