Which structure allows the passage of this oxygen to the environment
The respiratory system, specifically the lungs, allows the passage of oxygen to the environment.
Which two cell structures work together in the process of protein synthesis
The structure that allows the passage of oxygen to the environment is the respiratory system. Specifically, the organ responsible for facilitating the exchange of oxygen and carbon dioxide with the environment is the lungs. When you inhale, oxygen enters your body through the nasal passages or mouth, travels down the trachea (windpipe), then divides into smaller bronchi, bronchioles, and finally reaches the alveoli in the lungs. The thin walls of the alveoli allow for the diffusion of oxygen into the bloodstream, where it can be transported to the body's cells. During exhalation, carbon dioxide is expelled from the body through the same pathway.
To find out which structure allows the passage of oxygen to the environment, we can look at the respiratory system. In humans, oxygen is inhaled through the nose or mouth and travels down the throat into the trachea (or windpipe).
The trachea then branches into two bronchi, one leading to each lung. From there, the bronchi further divide into smaller and smaller tubular structures called bronchioles. At the end of the bronchioles, there are tiny air sacs called alveoli.
It is at the alveoli where the exchange of gases takes place. Oxygen diffuses from the alveoli into the surrounding capillaries, where it binds to red blood cells. These oxygenated red blood cells then travel throughout the body, delivering oxygen to cells and tissues.
So, to answer your question, it is the alveoli in the lungs that allow the passage of oxygen from the respiratory system to the environment.
