Measures the concentration of hydrogen ions in a solution.

Normal blood pH is approximately 7.4.

Macromolecules that serve as cellular fuel, primarily glucose.

Macromolecules that store energy.

Macromolecules that aid in the transport of substances.

Macromolecules that store and transmit genetic information.

Body posture: erect, palms forward, feet apart.

LUQ: stomach, LLQ: small intestine, RUQ: liver, RLQ: appendix.

Redness, heat, swelling, pain, impairment of function.

Stable internal conditions despite external changes.

Response decreases or shuts off the original stimulus.

Response enhances or exaggerates the original stimulus.

Gains water; causes cells to swell.

Loses water; causes cells to shrink.

No net movement of water; cell size remains constant.

Allows certain materials to move while restricting others.

Protection, absorption, filtration, excretion, secretion, sensory reception.

Skeletal: voluntary; Cardiac: involuntary; Smooth: involuntary.

Some can regenerate (bone, epithelial); some cannot (cardiac muscle, nervous tissue).

Movement across cell membranes without energy (includes diffusion, osmosis).

Ductless glands that secrete hormones into the bloodstream.

Glands that release substances through ducts onto body surfaces.

Immature form of cells like fibroblasts (connective tissue).

Mature form of cells, like chondrocytes (cartilage).
