What happens to the various anion levels in the bloodstream during diabetic ketoacidosis?

A. The process by which the body automatically reacts to tissue injured by trauma or bacteria: This specifically describes the inflammatory response, which is a part of innate immunity, but not the definition of the system as a whole.

B. The set of proteins that enhance the ability of the body to initiate the inflammatory response, attack a pathogen, and remove damaged cell material: This describes the complement system, a specific group of proteins in the blood.

C. The process in which endothelial cells are separated from each other, making the capillaries larger: This describes increased capillary permeability, a physiological change that occurs during inflammation.

D. The general pathogen fighting system people are born with that does not change over time: Innate immunity is our first line of defense. It is non-specific, present from birth, and unlike adaptive immunity, it does not "learn" or change its method of attack upon re-exposure.

A. Individuals with Down syndrome commonly experience clotting disorders. Clotting disorders are not a hallmark feature of Down syndrome, though they have a higher risk for leukemia.

B. Individuals with Down syndrome commonly experience intellectual disabilities. Down syndrome (Trisomy 21) is characteristically associated with varying degrees of intellectual disability and developmental delays.

C. Individuals with Down syndrome commonly experience bone marrow suppression. This is typically a side effect of chemotherapy or specific anemias, not a primary developmental characteristic of Down syndrome.

D. Individuals with Down syndrome commonly experience muscular hypertrophy. The opposite is true; newborns with Down syndrome typically present with hypotonia (low muscle tone), often called "floppy baby syndrome."
