Fins belong to the aquatic locomotion system of fish and other marine animals. They are specialized structures that provide stability, maneuverability, and propulsion in water. Composed of a bony or cartilaginous skeleton covered by skin, fins help organisms navigate their aquatic environment efficiently.
The eyes belong to the Nervous system.
The immune system
The Circulatory System
the bob system
The musculoskeletal system, specifically the hand.
Penguins know who they belong to because of there fins and by the color of there stomachs.
They belong to the nervous system
The fins act to distribute heat from the system or absorb heat into the system from the surrounding air depending on the location and purpose of the coils carrying the coolant. In a heat pump system, the fins function depends on which way the heat is being transferred. For an air conditioner, the indoor fins bring heat to the coolant from the air and expel heat at the outdoor fins into the air
The kidneys belong to the excretory system.
Veins belong to the circulatory system, because they transport blood there for they belong to the circulatory system.
they have a propulsion system
The eyes belong to the Nervous system.
An air cooled system uses cooling fins, in which air is either blown past these fins by a flywheel or a cooling fan, this air that is blown into these fins carries residual heat away from the cylinder jug.
Efficiency drops dramatically depending on how badly bent the fins are.
Arteries and veins belong to the cardiovascular system.
The lungs belong to the Respiratory System.
Hagfish. Hagfish are primitive marine animals that belong to the class Myxini. They are known for their lack of jaws and paired fins.
