Question 8

what are capillaries?

Answer 8

Capillaries are small blood vessels which allow nutrients to pass across the membrane into nearby cells

Question 9

why does your heat rate increase during exercise?

Answer 9

This is because your muscles cells need more glucose and more oxygen to allow for respiration
