What is the organ system composed of tissue that can contaract and relax?
The organ system composed of tissue that can contract and relax is the muscular system. It includes three types of muscle tissue: skeletal, cardiac, and smooth. Skeletal muscles facilitate voluntary movements, cardiac muscle pumps blood in the heart, and smooth muscles control involuntary movements in organs. Together, these tissues enable a wide range of bodily functions.
What focuses light and images onto the retina?
The thing that focuses the retina is the pupil.the light rays pass through the cornea into the pupil while passing through a cavity which contains a jelly-like liquid called aqueous humor.then the rays pass through the pupil to the lens.the light rays are converged by the lens and the aqueous humor to an extent that it focuses the rays of light on the retina(yellow spot).
