1. Motor system: bones, cartilage, joints, skeletal muscles (2) Nervous system: divided into central nervous system and peripheral nervous system.The central nervous system includes the brain and spinal cord. The peripheral nervous system includes cranial nerves, spinal nerves and vegetative nerves.
2. Digestive system: Organs related to digestion and feeding include: oral cavity, pharynx, esophagus, stomach, small intestine, large intestine, anus, and salivary glands, gastric glands, intestinal glands, pancreas, liver, etc., so they are called digestive organs. These digestive organs work together to complete the digestion of food and the absorption of nutrients.
3. The earliest animals to appear in the eight major systems are flat animals. In this kind of animal, the digestive system, excretory system, nervous system and reproductive system appear. The phylk phyla is the second animal with eight major systems, at which time the circulatory system and the muscle system appear.
4. Respiratory system, digestive system, urinary system, reproductive system II. Animals mainly include vertebrates and invertebrates.Vertebrates have eight major systems. Invertebrates are not necessarily.
Animals are composed of eight major systems. The organ you mentioned is the system that makes up. ( 1) Motor system: bones, cartilage, joints, skeletal muscles (2) Nervous system: divided into central nervous system and peripheral nervous system. The central nervous system includes the brain and spinal cord. The peripheral nervous system includes cranial nerves, spinal nerves and vegetative nerves.
The circulatory system is a system composed of the body fluids (including intracellular fluids, plasma, lymph and tissue fluids) of organisms and their circulating pipes. After the formation of the heart in animals, the circulatory system is divided into two major parts: the heart and the blood vessels, which is called the cardiovascular system.
Respiratory system, digestive system, urinary system, reproductive system II Animals mainly include vertebrates and invertebrates. Vertebrates have eight major systems. Invertebrates are not necessarily.
There are eight major systems, including the reproductive system, the urinary system, the respiratory system and the digestive system. Reproductive system: The reproductive system is the system responsible for producing germ cells and reproducing offspring. Higher animals and the human body have different reproductive organs, such as testicles, ovaries, etc., which produce sperm and eggs respectively.

4. The eight major systems of animals are the digestive system, nervous system, respiratory system, circulatory system, motor system, endocrine system, urinary system and reproductive system.
5, the eight major systems in the human body of higher animals include: motor system, nervous system, endocrine system, circulatory system, respiratory system, digestive system, urinary system and reproductive system. These systems can be memorized in the following ways: Write a song secret: the inner and outer division of the motor nerves, the front and rear movement of breathing and digestion.

The eight major systems of animals are: digestive system: the organs related to digestion and feeding include: oral cavity, pharynx, esophagus, stomach, small intestine, large intestine, anus, and salivary glands, gastric glands, intestinal glands, pancreas, liver, etc., so they are called digestive organs.
3. Forest ecosystem, forests not only play an important role in water storage, but also play an important role in maintaining water and soil. Grassland ecosystem, grassland ecosystem is distributed in arid areas, and the annual precipitation is very small, resulting in many species of animals and plants.
