Explain the role of blood in maintaining the internal enviornment | distrubes O2 and nutrients to the body, waste to lungs and kidneys, regulates body temp, carries hormones around, maintains fluid volume, protects against blood loss, WBC for infection. |
Define homeostasis. | Maintains a stable internal enviornment, regardless of the outside enviornment |
define the feedback mechanism. | feedback automatically returns the body to a homeostatic balance |
components of feedback | 1) receptor (sensor) 40c 2) Afferent pathway 3) control centre (thermostat)comand to sweat 4) Efferent pathway 5) Effector (aircon) sweats temp falls 6) response (returns to homeostasis) 37c |
