Oxygen is inhaled through the lungs where it diffuses across the lung membrane into tiny blood vessels called capillaries. From there, oxygen binds to hemoglobin in red blood cells and is transported throughout the body to be used by cells for energy production.
Inhaled oxygen will diffuse through the walls of the lungs. It will also diffuse through the walls of red blood cells so it can be carried all over the body.
The alveoli are the sites of respiration: the oxygen in them provided by the inhaled air diffuses into the blood cells that flow through the capillaries. Carbon dioxide diffuses out of the blood and into the alveoli so it can be exhaled. The capillaries provide a way for the blood to reach the alveoli. Hope this helps
The respiratory system is lined with a mucous membrane that secretes mucus.

When you inhale, air fills the alveoli and oxygen passes from the alveoli through a semipermeable membrane and into the capillaries, leading into the bloodstream. During the same process, carbon dioxide is outgassed from the blood to the alveoli When you inhale, air fills the alveoli and oxygen passes from the alveoli through a semipermeable membrane and into the capillaries, leading into the bloodstream.

The capillaries in the excretory (urinary) system are called glomeruli. They filter out waste out of the blood through a series of fenestrations (holes), basement membrane and podocytes which have long thin fingers that keep the larger molecules from escaping.
Blood does not move faster through the capillaries. Blood flow is slowest in the capillaries.
