BIOMEDICAL ENGINEERING - EXAM1
Define the term "biomedical engineering". - Understanding biological systems, advance
the practice of medicine and, develop therapeutic technology and devices.
Distinguish Biomedical engineering from closely associated fields. - •Bioengineering
•Biological Engineering
---Often the same thing sometimes includes Agriculture & Environmental Science
•Biosystems Engineering
---More focused on agriculture and environmental science
•Biomolecular Engineering
---Manipulation of biomolecules
•Biochemistry
---Branch of chemistry that studies the chemical rxns across biology
•Biochemical Engineering
•Bioprocess Engineering
---The creation of new chemical products using biological organisms or components.
•Biotechnology
---DNA & RNA Manipulation
What are three common entry level jobs for biomedical engineers with a BS degree? (B)
Which of the three sounds most interesting to you? (C) Why? - Product Design
Engineer
Quality Engineer
Regulatory Affairs Associate
What is meant by the term "Tissue Engineering"? - The practice of combining scaffolds,
cells, and biologically active molecules into functional tissues.
What is meant by the term "Personalized Medicine"? - The practice of tailoring medical
decisions, practices, interventions and/or products to the individual patient based on
relevant biomarkers from that patient.
How are advances in imaging driving improved healthcare? - Being able to see inside
the body without invasive procedures.
(A) List the most common elements found in the human body and (B) the four classes of
biopolymers that they comprise. - (A) Hydrogen, Oxygen, Nitrogen, Carbon
(B) Polysaccharides, Lipids, Proteins, Nucleic Acids.
, (A) List the various subcompartments where water is distributed in the human body and
(B) their approximate percentage of total body water. - Intercellular Fluid (40%)
Extracellular Fluid(20%)
•Interstitial Fluid (Between Cells): 15%
•Intravascular Fluid: 5%
Approximately 60%.
(A) Using a common set of small molecules as examples explain the difference between
polar and non-polar molecules. (B) Why is polarity important to living systems? - Water
is bonded by polar-covalent bonds which creates a dipole and partial charges on the
molecule.'s elements. Non-polar molecules do not dissolve in polar solutions. Polarity is
crucial for life because it allows for the interaction of non-polar molecules,
transportation, and absorption of different nutrients.
What is meant by the term "polymer". - Many Parts. A macromolecule. Network of
entangled or cross-linked chains of repeating monomers.
(A) List the four major types of biological polymers (biopolymers) and (B) provide a
simple chemical or structural representation of each. - Lipids, polysaccharides, nucleic
acids, and proteins.
see cards.
Describe what is meant by the term "condensation reaction" and provide an example. -
Water is produced.
(A) What is a polysaccharide? (B) Where are they commonly found in the human body?
(C) What role(s) do they serve? - A sugar or a carbohydrate. In glucose which stores
energy for the body to use.
What is the general chemical structure of a lipid molecule? - Hydrophilic head.
Hydrophobic tail.
What molecules are found in all cell membranes and how are they organized, that is,
which end of the molecule faces the extracellular fluid (ECF) and which end is buried
inside the bilayer? - Cell membrane is is made up of a phospholipid bilayer. Fatty Acids
(lipids) make up this bilayer by situaing their hydrophobic tails buried inside and their
hydrophobic heads outside able to interact.
Describe two roles of cell membranes - Permeability to small molecules.
Protection to the cell.
