Endocrine System The foundations of the endocrine system are the hormones and glands. As the body's chemical messengers, hormones transfer information and instructions from one set of cells to another. Although many different hormones circulate throughout the bloodstream, each one affects only the cells that are genetically programmed to receive and respond to its message. Hormone levels can be influenced by factors such as stress, infection, and changes in the balance of fluid and minerals in blood.

A gland is a group of cells that produces and secretes, or gives off, chemicals. A gland selects and removes materials from the blood, processes them, and secretes the finished chemical product for use somewhere in the body.

Some types of glands release their secretions in specific areas. For instance, exocrine glands, such as the sweat and salivary glands, release secretions in the skin or inside of the mouth. Endocrine glands, on the other hand, release more than 20 major hormones directly into the bloodstream where they can be transported to cells in other parts of the body.

Reflection The endocrine system has a variety of endocrine glands in different sizes and shapes located in different parts of the body. Without your endocrine glands and the hormones they release your cells wouldn't know when to do important things, also you have to know a lot about the endocrine system and can help treat people with hormone problems.

Sensory System The Sensory system is a part of the nervous system that consists of sensory receptors, neural pathways, and those parts of the brain responsible for processing the information. Specific sensory systems are those for somatic sensation, vision, olfaction, taste and hearing.

Sensory systems code for four aspects of a stimulus; type (modality), intensity, location, and duration

Reflection I can said that the sensory system is a part of the nervous system responsible for processing sensory information commonly recognized sensory systems are those for vision, auditory (hearing), somatic sensation (touch), gustatory (taste), olfaction (smell)and vestibular(balance/movement).
