• increased calcium

• increased blood flow

• more synovial fluid

Which is a response of synovial fluid to exercise

• increased temperature

• Synovial flui

Which one is a response of the synovial joint in exercise

• lower vitamin D

• increased calcium

• decreased viscosity

• reduced synovial fluid

What do osteoblasts do

• make vitamin D
