AQA Biology Unit 2 - Homeostasis

HideShow resource information

Banting and Best: discovered the treatment of insulin for diabetics

Blood: transporter of hormones

Blood Vessels: narrow or constrict depending on blood temperature, influencing blood flow to the skin's surface capillaries 

Capillaries: when the body is trying to lose heat, blood flow in the capillaries is increased

Carbon Dioxide: a waste product from respiration which needs to be maintained at low levels, leaves the body via the lungs when we exhale

Constrict: 'narrow' - restricting blood flow (via capillaries) when blood  temperature is too low, reducing heat loss

Coordinator: the 'decision making' part of the Homeostatic mechanism

Deamination: the process of the breakdown of amino acids in the liver

Denature: enzymes will not function when temperatures become too high

Dilate: 'widen' - increasing blood flow (via capillaries)

Effector: the body parts which respond to nervous impulses sent from the brain and produce the appropriate response

Excreted: metabolic waste products are excreted from the body




A set of keywords and definitions concerned with homeostasis which is  a topic found in most GCSE Biology specifications. Learning these definitions is always a useful starting revision exercise and this could be matched up with a set of written notes with good diagrams.



Thank you for this resource. I found it really useful to check my knowledge from last lesson and fill in the gaps. I turned the information on her into flash cards. Thank you again.
