50
Q

double membrane surrounding the lungs

A

Pleura

51
Q

Homeostatic control of breathing

A
  • chemoreceptors in aorta sense changes in blood CO2 concentration
  • CO2 increases: chemoreceptors send impulses to respiratory(R) and cardiovascular(C) centers, R stimulates faster breathing, C stimulates faster pumping of heart
  • blood flows faster
  • CO2 exhaled faster
  • CO2 blood concentration normalises
52
Q

adaptations for GE in locusts.

A
  • GE happens through tracheole system (TS)
  • air enters spiracles
  • TS holds network of trachea
  • thin walls, moist
  • gases diffuse between the surface

A
  • ciggies contain nicotine, tar and CO
  • cause arterial walls to harden
  • stimulates secretion of adrenaline -increase blood pressure, heart rate, stroke
  • tar paralyses cilia and accumulates
  • emphysema
