Unit 2.3 Metabolic rate Flashcards
The top chambers of the heart which receive blood entering a vertebrate heart
Atria
double circulatory system which completely separates oxygenated and deoxygenated blood (Birds & Mammals)
Complete Double Circulatory System
When the blood flows around the body it passes through the heart twice.
Double Circulatory System
Double circulatory system where oxygenated and deoxygenated blood are not completely separate Amphibians & Reptiles)
Incomplete Double Circulatory System
A place in a habitat which has little oxygen present (Deep sea, high altitude)
Low Oxygen Niche
The rate of energy consumption in an organism
Metabolic Rate
during a full circulation of the of the body, blood passes through the heart once
Single Circulatory System
chamber of a vertebrate heart that distributes blood.
Ventricles
The maximum volume of oxygen that can be absorbed by an organism in a certain period of time
VO2 Max
One method by which metabolic rate can be measured
Oxygen Consumption
Another method by which metabolic rate can be measured
Heat Production
Found in vertebrates, require large quantities of oxygen and efficient gas exchange systems
High Metabolic Rate
An animal which has an internal environment that is dependent on its environment, may have a narrow ecological niche
Conformer
the role of an organism in its community
Ecological Niche
The maintenance of a steady internal environment
Homeostasis
Region of the mammalian brain which monitors blood temperature
Hypothalamus
The control mechanism by which homeostasis is maintained by regulators
Negative Feedback
Animals that can adjust their metabolic rate to maintain a steady internal environment, wider range of possible ecological niches
Regulators
Cells in the hypothalamus that detect temperature changes in the blood
Thermoreceptors
The use of a negative feedback system to control the body temperature of mammals.
Thermoregulation
Conditions that include temperature, salinity and pH
Abiotic Factors
The requirements of organisms in terms of energy, low in conformers, high in regulators
Metabolic Costs
Responses carried out by conformers in order to maintain their optimum metabolic rate
Behavioural Response
Alveoli
Microscopic parts of the gas exchange system in vertebrate lungs
