Both bone and cartilage are types of connective tissue in the human body that provide structure and support. However, they differ significantly in hardness, flexibility, blood supply, and location.
Bone Cells: Osteocytes.
Cartilage Cells: Chondrocytes.
Bone Matrix: Contains calcium salts (hard).
Cartilage Matrix: Contains chondrin (flexible).
Bone is Vascular; Cartilage is Avascular.
| Feature | Bone | Cartilage |
|---|---|---|
| Hardness | Very hard and rigid | Flexible and elastic |
| Matrix | Calcified (CaCO₃, Ca₃(PO₄)₂) | Non-calcified (chondrin protein) |
| Blood Supply | Highly vascular (has blood vessels) | Avascular (no blood vessels) |
| Cells | Osteocytes | Chondrocytes |
| Regeneration | Can regenerate (heals after fracture) | Very slow regeneration |
| Location | Skeleton (arms, legs, skull) | Nose tip, ear pinna, trachea, joints |
| Lacunae | Present | Present |
Bone is hard and calcified with blood vessels. Cartilage is flexible, non-calcified, and has no blood vessels.
Bone cells are called Osteocytes. Cartilage cells are called Chondrocytes.
Residual Volume (RV) in Lungs
Learn the definition of Residual Volume (RV) in biology. Understand why the lungs never completely empty and the normal RV capacity in humans.
Reticulate Venation — Definition, Examples, and Comparison with Parallel Venation
Reticulate venation is a net-like pattern of veins in dicot leaves like rose and mango. Compare with parallel venation in monocots like banana and wheat.

Retrogressive Metamorphosis — Meaning and Example (Herdmania)
Retrogressive metamorphosis is the change of an advanced free-swimming larva into a simpler, sessile adult, as in ascidians like Herdmania. Learn the process and changes.
What Is the Role of Saliva in Digestion of Food?
Saliva digests starch using salivary amylase (ptyalin), lubricates food to form a bolus, helps swallowing and has antibacterial properties. Full explanation with FAQs.
