There are two types of blood that flows through our bodies: oxygenated and deoxygenated. Oxygenated blood is the one that is pumped in the left side of the atrium in the heart. As its name tells us, is the one that is highly with oxygen and low in carbon dioxide. Normally a sample of an oxygenated blood will be very bright in red due to the amount of blood cells in it. Deoxygenated blood is the one that is pumped in the right side of the atrium in the heart. This blood is the one that is low in oxygen and high in carbon dioxide. It is also known as the venous blood. Normally a sample of a deoxygenated blood will be darker almost going on blue.
Nitrogen is a fundamental element required during the growth and development of any organism.
- Nitrogen is a fundamental chemical element required to synthesize different biomolecules such as nucleic acids (either DNA or RNA) and proteins.
- Amino acids are the bounding blocks of proteins, whereas nucleotides are the building blocks of nucleic acids, and both contain nitrogen.
- All organisms in their growth phase requires nitrogen in order to synthesize these biomolecules (i.e., nucleic acids and proteins).
In conclusion, Nitrogen is a fundamental element required during the growth and development of any organism.
