Coagulation - procoagulants. The third step, coagulation or blood clotting, reinforces the platelet plug with fibrin threads that act as a molecular glue for the aggregated platelets. The resulting blood clot (fibrin mesh) is quite effective in sealing larger breaks in a blood vessel. Blood is transformed from a liquid to a gel in a multistep process that involves a series of substances called clotting factors, or procoagulants.
Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell.Muscles function to produce force and motion. Smooth muscle or involuntary muscle is found within the walls of organs and structures such as the esophagus, stomach, intestines, bronchi, uterus, urethra, bladder, blood vessels, and the arrector pili in the skin (in which it controls erection of body hair).
The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a personâs body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.Muscle tissue is also found inside of the heart, digestive organs, and blood vessels. In these organs, muscles serve to move substances throughout the body....unction of Muscle Tissue. The main function of the muscular system is movement. Muscles are the only tissue in the body that has the ability to contract and therefore move the other parts of the body.
