Question

multiple choice question

what type of blood supply do muscle receive?

a generous amount
none at all
a small amount

Explanation:

Analyze muscle metabolic demands

Muscles are highly active tissues that require continuous delivery of oxygen and nutrients, as well as rapid removal of metabolic waste products like carbon dioxide and lactic acid. To sustain contraction, muscle fibers rely heavily on aerobic respiration, which demands a robust vascular network.

Evaluate vascularity of muscle tissue

Using the Skeletal Muscle Properties knowledge point, skeletal muscles are highly vascularized. This means they possess an extensive network of blood vessels and capillaries wrapping around individual muscle fibers to ensure efficient gas and nutrient exchange.

Assess the given options

• A generous amount: This matches the highly vascular nature of muscle tissue, which receives a rich, abundant blood supply to meet its high metabolic demands.
• None at all: This is incorrect, as avascular tissues (like cartilage) have no direct blood supply, whereas muscle is highly vascular.
• A small amount: This is incorrect, as a sparse blood supply would not support the intense metabolic activity required during muscle contraction.

Answer:

• A generous amount (Correct answer)
• None at all
• A small amount
