Okay, so a group of cells make a tissue.
A group of tissues make a organ.
A group of organs make an organ system.
A group of organ systems make an organism.
That's the easiest way to put it. I know what you're thinking, "But I said "muscle tissues"!". Well, it's all the same thing. Tissues are tissues, and whether it's a muscle tissue or a... I really don't know tissue, it's considered a tissue, so to make it long story short, a group of cells make a tissue. Your welcome.
The kind of tissue that makes up contracting organs is muscle tissue: cardiac, smooth and skeletal muscle.
muscle tissue
Cardiac muscle tissue is the specific muscle tissue that makes up the bulk of the heart. It is different than either skeletal or smooth muscle.
The tissue that makes up organs that are able to contract or shorten is known as muscle tissue. Muscle tissue is composed of muscle cells that contain protein filaments that slide past each other, causing the muscle to contract and generate force. There are three types of muscle tissue: skeletal, cardiac, and smooth.
skeletal muscle
Muscle or myeloid tissue.

Myocardium.
Cardiac muscle makes up the bulk of the heart. That tissue is made of cardiomyocytes or muscle cells.
