What is so special about nitrogen in the atmosphere
HACTEHA [7]

Answer:

Firstly, the partial pressure of nitrogen (78%) is crucial to breathing purposes. Without this pressure, the lungs will burst and animals cannot survive.

Secondly, nitrogen is required for the formation of amino acids (building blocks of proteins) and other organic compounds that are necessary for the survival of living organisms. Principally, in the atmosphere, nitrogen is present in the form of molecular nitrogen (N2). N2 is fixed by nitrogen-fixing bacteria that form nitrates and nitrites. These molecules are then used in biochemical processes to produce proteins (amino acids) and other organic compounds. In the absence of nitrogen, these processes could become seize of limited significantly thus affecting life overall.

Thirdly, nitrogen and its derivatives act as greenhouse gases that maintain the Earth's temperature within a range that supports life. Yes, the increased abundance of nitrous oxides is not good because of acid rain and other issues, however, still, the presence of nitrogen is important for life on this planet.

What prevents blood movement from left ventricle to left atrium​
irina1246 [14]

The Mitral valve which is also known as left atrioventricular prevents blood movement from left ventricle to left atrium.

Explanation:

  • Human heart is four chambered.
  • Two of these are receiving chambers known as atria and the other two are distributing chamber known as Ventricles.
  • Atria are superior chambers and ventricles are inferior chambers.
  • The heart has four valves broadly grouped as Atrioventricular valves and Semi lunar valves.
  • Atrioventricular valves allows flow of blood from atria to ventricle. These are tricuspid valve and bicuspid valve.
  • Semi-lunar valves allow blood to pass out of the heart. These include the pulmonary and aortic valves.
  • The pulmonary valve allows blood to flow from right ventricle  to the heart while aortic valve allows blood to flow from left ventricle to the Aorta.
  • The Tricuspid valve located between the right atrium and right ventricle allows blood to flow from right atrium to the right ventricle.
  • The Bicuspid valve ( Mitral valve)  located between the left atrium and left ventricle allows the blood flow from left atria to left ventricle.
  • Valves maintain the unidirectional flow of blood and thus prevent its back flow.
