Hypoxia is the term used for low, or depleted, oxygen levels. It occurs naturally at high altitudes or in the deeper regions of the sea.
worn out, drained, spent, bushed, fatigued, spent, finished, depleted, dissipated, expended
Depleted.
I don't know! (it means its running out ; example: all the vitamins in my body are depleted)
The antonym of oxygen is a solid.
Hypoxia: Hypo = below, ox = presence of oxygen "Below oxygen" or "below normal oxygen levels" Hypoxia means low tissue oxygen level. Or oxygen levels below normal in the tissues.
Veins carry oxygen depleted blood to the heart.
Oxygen-depleted blood can be found in the veins, as it has already delivered oxygen to the body's tissues and is returning to the heart to be reoxygenated in the lungs.
an oxygen debt
This is through the Pulmonary Circulation.
By definition, ALL arteries carry Oxygen rich blood. Veins carry oxygen depleted blood.
None. It remains balanced thanks to photosynthesis.
A body of water can be depleted of oxygen by excessive nutrient runoff (eutrophication), which leads to algal blooms that consume oxygen as they decompose. Pollution from industries or sewage can also introduce harmful substances that reduce oxygen levels in the water. Additionally, temperature changes and natural processes like decomposition can contribute to oxygen depletion.
The pulmonary circuit is the movement of oxygen depleted blood to the lungs to pick up oxygen and unload carbon dioxide.
The amount of oxygen in the air does not get depleted because it is constantly being replenished through processes such as photosynthesis by plants and algae. These organisms convert carbon dioxide into oxygen, helping to maintain a relatively stable level of oxygen in the atmosphere.
Capillaries carry Oxygenated (oxygen rich) blood and De-oxygenated (oxygen depleted) blood.
Water can be depleted of it's oxygen by a number of different ways. Short of putting the water in a vacuum and "sucking" the dissolved oxygen out, oxygen-breathing organisms such as fish take oxygen from the water through respiration, for example. It is unlikely a large body of water to become completely deoxygenated due to the presence of photosynthetic aquatic organisms (plants) and the fact that oxygen is also dissolved in the water at the water's surface.
A candle will burn for a very short time without oxygen as it needs oxygen to sustain the combustion process. Once the oxygen supply is depleted, the flame will extinguish quickly.
