Explanation:
Detailed explanation-1: -Angina is a temporary chest pain or discomfort that happens when your heart doesn’t get enough blood and oxygen. It is a symptom of an underlying heart condition, usually coronary heart disease.
Detailed explanation-2: -The sinus node generates an electrical stimulus regularly, 60 to 100 times per minute under normal conditions. The atria are then activated. The electrical stimulus travels down through the conduction pathways and causes the heart’s ventricles to contract and pump out blood.
Detailed explanation-3: -Thrombocytes, or platelets, are not complete cells, but are small fragments of very large cells called megakaryocytes. Megakaryocytes develop from hemocytoblasts in the red bone marrow.
