The circulatory system = the heart + the blood vessels. The heart is a muscle, but the muscle fibers are slightly different to skeletal muscle. Arteries has a thin layer of muscle cells that surround them so that they can constrict or expand the blood vessels in order to regulate blood pressure.
The heart, which pumps the blood around, is a muscle itself.
The heart is an organ, not a muscle. However, it's the cardiac muscles that allow the heart to perform its function of pumping blood around the body.
the main parts are the heart, blood, blood vessels, and lungs
Heart and skin.
Cells Make Tissues, Tissues Make Organs. A muscle is a Tissue because It is a lot of tissue, but not enough to form Organs or a Organ.
The kind of tissue that makes up contracting organs is muscle tissue: cardiac, smooth and skeletal muscle.
Muscle tissue makes up organs that are able to contract and shorten.
