Answer:
1. The blood vessel shown is a capillary.
2. The location where low oxygen blood and high carbon dioxide blood would be found is marked with the letter A in the diagram.
3. The diagram is based on structures found in the lungs, specifically the scheme of a pulmonary alveolus.
Explanation:
The scheme shows a pulmonary alveolus in contact with the corresponding pulmonary capillary, in addition to the alveolar blood flow. Between both structures is the <u>capillary-alveolus barrier</u>, through which gas exchange occurs.
- <em>According to what can be observed in the diagram, the vascular structure represented corresponds to the pulmonary </em><em>capillary,</em><em> a very small </em><em>blood vessel </em><em>whose epithelium allows the diffusion of gases.</em>
- <em>Just before the blood flow in the capillary comes into contact with the alveolus (marked with A in the diagram) the blood has a </em><em>high content of CO₂, and a low content of O₂</em><em>. Once it comes into contact with the alveolus, CO₂ will be released for removal and O₂ will enter, which is the result of alveolus-capillary gas exchange.</em>
- <em>The pulmonary alveoli are the structure at the end of the bronchial tract, which are located inside the </em><em>lungs</em><em>, the main organs of the respiratory system. The lungs are the ones that allow the act of breathing, carrying O₂ to the blood and eliminating CO₂.</em>
