Water, carbon dioxide and oxygen can enter a cell through the plasma membrane.
Oxygen can enter the atmosphere during celluar respiration, because if it enters photosynthesis, how about the other organisms?
Gases And Oxygen
Glucose and Oxygen
It enter when you breathe. You let go of Carbon in your body when you breathe out, and let fresh air or oxygen enter your body when you breathe in.
Through the muscles
Oxygen enter the capillaries by diffusion due to difference in oxygen concentrations.
your muscles take over your neuromuscular body structure therefore causing an extremley irritating rash on your insilin sack. your bodys enzymes cannot function correctly and you turn into a motionless body but can only move abdominals and gluteus maximus muscles almost similar to a worm.
* Faster heart rate - pumps more blood around your body. Your blood carries oxygen which is needed by muscles for aerobic respiration. * Faster breathing rate - allows more oxygen to enter the blood. * Deeper breaths - more volume per breath relatively, so that muscles get as much as possible in order to respire aerobically.
Oxygen enters via the lungs.
capillaries

The lung or pulmonary system is the essential respiration organ that makes it possible for oxygen to enter the circulatory system.The alveoli struture makes it possible for oxygen to enter the circulatory system.
