Answer:

Blood is received from the head and forelimbs by the precaval vein (anterior or superior vena cava), whereas blood is drained from the trunk and hindlimbs by the postcaval vein (posterior or inferior vena cava).

Explanation:

What is precaval vein:

• The external jugular, internal jugular, subclavian, and anterior intercostal veins make up each precaval.
• Blood is collected from the head, mouth, and jaw muscles in the external jugular.
• Blood is collected from the neck and brain muscles by the internal jugular.
• The external jugular is connected to the subclavian vein, which collects blood from the shoulders and forelimbs.
• The right auricle receives blood from both the anterior right and left precavals.

What is postcaval vein:

• The inferior vein, also known as the postcaval vein, transports deoxygenated blood from the lower half and middle of the body to the atrium.
• Hepatic veins, inferior phrenic vein, right suprarenal vein, renal veins, right gonadal vein, lumbar veins, and common iliac veins are the veins that connect to the inferior vena cava.
• These veins discharge into the inferior vena cava directly.
