Human body systems

There are approximately 79 human anatomy organs, although there is no standard or universally accepted number. ently? they function in groups called systems. An organ system is a group of organs working together for proper functioning of our body. There are eleven systems in the human body: circulatory (blood supply), respiratory (breathing), digestive (digestion and absorption), nervous (sensation and movement), excretory (waste elimination), endocrine (hormonal control), reproductive, lymphatic (defence), skeletal (support), and muscular (movement) systems. The last two are usually combined together into the musculoskeletal system
