Medical educational diagram showing Erythropoiesis steps: a detailed flowchart with coloured cells showing the progression from Pluripotent Stem Cell (dark blue) → BFU-E (blue) → CFU-E (purple) → Proerythroblast (large red nucleus) → Basophilic Erythroblast (dark blue cytoplasm) → Polychromatophilic Erythroblast (mixed pink-blue cytoplasm) → Orthochromatic Erythroblast (pink cytoplasm, small dark nucleus) → Reticulocyte (pink, no nucleus, blue reticular network) → Mature RBC (biconcave red disc). Arrows connecting each stage. Labels for each cell type. On the right side, factors affecting erythropoiesis: EPO, iron, B12, folate, androgens. Clean white background, medical textbook style, bright colours
Medical diagram of Iron Metabolism for medical students: A clear flowchart showing dietary iron absorption and transport. Top: food sources (haem iron 20% absorbed, non-haem iron 2-5% absorbed). Duodenal enterocyte showing DMT-1 transporter, ferroportin export, hepcidin regulation arrow. Blood compartment: transferrin carrying iron (Fe3+) to bone marrow for erythropoiesis. Storage: ferritin in liver, spleen, macrophages. Recycling: macrophages recycling iron from old RBCs. Numbers: total body iron 3-4g, 65% in haemoglobin, 25% storage. Colour coded: orange for absorbed iron, red for haemoglobin iron, green for storage, blue for transport. Clean medical textbook style white background
Medical colour diagram showing Vitamin B12 and Folate metabolism pathway for megaloblastic anaemia. Show: dietary B12 binds to R-binder in stomach, then Intrinsic Factor (IF) secreted by parietal cells, B12-IF complex absorbed in terminal ileum. Folate absorbed in jejunum. Inside cell: both needed for DNA synthesis - methylcobalamin converts homocysteine to methionine, THF to methyl-THF cycle, thymidylate synthesis blocked without B12/folate causing megaloblastic changes. Show blood film with oval macrocytes and hypersegmented neutrophils (5+ lobes). Bone marrow showing large megaloblasts with open chromatin. Bright educational colours, clear labels, white background, MBBS exam style
