Max_concurrent_shard_request per node

I have read the elasticsearch document search API and understand Max_concurrent_shard_request is used to control the maximum number of concurrent shard requests the search API will execute per node for the (per?) request.
I want to know is there any other limit for concurrent shard request per node? for example if I send 10 parallel request to elasticsearch with Max_concurrent_shard_request=5 , the node will handle 50 shards request simultaneously or the node also have other limits in this situation and queue the requests?

Thanks for any guidance.
