the four structures that compose the conduction system of the heart are the
sa node, av node, av bundle, and purkinje fibers.
sa node, av node, av bundle, and chordae tendinae.
av node, av bundle, purkinje fibers, and chordae tendinae.
sa node, av node, av bundle, and papillary muscles.

Explanation:

• Question 13: Granulocytes are a type of white blood cell with granules in their cytoplasm. Neutrophils, eosinophils, and basophils are granulocytes. Lymphocytes are agranulocytes (white blood cells without visible granules).
• Question 14: Formed elements in blood include red blood cells, white blood cells, and platelets. Plasma is the liquid part of blood, not a formed element.
• Question 15: The conduction system of the heart consists of the sino - atrial (SA) node, atrioventricular (AV) node, AV bundle (bundle of His), and Purkinje fibers. Chordae tendineae and papillary muscles are related to heart valve function, not the conduction system.

Answer:

• Question 13: lymphocytes.
• Question 14: plasma.
• Question 15: SA node, AV node, AV bundle, and Purkinje fibers.
