The outer surfaces of the organs and body cavities are covered by this double layered membrane called what? {Ans: serosa}cholesterol {Ans: Cholesterol is a lipid that is very hydrophobic and has one polar hydroxyl group. It joins with phopholipids and mixes in with the tails to prevent solidification during low temperatures. It also stabilizes the phospholipd head with the hydroxyl group by restricting movement in higher temperatures.}Away from the head end or toward the lower part of a structure of the body is what direction? {Ans: Inferior}The abdominopelvic region is divided into what four quadrants? {Ans: right upper, left upper, right lower, and left lower}diffusion {Ans: Diffusion is when molecules move from an area of higher concentration to an area of lower concentration to achieve equilibrium with the two sides of a membrane. (small molecules such as gases, water, and glycerol as well as lipid-soluble molecules such as hydrocarbons) Facilitated diffusion is used for a lipid-insoluble molecule and happens by carrier proteins binding temporarily to the molecule and releasing it to the other side. (lipid-insoluble (polar) molecules such as sugars and amino acids)}What are microfilaments? {Ans: Microfilaments are solid fibers that create movement.}Name the
