1) At what point is the amount of oxygen at its highest?
in the capillaries during strenous activity
in the lungs
in the capillaries at rest
in muscle tissue during strenous activity
2) You have diagnosed a patient with an iron deficiency. Themost likely result of this is
low carbon dioxide content
very red blood
low oxygen content
high oxygen content
3) Why are insects limited to relatively small sizes?
Their respiratory system relies on diffusion which is slow overlong distances
Their respiratory muscles are smooth muscle only
They have a closed circulatory system
Their exoskeleton cannot support larger-bodied animals
4) Air rushes into the lungs of humans during inhalationbecause
the volume of the thoracic cavity increases
pressure in the alveoli increases
the diaphragm contracts and pushes upward on the chestcavity
smooth muscle lining the trachea and bronchi contracts andcauses their volume to increase
