Explanation / Answer

The hepatic portal vein connects the capillary beds of the small intestine to a capillary bed in the liver.

Blood in the hepatic portal vein is rich in glucose, amino acids, and nutrients absorbed by the digestive tract, but is oxygen poor.

The liver stores glucose as glycogen, and amino acids are either used to manufacture proteins, or stored as well.

The liver purifies the blood, ridding it of toxins and pathogens that have entered the body via intestinal capillaries.

After filtration in the liver, blood is returned to the interior vena cava via the hepatic vein.

Cardiovascular disease, the leading cause of early death in Western countries, includes hypertension, or high blood pressure, and , thromboembolismor plaques inside blood vessels.

These issues can lead to heart attack or stroke, or even the bursting of a blood vessel called the aneurysm.

Though aspects of cardiovascular disease can be genetic, other factors are at play as well, lifestyle choices like diet, exercise, and activities such as smoking also influence cardiovascular health.

Plaque in the blood vessels can find their beginnings in bacterial or viral infections such as those associated with atherosclerosis or ulcers.
