Anastomoses are only found in the heart, and are connections between arteries.

Chronic pericarditis can lead to a buildup of pericardial fluid which results in a life-threatening condition known as cardiac tamponade.

On day 21 following fertilization, the paired endocardial tubes unite to form the primitive heart tube.

The heart is the first organ to function in an embryo, beginning to pump blood on day 22 following fertilization.

The coronary sinus carries oxygenated blood.
