When sarcomeres shorten, the muscle fiber SHORTENS.
Mechanism :
Sacromeres are used to construct the myofibrils, which are a part of the skeletal muscles of animals. They use the sliding filament model to carry out the muscle contraction and relaxation.
To create movement, The cross-bridge between actin and the myosin heads causes the sacromere to shorten. Muscle fibers contract as a result of this shortening of the sacromere, which has the overall effect of shortening the fibers.

Hydrophilic (water-loving) or could be called water, it mean attracting water molecules as close as possible, the phospholipid is made up of a head that is polar, and a tail that is non polar or in another words called “hydrophobic” , this means that the head of the phospholipid is attracted to water molecules ( this helps you understand the structure of cell membrane formation). Steriod, a class of lipids, some hormones like cholesterol are made up of steroids. They maintain fluidity of cell membrane. Example: oestrogens
Answer:
The muscles of the muscular system work with the bones of the skeletal system.
Explanation: The musculoskeletal system is what enables movement.

Answer:
Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium
Explanation:
these r parts of the heart btw
