| Size and shape has a direct effect on what? | How an animal exchanges materials with its environment | |
| Materials from environment are diffused in what? | An aqueous medium | |
| Increased complexity led to: | increased specialization to meet exchange needs | |
| What happens as number of cells increase? | Surface area to volume ratio increases | |
| What are cells? | basic component of life that carries out all essential functions | |
| What are tissues? | 1000s of same specialized cells with common function | |
| What are organs? | multiple types of tissues for common function | |
| What are organ systems? | combination of organs as part of integrated system | |
| What are specialized cells? | basic functions, but specialized for one task | |
| What is an organism? | all components orgaized into | |
| What are the 4 types of tissues? | Epithelial, Connective, Muscle, and Nervous | |
| What are 6 types of connective tissue? | Loose Connective, Adipose, Fibrous, Blood, Cartilage, and Bone | |
| What are 3 types of muscle tissue? | Skeletal, Smooth, and Heart | |
| What are 2 types of nervous tissue? | Neuron and glial cells | |
| How many organ systems are there? | Eleven | |
| What system releases hormones and has a slow gradual response? | Endocrine System | |
| What system transmits nerve impulses and has an immediate response? | Nervous System | |
| Why is system coordination important? | To increase efficiency | |
| What is homeostasis? | maintenance of internal “steady state” in face of external fluctuations | |
| What are 3 components of homeostasis? | stimulus sensor, set point, and response | |
| What is a regulator? | internal environment is regulated by control of mechanisms (endotherms) | |
| What is a conformer? | internal environment conforms to external environment (ectotherms) | |
| What aspect of homeostasis is most important? | temperature because of its effect of rate of metabolism | |
| Which takes more energy: regulating or conforming? | regulating due to metabolism, but they have advantage | |
| What are 4 ways to balance heat loss and gain? | radiation, evaporation, convection, and conduction | |
| Endotherms use these two additional adaptations to balance heat loss and gain: | insulation (blubber) and circulatory adaptations (blood flow) | |
| What is bioenergetics? | the flow or transformation of energy through an animal | |
| How is bioenergetics examined? | the basal metabolic rate |
