hormones
Both hormones and secretions of the nervous system are chemical messengers that help regulate various bodily functions. Hormones are produced by glands and released into the bloodstream to target distant organs, while nervous system secretions like neurotransmitters act locally at synapses to transmit signals between neurons. Both systems work together to maintain homeostasis and coordinate responses to internal and external stimuli.

Hormones act as chemical triggers and messengers for cell processes. They are secreted by endocrine glands and travel through the bloodstream to target cells, where they can regulate various physiological functions.
steroids
Glands release various substances, primarily hormones, enzymes, and other secretions. Hormones are chemical messengers that regulate body functions, such as growth, metabolism, and mood. Enzymes aid in digestion and metabolic processes, while other secretions can include mucus, sweat, and saliva, which play roles in protection, lubrication, and temperature regulation. Together, these substances help maintain homeostasis and support overall bodily functions.

Chemical digestion begins in the mouth with the secretion of saliva from three pairs of salivary glands. Saliva contains the digestive enzyme salivary amylase.
The digestive juices are the secretions of the digestive tract that break down food. They include saliva, gastric juice, pancreatic juice, bile, and intestinal juice. The digestive juices are secreted by different organs, vary widely in chemical composition, and play different roles in the digestive process. Each is constantly produced by the body in small amounts, but the presence of food as it passes through the digestive tract causes increased production and secretion.

Saliva moistens food particles, helps bind them, and begins the chemical digestion of carbohydrates. Also solvent, it dissolves foods so they can be tasted.

The digestive main functions are: ingestion (the taking of the food via the mouth. digestion- the mechanical and chemical break down of food by chewing and enzymes. absorption- food passes through the intestinal wall into the blood system and elimination- the removal of indigested waste
