Why is your heart more complex than your circulatory
No.
The "R" is the greatest deflection from the baseline on the ECG. The R is part of the QRS complex. This complex represents ventricular depolarization in the heart.
There is no evidence that the heart has developed and changed as organisms have become more complex over time. Scientists do believe that the human heart is a product of evolution and has spent millions of years perfecting itself in order to keep humans alive.
The structure of the heart is very complex. Cardiac myocytes and intercalated discs follow the function of cardiac muscle tissue and the heart make up part of this very complex system

A complex salt is the salt of one or more complex ions, the complex part can be cationic or anionic or both such as Ca3[Co(Cl)6]2 the complex part behaves as an anion [Co(NH3)6]Cl3 the complex part behaves as a cation [Co(NH3)6][Co(Cl)6] the both of the anionic and cationic parts of the are formed by complex ions
The heart functions as a whole organ if a piece is missing then it wouldn't be able to function. Think of a mouse trap, it has about 5 separate parts if one is part is missing then the mouse trap is useless. A heart is more complex than a mouse trap and needs all of it's parts to function properly
Pelicans and humans require a more complex heart to efficiently support their active lifestyles and meet the high metabolic demands of their bodies. A four-chambered heart allows for the separation of oxygenated and deoxygenated blood, ensuring that tissues receive a constant supply of oxygen-rich blood. This efficiency is crucial for activities such as flying in pelicans and maintaining energy levels in humans. Additionally, a more complex heart facilitates better regulation of blood flow and pressure, which is essential for both species' survival and adaptation to their environments.
The cardiac cycle refers to a complete heartbeat, including the systole and diastole. The QRS complex occurs during the depolarization of the right and left ventricles of the human heart.
The components of the circulatory system include the heart, blood, and blood vessels. The pulmonary circulation is also part of this complex system.
