Regulatory Systems
The human body has several regulatory systems that work together to maintain balance and homeostasis. These systems include the nervous system, endocrine system, and immune system.
Nervous System
The nervous system is responsible for sending and receiving signals throughout the body. It consists of the brain, spinal cord, and network of nerves. The nervous system helps regulate various bodily functions, including movement, sensation, and internal organ activity.
Endocrine System
The endocrine system is made up of glands that produce and secrete hormones, which regulate various processes such as metabolism, growth, and reproduction. The glands of the endocrine system include the pituitary gland, thyroid gland, adrenal glands, and pancreas.
Immune System
The immune system is the body's defense against pathogens and foreign invaders. It is made up of a network of cells, tissues, and organs that work together to identify and destroy harmful substances. The immune system also plays a role in regulating inflammation and healing processes.
