Anatomical Terms
This term refers to the study of the structures of the body.
What is anatomy?
This is the body's ability to maintain relatively stable internal conditions despite changes in the external environment.
What is homeostasis?
Atoms and molecules make up this first level of organization in the human body.
What is the chemical level?
This term describes anything that has mass and takes up space.
What is matter?
This type of macromolecule includes sugars and starches and commonly serves as an energy source.
What are carbohydrates?
This is the standard reference position in which a person stands upright, faces forward, and has the arms at the sides with the palms facing forward.
What is anatomical position?
The relatively stable target value around which a variable is maintained is called this.
In a feedback loop, this component detects a change in a variable and sends information to the control center.
This level consists of cells working together to perform a particular function.
What is the tissue level?
In a chemical reaction, the substances present at the beginning of the reaction are called these.
What are reactants?
This is the smallest building block, or monomer, of a carbohydrate.
What is a monosaccharide?
A physician describes a patient's injury as being on the front surface of the body. This directional term is used to describe the location.
What is anterior?
In a feedback loop, this component detects a change in a variable and sends information to the control center.
What is the receptor/sensor?
The heart is an example of this level of organization because it is made of multiple tissue types working together.
What is the organ level?
A chemical reaction combines two or more substances to form one larger product. This type of reaction is occurring.
What is a synthesis reaction?
A cell needs to store and pass along the instructions used to build its proteins. The macromolecule responsible for storing this genetic information is this.
What is a nucleic acid?
This body plane divides the body into anterior and posterior portions.
What is the frontal (coronal) plane?
A person's body temperature rises. The brain detects the change and signals sweat glands to produce sweat, which helps lower body temperature. This type of feedback loop is being demonstrated.
What is a negative feedback loop?
The heart, blood vessels, and blood work together to perform related functions. Together, they represent this level of organization.
What is the organ system level?
A chemical reaction breaks one larger molecule into two or more smaller substances. This type of reaction is occurring.
What is a decomposition reaction?
A large molecule is broken into smaller molecules when water is added during the reaction. This process is occurring.
What is hydrolysis?
A patient reports pain in the lower, middle portion of the abdomen, in the region directly inferior to the umbilical region. What abdominopelvic region would this be located in?
What is the hypogastric (pubic) region?
During childbirth, stretching of the cervix causes the release of hormones that increase uterine contractions. Stronger contractions cause additional stretching, which continues until birth. This type of feedback loop is being demonstrated.
What is a positive feedback loop?
A structure contains epithelial tissue, connective tissue, muscle tissue, and nervous tissue, all working together to perform a specific function. This structure represents this level of organization.
What is an organ?
A reaction begins with two compounds and produces two different compounds by switching their components. This type of chemical reaction is occurring.
What is an exchange reaction?
A protein can speed up a chemical reaction in a cell without being consumed in the reaction. A protein performing this role is acting as this type of molecule.
What is an enzyme?
