Final answer:
False. Absorbed foodstuffs from the intestines are not first sent through the spleen, but rather go through the hepatic portal system and the liver before circulating back to the heart.
Step-by-step explanation:
False. Not all absorbed foodstuffs from the intestines are sent through the spleen before being dumped into the general circulation. Instead, the absorbed nutrients from the small intestine are first drained into the hepatic portal system, a network of veins that transports the blood into the liver. In the liver, the nutrients are either processed or stored for later use before the blood circulates back to the heart.
