Definition: A thin layer of flat cells that forms the inner lining of blood vessels, lymph vessels, and certain body cavities.

Example: The endothelium plays a crucial role in regulating blood flow and maintaining vascular health.

Definition: A type of animal that can produce its own heat to keep its body temperature stable, usually warmer than the environment around it.

Example: Birds and mammals are examples of endotherms that can regulate their body temperature.

Definition: Relating to organisms that produce their own heat to keep their body temperature higher than the environment, or to processes that absorb heat.

Example: Endothermic animals, like mammals, can maintain a stable body temperature regardless of the outside conditions.

Definition: The ability of an organism to generate and control its own body heat through metabolic processes, allowing it to maintain a stable internal temperature regardless of the environment.

Example: Birds and mammals are examples of animals that exhibit endothermy, allowing them to thrive in various climates.

Definition: Relating to or caused by a type of toxin that is found inside certain bacteria and can cause harmful effects when released.

Example: The researchers studied the endotoxic effects of the bacteria on the immune system.

Definition: A harmful substance made by some bacteria that is released when the bacteria die.

Example: The endotoxin released by the bacteria caused a severe reaction in the patient.

Definition: Relating to or occurring within the trachea, which is the tube that carries air to the lungs.

Example: The doctor inserted an endotracheal tube to help the patient breathe during surgery.

Definition: Relating to obtaining nourishment from within another organism or penetrating into the associated root and spreading between the cells.

Example: Some plants are endotrophic, relying on their host for nutrients.

Definition: Describing organisms that live inside another living animal, often as parasites.

Example: The endozoic bacteria can affect the health of their host.

Definition: A special part of a muscle fiber that connects to a nerve at a point where they meet, allowing signals to pass between them.

Example: The endplate is crucial for muscle contraction as it transmits signals from the nerve to the muscle.
