Medical education color diagram showing wound healing by primary and secondary intention side by side. Left side: Primary intention (clean surgical wound) showing 4 steps - Initial incision with blood clot, Day 3 acute inflammation with neutrophils, Day 5 granulation tissue and epithelial bridging, Week 4 scar maturation. Right side: Secondary intention (large gaping wound) showing the same timeline but with larger granulation tissue, wound contraction by myofibroblasts, and slower epithelialization. Use bright educational colors: red for blood/vessels, blue for neutrophils, pink for granulation tissue, yellow for fibrin clot, green labels. Include arrows and stage labels. Medical textbook style diagram.

Medical education color diagram of fracture healing stages. Show 6 sequential steps in a horizontal timeline: 1) Fracture with hematoma formation (red blood clot between broken bone ends), 2) Procallus/soft callus - granulation tissue invasion and cartilage formation (pink-purple), 3) Hard bony callus - woven bone formation (yellow-orange), 4) Remodeling - lamellar bone replacing woven bone (beige). Include labeled arrows, bone cross-sections showing cortex and medullary canal, osteoblasts (blue), osteoclasts (red), chondrocytes (purple), cartilage matrix (green). Bright educational medical diagram style with clear color coding and labels.

Central circle labeled "Trisomy 21 (47 chromosomes)" with colored branches showing: 1) Facial features - flat face, epicanthal folds, low-set ears (draw simple face), 2) Karyotype showing 3 copies of chromosome 21, 3) Cardiac defects - ASD, VSD, AV canal, 4) Mental features - intellectual disability IQ 25-50, 5) GI - duodenal atresia, Hirschsprung disease, 6) Other - Brushfield spots, Simian crease, atlantoaxial instability, increased risk of leukemia and Alzheimer disease. Color code each system differently. Include meiotic non-disjunction diagram. Bright, clear educational style.

Medical education color diagram showing pathogenesis of obesity and its complications. Center: Obese human silhouette (large). Surrounding arrows pointing outward to complications labeled in colored boxes: Metabolic syndrome (red), Type 2 Diabetes - insulin resistance (orange), Cardiovascular disease - atherosclerosis (dark red), Hypertension (purple), Sleep apnea (blue), NAFLD/NASH (green), Osteoarthritis (brown), Cancers - breast endometrial colon (pink), Gallstones (yellow), DVT/PE (maroon). Inward arrows showing causes: genetics/leptin resistance, high calorie diet, sedentary lifestyle, hypothalamic dysregulation. Include leptin-adiponectin imbalance diagram.

Medical education color diagram comparing Kwashiorkor and Marasmus (SAM - Severe Acute Malnutrition). Left side Kwashiorkor: Child silhouette with edema (pitting edema legs, ascites, moon face), skin lesions, hair changes (flag sign), fatty liver, low albumin, adequate calories but protein deficiency. Right side Marasmus: Emaciated child, muscle wasting, loss of subcutaneous fat, wrinkled skin, no edema, both protein and calorie deficiency. Center: pathogenesis arrows showing albumin, edema mechanism, cortisol, growth hormone. Color code: blue for edema, yellow for fatty liver, red for muscle wasting, green for skin changes. Clear labeled educational diagram.
