What is the difference between anatomy and physiology?
anatomy refers to the form and physiology refers to it's function.

What is cell theory?
A cell is the basic structural and functional unit of living organisms. So, when you define cell properties, you are in fact defining the properties of life.
The activity of an organism depends on the collective activities of its cells.
According to the principle of complementarity, the activities of cells are dictated by their structure (anatomy), which determines function (physiology).
Continuity of life has a cellular basis. In other words, cells come from cells

This cell is spherical and produced by large lipid droplets in the cytoplasm.
fat cells

What are the 4 types of tissues make up all organs?
Epithelial tissue
Connective tissue
Muscle tissue
Nervous tissue
100
What is regeneration?
the replacement of destroyed tissue by the same kind of cells
200
What are the six levels of organization?
Molecules
Cells
Tissues
Organs
Organ system
Organism

How does the loss of cell homeostasis cause disease?
When the processes in our bodies that support homeostasis fail, cells may not get everything they need, or toxic wastes may accumulate in the body. If homeostasis is not restored, the imbalance may lead to disease or even death.
200
This cell is extremely important because it gathers information and controls our body functions.
nerve cells
200
What does epithelial tissue do?
Covers body surfaces and lines body cavities to form boundaries, protect, absorb, and filter
200
What is fibrosis?
repair by dense (fibrous) connective tissue, that is, by the formation of scar tissue
300
Kidney function, bone growth, and beating of the heart are all topics of anatomy. True or False?
False. These are topics of physiology.
300
What are the 4 elements that make up cells?
Carbon
Oxygen
Hydrogen
4. Nitrogen
300
These cells are responsible for reproduction.
egg and sperm cell
300
What does connective tissue do?
Supports, protects, insulates, transports, and binds other tissues together
300
What is a general (nonspecific) body response that attempts to prevent further injury. When inflammation happens, chemicals from your body's white blood cells enter your blood or tissues to protect your body from invaders?
Inflammation
400
What are the 11 organ systems?
Integumentary
Skeletal
Muscular
Nervous
Endocrine
Cardiovascular
Lymphatic
Respiratory
Digestive
Urinary
Reproductive

What are the properties of life, ie what characteristics make up all living things?
400
Our skin and the skin that covers our organs contain these cells.
epithelial cells
400
What does nervous tissue do?
The main component of nervous system organs that control regulation and communication
400
Is neoplasm cancer?
Yes, because it is an abnormal mass of proliferating cells.
500
At which level of structural organization is the stomach?
Which organ systems includes the trachea, lungs, nasal cavity, and bronchi?
Which system functions to remove wastes and help regulate blood pressure.
1. Organ
2. Respiratory
3. Urinary
500
What is the Principle of complementarity?
The principle of the complementarity of structure and function states that what a structure can do depends on its specific form. For example, bones can support and protect body organs because they contain hard mineral deposits
500
What is the main function of the neuron?
highly specialized nerve cells that generate and conduct nerve impulses
500
What does muscle tissue do? What are the 3 types of muscle tissue and what is their function?
Made of tightly packed together cells that allow for contractions to cause movement
Skeletal: muscles attached to bones that control voluntary movement
Smooth: muscles that involuntarily propel substances or objects along internal passageways
Cardiac: muscles of the heart that involuntarily contract to propel blood into circulation throughout the body
500
What are the two terms used to describe the increase and decrease in organ tissues?
Hyperplasia (increase) and atrophy (decrease)
