Blood is supplied to the muscular wall of the left atrium by the left coronary artery
Blood is considered a connective tissue that remains flowing continuously in the body and carries oxygen, nutrients, and hormones from one place to another place in the body.
It is pumped into the body equally through the heart which consists of four chambers and several valves and arteries which work in a coordinated manner to collect deoxygenated blood collected from the body and replace oxygen in it and pump it into the other parts of the body.
The left coronary artery (LCA), also known as the left main coronary artery (LMCA) arises from the aorta above the left cusp of the aortic valve and transports the blood to the left side of the heart muscle.

<span>Around 2.4 billion years ago, the first photosynthetic organisms appeared and used inorganic matter like carbon dioxide and water to produce glucose, with oxygen released in the atmosphere. Because of this, oxygen levels rose; this is called the <em>Great Oxygenation Event</em><span><em>.</em> Through time, photosynthetic organisms evolved to live in land (now as plants). As concentrations of oxygen in the atmosphere became higher, marine animals evolved to utilize oxygen readily available from the atmosphere (rather dissolved in water) hence the evolution of marine animals to land animals capable of respiration in land. </span></span>
