Answer:
The correct answer is: Respiratory gases, option 1.
Step-by-step explanation:
Blood has two major components, cell phones and fluids. Within cell phones, the most representative cell of the blood system is the erythrocyte and, as for fluids, they are recognized as the great regulators of blood volume and blood pressure.
The first most recognized function of this blood system is the transport of gases, that is, the erythrocyte or red blood cell, which is the most representative cell, contains within its interior a protein called hemoglobin that has the ability to transport four oxygen molecules, This protein can bind to other gases such as carbon dioxide, but all of this depends on the partial pressures of the named gases in relation to the atmosphere we breathe and the dissociation curve of the gases based on hemoglobin.
The erythrocyte is an nucleated cell, that is, it does not have a nucleus, a biconcave specialized in transporting oxygen gas from the alveolus where homeostasis occurs to the tissue that requires oxygenation in an equitable manner in the body so that these remain vital, for that is that this function is the most recognized and could be said the most important.
