nervous system
The nervous system controls other organ systems through the coordination and regulation of body functions. It receives and sends signals to different parts of the body to maintain homeostasis and respond to internal and external stimuli.
The brain controls water balance, body temperature, and the endocrine system.
It is an organ. The heart belongs to cardio-vasculary organ system.
the endocrine system
The liver. It is also the heaviest internal organ as well. The liver is part of the digestive system. Hope this helped! :)
The largest internal part in your body well.................let's see...............when people mean part, sometimes that can mean an organ or a body part like a leg, arm, or head. The biggest internal organ in your body is your heart. The biggest internal part would probably be your muscular system or skeletal system.
The nervous system controls the body's reactions to outside stimuli and internal changes by sending electrical signals through neurons. These signals help coordinate actions like movement, sensation, and organ function.
We can say all the systems controls each other but the whole body is controlled by Nervous system and Endocrine System. The Endocrine System by hormones controls the excretory system and controls the nervous system during emergency by releasing Adrenaline hormone. So all organ systems controls each other.
The brain is the organ that controls all systems of the body. It receives and processes signals from the body, allowing it to coordinate functions, regulate processes, and respond to changes in the environment to maintain homeostasis.
The liver is the most heaviest organ in the human body; It is also the largest internal organ.
The skin is an organ of the integumentary system. It helps in giving body shape and protect internal organs so organ of defence, and structure
Internal organ systems: Pelvic system, digestive system, urinary system, skeleto-muscular system.
