Detailed explanation-1: -Heart muscle makes up one of the earliest functioning embryonic organs that continues to contract and beat from development throughout a lifetime. Supplied by a complex system of coronary vasculature, cardiac lymphatics, and autonomic innervation, cardiomyocytes line the thickest layer of every chamber of the heart.

Detailed explanation-2: -Your heart is a vital organ. It is a muscle that pumps blood to all parts of your body. The blood pumped by your heart provides your body with the oxygen and nutrients it needs to function. Your heart is about the size of a clenched fist, and weighs between 300 and 450 g.

Detailed explanation-3: -Your heart is actually a muscular organ. An organ is a group of tissues that work together to perform a specific function. In the case of your heart, this function is pumping blood throughout your body. Additionally, the heart is largely made up of a type of muscle tissue called cardiac muscle.

Detailed explanation-4: -Overview. The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.

Detailed explanation-5: -The heart is a fist-sized organ that pumps blood throughout your body. It’s the primary organ of your circulatory system. Your heart contains four main sections (chambers) made of muscle and powered by electrical impulses.
