Anatomy & Physiology Flashcards
What is physiology?
Physiology deals with function. What the parts do & how they do it.
What is anatomy?
Anatomy is structure, the physical appearance. How it’s put together.
What is gross anatomy?
Gross anatomy deals with structures that can be seen with the naked eye.
What is microscopic anatomy?
Microscopic anatomy is also known as histology; it deals with structures as seen under a microscope.
What is systemic anatomy?
Systemic anatomy is studying anatomy on a systemic basis; studying an entire organ system
What is regional anatomy?
Regional anatomy is studying all of the structures in a specific area such as the hand.
What is cytology?
Cytology is the study of cells
What is embryology?
Embryology is the study of the developmental changes occurring before birth.
What is radio graphic anatomy?
Radio graphic anatomy is the study of the appearance body structures on X-Ray, CT, MRI, ultrasound and other imaging.
What is pathology?
Pathology is the study of abnormal anatomy, diseases.
What are the levels of organization smallest to largest?
The levels of organization are chemical, organelle, cell, tissue, organ, organ systems, organism
What are organelles?
Organelles are known as little organs. Each cell has one. Each one has a specific function. They are similar in all cells but may vary in number depending on the cell’a function.
What is a cell?
The cell is a basic unit of structure and function that can be alive independently. It varies in size and shape depending on their function.
What is a tissue?
A tissue is a group of specialized cells generally arranged in layers or masses. The cells all have similar structures and functions.
What is an organ?
An organ has at least two tissue types, usually more, arranged into a gross structure. It accomplishes specific functions. Heart, lung, brain, muscles
What is an organ system?
An organ system is a group of organs that contribute to a particular function. Organs that cooperate and work closely together to accomplish a common purpose: muscular system = movement
What are the characteristics of life?
The characteristics of life are movement, responsiveness, growth, reproduction, respiration, digestion, absorption, circulation, assimilation and excretion.
What are the requirements of an organism (to be considered an organism)?
The requirements to be considered an organism are water, food, O2, heat and pressure.
Why is water needed in organisms?
Water is needed in organisms for metabolic processes. It’s a medium for metabolic reactions. It’s needed to transport substances and it helps to regulate body temp via blood flow
Why is food needed in organisms?
Food is needed in organisms to supply energy, it gives raw material for production of various body substances that make up the structure of the body & also raw material for enzymes that regulate vital metabolic reactions
Why is O2 necessary in organisms?
O2 is necessary to release energy from food substances.
Why is heat necessary for organisms?
Heat is necessary to help regulate the rates of metabolic reaction.
Why is pressure needed in an organism?
Pressure is needed for breathing and for hydrostatic pressure to help circulate blood.
What is homeostasis?
Homeostasis is maintenance of a stable internal environment, means unchanging, it’s a dynamic state of equilibrium; internal conditions change but within narrow limits. It’s the body’s to maintain relative stability & function normally despite constant changes.
