Chapter 1 Basics
This field studies the structure of body parts.
What is anatomy?
This directional term means toward the head or above.
What is superior?
This negatively charged particle occupies the space around an atom's nucleus.
What is an electron?
These are the three basic parts of a typical human cell.
What are the cell membrane, cytoplasm, and nucleus?
This passive process moves water across a selectively permeable membrane.
What is osmosis?
This field studies how body parts work.
What is physiology?
This directional term means farther from the point of attachment.
What is distal?
This bond forms when atoms share electrons.
What is a covalent bond?
This organelle modifies, sorts, and packages proteins.
What is the Golgi apparatus?
This passive process uses a membrane protein to move a substance down its concentration gradient.
What is facilitated diffusion?
This is the basic unit of structure and function in the human body.
What is a cell?
This body cavity contains the brain.
What is the cranial cavity?
O2 is this, while H2O is both this and a compound.
What is a molecule?
This organelle produces most of a cell's ATP.
What is a mitochondrion?
In this type of solution, water leaves a cell and the cell shrinks.
What is a hypertonic solution?
This process maintains a relatively stable internal environment.
What is homeostasis?
This organ system exchanges oxygen and carbon dioxide.
What is the respiratory system?
A solution with a pH of 3 is classified this way.
What is acidic?
Rough ER has these attached structures, while smooth ER does not.
What are ribosomes?
This process brings large material into a cell by forming a vesicle.
What is endocytosis?
This characteristic of life means detecting and reacting to change.
What is responsiveness?
These levels are ordered from simplest to most complex: atom, molecule, macromolecule, cell, tissue, organ, organ system, and this.
What is an organism?
This molecule provides usable energy for cell work.
What is ATP?
The lipid interior of this structure blocks some substances while proteins assist selected substances.
What is the phospholipid bilayer of the cell membrane?
These are the four stages of mitosis in order.
What are prophase, metaphase, anaphase, and telophase?
