What is contained in the cranial cavity? → Heart and lungs
What is facilitated diffusion and how does it work? → movement of molecules from an area of greater concentration to an area of lesser concentration along the concentration gradient. Very slow process. FOR MOLECULES
(Example: exchange of gases in lungs or body tissues)
What is contained in the abdominal cavity? → Spinal vertebre
What is mitosis? → process of cell division that results in the formation of gametes which are egg and sperm cells.
