I need help with science I am a fifth grader who is a bit good at science on certain questions.
The respiratory system absorbs oxygen. Oxygen is inhaled through the nose and mouth, passes through the trachea, and enters the lungs where it is absorbed into the bloodstream through tiny air sacs called alveoli.
No, oxygen is not an organ at all. It's a gas. However, it is inhaled and exhaled through the respiratory system.
Inhaled air is typically warmed and humidified as it passes through the nasal passages. The purpose of this process is to protect the delicate tissues of the respiratory system from damage due to cold and dry air.
air is filtered, warmed, and moistened.
The respiratory system.
In the lower respiratory system, air that has been filtered of pathogens and warmed in the upper respiratory tract is transported to the lungs. There, oxygen will be pulled from the inhaled air and deposited into the bloodstream, while carbon dioxide pulled from the bloodstream is released back into the lungs to be expelled from the body upon exhaling. This exchange of gases is the primary function of the respiratory system.
Water vapor will increase in exhaled air compared to inhaled air because the air we breathe in gets warmed and humidified as it passes through our respiratory system, leading to an increase in water vapor content when we exhale.
Air passes through various mediums such as the atmosphere, respiratory systems of living organisms, and ventilation systems in buildings. In the atmosphere, air moves freely, influenced by temperature and pressure changes. In the respiratory system, air is inhaled through the nose or mouth, passing through the trachea and into the lungs for gas exchange. In buildings, air moves through ducts and filters to maintain indoor air quality and temperature.
The body is supplied with oxygen by the respiratory system through the process of breathing. Oxygen is inhaled through the nose or mouth, travels down the trachea, and then enters the lungs where it is taken up by the bloodstream to be transported to body tissues for energy production.
yes it will pollutants that can be inhaled can affect respiratory system
Air inhaled through the mouth is not as clean as air inhaled through the nose. Reason for this is that when we inhale air through our nose than it get filtered by hair present in our nose. But air inhaled through our mouth goes directly in without any filtration.
Oxygen is inhaled through the respiratory system and diffuses into the bloodstream through the alveoli in the lungs. It then binds to hemoglobin in red blood cells and is transported throughout the body via the circulatory system. Oxygen is delivered to tissues and cells where it is used for cellular respiration to produce energy.
