What does a capillary do?
Exchange blood between muscles/tissue and veins/arteries
What does the CNS consist of?
Brain and spinal cord
What makes up the first line of defence?
Physical barriers, (Skin, Hair, Eye water, stomach acid, saliva)
Name some carbon sinks
A carbon sink is any reservoir that absorbs more carbon than it releases
- Ocean
- Land plants
- Soil
What is a consequence of low cardiovascular fitness?
Unable to do high intensity exercise, more susceptible to disease (high blood pressure, Cholesterol)
What is a neuron?
A type of cell that receives and sends messages from the body to the brain and back to the body
What is the second line of defense and how does it work?
White blood cells, travel to the part of the body where the pathogen has entered and engulf it, killing it
Name some carbon store/source
processes or areas where more carbon is released into the atmosphere than absorbed
- Fossil fuels
- Agriculture (incl deforestation)
- Volcanic eruptions
What are the four components of blood?
Platelets, Red blood cells, white blood cells, plasma
What is the PNS?
All of the neurons outside the CNS
What is the difference between B cells and T cells?
How do processes like photosynthesis and respiration contribute to the movement of carbon through ecosystems?
Photosynthesis: Converts CO2 and H2O into O2 and Glucose
Respiration: Converts O2 and Glucose into CO2 and H2O
They both take and add carbon to the atmosphere
What do the nodes do in the heart?
SA node and AV Node send electrical impulses that contract the atriums and ventricles
What is the synapse?
The site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron
What are some of the white blood cells called? (name at least one
What is the difference between the natural greenhouse effect and the enhanced greenhouse effect?
Natural keeps carbon in the atmosphere and is the reason we have a stable climate (14 degree surface temp)
Enhanced puts more carbon in the atmosphere creating an environment which holds more heat
What are the names of the four valves and where are they?
Tricuspid valve: Between right atrium and ventricle
Mitral Valve: Between left atrium and ventricle
Aortic Valve: At the base of aorta
Pulmonary valve: At the base of pulmonary artery
If I was to touch a hot stove, how would my CNS and PNS work together to create a reaction?
PNS would detect the warmth, and send the info to the CNS where the message is interpreted and a response generated, this is sent to the PNS which carries out the response
Why do B cells inactivate but not kill a pathogen?
B cells lock antibodies into the antigens of pathogen which prevents it from binding to body cells
Name a policy created to combat climate change
- Paris Agreement (2015)
-Kyoto Protocol (1997)
-Inflation Reduction Act (2022 )
-Renewable Energy Target (RET
- Carbon taxes
