when certain proteins interact randomly and produce molecules that make the body  stiffer. They also interfere with metabolism. Third type of cellular theory proposes that free radicals which are highly reactive  chemicals produce randomly during normal cell metabolism , cause cell damage. Changes to the bodies build as we age Amount of muscle changes but strength and durability stay the same Loss of bone mass  Changes in vision with age Several differences occur, decrease in the amount of light passing through the eye and  in the ability to adjust changes in illumination Changes in hearing Decline in ability to hear high pitch tones Exposure to noise speeds up and exacerbates hearing loss Reduction in ability to have satisfactory  Changes in touch and balance Changes in sensitivity to touch, temperature, and pain are complex and not understood;  age-related trends are unclear in most cases Dizziness and vertigo are common in older adults and increase with age as do falls. Age changes in the cardio vascular system Fat deposits in and around the heart and inside arteries are a normal part of aging. Most  important is stiffening of the walls of arteries Men have higher rate of cardiovascular disease than women. Structural and functional changes in the respiratory system with age Decline in maximum amount of air we can intake  Reproductive changes in women Transition from childbearing years to the cessation of ovulation is called the climacteric;  menopause is the point at which the ovaries stop releasing eggs.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
