Which term from the list denotes the overall makeup of blood?

Explanation:
The key idea is recognizing what describes all the components that make up blood. Blood composition refers to the entire set of constituents in blood—plasma with its proteins, nutrients, and electrolytes, plus the formed elements like erythrocytes, leukocytes, and platelets, along with their internal components such as hemoglobin. Hemoglobin is just the oxygen-carrying protein inside red blood cells, so it’s only one part of the whole. Normal blood pH is a property describing acidity, not the makeup of blood. Erythrocytes are a major formed element but do not represent the complete composition. Therefore, the broad term that denotes the overall makeup of blood is blood composition.
