Which of the following is true of blood?

Question

Quizplus · Accepted Answer

The liquid portion of blood, known as plasma, contains ions (like sodium and potassium), nutrients (like glucose and amino acids), and hormones (like insulin and estrogen).

Answer: None of the above
 Both options B and C are incorrect. While some cells in blood (like white blood cells) do play a role in fighting infections, not all cells serve this function. Additionally, red blood cells do not have any nuclei at all. Option D is also incorrect, as both the cellular and liquid components of blood play a role in gas exchange (with red blood cells carrying oxygen and carbon dioxide, and plasma helping to transport other gases like nitrogen and carbon monoxide).
