There are 4 parts of the Circulatory or Cardiovascular System. The main part is the Circulatory/Cardiovascular System (heart, blood vessels, blood.) And there are 3 sub-systems. The Immune System including the white blood cells, the Lymphatic System including the tonsils, thymus, liver, spleen, appendix, lymph nodes, & lymph vessels, and the Urinary System including the kidneys, ureters, bladder, & urethra.
There are two: the digestive system and the cardiovascular system.
The respiratory system and the circulatory (cardiovascular) system.
1. Respiratory system 2. Cardiovascular system
I believe it's the cardiovascular system and the respiratory system.
The cardiovascular and respiratory systems are two different systems in the body, though they are closely related. The cardiovascular system is made up of the heart, blood vessels, and blood. The respiratory system is made up of the trachea, bronchii, alveoli, and the lungs.
cardiovascular system mainly, which will help with your aerobic endurance (also, depending on your situation, anerobic).Also, your muscular system. :)
The systems controlling the whole human system are the vital systems in the body...they are:Airway&Breathing > Respiratory SystemCirculation >CardioVascular systemAbove two system form the ABC of Resucitation & for Maintainance of LifeThe Integrity & functional preservation of Central Nervous System are maintained by the above two systems.Preservation of Central Nervous System is the basis for a gud quality of life.
The main two are the skeletal system and the muscular system however, the muscles can't do anything without the nervous system and the cardiovascular system.
The nervous system and the endocrine system are the two major regulatory systems in the body.
The two coordination systems of the body are the nervous systems and the endocrine sytems, which enable all parts of the body to work together as one.
The Nervous System and the Endocrine System are the two body systems that regulate homeostasis.
Digestive and respitory systems
