Pure O2 would be best but, you would have to be able to force it with a ventilator or such.
Breathing is the simple answer. Respiration is also an answer but respiration includes oxygen going into the bloff and throughout the body and Carbon Dioxide going back to the lungs and being exhaled.
Respiration is breathing in and absorbing oxygen, and breathing out carbon dioxide.
Pulmonary artery 1. No oxygen 2. A lot of carbon dioxide Pulmonary vein 1. Lots of oxygen 2. No carbon dioxide
When you have pulmonary disease, you may fail to give out carbon dioxide. So the percentage of carbon dioxide increase in your blood. That is the indicator of the severity of the pulmonary disease.
Pulmonary function
The systemic circulation brings oxygen-filled blood to the body tissues, and returns carbon-dioxide filled blood to the heart. The pulmonary circulation brings carbon-dioxide filled blood to the lungs.
The blood cells carry carbon dioxide to the lungs which, through the mechanism of breathing, gaseous exchange takes place with the carbon dioxide leaving the body while someone breathes out. When they breathe in again, the blood cells in the pulmonary capillaries get loaded with oxygen and the new oxygen rich blood goes to the heart to be sent around the body.
Pulmonary system- contains tissues and organs specialized for taking in oxygen and removing carbon dioxide from our bodies and for exchanging oxygen and carbon dioxide.
an excretion is an example of breathing out Co2
There is carbon dioxide in the atmosphere. You have been breathing it in all your life.
Only a proportion of the air exhaled is carbon dioxide there is plenty of Oxygen there to do what is required under normal circumstances. People don't use all of the oxygen they breath in, a % of it is blown right back out of the body again.
respitatory, taking oxygen in...and breathing carbon dioxide out. carbon dioxide=Co2 and oxygen = O
