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).
