The brain, heart, liver, intestinal/digestive system, etc. are the most important organs. There is a reason they are called "vital" organs. The lesser-known organs with funny-sounding names are generally the least important ones. (Pancreas, Spleen, etc.)
They're all vital in their own way.
* Heart/lungs function can be replaced by a bypass machine. * Musculoskeletal is unnecessary if you don't want to 'move' but this would include any form of communication at all making one a prison in one's body. * Urological system can be replaced by dialysis and catheters etc. * Reproductive system is necessary to reproduce without which species would die out, but we could get by day-to-day fine without it. * Skin is vital to maintain fluid balance (we'd dry out and die without it) and to prevent infection. * Gastrointestinal can be replaced by nutrition straight into the blood. * Endocrine system is really essential and difficult to completely replace. * Nervous system - I suppose we would cease to 'be' without it and it wouldn't matter about the other systems. They're all vital in their own way.

Pulmonary and cardiovascular are the most vital. Without oxygen getting to the tissues death ensues within several minutes.
The nervous system (brain).
The nervous system and the endocrine system are the two major regulatory systems in the body.
The Nervous System and the Endocrine System are the two body systems that regulate homeostasis.
doodoo head
All organ systems regulate homeostasis for the body. I'm not sure which two are the most important. For example, the Regulatory System (lungs, trachea, etc.) regulate homeostasis by breathing. The Excretory System (Kidney, bladder, etc.) regulates homeostasis by removing wastes.
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.
It is necessary to have multiple organs because without all of our organs we would not be able to operate properly.
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
the respiratory and circulatory systems
there are way more than two, but i think you mean the endocrine and nervous systems
The nervous and endocrine systems are the two systems responsible for controlling behavior.
More than two do: 1. the integumentry system (skin) 2. the urinary system * 3. the respiratory system * 4. the digestive system * most important
the other systems are not affected
The body is regulated by the nervous system and the endocrine system.
The glandular organ the pancreas is part of the digestive andendocrine systems.
