<span>Pulmonary vein
Pulmonary circulation is the movement of blood starting from the heart, where deoxygenated, or carbon dioxide-filled, blood leaves from the right ventricle and through the pulmonary valve, then into the left and right pulmonary arteries and arrives at the lungs. During the process of respiration, the carbon dioxide is released and oxygen is added to the blood. </span>
The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.
Answer:
Explanation:
The non-coding DNA sequences forms the part of the organism's DNA. It is the part of the human genome which does not encode for any protein sequence. Some of the non-coding DNA may be transcribed into into any of the functional non-coding RNA molecules such as ribosomal RNA, transfer RNA and regulatory RNA. Other functions of the non-coding DNA involve translational and transcriptional regulation of the protein coding sequences, origin of DNA replication process, scaffold attachment, telomeres and centromeres.
