Module 1 Flashcards
Name the six essential characteristics of life
Organization, metabolism, responsiveness, growth, development, reproduction
Inter relationships among parts of an organism, each part has different specific, essential functions, together, they contribute to survival
Organization
Ability to use energy for growth and movement
Metabolism
Detect changes in our environment and response appropriately to those changes. Includes internal and external environments.
Responsiveness
An increase in the size or number of cells, cell reproduction, and growth is needed for adaptation, injury, repair, and tissue and organ maintenance
Growth
Cells differentiate throughout development, they change their specific structure to become specialized to do specific functions. Muscle, bone, and nerve cells have very different structures that facilitate their unique functions.
Development
Why is a stable internal environment necessary?
A variety of physiological functions require a consistent internal environment in order to operate properly
What is the standard of body temperature?
37°C
What happens at different rates at different body temperatures
Chemical reactions
What happens if our body temperature is too low?
Chemical reactions may be too slow to be effective
Cells can be damaged as well as molecules losing function, this is a especially important in the brain. What caused this?
Too high body temperature
Give three examples of body receptors
Skin, brain, organs
What part of the body detect changes in temperature?
Receptors
Where are the signals from the receptors sent?
Control centre or the brain
The process by which we maintain a stable internal environment
Homeostasis
