Tissue and Chemistry of Life Quiz

What is inflammation?

• A process that occurs when tissues are damaged

• A process that occurs when tissues are repaired

• A process that occurs when tissues are infected

• A process that occurs when tissues are healthy

What are the major symptoms produced by inflammation?

• Redness, heat, swelling, pain, and disturbance of function

• Redness, heat, swelling, numbness, and disturbance of function

• Redness, cold, shrinking, numbness, and normal function

• Redness, heat, shrinking, pain, and normal function

What is the role of chemical mediators in inflammation?

• To decrease the speed of blood cells and other substances important for fighting infections

• To decrease the permeability of blood vessels

• To increase the permeability of blood vessels

• To prevent inflammation

What is the purpose of edema in the inflammatory response?

• To decrease the accumulation of pus

• To decrease the speed of blood cells and other substances important for fighting infections

• To decrease the pressure in the tissue

• To prevent the spread of infectious agents

What is the role of neutrophils in the inflammatory response?

• To produce pain sensations

• To increase the pressure in the tissue

• To fight infections by ingesting bacteria

• To decrease the speed of blood cells and other substances important for fighting infections

What is chronic inflammation?

• A brief period of inflammation followed by repair

• Prolonged inflammation resulting from the removal of the injury agent

• A process that occurs when tissues are healthy

• Prolonged inflammation resulting from the interference with the healing process

What are the effects of chronic inflammation?

• Increase in the spread of infectious agents

• Decrease in the severity of the injury

• Replacement of normal tissue by fibrous connective tissue

• Increase in the normal organ function

What are buffers in the context of acids and bases?

• Chemicals that have no effect on pH when acids or bases are added

• Chemicals that increase changes in pH when acids or bases are added

• Chemicals that resist changes in pH when acids or bases are added

• Chemicals that decrease changes in pH when acids or bases are added

What is the role of lipids in the body?

• A by-product of the breakdown of food molecules

• Involved with the extraction of energy from food molecules

• Regulate chemical reactions, serve as structural components, and cause muscle contraction

• Provide energy, serve as structural components, and regulate physiological processes

What is the basic unit of nucleic acids?

• Amino acids

• Fatty acids

• Nucleotide

• Monosaccharide
