Final answer:
Blood leaving the left ventricle has a high oxygen concentration and a lower concentration of carbon dioxide due to gas exchange in the lungs.
Step-by-step explanation:
A chemical analysis of blood leaving the left ventricle of the heart would reveal that it has a high concentration of oxygen (∂06), along with a lower concentration of carbon dioxide (∂CO). This reflects the blood's role in transporting oxygen from the lungs to the tissues and carbon dioxide from the tissues back to the lungs. After passing through the lungs, oxygen binds to hemoglobin in red blood cells, which greatly increases the oxygen content of the blood. Conversely, carbon dioxide is present in blood primarily in the form of bicarbonate, with a smaller amount dissolved in plasma.
