Anatomy & Organization
The study of body structure and relationships among body parts.
What is anatomy?
The maintenance of a relatively stable internal environment.
What is homeostasis?
This organelle contains most of the cell's DNA.
What is the nucleus?
The four stages of mitosis can be remembered with these four letters.
What is PMAT?
This type of transport requires no ATP.
What is passive transport?
The study of how body structures work and function together.
What is physiology?
The ideal normal value or range for a body variable.
What is a set point?
These structures build proteins.
What are ribosomes?
During this stage, chromosomes condense.
What is prophase?
Net movement from an area of higher concentration to lower concentration.
What is diffusion?
These are the basic structural and functional units of the body.
What are cells?
These three parts detect, decide, and respond in a feedback system.
What are the receptor, control center, and effector?
This organelle produces most of the cell's ATP.
What are mitochondria?
During this stage, new nuclei form.
What is telophase?
This transport uses ATP and can move substances against the concentration gradient.
What is active transport?
Epithelial, connective, muscle, and nervous.
What are the four basic tissue types?
This type of feedback opposes or reverses the original change.
What is negative feedback?
During this process, DNA information is copied into messenger RNA.
What is transcription?
During this stage, chromosome copies separate.
What is anaphase?
This process brings large materials INTO the cell using vesicles.
What is endocytosis?
Molecules → organelles → cells → tissues → organs → organ systems → _____.
What is an organism?
Childbirth contractions are an example of this.
What is positive feedback?
During this process, a ribosome reads mRNA while tRNA brings amino acids to build a protein.
What is translation?
During this stage, chromosomes line up in the middle.
What is metaphase?
One forms a passageway through the membrane; the other binds a molecule and changes shape to move it across.
What are channel proteins and carrier proteins?
