Stomach, spleen, bile duct system, small intestines, kidneys, bladder, etc. – the remainder of the abdominal organs found in the fetal pig are basically the same as found in humans. Thymus – the thymus is found in the same areas in pigs as in humans.
What is the function of the thymus gland?
The thymus makes white blood cells called T lymphocytes (also called T cells). These are an important part of the body’s immune system, which helps us to fight infection. The thymus produces all our T cells before we become teenagers.
Why does a vasectomy not affect urine flow in pigs?
