Ch 17: Online 3 Flashcards
Body Temperature and Metabolism
A chemical that reduces a fever
Antipyretic
Excessive heat may cause sweating to cease in order to preserve blood volume
Heat Stroke
Any substance that causes a fever
Pyrogen
Synthesis reactions
Anabolism
Air currents move warm air away from the skin surface
Convection
The part of the brain that regulates body temperature
Hypothalamus
Sweat glands that become more active in warm weather
Eccrine
The first stage of cell respiration
Glycolysis
Reactive molecules that may damage cell parts
Free Radicals
Organic molecules needed by the body in small amounts
Vitamins
Vascular response to a cold environment
Vasoconstriction
A process that does not require oxygen
Anaerobic
The site of most of the process of cell respiration
Mitochondria
Body heat is transferred to cooler objects not touching the skin
Radiation
The system that is the third stage of cell respiration
Cytochrome Transport
The hormone that increases heat production in stressful situations
Epinephrine
A process that requires oxygen
Aerobic
The second stage of cell respiration
Krebs Cycle
The hormone most responsible for regulating metabolism
Thyroxine
Body heat is transferred to cooler objects that touch the skin
Conduction
The state in which body temperature dorms below the normal range
Hypothermia
Degradation reactions
Catabolism
Inorganics needed by the body in small amounts
Minerals
Vascular response to a warm environment
Vasodilation
Muscular response to a cold environment
Shivering
