流入四肢的血液供应皮肤、皮下组织、肌肉和骨骼。而流向肢体的骨、神经和结缔组织的血流相对恒定，流向皮肤和肌肉的血流则有很大的变化。皮肤的循环，特别是四肢的循环，是由温度调节的需要决定的，这样，由于局部或环境温度的变化，就会发生静止肢体中血流的任何变化。在运动过程中，骨骼肌的血流量发生巨大变化，以响应工作量，并在运动后继续偿还运动期间产生的流量债务。因此，静息时的血流量由温度决定，运动时的血流量由肌肉活动的程度决定。
The blood flowing into the limbs supplies skin, subcutaneous tissue, muscle and bone. While blood flow to the bone, nerve and connective tissue of the limb is relatively constant, that to skin and muscle show a great range. The circulation to the skin, and especially that of the extremities, is determined by the need for temperature regulation so that any change in the blood flow in the resting limb occurs as a result of change in the local or ambient temperature. Enormous changes in blood flow to skeletal muscle occur during exercise in response to the workload, and continue afterwards in repayment of the flow debt incurred during exercise. Thus, the resting blood flow is determined by temperature, and exercising blood flow by the degree of muscle activity.
