What percent of patients improved? 60% how much simple interes...

mechanical digestion Part of digestion that uses movement and muscles to break down food into smaller pieces digestion breaking down nutrients into small, soluble molecules that can be absorbed into the blood chemical digestion the digestion process in which enzymes are used to break foods into their smaller chemical buiding blocks occurs via hydrolysis hydrolysis A chemical process that lyses, or splits, molecules by the addition of water; an essential process in digestion. enzymes mol...

Cell smallest living unit and the basic unit of function and structure for all living things. Nucleus contains genetic information or DNA, controls the activities of the cell. DNA - Deoxyribonucleic Acid - genetic information. Plasma or Cell Membrane Semipermeable membrane that separates the contents of the cell from the surrounding fluids (interstitial fluid). Interstitial Fluid contains substances such as aminoacids, sugars, fatty acids, hormones, neurotransmitters and salts. Selectivel...
