Humans have ____ for body temperature, blood glucose concentrations, electrolyte concentrations, pH levels, tendon tension and variables.
A
positive feedback mechanisms
B
set points
C
a wide internal range
D
no regulation
Explanation: 

Detailed explanation-1: -Thermoregulation is coordinated by the nervous system (Figure 11.2). The processes of temperature control are centered in the hypothalamus of the advanced animal brain. The hypothalamus maintains the set point for body temperature through reflexes that cause vasodilation or vasoconstriction and shivering or sweating.

Detailed explanation-2: -Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis (“steady state”). These changes might be in the level of glucose or calcium in blood or in external temperatures. Homeostasis means to maintain dynamic equilibrium in the body.
