multicellular organisms obtain their oxygen through the respiratory system
We obtain oxygen by breathing in fresh air. Carbon dioxide comes out of us.
No. The skeleton dose not get oxygen
Pterodactyls do not obtain oxygen at this time because they are extinct. While they existed, they probably obtained oxygen in the same way that birds today obtain it through the use of lungs.
Myoglobin is synthesized in muscle cells and imparts the reddish-brown color of skeletal muscle tissue. Like hemoglobin, myoglobin can combine loosely with oxygen. This ability to temporarily store oxygen reduces a muscle's requirement for a continuous blood supply during muscular contraction.
Plants obtain oxygen during photosynthesis from water molecules.
In order for the muscle fatigue to end the muscle cells must be provided with oxygen to 'burn' the lactic acid.
They absorb the oxygen from the cell which gets its oxygen from the blood
