which muscle fiber has a large supply of blood vessels running through it

Solution

‘Slow-twitch’ muscle fibres (type I) have a richer blood supply and use oxygen to help release energy through aerobic respiration, which makes them resistant to fatigue.

Skeletal muscles consist of 100,000s of muscle cells (\"muscle fibers\"). They perform the functions of the specific muscle of which they are a part. Muscle fibres are the basic functional units of muscle tissue - which is special because it has the ability to contract, producing movement or force.

Muscles that contain a lot of slow twitch fibres are red, because they contain lots of blood vessels. Slow twitch muscle fibres rely on a rich supply of oxygenated blood as they use oxygen to produce energy for muscle contraction.
