Other than the previous block hash and nonce data, which elements of a block are concatenated in order to be hashed?

The whole block header is hashed including:
- Block version number
- 256-bit hash of the previous block header
- 256-bit hash based on all of the transactions in the block (hashMerkleRoot)
- the current timestamp as seconds since 1970-01-01T00:00 UTC
- Bits (updated when he difficulty is adjusted)
- Nonce
