Thermoregulation
100

The system that provides locomotion and movement to the body.

What is the muscular system?

100

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?

100

An organism that obtain their chemical energy from an outside source (food).

What is a heterotroph?

100

Type of tissue that functions in the reception, processing, and transmission of information through impulses.

What is nervous tissue?

100

Organisms that are warmed mostly by heat generated internally by the metabolism; i.e humans and other mammals.

What is endothermic?

200

Disposal of metabolic wastes; regulation of osmotic balance of blood.

What is the excretory system?

200

A stimulus that amplifies a stimulus rather than reducing it.

What is positive feedback?

200

The overall flow and transformation of energy in an animal.

What is bioenergetics?

200

The type of tissue that holds many other tissues and organs together and in place; contains fibroblasts and macrophages. 

What is connective tissue?

200

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?

300

Skin and its derivatives (hair, claws, skin glands).

What is the integumentary system?

300

An animal that allows its internal condition to change in accordance with external changes in the variable. 

What is a conformer?

300

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?

300
The type of tissue responsible for voluntary movement.

What is skeletal muscle tissue?

300

The sensors for thermoregulation are located here. 

What is the hypothalamus?

400

Fills the spaces between cells to reduce friction and exchange materials like nutrients and wastes. 

What is interstitial fluid?

400

A set of physiological changes that occur roughly every 24 hours controlled by certain cyclic alterations in metabolism. 

What is a circadian rhythm?

400

An adapted physiological state of decreased activity and metabolism that enables animals to save energy while avoiding difficult and dangerous conditions.

What is torpor?

400

Polar side of the epithelia that faces the lumen or outside of the organ.

What is the apical surface?
400

Maintaining rate of heat gain that equals rate of heat loss.

What is the essence of thermoregulation?

500

The cavity in which the pleural cavity belongs. 

What is the thoracic cavity?

500

The gradual process by which an animal adjusts to changes in its external environment. 

What is acclimatization?

500

Transfer of heat between fluids that are flowing in opposite directions.

What is countercurrent exchange?

500

Single layer of ciliated cells that form a mucous membrane that sweep the film of mucus along the respiratory tract.

What is pseudostratified columnar epithelium?
500

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?
