Bond [772]

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.

Organelles → cells → tissues → organs → organ systems → organisms → populations →communities → ecosystem → biosphere.

It is clear that tissue is organization level that exists between cells and organs.

When similar cells are assembled together to perform specific function, the assembly or this organization is said to be the tissue.

There can be different types of tissues such as muscle tissue, nerve tissue et cetera.

Similarly, tissues arrange themselves to carry out specific function in the form of organ.

For example, heart is made up of cardiac tissue.
