Blood returning to the heart from the body has a higher percentage of carbon dioxide within it. Which of the following statements explains this phenomenon?
The blood has produced more carbon dioxide as it flows around the body.
The blood has picked up the carbon dioxide from cells that have been performing respiration.
The body has turned the blood cells into carbon dioxide.
The oxygen in the blood has turned into carbon dioxide.
When blood returns from the lungs to the heart, it contains more oxygen than it did when it left. Which of the following statements explains why this is so?
The blood returning from the lungs has a low concentration of carbon dioxide.
The haemoglobin in the red blood cells binds to the oxygen.
The carbon dioxide is dissolved in the plasma.
The blood contains a higher concentration of oxygen than the air when it arrives back at the lungs.
