An isotonic solution (or isosmotic solution) has the same osmolality or concentration of particles (285 mOsm) as the ICF or ECF. A hypotonic solution has a lower concentration and is thus more dilute than body fluids (Figure 1-18). A hypertonic solution has a concentration of more than 285 to 294 mOsm/kg. The concept of tonicity is important when correcting water and solute imbalances by administering different types of replacement solutions (see Figure 1-18) (see Chapter 4).

Cells respond to external stimuli by activating a variety of signal transduction pathways, which are communication pathways, or signaling cascades (Figure 1-12, C). Signals are passed between cells when a particular type of molecule is produced by one cell—the signaling cell—and received Autocrine Secreting cell Target cells Secreting cell targets itself Membrane signal molecule Hormonal Neurohormone secretion Neurohormone Blood Blood Secreting cell (neuron) Target cell Target cell Neurotransmitter Neurotransmitter Nerve cell Receptor on target cell FIGURE 1-11 Primary Modes of Chemical Signaling.
The matrix is like glue; however, it provides a pathway for diffusion of nutrients, wastes, and other water-soluble substances between the blood and tissue cells. Interwoven within the matrix are three groups of macromolecules: (1) fibrous structural proteins, including collagen and elastin; (2) adhesive glycoproteins, such as fibronectin; and (3) proteoglycans and hyaluronic acid. Collagen forms cablelike fibers or sheets that provide tensile strength or resistance to longitudinal stress. Collagen breakdown, such as occurs in osteoarthritis, destroys the fibrils that give cartilage its tensile strength.
