BiologyHomeostasisGCSEAQA Created by: tonisha_Created on: 17-01-23 20:13 What is the normal human body temperature? 37 degrees 1 of 23 The body temperature is monitored and controlled by what? the brain 2 of 23 This part of the brain is called what? thermoregulatory centre 3 of 23 The thermoregulatory centre contains _______ which are ________ to the temperature of the _____? contains receptors which are sensitive to the temp of the blood 4 of 23 The skin also contains __________ and sends ______ ________ to the __________ centre? contains receptors and sends nervous impulses to the thermoregulatory centre 5 of 23 IF BODY TEMP IS TOO HIGH ---------------------------------- ________ glands will release _______ onto the surface of the ______? sweat glands release sweat onto the surface of the skin 6 of 23 It will then what? evapourate 7 of 23 This transfers _______ to the _______? energy to the surroundings 8 of 23 The second way is that the blood ______ beneath the skin are supplied blood by the blood ______? blood capillaries blood vessels 9 of 23 If body temp is too high, the blood vessels will _____ ( get _______) ? dilate (get wider) 10 of 23 What is the keyword for this? vasodilation 11 of 23 This means that more blood can ______ through the ________ helping transfer ______ out of the _______ to the environment? more blood can flow through the capillaries helping transfer heat out of the blood to the environment 12 of 23 Then the body temp is back? to normal 13 of 23 IF BODY TEMP IS TOO LOW ------------------------------ _______can stand up to trap _______ layer of air? hairs insulating layer of air 14 of 23 The blood vessels supplying the ______ with _____ will ______ (become ______)? supplying the capillaries with blood will constrict (become narrower) 15 of 23 What is the keyword for this ? vasoconstriction 16 of 23 This means that less ______ is flowing through meaning less _____ is ______ from the body? less blood is flowing through the body meaning less heat is lost 17 of 23 Another way is by doing what? shivering 18 of 23 This is where your ______ muscles will ______? skeletal muscles contract 19 of 23 To generate energy for this, the muscles cells will increase what? their rate of respiration 20 of 23 This releases _____ which warms the body? heat 21 of 23 Body temp is now back? to normal 22 of 23 Controlling body temp is an example of what? homeostasis 23 of 23
