It gets oxygen and nutrients through simple diffusion.
Bone contains capillaries but cartilage does not.
Oxygen enter the capillaries by diffusion due to difference in oxygen concentrations.
False, bone contains capillaries.
It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
Capillaries
Capillaries contain oxygenated blood.
Capillaries exchange food, oxygen, and carbon dioxide.
Oxygen passes into the capillaries that surround the alveoli. The thin walls of the capillaries make this diffusion easier.
greater concentration of oxygen in the air sacs of the lungs than in the capillaries.
Tissue without capillaries is called avascular tissue. Examples of avascular tissue include:CartilageEpitheliaCorneaLensAll organs contain blood vessels.
Capillaries change color as they pass by body cells as the blood they contain loses oxygen. Oxygen-rich blood has a brighter color than oxygen-poor blood.
