Definition: The amount of a substance in a solution, usually measured in osmoles per liter, which indicates how concentrated the solution is.

Example: The osmolarity of the saline solution was carefully measured to ensure proper hydration.

Definition: A unit used to measure the amount of a substance that affects the movement of water across a membrane in a solution.

Example: The doctor ordered a solution with a specific number of osmoles to ensure proper hydration for the patient.

Definition: A device used to measure the pressure created by the movement of water through a semipermeable membrane due to osmosis.

Example: The scientist used an osmometer to determine the osmotic pressure of the solution.

Definition: The process of measuring the pressure that is created when a solvent moves through a semipermeable membrane due to differences in concentration of solutes.

Example: Osmometry is used in laboratories to determine the osmotic pressure of various solutions.

Definition: The process by which living organisms maintain a stable balance of water and salts in their bodies to ensure proper functioning.

Example: Fish use osmoregulation to control the salt concentration in their bodies, allowing them to survive in different water environments.

Definition: Relating to the process by which organisms regulate the balance of water and salts in their bodies.

Example: Fish have osmoregulatory mechanisms that help them maintain the right balance of salt in their bodies.

Definition: Related to the process by which water or other substances pass through a membrane from an area of lower concentration to an area of higher concentration.

Example: The osmotic pressure in the cell helps maintain its shape and function.

Definition: In a way that relates to the process of osmosis, where substances move through a membrane from an area of lower concentration to an area of higher concentration.

Example: The cells absorbed water osmotically, allowing them to maintain their shape and function.

Definition: A structure or framework that supports something, like a building or a statue.

Example: The architect designed the ossature to ensure the building would be stable and strong.

Definition: Made of or related to bone; having a bony structure.

Example: The osseous tissue provides support and structure to the skeleton.
