Pathway of Blood

Deoxygenated blood enters the right atrium, travels through the tricuspid valve, and enters the right ventricle. On contraction the blood from the right ventricle passes through the pulmonary valve and enters the pulmonary arteries where it travels to the lungs in continuously smaller vessels. It then undergoes gas exchange. The blood then travels into pulmonary venules and into the pulmonary veins, which carry the blood to the left side of the heart. The oxygenated blood enters the left atrium, travels through the mitral valve, and enters the left ventricle. On contraction the blood from the left ventricle passes through the aortic valve and enters the aorta. From the aorta, blood enters arteries, then arterioles, and then capillaries. After gas exchange the blood enters the venules, and then larger veins. The veins empty into the Superior or Inferior Vena Cava and return to the right side of the heart. Right Atrium --TRICUSPID VALVE>> Right Ventricle --PULMONARY VALVE>> Pulmonary Artery -->> Lungs -->> Pulmonary Veins -->> Left Atrium --MITRAL VALVE>> Left Ventricle --AORTIC VALVE>> Aorta -->> Arteries -->> Arterioles -->> Capillaries -->> Venules -->> Veins -->> Venae Cavae -->> Right Atrium

Translation and Progeny Assembly

Translation must occur in order for the virus to reproduce. Requires translocation of the genetic material to the correct location in the cell. Most DNA viruses must go to the nucleus in order to be transcribed to mRNA. mRNA then goes to the cytoplasm where it is translated to proteins. Positive-sense RNA viruses stay in the cytoplasm where it is directly translated to protein by host cell ribosomes. Negative-sense RNA viruses require synthesis of a complementary RNA strand via RNA replicase which can then be translated to form proteins. DNA formed through reverse transcription can be integrated into the host genome. Viral RNA is translated into protein using the ribosomes, tRNA, amino acids, and enzymes of the host cell. Most of these proteins are structural capsid proteins which allow for the creation of new virions. The viral genome can be packaged within the capsid and must be returned to its original form before packaging. It can now invade a new cell
