A&P basics
This field studies the structure and physical relationships of body parts.
What is anatomy?
The smallest units of life.
What are cells?
Homeostasis refers to maintaining this type of internal environment.
What is a stable internal environment?
The smallest stable unit of matter.
What is an atom?
According to cell theory, all new cells come from the division of these.
What are preexisting cells?
This field studies how body structures work and perform their functions.
What is physiology?
Specialized groups of similar cells working together form this level of organization.
What are tissues?
Body temperature, blood glucose, blood pH, and blood pressure are all examples of this.
What are homeostatic conditions/variables?
The positively charged subatomic particle found in the nucleus.
What is a proton?
The selectively permeable boundary that surrounds a cell.
What is the cell (plasma) membrane?
Anatomy that studies structures visible to the unaided eye is called this.
What is gross (macroscopic) anatomy?
Histology is the study of these.
What are tissues?
The type of feedback that reverses a change and brings conditions back toward normal.
What is negative feedback?
The negatively charged particle that occupies the electron cloud.
What is an electron?
The movement of particles from an area of high concentration to low concentration.
What is diffusion?
The study of structures too small to see without magnification is called this.
What is microscopic anatomy?
An organ is composed of more than one of these.
What are tissue types?
The normal target value around which a homeostatic variable fluctuates.
What is a set point?
The total number of protons in an atom is called this.
What is the atomic number?
The diffusion of water across a selectively permeable membrane.
What is osmosis?
The idea that the shape of a body part influences how it works is known by this phrase.
What is form dictates function?
Name the four primary tissue types found in the human body.
What are epithelial, connective, muscle, and neural tissues?
Blood clotting is an example of this type of feedback mechanism.
What is positive feedback?
Water's ability to act as a universal solvent is largely due to these weak attractions between polar molecules.
What are hydrogen bonds?
This type of transport requires ATP and can move substances against their concentration gradient.
What is active transport?
