Oxygen and other gases pass through the capillaries.
The function of the blood vessel is to pass oxygen through the body via the blood.
With one exception, veins carry oxygen-poor blood back to the heart. The largest and last blood vessel they pass through is called the superior vena cava. The exception is the Pulmonary Vein, which carries oxygen-rich blood from the lungs to the heart to be pumped to the rest of the body.

Nutrients pass through the capillaries (a type of blood vessel) in the small intestine.
vains pass through the outer layer of the lung and the oxygen (being soluble) passes through and oxygenates the blood
Oxygen and carbon dioxide easily pass back and forth between the alveoli and the blood through the capillaries.
A stroke occurs when there is a blocked vessel in the brain. If there is a blockage, no oxygen will pass through, thus a stroke occurs. It's not a heart disease nor is it a disorder.

The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
Thrombosis is when a blood clot forms inside a blood vessel. This causes a blockage in the circulatory system so that blood cannot pass through freely.
