Chapter 1: Bio Fundamentals Flashcards
Define Anatomy and Physiology.
Anatomy is the study of structure. Physiology is the study of how body parts function
What are the six levels of structural organization? Give examples
- Chemical (Oxygen)
- Cellular (Blood cell)
- Tissue (Connective)
- Organ (Liver)
- Organ system (Digestive system)
- Organismal (Person)
Define Metabolism
A biochemical process that converts food into energy
Define Homeostasis
A condition of balance in the body’s internal environment maintained by regulatory processes
Define interstitial fluid
Fluid found between cells in a tissue
How do feedback systems maintain homeostasis?
- Receptor monitors changes and sends an input
- Control center evaluates the input and generates an output
- Effector receives output and produces a response
What is negative feedback?
Continues feedback loop until a “set point” is reached
What is positive feedback?
Continues feedback loop until external mechanism interrupts cycle
What are possible outcomes of homeostatic imbalance?
Can result in disease, disorder, or death
What is anatomical position and why is it important?
A standardized method of observing that allows for consistent anatomical reference.
