Increase and Decrease of Blood pressure
Being overweight,Stress,High Alcohol Intake,Smoking Regular Exercise, Balanced Diet
1 of 11
Analyse the results of a different ways of measuring fitness the ability strength stamina flexibility agility speed and cardiovascular efficiency
carbon monoxide reduce the oxygen carrying capacity of the blood so heart rate increase to compensate and nicotine increase heart rate
2 of 11
Blood pressure(1)
saturated fats leading to a build up of cholesterol as plaque in arteries and high levels of salt elevating blood pressure
3 of 11
Blood pressure(2)
carbohydrates are stored in the liver as a glycogen or converted to fats and fats are stored under the skin and around organs as adipose tissue and proteins are not stored
4 of 11
EAR and BMI
Ear in g = 0.6 x body mass in kg and BMI=mass in kg/(height in m )2
5 of 11
Explain the difference between passive (receive antibodies) and active immunity (make own antibodies).
• harmless pathogen given which carries antigens • antigens trigger immune response by white blood cells which produce antibodies • immunity remains (memory cells produced).
6 of 11
Explain how the eye focuses light (accommodation) from near and distant objects.
• cornea – refracts light • iris – controls how much light enters pupil • lens – focuses light on to retina • retina – contains light receptors, some sensitive to light of different colours • optic nerve – carries impulses to the brain.
7 of 11
Explain the action of depressants and stimulants on the synapses of the nervous system:
• depressants bind with receptor molecules in the membrane of the next neurone blocking the transmission of the impulses • stimulants cause more neurotransmitter to cross the synapse.
8 of 11
Recall examples of drugs:
depressants, limited to alcohol, solvents and temazepam • pain killers, limited to aspirin and paracetamol • stimulants, limited to nicotine, ecstasy and caffeine • performance enhancers, limited to anabolic steroids • hallucinogens, limited t
9 of 11
Explain the basis of the legal classification of drugs:
Class A being the most dangerous with the heaviest penalties • Class C being the least dangerous with the lightest penalties.
10 of 11
Describe how the liver can become damaged as it removes alcohol (cirrhosis), to include:
enzymes in liver breakdown alcohol • toxic products of alcohol breakdown cause liver damage
