Epithelial, Connective, Muscular, and Nervous
Epithelial tissue covers inside and outside body surfaces, lines the cavities, tube, ducts and blood vessels, and is the main tissue of glands. Because here is no vascular supply, it absorbs nutrients from the connective tissue underneath. The tightly packed cells make a barrier that offers protection. Because the epithelial tissue is innervated by nerves, it acts as a sensory perception
The extracellular matrix in connective tissue allows it to bear weight, take abuse, and stretch. Connective tissue has a good blood supply and can therefore transport substances. Bone is considered connective tissue and provides framework and protection. Adipose is also connective tissue; it insulates and stores fat.
There are three types of muscular tissue: skeletal, smooth, and cardiac. The skeletal muscle are the large body muscles. They attach to the bone which allows for movement. Smooth muscle lines the organ walls and the blood vessel walls. Because of this, they can move blood, food, and waste through the body's organs. The cardiac muscle lies around the heart. Its location allows for heart beat contractions.
Nervous tissue is associated with the brain, spinal cord, and nerves. It lies all through the body, sending electric signals that allow the body to respond to its environment.
The location of muscle tissue is important in its function because it allows us to move. The muscles attach to the bone, and contracts, expands, stretches as we wish. The cardiac muscles are responsible for allowing our heart to beat. Without it, blood could not be pumped in and out of our heart. Muscle tissue is essential for human life.
