consciousness and they are located in the walls of hollow internal organs such as blood vessels‚ uterus and bladder. They facilitate or retard the transportation of fluid. * Cardiac muscle: It is located in the walls of the heart and its part of the autonomic nervous system too‚ meaning they contract involuntarily. The cardiac muscle cell has one central nucleus like smooth muscle‚ but its striated like skeletal. It is rectangular in shape. The contraction is involuntary‚ strong and rhythmical.

Skeletal System Skeletal system is the biological system providing support in living organisms. Skin‚ muscle and bones allow movement. Skin - pliable covering. Muscles do actual moving. Bones give anchor to move against. The skeleton functions not only as the support for the body but also in haematopoiesis‚ the manufacture of blood cells that takes place in bone marrow. This is why people who have cancer of the bone marrow almost always die. It is also necessary for protection of vital organs

P4 Explain two theories of aging Disengagement Theory This is the first formal theory of aging and it was brought forward by Elaine Cumming and William Henry in 1961‚ and they looked at how society views older people. During their research they found that older people disengaged from society. They argue that older personnel withdraw from society‚ for example they stop working/retirement‚ they stop socialising‚ they feel that they are no longer needed by wider society‚ for example they younger generation

Muscles are responsible for all conscious and unconscious movement. It is how we move and react to an environment. There are three types of muscles in the body include the skeletal muscle‚ smooth muscle‚ and the cardiac muscle. Whether you are running‚ walking‚ breathing‚ eating‚ sleeping‚ or typing it all involves some sort of muscle action. Muscle cells that shape‚ form‚ and outline the whole human skeleton is called a muscle fibers. There are two types of muscle fibers: Type I (slow-twitching

skeletal muscle‚ cardiac muscle‚ and smooth muscle. The skeletal muscle’s main function is to move the bones of the skeleton. This muscle is voluntary and is also striated‚ meaning that it is striped‚ which is due to the muscle fibers that are combined into parallel fibers. Some of these muscles can be controlled unknowningly. For example‚ the diaphragm of the human body continues to alternately contract and relax while we are asleep‚ allowing our lungs to expand to breathe. The cardiac muscle tissue

tissue like the material in a rubber band. Thousands or tens of thousands of small fibers make up all or each muscle in our body. There are different muscles‚ fibers‚ and contractions. Three different types of muscles include cardiac‚ smooth‚ and skeletal. Cardiac muscle cells are located in by the heart in the walls‚ look striated‚ and are under involuntary control. Smooth muscle fibers are located in walls of hollow organs‚

1. Muscoloskeletal system response to acute exercise12 1.1. Increased blood supply3 As you exercise‚ blood vessels in muscles dilate and blood flow is greater As exercise begins‚ blood from organs Is diverted to muscles When you begin to exercise‚ a diversion happens and blood that would have gone to the stomach or kidneys goes instead to the muscles ->Vascular Shunt The way that happens shows how bod’s processes can sometimes override another 1.2.
