It's so important to life that it happens automatically. If you didn't breathe, you couldn't live. Each day we breathe about 20, times. All of this breathing couldn't happen without help from the respiratory system, which includes the nose, throat, voice box, windpipe, and lungs. With each breath, you take in air through your nostrils and mouth, and your lungs fill up and empty out. As air is inhaled, the mucous membranes of the nose and mouth warm and humidify the air.
NCBI Bookshelf. The blood circulatory system cardiovascular system delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart. The smallest arteries end in a network of tiny vessels known as the capillary network. There isn't only one blood circulatory system in the human body, but two, which are connected: The systemic circulation provides organs, tissues and cells with blood so that they get oxygen and other vital substances.

Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body. At the same time, carbon dioxide that is dissolved in the blood comes out of the capillaries back into the air sacs, ready to be breathed out. Blood with fresh oxygen is carried from your lungs to the left side of your heart, which pumps blood around your body through the arteries. Blood without oxygen returns through the veins, to the right side of your heart. From there it is pumped to your lungs so that you can breathe out the carbon dioxide and breathe in more oxygen. This information uses the best available medical evidence and was produced with the support of people living with lung conditions.
Learn about The Nobel Prizes that have been awarded since , as well as the criteria and nomination process that are used to select the winners. NASA Kids is an excellent site for "kids" of all ages and provides an abundance of information, images, and interesting things to do on astronomy and the space sciences. In this lesson, students learn about sources of high-energy radiation and calculate student exposure to ionizing radiation over the past year. To understand that human beings as well as other animals perform the respiration process because we need air to breathe and because oxygen is ultimately the fuel that allows our cells to produce energy from the food we eat. The main focus of this lesson is to review the basics of respiration breathing and to teach students the importance of oxygen to the human body. To burn food for the release of energy stored in it, oxygen must be supplied to cells, and carbon dioxide removed.
The primary function of the respiratory system is to take in oxygen and eliminate carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli. The layers of cells lining the alveoli and the surrounding capillaries are each only one cell thick and are in very close contact with each other. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled. Oxygenated blood travels from the lungs through the pulmonary veins and into the left side of the heart, which pumps the blood to the rest of the body see Function of the Heart.

Exchanging Oxygen and Carbon Dioxide
Energy is needed for life processes such as:. Respiration is a chemical reaction that happens in all living cells, including plant cells and animal cells. It is the way that energy is released from glucose so that all the other chemical processes needed for life can happen. Do not confuse respiration with breathing which is properly called ventilation. Glucose and oxygen react together in cells to produce carbon dioxide and water and releases energy. The reaction is called aerobic respiration because oxygen from the air is needed for it to work.
The carbon dioxide breathed out is a by-product of the process of cell respiration, as is water. In this process, energy is produced in the mitochondria of cells. This energy is our physical "life force". Both oxygen and glucose are required for this. Glucose contains carbon. That's where the carbon in carbon dioxide comes from. Glucose plus oxygen produces carbon dioxide, water and energy.
The human respiratory and circulatory systems work together to supply the body with oxygen and get rid of waste carbon dioxide. While the former deals with air and the latter with blood, they work together seamlessly by coordinating the functions of the many parts of each system. Other systems in the body, such as the digestive system and the nervous system, are important too, but the circulatory and respiratory systems have to work continuously, usually without pausing even for a few minutes. The circulatory and respiratory systems absorb oxygen from the air and transfer it to all parts of the body while absorbing carbon dioxide from the body and releasing it into the air. When a person inhales, the lungs expand and fill with fresh air. The respiratory system interacts with the circulatory system to transfer oxygen from fresh air to red blood cells in the lung arteries while also releasing carbon dioxide from the blood into the air in the lungs. When a person exhales, this used air leaves the body.
Carbon dioxide is a chemical compound composed of one carbon and two oxygen atoms. Atmospheric carbon dioxide derives from multiple natural sources including volcanic outgassing, the combustion of organic matter, and the respiration processes of living aerobic organisms; man-made sources of carbon dioxide come mainly from the burning of various fossil fuels for power generation and transport use. Plants convert carbon dioxide to oxygen during a process called photosynthesis, using both the carbon and the oxygen to construct carbohydrates. In addition, plants also release oxygen to the atmosphere, which is subsequently used for respiration by heterotrophic organisms, forming a cycle. Reference Terms. It is often referred to by its formula CO2.
