Superior and Inferior Vena Cava
The vessel that carries deoxygenated blood from the brain back to the right side of the heart is the jugular vein. Specifically, the internal jugular vein collects blood from the brain and neck and drains it into the brachiocephalic vein, which then empties into the superior vena cava. This blood ultimately returns to the right atrium of the heart.

No. The gonads are drained by the gonadal veins. The left gonadal vein empties into the left renal vein (and further into the inferior vena cava) whereas the right gonadal vein empties directly into the inferior vena cava.

The coronary sinus is the main vessel that drains oxygen-depleted blood from the myocardium into the right atrium. It collects blood from the cardiac veins that run throughout the heart muscle and then empties into the right atrium of the heart.
coronary sinus. It is a vein located on the heart's surface that collects deoxygenated blood from the coronary circulation and returns it to the right atrium.
The venous drainage of the kidney primarily occurs through the renal veins, which collect deoxygenated blood from the renal cortex and medulla. Each kidney has its own renal vein that drains into the inferior vena cava on the right side and into the left renal vein on the left side. The left renal vein also receives blood from the left gonadal vein and lumbar veins before it empties into the inferior vena cava. This venous system ensures efficient return of blood to the heart after filtration in the kidneys.
