The nose, pharynx, trachea, and bronchi.
The last valve oxygen-depleted blood must pass through before being pumped to the lungs is the pulmonary valve. This valve separates the right ventricle from the pulmonary artery and prevents blood from flowing back into the heart. Once the blood passes through this valve, it enters the pulmonary artery and travels to the lungs for oxygenation.
Carbon dioxide travels through both their bloods. All the cells of the baby and of the mother respire and produce carbon dioxide, which diffuses into the blood and circulates with it. In the mother, it eventually reaches her lungs where it diffuses into the alveoli and is breathed out. The baby has no functioning lungs, so when carbon dioxide rich blood travels through the umbilicus to the placenta, the carbon dioxide diffuses across to the mother's blood vessels, whence it proceeds to her lungs as before.
An example of a radiolucent structure is the lungs. In an X-ray image, the lungs appear darker because they allow X-rays to pass through easily due to their lower density compared to surrounding structures like bones or organs.
A blood cell must pass through two heart valves to travel from the brain to the lungs. As it exits the brain through the superior vena cava, it passes through the tricuspid valve, then through the pulmonary valve to reach the lungs for oxygenation.
A bullet passing through the left chest and exiting the right side may pass through the lung, ribs, possibly the heart, and muscle tissue. The exact number of structures can vary depending on the trajectory and angle of entry.

Oxygenated blood travels from the lungs through the pulmonary veins into the left side of heart, which pumps blood into the body. Good luck hope this helps ;)
yes they do
the air goes through the pharnyx then the trachea and into the lungs
The three structures you are looking for are the Asophagus, the Descending Aorta and the Vena Cava. Do not fall for the trap placed be asking for three structures, which might lead you to include the trachea in place of the vena cava. The trachea bifrucates at the level of T4 where it enters the lungs, far above the thoracic diaphragm.
Water can pass through the skin; they have lungs
It passes through the lungs.

Air or CO2 must pass through the respiratory system, specifically the lungs. During exhalation, these gases move out of the lungs and are expelled from the body through the nose or mouth.
Nutrient molecules pass from the small intestine into the through tiny structures called villi.
The air that is inhaled passes through the throat. More specifically, it passes through the trachea on its way to the lungs.
Well food does not pass through the heart, lungs, or bladder.
