Calves, Pulmonary Embolism, and Quick Thinking (S01E08)

The liver is suffering from a decline in health due to rising rates of smoking and alcohol use. Its cells are in poor condition, overwhelmed by excess fat that has hindered the organ's functions. Amidst this troubling situation, Red Blood Cell (AA2153) finds himself puzzled but is called upon by his fellow Red Blood Cells to assist in oxygen transport, as their numbers have dwindled. With no time to rest and the calves in a fragile state, they resolve to deliver much-needed oxygen to a deep vein that is lacking in vital supplies.
