.......... Is the process of maintaining a constant internal environment in living organisms
homeostasis
...........Is the maintenance of a relatively constant body internal environment.
Regulation
This is immediate surroundings of the cells comprising of interstitial (Intracellular), intercellular or tissue fluid.
Internal environment
Is the medium from which cells obtain their requirements and through which cells discharge their waste products.
Tissue fluid
Tissue fluid contains the same composition as blood but lacks cells and ..............
Plasma proteins
Excess fluid is drained into the lymphatic vessels to form ..........
Lymph
When a factor in the body such as blood sugar level drops or rises above normal, it is detected, and then corrective action is taken to bring it back to normal. Such a response is called ..........
NEGATIVE FEEDBACK
If the change below or above the normal is not corrected but instead there is further deviation, this is called ..........
POSITIVE FEEDBACK
............Is the condition that occurs when the body temperature falls than the normal, whereby.......... Is the condition which occurs when the body temperature increases above normal
Hypothermia, Hyperthermia
.........Is the increase of diameter of arterioles near the surface of the skin. This enables more blood to flow near the surface of the skin and more heat is lost to the surrounding by conduction, convection and radiation.
Vasodilation
.................Is the decrease of arterioles diameter near the skin surface. This decrease blood flow near the skin surface hence less heat is lost to the surrounding by conduction, convection
Vasoconstriction
.........Is an involuntary rhythmic contraction of muscles which serves to generate heat during cold weather.
Shivering
During hot weather condition metabolic rate ......... therefore less heat is generated and hence the body temperature falls.
decrease
During hot weather condition, erector Pilli muscles ..........making the hair to lie flat on the skin surface to encourage loss of heat from the body by radiation and convection.
relax
Dogs and cats cool their bodies through hanging out of their tongues to allow heat loss through...........
evaporation.
