you are not breathing enough to oxidize your blood
It falls because the muscles no longer need all the oxygen your heart was sending to them.
The venous reserve of oxygen in the blood allows for a safety margin and helps maintain tissue oxygenation during periods of increased oxygen demand or decreased oxygen delivery. It ensures that tissues receive a continuous supply of oxygen even when there are fluctuations in oxygen levels in the body.
Blood volume also falls.
During photosynthesis, green plants take in carbon dioxide and water, using sunlight to produce glucose and oxygen as byproducts. Oxygen is released into the atmosphere as a waste product during this process.
Blood falls under the circulatory system. It is responsible for delivering oxygen, nutrients, and hormones to cells and tissues throughout the body. Additionally, blood helps remove waste products and carbon dioxide from the body.
A normal blood oxygen saturation level for a non-smoker is typically around 95-100%. Smoking can reduce this level by introducing carbon monoxide into the bloodstream, which competes with oxygen for binding to hemoglobin. Blood oxygen saturation is considered impaired when it falls below 90%. For further information and resources, you may refer to medical websites such as the American Lung Association or Mayo Clinic.
Ozone is created by the oxygen molecules. When the UV falls on oxygen, ozone is formed.
A pulse oximeter is often used to monitor oxygen levels in a baby's blood shortly after birth. If the baby's oxygen saturation falls below a certain level, supplemental oxygen may be required. Additionally, clinical assessment of the baby's respiratory effort and color can help determine the need for oxygen supplementation.

Concentration gradient moves oxygen and carbon dioxide across the alveolar membrane. Blood that enters the alveolus has a higher concentration of carbon dioxide compared to the air in our lungs; so the carbon dioxide literally falls out of the blood and into the air. Blood that enters the alveolus has a lower concentration of oxygen than the air in our lungs, so the oxygen falls into solution with our blood and is carried back to the heart for distribution to our bodies. This process is passive, meaning that no energy is required for the gasses to move. They are merely seeking to equalize their own concentrations across a semi-permeable membrane. This passive diffusion drives many processes in our bodies.
