Oxygen
The connection between plants and oxygen is that after the plant is done making photosynthesis it releases oxygen into the air and takes in carbon dioxide that we release into the air. So we are the ones who take in oxygen from the plant. This is a reason why we should not cut down a handful of trees otherwise there will be less oxygen in the air.
False. cellular respiration is a chemical process by which oxygen is used along with other stuff to create energy and release carbon-dioxide. physical respiration is nothing more than the relaxing and contracting of the diaphragm to bring air into and out of the lungs.
the breaths we take
The organ that takes in oxygen is the lungs. While in breathing process, oxygen passes through the lungs from the air by means of inhaling.
Respiration involves the lungs. The lungs inflate with air, and this allows oxygen into the lungs. The windpipe and mouth and nose are also involved in respiration.
Lungs
In the process of respiration OXYGEN is taken in from the atmoshpere and CO2 is released.
aerobic respiration
Oxygen is a product of respiration by plants that contain chlorophyll and consume carbon dioxide. Oxygen is a reactant in respiration by air-breathing animals.
Aerobic means with oxygen/air. Anaerobic means without oxygen/air.
The lungs remove oxygen from the air.
the air
Blood capillaries surrounding air sacs called alveoli.
People need to breathe, and so do lots of other animals—and plants! Breathing is part of a process called respiration. During respiration, a living thing takes in oxygen from the air and gives out carbon dioxide
