Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, the others being skeletal muscle and smooth muscle.It is an involuntary, striated muscle that constitutes the main tissue of the wall of the heart.
Intercalated discs are complex structures that connect adjacent cardiac muscle cells.The three types of cell junction recognised as making up an intercalated disc are desmosomes, fascia adherens junctions, and gap junctions.
The heart is a muscular organ found in humans and other animals.This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2]
A syncytium (/ s ɪ n ˈ s ɪ ʃ i ə m /; pl.: syncytia; from Greek: σύν syn "together" and κύτος kytos "box, i.e. cell") or symplasm is a multinucleate cell that can result from multiple cell fusions of uninuclear cells (i.e., cells with a single nucleus), in contrast to a coenocyte, which can result from multiple nuclear divisions without accompanying cytokinesis.

Smooth muscle is involuntary and found in parts of the body where it conveys action without conscious intent. The majority of this type of muscle tissue is found in the digestive and urinary systems where it acts by propelling forward food, chyme, and feces in the former and urine in the latter.
Myocardial disarray, also known as myocyte disarray, is a term to describe the loss of the normal parallel alignment of myocytes [1] (the muscle cells of the heart).Instead, the myocytes usually form circles around foci of connective tissue.
The lungs are the primary organs of the respiratory system in many animals, including humans. In mammals and most other tetrapods, two lungs are located near the backbone on either side of the heart.
A medical monitoring device displaying a normal human heart rate. Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute (beats per minute, or bpm).
