In biological terms, an internal and external stimuli are distinguishable by the source. For instance, hunger triggers the need to eat. This is an internal stimuli, as the body is stating it needs food. An external stimuli would be feeling the pinch of the needle when donating blood, or feeling the effects of the sun in the form of sunburn.
External stimuli comes from the environment outside an organism, such as temperature. While internal stimuli comes from within an organism, such as the level of glucose sugar in your blood.

True. Hunger is internal, a voice is external.
When a mouse runs for cover in the presence of a cat the cat is an example of an external stimulus. Mice have an innate fear of cats, but the cat itself would be an external stimuli.
The external stimuli involved are as follows: the eyes see the warm coloring of peach, the nose smells the scent of the ripe peach, and your salivary glands start releasing saliva to help dissolve the peach itself. The internal stimuli is mainly your brain, which processes all of this information that the other senses are sending, and sends, for lack of a better word, "spark" to your arm and hand so you can bring the peach toward your mouth and eat it.
This is a very broad question, so a broad answer would be: Internal stimuli will most commonly be automatic reflexes triggered by external stimuli. Example, a drop in temp. will start shivering, cold is felt on the skin a nerve pathway is initiated to the brain triggering follicle stimulation and muscle spasming. Eating more acidic foods (external) will result in the organism producing more bicarbonate to neutralise the acid (internal).

Nervous System
Internal stimuli is unconscious stimuli that occurs without conscious thought. External stimuli occurs from outside sources that procur conscious thought.

True. Hunger is internal, a voice is external.
Stimuli are composed of two types: The Internal Stimuli and External Stimuli. Under internal stimuli are homeostatic imbalances and blood pressure. On the other hand, external stimuli are vision, touch and pain, taste, smell, equilibrium and sound.
how can respiatory system respond to internal and external stimuli
Internal and external stimuli affect cells
reflexes
They are receptors.
This is called sensation.
