hydrostatic

Examples of hydrostatic in the following topics:

• Types of Skeletal Systems

  • The hydrostatic skeleton, exoskeleton, and endoskeleton support, protect, and provide movement to the bodies of different types of animals.
  • A hydrostatic skeleton is one formed by a fluid-filled compartment within the body: the coelom.
  • This compartment is under hydrostatic pressure because of the fluid and supports the other organs of the organism.
  • Movement in a hydrostatic skeleton is provided by muscles that surround the coelom.
  • The skeleton of the red-knobbed sea star (Protoreaster linckii) is an example of a hydrostatic skeleton.

• Blood Pressure

  • Fluid will move from areas of high to low hydrostatic pressures.
  • In the arteries, the hydrostatic pressure near the heart is very high.

• Dead Space: V/Q Mismatch

  • This is a result of hydrostatic forces combined with the effect of airway pressure.

• Osmosis

  • This diffusion of water through the membrane—osmosis—will continue until the concentration gradient of water goes to zero or until the hydrostatic pressure of the water balances the osmotic pressure.

• The Plasma Membrane and the Cytoplasm

  • Water molecules will diffuse out of the hypotonic solution and into the hypertonic solution (unless acted upon by hydrostatic forces).

• Phylum Echinodermata

  • These tube feet can expand or contract based on the volume of water (hydrostatic pressure) present in the system of that arm.
