1
Q

How are red bloods cells specialised

A
  • biconcave shape which increases the surface area
  • means that the rate which oxygen moves in and out of the cell is faster
  • shape also makes them flexible

Q

How are neutrophils (WBC) specialised?

A
  • have a multi lobed nucleus which enables flexibility
  • means they can squeeze through small gaps when travelling to the site of infection
    -part of a non specific immune system

Q

How is alveoli adapted for diffusion

A
  • large surface area as it consists of one cell thick layer of squamous epithelium
  • means SA is larger and thinner making the diffusion distance quicker
    -also a large number of alveoli
