Midterm Examination

It is the liquid portion of blood; our red and white blood cells and platelets are suspended in plasma as they move throughout our bodies.

• Plasma

• Platelets

• White Blood Cells

• Red Blood Cells

This are chemical structures composed of proteins that receive and transduce signals that may integrated into biological systems.

• Structural Proteins

• Transport Proteins

• Receptors Proteins

• Regulatory Proteins

Choose in the following statement which correspond the correct answer.

I. Red blood cells survive only about 9 days in the bloodstream and are constantly being replaced by new platelets made by the bone marrow.

II. Each day, the body makes new RBCs to replace those that die or are lost from the body.

III. Serum is the fluid and solute component of blood which does not play a role in clotting. It may be defined as blood plasma without the clotting factors, or as blood with all cells and clotting factors removed.

IV.      The white blood cell count in someone with an infection often is higher than usual because more RBCs are being made or are entering the bloodstream to battle the infection.

• II, III

• II, III, IV
