<span> How does pulmonary circulation work? In my example below, we will start with the blood not reaching the heart yet. The heart beats around 75 beats a minute. Deoxygenated blood is in the veins, going to the heart. Note that veins will always carry deoxygenated blood, excluding the pulmonary veins. The deoxygenated blood goes into the heart through the superior or inferior vena cava, and goes into the right atrium. It then gets pumped into the right ventricle, and gets pumped through the pulmonary arteries to the lungs to get oxygenated. The blood, now oxygenated, comes back to the heart through the pulmonary veins, into the left atrium. The blood gets pumped from the left atrium to the left ventricle, where it gets pumped through the aorta to all of the body systems. The red blood cells travel through capillaries, which is where most of the gas exchange occurs between body cells and red blood cells. Red blood cells have no nuclei. When the red blood cells are no longer red, but blue due to lack of oxygen, they go back to the heart to get pumped to the lungs, and enter the heart through the superior or inferior vena cava. The cycle starts over. Just like the veins, arteries always carry oxygenated blood, excluding the pulmonary arteries. Also, the right side of the heart will have deoxygenated blood, or blue blood, and the left side of the heart will have oxygenated blood. </span>

Answer:</h2>
<h2>
_____________________________________</h2><h3>MECHANISM:</h3>
Following diagram shows the transport of protein.
1- The nucleus is involved in teh formation of mRNA which is used to send message to the ribosome about what kind of protein is used to synthesize
2- and 3- Endoplasmic Reticulum(ER), Rough ER has the ribosomes on their surface, which are involved in teh formation of protein.
4- They are the vesicles from the RER
5- It is the Golgi body or Golgi complex or golgi apparatus or simply Dictyosomes. They are used in the packaging of the protein, gives the protein finishing touch before they move out from the cell. They like ER has canalicular system with sacs but they are parallel arranged, flattened membrane bounded with lack of ribosomes. They have two faces. One is receiving face which receives the vesicles from the Endoplasmic reticulum called cis face. The other is shipping face which releases packaged protein into the cytoplasm ready to go outside from the cell.
6and 7- They are the vesicles from the golgi bodies.
8- Vesicle diffuses with the cell membrane through which the protein is moving out from the cell, the process called exocytosis.
