Blood flows through blood vessels to carry oxygen, nutrients and waste around the body. Find out about different types of vessels and role of blood. In contracting skeletal muscle, capillary blood flow and O2 diffusing capacity, as well as O2 flux, may increase two orders of magnitude above resting values.
