Human body is functioning through following body systems. They are:
1. Skeletal system, 2. Muscular system, 3. Digestive system, 4. Circulatory system
5. Respiratory system, 6. Nervous system, 7. Excretory (urinary) system, 8. Endocrine system.
There are also reproductive, lymphatic and integumentary (skin) systems.
My favorite animal is a horse, and it has the same body systems like all higher mammals.
Muscular system (skeletal muscles, smooth muscles and cardiac muscles);
Skeletal system: All mammals have skeletal system, it is necessary to support the body (for example, skeleton, exoskeleton or shell);
Circulatory system (arteries, veins and capillaries)
Respiratory system (nose, lungs, and trachea);
Nervous system. (the central nervous system (the brain and spinal cord), the peripheral nervous system and the autonomic nervous system);
Excretory (urinary) system (kidneys, bladder and urethras);
Endocrine system – hormones and glands (the thyroid, pancreases, parathyroid adrenal, pituitary, pineal body, thymus, testes and ovaries);
Digestive System (stomach, pancreas liver and intestine);
Yes, the animals have all eight systems, such as skeletal system, muscular system, circulatory system, respiratory system, digestive system, excretory system, nervous system and endocrine system. Hoarse also has reproductive, lymphatic and integumentary (skin) systems.
