That is the small intestine. (The small intestine is actually longer than the large intestine.)
The oxygen is passing from through the walls of the capillaries and the organs' walls. There are specially designed proteins which are allowed from the cell, to pass through the cell's wall (membrane).
The lungs of the mother breath in the air. The lungs put the oxygen in the red blood cells. The blood flows through the walls of the uterus and through the umbilical cord into the blood stream of the fetus. The venus blood supply returns through a vein in the cord back into the mother and the lungs and the cycle repeats until the cord is cut.
It passes through the wall of the digestive system, then into the blood.
yes capillaries are connected to heart because heart is a muscular organ and the exchange of materials between heart walls and blood occurs through capillaries.
Wastes and nutrients are carried in the blood and diffuse across the capillary walls.
Oxygen passes from the blood into organs through the wall of capillaries.

yes Actually, 'yes' is not the correct answer. Drugs, just as food, 'pass' through the walls of the small intestines into the blood stream.
Inhaled oxygen diffuses through the walls of the alveoli in the lungs into the surrounding capillaries, where it binds to hemoglobin in red blood cells for transport to tissues in the body.
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.
