what is human respiratory system made of?

The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs.
585456
Most biomolecules are organic compounds, and just four elements—oxygen, carbon, hydrogen, and nitrogen—make up 96% of the human body's mass.

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.

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 respiratory system is lined with a mucous membrane that secretes mucus. The mucus traps smaller particles like pollen or smoke. Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose.

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.

Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen, with a lot of that in the form of water. The remaining 4 percent is a sparse sampling of the periodic table of elements.
390428
The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe.
340953
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 mucus traps smaller particles like pollen or smoke.

Normally, humans breathe in air that is approximately 20.95% oxygen, 78.09% nitrogen, 0.93% argon, and 0.04% (400 ppm) of carbon dioxide. Like CO2, oxygen also dissolves in the lungs and is transported to the blood via diffusion across the lung tissue (alveoli).

Nose. The nose is the body's primary organ of smell and also functions as part of the body's respiratory system.

The chest wall consists of the muscles of respiration—such as the diaphragm, the intercostal muscles, and the abdominal muscles—and the rib cage. The functions of the respiratory system include gas exchange, acid-base balance, phonation, pulmonary defense and metabolism, and the handling of bioactive materials.
678443
The respiratory system supplies oxygen to the blood and removes carbon dioxide. The brain monitors respiratory volume and blood gas levels. The brain regulates respiratory rate.

The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
1083197
The rest of the circulatory system is made up of two independent networks that work together: The pulmonary and systemic systems. The pulmonary system is responsible for providing fresh oxygen to the blood and removing carbon dioxide, according to the National Center for Biotechnology Information (NCBI).

The Role of the Respiratory System is to breathe in oxygen and breathe out carbon dioxide. This is known as respiration. The cells of the body use oxygen to perform functions that keep us alive. The waste product created by the cells once they have performed these functions is carbon dioxide.

The particles we're made of About 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. ... If we lost all the dead space inside our atoms, we would each be able to fit into a particle of lead dust, and the entire human race would fit into the volume of a sugar cube.
