What happens to breathing and heart rate during exercise?
Breathing rate increases and heart rate decreases
They both increase
They both decrease
Why is the left wall of the heart have a thicker layer of muscle than the right side?
To stop the blood flowing backwards
To push the blood with more force at high pressure so it goes to all body cells.
To push the blood at high pressure to the lungs.
What is the name of the liquid part of the blood?
Platelets
Plasma
Red blood cells
What do platelets do?
They stick together and make fibres that make scabs (blood clots) that stop pathogens entering the blood or stop you bleeding to death.
They form your immune system and destroy pathogens.
They carry oxygen around the body attached to haemoglobin.
What do phagocytes do?
Engulf (surround) microbes and digest them.
Produce antibodies.
Release a toxin that kills pathogens.
Why do arteries have a thick muscle layer?
To provide energy for the blood vessel.
To prevent the blood flowing backwards.
To help withstand the high pressure blood, also to contract to control blood flow.
