Bones are rich in blood supply

Answer 2

Answer:

CARTILAGE -

• The matrix also called as intracellular material is solid.
• The matrix is also piliable which is due to the presence of chondroitin salts and it resists compression.
• The cartilage cells are called chondrocytes.
• The chondrocytes are enclosed in small cavities within the matrix secreted by them.
• Mostly, the cartilages in vertebrate embryos are replaced by bones in adults.
• Cartilage is present in the tip of nose, outer ear, joints in the vertebral column, limbs and hands in adults.

BONE -

• It had hard and non piliable matrix.
• The matrix is said to be rich in calcium salts.
• The calcium salts make bones strong.
• The bone cells are called osteocytes.
• The bone cells are seen in space is called lacunae.
• The functions of bone include providing structural frame to the body, supporting and protecting tissues and organs and taking part in locomotion and movement.
• The blood cells are produced in bone marrow.
• Limb bones help in weight bearing.
