open (in terms of thermo chemistry) ! It cannot be proved with science yet! BUT WHEN ONE TOUCHES SOMEONE, LOOKS THEM IN THE EYE, so forth one feels the exchange of energy(emotions). they are being effected by the surrounding !
Earthworms have a closed circulatory system. Blood is pumped throughout its body by ringed blood vessels. An open circulatory system is not contained in vessels. In a closed circulatory system oxygen is carried in blood! hope this helps=)
The endocrine system in the human body regulates various bodily functions by producing and releasing hormones that act as chemical messengers to control processes such as growth, metabolism, and reproduction.
Nerves originate in the human body from the brain and spinal cord, which make up the central nervous system, and extend throughout the body to transmit signals and control various functions.
Tendons belong to the musculoskeletal system in the human body.

Your brain is the control center of your body
The 'nucleus' is what controls the cell in a human or animal system of body.
closed circulatory system (double circulatory system)
Earthworms have a closed circulatory system. Blood is pumped throughout its body by ringed blood vessels. An open circulatory system is not contained in vessels. In a closed circulatory system oxygen is carried in blood! hope this helps=)
closed circulatory system.
Yes, the human body uses over 600 muscles to control its motion and to maintain its balance. Muscles are also used for operating most of the body's systems such as the digestive system and the respiratory system (lungs).
The nervous system is the fast-acting control system.
The endocrine system in the human body regulates various bodily functions by producing and releasing hormones that act as chemical messengers to control processes such as growth, metabolism, and reproduction.
Because there is no central nerve system to control the body(the brain).
Nerves originate in the human body from the brain and spinal cord, which make up the central nervous system, and extend throughout the body to transmit signals and control various functions.
