Definition: Relating to the concentration of solute particles in a solution, often used in the context of bodily fluids.

Example: The osmolar level of the blood is important for maintaining proper hydration.

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: 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: To spread or cause to spread gradually through a medium, similar to how substances move through a semi-permeable membrane.

Example: The scientist observed how the dye would osmose through the water over time.

Definition: A process where a liquid moves through a barrier to balance concentrations on both sides, or a gradual way of learning or absorbing information without direct effort.

Example: She learned the language by osmosis while living in the country.

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 tiny bone, particularly one of the three bones found in the middle ear that help with hearing.

Example: The ossicle in the ear plays a crucial role in transmitting sound vibrations.
