Question | Answer |
Stimulus for eyes | Light |
Stimulus for nose | Chemicals in the air |
Stimulus for tongue | Chemicals in food |
Stimuli for skin | Temperature and pressure |
Stimulus for ears | Sound |
A detectable change in the environment | Stimulus |
Name the 5 sense organs | Eyes, ears, nose, skin, tongue |
Specialised cells found in sense organs | Receptors |
Cells that carry messages to and from the brain | Nerves |
The type of message carried along a nerve | Electrical impulse |
Two organs in the central nervous system | Brain and spinal cord |
The stimulus for plant shoots | Light |
The stimulus for plant roots | Gravity |
The response made by plant shoots in response to light | Positive phototropism |
The response made by plant roots in response to gravity | Positive gravitropism |
The substance that controls plant tropisms | Hormones |
The organ that regulates body temperature | Skin |
Can stand on end to trap air | Hair |
Controls the position of the hair | Erector muscle |
Structure that makes sweat | Sweat gland |
Tube that carries sweat to the surface | Sweat pore |
Releases sweat onto the surface of the skin | Sweat pore |
Response made by blood vessels when you're hot | Widen/ vasodilation |
Response made by blood vessels when you're too cold | Narrow / vasoconstriction |
Explain why sweating cools you down | Sweat evaporates using heat from your skin |
Explain why the blood vessels narrowing raises body temperature | Less blood flowing through skin - less heat lost |
Explain why blood vessels widening lowers body temperature | More blood flowing through the skin - more heat lost |
Explain why hairs standing in end raises body temperature | Thicker layer of air next to skin - air insulates - less heat lost |
Explain why hairs lying flat lowers body temperature | Thinner layer of air next to skin - more heat lost |
Hormone that reduces blood glucose | Insulin |
Organ that makes insulin | Pancreas |
How insulin reaches the liver | Blood |
Target organ for insulin | Liver |
Insulin cause glucose to be converted to ... | Glycogen |
HORMONE THAT RAISES BLOOD GLUCOSE LEVELS | GLUCAGON |
EFFECT OF GLUCAGON | CONVERTS GLYCOGEN INTO GLUCOSE |
Condition when you don't make enough insulin | Diabetes |
Three ways to treat diabetes | Regular insulin injections, low carbohydrate diet, pancreas transplant |
Chemical used to test for glucose | Benedicts (heat needed) |
Colour benedicts changes if glucose is present | Brick red |
Two fluids tested for glucose in diabetic patient | Urine, blood |
