they are parts of the circulatory sytem


to say the veins& capillaries can be quite confusing in grouping them in the circulatory system & endocrine system .The vessels carry out secondary endocrine functions such as;transporting hormones transported by the endocrine system to and from the cells in the body, thus the blood vessels are only included in carrying secondary functions in the endocrine, excretory & respiratory system.They carry out primary functions in the circulatory system.
