Hi im bob and the answer is 4cm3455465x32 this is due to the high blood pressure
Capillaries carry Oxygenated (oxygen rich) blood and De-oxygenated (oxygen depleted) blood.
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.
Arterioles carry blood from larger arteries to capillaries. This blood is high in oxygen. Capillaries bring blood to cells which need oxygen for energy production.
Arteries, capillaries, and veins carry oxygen in the blood.
Capillaries - they are the smallest vessels that serve as arteries and veins.
capillaries
Nerve cells receive blood and oxygen through a network of small blood vessels called capillaries. These capillaries are located close to nerve cells in order to deliver nutrients and oxygen for their metabolic needs. The brain, for example, has a dense network of capillaries to ensure a constant supply of blood and oxygen to nerve cells.
Oxygen and other gases pass through the capillaries.
Capillaries are the smallest blood vessels in your body and act as the exchange point for oxygen.
Systemic Arteries carry oxygen rich blood (also called oxygenated blood). Pulmonary Arteries carry oxygen poor (deoxygenated) blood
Oxygen passes from the blood into organs through the wall of capillaries.
