The two external controls of the circulatory system is the house.
The respiratory system and the circulatory system
None. Your blood and the circulatory system is internal. Clothing is external, barring accidents the two have no contact.
The two main part of circulatory system are hearth and Arteries
The respiratory system and the circulatory (cardiovascular) system.

Some species, like insects, have an open circulatory system
Blood and oxygen are transported by the circulatory system.
The skeletal system works with the muscular system to provide structure and support for movement. Additionally, the nervous system controls muscle movement by sending signals from the brain to the muscles.
The circulatory system can be considered as composed of two parts: The main components of the human circulatory system are the heart, the blood, by tissues undergoing high metabolism, as they require increased levels of oxygen.
cardiovascular system and respiratory system
The sinoatrial (SA) node of the heart serves as its pacemaker, and receives nerve input from the nervous system in order to initiate the "pumping" activity that controls the circulatory system. In addition, muscles of blood vessels can expand and contract from signals from the autonomic (sympathetic and parasympathetic) nervous system in order to control blood pressure.
The organs of the circulatory system include the blood, blood vessels, and heart. The blood is an unusual organ in that it is a liquid.
