Chapter 1
Divides the body into superior and inferior parts.
What is transverse plane?
This type of bond forms when electrons are shared.
What is a covalent bond?
Movement of molecules from high to low concentration without energy.
What is diffusion?
Structure is related to function; each structure is designed for its function.
What is Principle of Complementarity?
Structures composed of two or more tissue types working together (e.g., heart).
What is organs?
This body system supports the body and protects organs.
What is skeletal system?
A substance with a pH below 7.
What is an acid?
When vesicles release substances outside the cell.
What is exocytosis?
Breaks down waste and contains digestive enzymes.
What is lysosomes?
Phase when sister chromatids are pulled apart.
What is anaphase?
This feedback type occurs during childbirth and blood
What is positive feedback?
Heterogeneous mixtures that contain large, visible solutes that do settle out.
What is suspensions?
The engulfing of large particles, like bacteria, by the cell.
What is phagocytosis?
Prevent leakage between cells.
What is tight junctions?
Uses transport proteins but does not require ATP.
What is Facilitated Diffusion?
This homeostatic control monitors the environment, responds to stimuli, and sends information to the control center (input).
What is receptor?
Reactions result in a net absorption of energy (use up energy). Ex: anabolic reactions
What is Endergonic reactions?
Structure that forms the mitotic spindle during cell division.
What is the centrosome (or centrioles)?
Resist abrupt and large swings in pH.
What is buffers?
Globular proteins unfold and lose their functional 3-D shape
What is denaturation?
This serosa covers organs in the cavity.
What is visceral serosa?
Also called displacement reactions, involve both synthesis and decomposition.
What is exchange reactions?
This type of RNA forms ribosomes.
What is rRNA?
Atoms are reduced when they gain electrons and oxidized when they lose electrons.
What is reduction-oxidation or redox reactions?
Reactions involve atoms or molecules combining to form larger, more complex molecule. Used in anabolic (building) processes.
What is synthesis (combination) reactions?
