Final answer:
Synovial joints (SJ) are involved in systemic circulation, which delivers nutrients and oxygen to these joints and other organs, including the stomach, which is connected to the spleen via the gastrosplenic ligament.
Step-by-step explanation:
The question 'SJ connected with which organs?' pertains to the biological connections of synovial joints (SJ). Synovial joints are the only joints in the body that have a space between the adjoining bones, which allows for greater movement. They are connected to various organs through the systemic circulation, which is the flow of blood away from the heart to all other parts of the body, including the brain, liver, kidneys, stomach, and limbs before returning to the heart. For instance, the spleen is attached to the lateral border of the stomach via the gastrosplenic ligament and plays a significant role in filtering blood and immune responses. Moreover, during systemic circulation, the heart, through its contractions andblood vessels like the superior vena cava, ensures the delivery of oxygen and nutrients to these joints and the removal of waste products.
