Iron and B12, mostly. Oxygen binds to iron which makes blood red, like rust. B12 is required to make it all work. Also Google or Wiki the Kreb's cycle (oxygen based metabolism) for related vitamins and minerals after the oxygen is delivered.
Sometimes during labor, the baby isn't getting enough oxygen, so the doctors give the mother an oxygen mask to increase the amount in the blood to get it to the baby.
Iron.
It decreases due to the increase in carbon dioxide in the blood. This causes more oxygen to be uploaded to the tissues
There is a slight increase of carbon dioxide in the blood. Hicups are your body's way of getting more oxygen into the blood.
Hypoxia means having low oxygen, so the more red blood cells, the more oxygen can be carried by the blood.
oxygen
it combines with haemoglobin forming the carboxyhaemoglbin thus which is alarge complex and affinity to the oxygen is lost leading to increase in blood pressure.
When someone is tired, he or she yawns to increase the oxygen content in the blood. The blood is then carried to the brain which increases alertness or in other words wakes you up.Fun Fact! All animals can yawn!When sleepy or tired, you yawn to increase the oxygen content in the blood. The blood is then carried to the brain for increased alertness.
a capillary is our body's smallest form of blood vessel the more capillary's at the muscles, the more oxygen the muscles can use an increase in capillarisation means that there is an increase in blood vessels and subsequently an increase in the opportunity for blood (and oxygen) to be transported to and used by the muscles a decrease in capillarisation means that there is a decrease in poo vessels and subsequently a decrease in the opportunity for blood (and oxygen) to be transported to and used by the muscles aerobic or endurance training does well to bring about an increase in capillarisation, meaning that muscles can perform for longer peroids of time as they are able to use more oxygen for contraction
too little oxygen
increase red blood cell orincrease the oxygen-carrying capacity of the blood for improved athletic endurance.
We know that our blood has a pigment called Haemoglobin,which gives characteristic red colour to blood.A haemoglobin molecule carries a maximum of 4 oxygen molecules,and is called 100% saturated when it does so.So,breathing pure oxygen doesn't increase the transport of oxygen.
