when it reaches tissues and cells that are low on oxygen
A lower than normal level of oxygen is called hypoxia.
An increase in diffusion rates in tissues favours oxygen movement from the capillaries to the tissues, and carbon dioxide from the cells to the blood. Also With some training these rates increase, allowing oxygen and carbon dioxide to diffuse more rapidly.
The main function of red blood cells is to transport oxygen to tissues from the lungs and carbon dioxide out from the tissues to the lungs to breathed out of the body
it doesnt
Blood releases its oxygen into the tissues at the capillary level.
Smoking affects the oxygen-carbondioxide exchange capacity of the lungs. For a wound to heal, various factors are required, the most important of which is oxygen. In smokers, the amount of oxygen that reaches tissues is subnormal. This will retard wound healing.
oxygen and gravity
The oxyhaemoglobin will break down and oxygen will release. :)
The primary factor that determines how much oxygen is actually bound to hemoglobin is the partial pressure of oxygen (pO2) in the hemoglobin solution.
-Decreased pH -Increased Temperature -Increased Pco2
they give out oxygen
Oxygen
An increase in diffusion rates in tissues favours oxygen movement from the capillaries to the tissues, and carbon dioxide from the cells to the blood. Also With some training these rates increase, allowing oxygen and carbon dioxide to diffuse more rapidly.
There are three factors... 1) Temperature 2) Pressure 3) The presence of Oxygen
Temperature Dissoved Oxygen pH level
The tissues get oxygen from oxygenated blood supply for energy production.
