- P-wave
- Q-wave
- T-wave
- ORS complex
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
A normal electrocardiogram or ECG comprises of a $P$ wave, a $QRS$ wave complex and a $T$ wave in which $P$ wave represents depolarisation of the atria, $QRS$ wave complex represents depolarisation of the ventricles and $T$ wave represents ventricular repolarisation.

Circulatory Pathways
Virtually every cell, tissue, organ, and system in the body is impacted by the circulatory system.
- Digestive - Absorbs nutrients and water; delivers nutrients (except most lipids) to liver for processing by hepactic portal vein; provides nutrients essential for hematopoiesis and building hemoglobin.
- Endocrine - Delivers hormones: atrial natriuretic hormone (peptide) secreted by the heart atrial cells to help regulate blood volumes and pressures; epinephrine, ANH, angiotensin II, ADH, and thyroxine to help regulate blood pressure; estrogen to promote vascular health in women and men.
- Integumentary - Carries clotting factors, platelets, and white blood cells for homeostatis, fighting infection, and reparing damage; regulates temperature by controlling blood flow to the surface, where heat can be dissipated; provides some coloration of integument; acts as a blood reservoir.
- Muscular - Provides nutrients and oxygen for contraction; removes lactic acid and distributes heat generated by contraction; muscular pumps aid in venous return; exercise contributes to cardiovascular health and helps to prevent atherosclerosis.
