How do mammals conserve oxygen while diving?

• Mammals conserve oxygen by increasing metabolic rate and expanding lungs.
• Mammals conserve oxygen by swimming faster and using less energy.
• Mammals conserve oxygen by holding their breath and staying still.
• Mammals conserve oxygen by slowing heart rate, redirecting blood flow, using myoglobin, and collapsing lungs.

What process allows oxygen to move from the blood stream to body cells?

• Active transport
• Diffusion
• Filtration
• Osmosis
