Asphyxia .
Oxygen enters the bloodstream through the alveoli in the lungs. When you breathe, oxygen from the air diffuses across the thin walls of the alveoli into the surrounding capillaries, where it binds to hemoglobin in red blood cells for transport throughout the body.
The stomach does not take in air as its primary function. However, it is possible for air to enter the stomach when swallowing food or beverages, which can lead to bloating or flatulence.
Saturation happens when the air cannot hold any more water vapor, leading to condensation and the formation of clouds or precipitation. It can occur when the temperature of the air drops, when moisture is added to the air, or when the air is cooled to its dew point.
Examples of substances that enter the body include nutrients from food, oxygen from the air we breathe, and medications. Substances that leave the body include carbon dioxide when we exhale, waste products such as urine and sweat, and toxins removed by the liver.
Radioactive isotopes can enter the body primarily through inhalation, ingestion, and absorption through the skin. Inhalation occurs when radioactive particles are breathed in, often from contaminated air. Ingestion happens when radioactive materials are consumed through food, water, or contaminated surfaces. Absorption can occur when radioactive substances come into contact with the skin or through wounds.
Air can enter the body by the mouth or the nose. Air then goes down the windpipe to the lungs where it can enter the bloodstream.
To oxygenise the body.
lungs
Diaphram
Two air passages which allow air to enter the body are the cilia and aveoli !!!
To allow the air to enter the body. The air can enter through either the nose or through the mouth.
To allow the air to enter the body. The air can enter through either the nose or through the mouth.
Spiracles
Pollution enters the system by respiration. When you breathe in your body uses the oxygen in the "air". But when pollution is in the "air", your body takes that in and enters the Ovules of the lung and enter your blood stream.
As the diaphragm contracts, air enters the body through the nose and mouth.
THE NOSE AND OF COURSE THE MOUTH..................
Mouth and nose
