If you mean what does a dendrite DO, it receives impulsesfrom other neurons via synapses.
If you mean something else, you may need to form your question better.
For instance, what do you mean by 'interaction'? Are you perhaps asking what happens at a dendritic spine as neurotransmitters diffuse to it?
If so, then what happens is that sodium-ion gates are opened, allowing sodium ions in, starting a graded impulse propagating toward the axon hillock, where it may summate to cause the action potential to fire in the axon.
To "connect" two neurons, (or a neuron and a muscle cell), by providing a space between an axon terminal of one neuron and a dendrite of another neuron (or a muscle cell), so neurotransmitters that are released by an axon terminal can diffuse across that space to reach the dendrite (or muscle cell) and either initiate the possibility of the second neuron to fire or cause a muscle cell to contract.
dendrite
dendrite. Dendrites receive signals from other neurons and transmit these signals to the cell body for processing.
The axon sending a neuron is separated from the dendrite of the receiving neuron by a synapse. This small gap allows for the transmission of neurotransmitters, which are chemical signals that facilitate communication between neurons. When an electrical impulse reaches the end of the axon, neurotransmitters are released into the synapse and bind to receptors on the dendrite of the receiving neuron, allowing the signal to be propagated.
The cell body, or soma, of a neuron contains all of the organelles, including the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and others. This is where most of the metabolic functions of the cell occur.
Receptive region of neuron-- bear receptors for neurotransmitters released by other neurons.
the longest dendrite is I don't know this /;[
When a message gets sent to a neuron from the dendrite it goes through the cell body to the tip of the dendrite where it leaps to the next dendrite.

The part of the neuron that carries impulses towards the cell body is called the dendrite.
