respiration

The respiratory system has two forms of respiration: external respiration, which is the exchanging of gases between the lungs and the bloodstream, and internal respiration, which is the exchanging of gases between the bloodstream and the body tissues. Inside the lungs, oxygen is exchanged for carbon dioxide waste. Oxygen then binds to the hemoglobin component of the blood and is pumped into the bloodstream. The bloodstream then delivers oxygen to cells throughout the body. When the blood cells become deoxygenated, they then assist with transporting carbon dioxide back to the lungs to be released. When there is a lack of red blood cells in the body, our body isn’t able to transfer oxygen efficiently leading to many symptoms. When the brain doesn’t receive sufficient amount of oxygen, you may develop nausea, which our patient has demonstrated. Also our body cells need oxygen to produce energy. However, due to the lack of oxygen circulating in our patient’s body, their body cells are not able to produce a lot of energy, thus resulting in their symptoms of fatigue and weakness.
