Organ Systems/Organization
The system that provides locomotion and movement to the body.
What is the muscular system?
Remaining in a steady state, referring to the maintenance of internal balance. Maintaining a relatively constant internal environment in fluctuating external environments.
What is homeostasis?
An organism that obtain their chemical energy from an outside source (food).
What is a heterotroph?
Type of tissue that functions in the reception, processing, and transmission of information through impulses.
What is nervous tissue?
Organisms that are warmed mostly by heat generated internally by the metabolism; i.e humans and other mammals.
What is endothermic?
Disposal of metabolic wastes; regulation of osmotic balance of blood.
What is the excretory system?
A stimulus that amplifies a stimulus rather than reducing it.
What is positive feedback?
The overall flow and transformation of energy in an animal.
What is bioenergetics?
The type of tissue that holds many other tissues and organs together and in place; contains fibroblasts and macrophages.
What is connective tissue?
A major thermoregulatory adaptation in mammals and birds which reduces the flow of heat between an animal's body and its environment.
What is insulation?
Skin and its derivatives (hair, claws, skin glands).
What is the integumentary system?
An animal that allows its internal condition to change in accordance with external changes in the variable.
What is a conformer?
The minimum metabolic rate required for basic functions (like cell maintenance) of a nongrowing endotherm that is at rest, has an empty stomach, and is not experiencing stress.
What is basal metabolic rate?
What is skeletal muscle tissue?
The sensors for thermoregulation are located here.
What is the hypothalamus?
Fills the spaces between cells to reduce friction and exchange materials like nutrients and wastes.
What is interstitial fluid?
A set of physiological changes that occur roughly every 24 hours controlled by certain cyclic alterations in metabolism.
What is a circadian rhythm?
An adapted physiological state of decreased activity and metabolism that enables animals to save energy while avoiding difficult and dangerous conditions.
What is torpor?
Polar side of the epithelia that faces the lumen or outside of the organ.
Maintaining rate of heat gain that equals rate of heat loss.
What is the essence of thermoregulation?
The cavity in which the pleural cavity belongs.
What is the thoracic cavity?
The gradual process by which an animal adjusts to changes in its external environment.
What is acclimatization?
Transfer of heat between fluids that are flowing in opposite directions.
What is countercurrent exchange?
Single layer of ciliated cells that form a mucous membrane that sweep the film of mucus along the respiratory tract.
The transfer of heat by the movement of air or liquid past a surface, as when a breeze contributes heat loss from the skin.
What is convection?
