Verified step by step guidance

Step 1: Understand the components of blood. Blood is composed of two main parts: plasma (the liquid portion) and formed elements (the cellular components). Plasma contains water, proteins like albumin, antibodies, and other dissolved substances.

Step 2: Define formed elements. Formed elements refer to the cellular components of blood, which include erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets). These are distinct from plasma proteins like albumin and antibodies.

Step 3: Analyze the options provided. Albumin and antibodies are proteins found in the plasma, not cellular components. Plasma itself is the liquid portion of blood and does not qualify as a formed element.

Step 4: Identify erythrocytes. Erythrocytes, or red blood cells, are a type of formed element responsible for transporting oxygen and carbon dioxide throughout the body.

Step 5: Conclude that erythrocytes are the correct answer because they are classified as a formed element of blood, unlike albumin, antibodies, or plasma.
