Answer:
In a patient who has low blood oxygen levels, although his blood is circulating properly, is most likely that alveoli are functioning improperly.
Explanation:
The supply of oxygen to the blood depends on the breathing process, performed by the respiratory system.
At the level of the pulmonary alveoli occurs gaseous exchange, this is the entry of oxygen from the inspired air and the elimination of CO₂ resulting from cell metabolism. If the alveoli do not function properly, the gas exchange will be deficient and there will not be enough oxygen in the blood and tissues.
The other options are not correct because of:
<u><em>Capillaries
, aorta and pulmonary vein </em></u><em>are part of the circulatory system, on which the oxygenation of the tissues depends, not the oxygen content of the blood.</em>

The odorant molecules arrive either directly by diffusion into the mucus, or are supported by transport proteins (odor binding protein or OBP) that allow the hydrophobic molecules - majority - to penetrate the mucus covering the epithelium, and thus to reach the membrane receptors present on the eyelashes of the olfactory neurons. These transport proteins are thought to concentrate odorant molecules on membrane receptors. As ligands, the odorant molecules bind to membrane receptors on the eyelashes, triggering a transduction pathway for a stimulus involving G.olf protein (first messenger), adenylate cyclase, and cAMP ( second messenger). The second messenger causes the opening of ion channels Ca2 + / Na + present on the plasma membrane of the olfactory receptor, these two ions then enter the cell. Ca2 + causes the opening of a Cl- channel, the output of this ion causes depolarization of the membrane so that the olfactory receptor produces action potentials. These impulses will go directly to the olfactory bulb, in the prefrontal region of the brain, where this information (and that of taste) is processed by the body.
Answer:
Drug Synergism. An interaction between two or more drugs that causes the total effect of the drugs to be greater than the sum of the individual effects of each drug. A synergistic effect can be beneficial or harmful.
