It is a result of intense exercise
The muscle is in spasm
The circulatory system consists of the heart, blood and blood vessels working together to supply oxygen to the working muscles and removing unwanted carbon dioxide.
The upper chambers of the heart are called the ventricles.
The right side of the heart is thicker as it transports oxygenated blood to the working muscles of the body.
The pulmonary circuit involves taking deoxygenated blood to the lungs and returning oxygenated blood to the heart.
