The olfactory epithelium, located high up in the nasal cavity, contains specialized cells responsible for detecting odors. This region receives more of the smell as air passes over it during breathing.
What is the smallest complete living unit of the body
This phenomenon is known as a reflex arc or a reflex action. It occurs when a stimulus, such as touching something hot, triggers a sensory nerve that sends a signal to the spinal cord, which then quickly sends a response through motor nerves to another part of the body, often resulting in an involuntary movement like pulling away from the stimulus. This process helps protect the body from harm by allowing for rapid reactions without the need for conscious thought.
The brain
Effector organ is a part of the body that responds to a stimulus and a stimulus is a change in the environment that is detected by a receptor. And is a receptor is a nerve cell that detects a stimulus.
You will have to use your finger on your ear to determine which part of the ear receives a stimulus
ThalamusIf you are referring to outside stimulus that are sensory messages, all stimuli, except smell, go to the thalamus in the brain which is then relayed to the cerebral cortex.
The nervous system is made up of three parts: the receptor, the decider, and the effector. The receptor receives an stimulus and creates an electric impulse to be sent to the brain. The brain receives this impulse and decides what to do in order to react to the stimulus. Your brain then makes a decision and sends out an electric impulse to the effector which moves the muscle or activates a gland in your body which is a reaction to the stimulus.
your body is reacting to a stimulus that is coming from your nose hope i helped :)

The right atrium.
it receives and delivers blood to the other part of the bods(body)y
The right atrium from the body and the left atrium from the lungs.
What is the smallest complete living unit of the body
The smell receptors in the human body are located in the olfactory epithelium, which is found in the upper part of the nasal cavity.
This phenomenon is known as a reflex arc or a reflex action. It occurs when a stimulus, such as touching something hot, triggers a sensory nerve that sends a signal to the spinal cord, which then quickly sends a response through motor nerves to another part of the body, often resulting in an involuntary movement like pulling away from the stimulus.
