Blood always flows through the system in the same pattern: coming from the body, passing through the right side of heart, then out to the lungs to receive oxygen, then passing back through the left side of the heart and then traveling out to the body. Heart valves help to keep the blood flowing properly to each important destination of the circulation journey.

Answer:
The events of protein synthesis are simple- First of all, protein synthesis is the process for which cells make proteins. Protein synthesis occurs in only two stages, transcription and translation.
Transcription-
Transcription is the transfer of genetic instructions in DNA and mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
Translation-
Translation occurs at the ribosome, which consists of rRNA and proteins. During translation, the genetic code in mRNA is read and is used to make protein.
Explanation:
The two processes (transcription and translation ) are pretty much summed up by the 'central dogma of molecular biology' which goes- DNA → RNA → Protein.
