Stretching of the organ by food in the lumen, osmolarity and PH of contents, and the presence of substances and end products of digestion
It responses the light known as positive phototropism which means the stem grows towards the light
The abdominal cavity contains organs such as the kidneys, liver, and intestines that help maintain homeostasis in response to internal and external stimuli. These organs regulate functions such as temperature, fluid balance, and metabolism to keep the body in a stable state.
Stimuli in sense organs are external signals that trigger a response in the sensory receptors, such as light for the eyes, sound waves for the ears, chemicals for taste and smell receptors, pressure for touch receptors, and temperature for thermoreceptors. These stimuli are converted into electrical signals that are then transmitted to the brain for interpretation.
your skin. specifically the dermis
Receptors are groups of specialised cells. They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus. Sense organs contain groups of receptors that respond to specific stimuli.
Special sensory neurons in sense organs that receive stimuli from the external environment.
what governs organs such as the heart,stomach and intestines
i think they belong to the peripheral nervous system (pns)
The nervous system transmits messages from sense organs and the environment to the brain through electrical and chemical signals. Sensory neurons are responsible for detecting stimuli and relaying information to the brain for processing and response.
A daisy plant responds to various stimuli such as light, gravity, touch, and temperature. For example, it bends towards the direction of light for optimal photosynthesis and growth and closes its petals during the night or in response to touch to protect its reproductive organs. These responses help the daisy plant survive and thrive in its environment.
In order for the body to respond to external stimuli, it must first receive the stimuli through the sensory organs. These organs, such as the eyes, ears, skin, nose, and tongue, detect various forms of stimuli, including light, sound, touch, taste, and smell. The sensory information is then transmitted to the brain for processing, allowing the body to react appropriately.
The regulation in the endocrine system is mainly achieved through feedback mechanisms involving hormones. Negative feedback loops help maintain homeostasis by sensing and responding to changes in hormone levels. Hormones are released in response to specific signals and act on target cells to elicit a physiological response.
