Answer: The skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals. The skeletal system is also called the musculoskeletal system.
Explanation:
<span>A human body is composed of muscles. Without it, the human body cannot function and will die. </span>
There are three types of muscle tissues: Skeletal muscle, Cardiac muscle, and Smooth muscle.
The skeletal muscle aids in the movement of the human skeleton. The 600 skeletal muscles make up 40 % of our body weight and are reliant on the signals released by our nervous system to start moving.
<span>Cardiac muscles are those muscles which encloses our hearts. They are involuntary muscles which pumps blood throughout our bodies by creating steady and rythmic pulsing. They also make our heart contract by producing electrical impulses. </span>
<span>Smooth muscles are found in the walls of blood vessels, respiratory passageways, and hollow organs. Its contracting movement is wavelike and it helps in the transfer of food through our stomachs or urine through our bladder. </span>
<span>These muscles responds to nerve impulses and other stimuli.</span>
After collecting evidence that concludes that the current plan to manage the Alaska crab fishery makes it only a potentially renewable resource, m<span>ore research should be done into the reproductive behaviors of the different species. This solution tries to solve the problem at its roots. That is, if the management determines why there are fewer species based on their reproductive behaviors, certain changes can be made in order to create an environment that will enhance their reproduction. </span>
The answer is the salivary gland.
Saliva is secreted through the surface of the tongue.<span />
