Formed elements in the blood _______.

Formed elements in the blood _______.

• A. include platelets and whole cells that slide past one another
• B. are plasma proteins
• C. are dissolved gases
• D. are antibodies

Answer: (A)

Formed elements are the cellular portion of blood—the actual cells or fragments derived from cells that circulate in the plasma. This includes red blood cells, white blood cells, and platelets. Platelets are small cytoplasmic fragments that help with clotting, while red and white cells carry oxygen and coordinate immune responses, respectively. These elements are suspended in plasma and move past one another as blood flows. The other components listed belong to plasma, not the formed elements. Plasma proteins, including antibodies, are dissolved in plasma. Dissolved gases are carried in the plasma as well. Antibodies are a type of plasma protein produced by immune cells, not cellular fragments or whole cells.
