OK class, we are going to be learning about the voyage of a red blood cell.
Red Blood Cells are the most abundant of the blood cells.
Red blood cells are formed in the red marrow.
Your assignment is to do some research on the journey of a red blood cell and report back to me.
Red blood cells are made with Hemoglobin so that it can carry oxygen throughout the body. Blood goes from the veins to the capillaries and finally the arteries. The arteries carry oxygenated blood out from the heart. The biggest artery is called the aorta.
Then, from the lungs, the cell travels to the Alveoi. Finally, the cell goes through called cellular respiration.
From the heart, the red blood cell is pumped into the lungs.
After cellular respiration, the red blood cell goes into oxygenated blood. Afterward, the cell could either go into pulmonary circulation or systemic circulation. During pulmonary circulation, the cell goes to the lungs to the heart to give the heart oxygen. Systemic circulation carries the blood to the rest of the body through the arteries.
Cellular respiration is a process where the blood cell exchanges its carbon dioxide for oxygen.
Once the red cell reaches the capillaries, it release oxygen and takes the carbon dioxide. It travels through the veins to the heart and lungs.
Then the process repeats itself.
