The back is a body area, not an organ system.
Dorsals refer to the fins located on the back of a fish or marine animal. They help with stability and maneuverability in the water. Dorsal fins can vary in size and shape depending on the species.
The belly side of an animal is called the ventral side or underside. In contrast, the back or top is called the dorsal side.
The lymphatic system is responsible for transporting fat absorbed from the intestine (in the form of chylomicrons) and returning fluid from tissue spaces back into the bloodstream. This system helps maintain fluid balance in the body and plays a crucial role in immune function as well.
The liver has the broadest area for referred pain, as it can cause discomfort in the right shoulder or upper back in addition to the abdominal region. This is due to shared nerve pathways that can cause pain to be felt in areas that are not directly related to the liver itself.
Organisms are the product of evolution. Organisms did not evolve from organ systems, rather, organisms have evolved organ systems to accomplish various specific biological functions. However, if we go back farther, to the evolution of the cell, we find that there are organelles, the mitochondria, which have their own genetics, and which almost certainly evolved originally as independent organisms before entering into a symbiotic relationship with cells. It is speculated that perhaps all the organelles of a cell evolved separately. That is the closest we can come, to an organ system that turns into an organism, although it is really an organelle system.
The back is a body area, not an organ system.
Neurological system. Sensory messages travel along the neural pathway from each organ to the Central Nervous System where action is relayed back to the organ.
The cranium (skull) is the collection of bones that protects the brain, which is the major organ of the nervous system.
They are part of the cardiovascular system.
No, the kidneys are up higher in the back. The vast majority if the time pain in the area you describe is from the muscles in the back. Occasionally other problems with abdominal organs can go there so if the pain is that bad you would be best to see your doctor.
As with most creatures the feeding organ of an earthworm is the mouth. Located behind the mouth is the pharynx which acts as a suction pump; its muscular walls draw food back.
The lymphatic system contains tonsils. Tonsils are small lymphoid organs located at the back of the throat that play a role in the immune system by helping to fight off infections.
Place a scented tart in the top part of the organ (in the orange area inside the pipes), then a unscented tealight in the inside the base from the back side.
Unknown. The development of the organ dates back to before 300 BCE The Greek engineer Ctesibius is given credit for a wind stabilization system using water in approx. 265 BCE.
A fundus examination is a detailed examination of the back of the eye, including the retina and blood vessels. When the fundus is described as unremarkable, it means that no abnormal findings or abnormalities were noted during the examination. This is a positive outcome indicating that the structures at the back of the eye appear normal.
Dorsal or posterior mean back of the body.
The trapezius muscle is part of the muscular system in the human body. It is a large superficial muscle located on the back and neck, and it is responsible for moving and stabilizing the shoulder blades.
