small cardiac vein
great cardiac vein
Middle cardiac (and posterior vein of left ventricle) *both drain in coronary sinus*
The azygos vein forms near the diaphragm; runs anterior and to the right of the vertebral column and ends in the superior vena cava. These veins drain most thoracic structures and the abdominal wall.
The answer is the hepatic portal vein,Unlike most veins, the hepatic portal vein does not drain into the heart. Rather, it is part of a portal venous system that delivers venous blood into another capillary system, namely the hepatic sinusoids of the liver. The hepatic portal vein (often simply portal vein) is a vein in the abdominal cavity that drains blood from the gastrointestinal tract
The Eustachian tube is the most anterior.
The pulmonary vein is the most important vein found in the heart because it brings oxygenated blood from the lungs into the left atrium.
The Pubis is the most anterior part of the hip bone, or the pubic bone as it should be called
The Pubis is the most anterior part of the hip bone, or the pubic bone as it should be called
metacarpal or median cubital vein or forearm
Unoxygenated blood would be found in a vein.
Most have one that is partially divided into two sub-chambers. This division can also be considered to be two ventricles. Crocodiles have a two ventricles that are completely divided from each other.
The heart pumps oxygenated blood only, all deoxygenated blood goes through veins so i think you are thinking about the aorta, which is the most important artery. And the myocardium is just the second layer of the heart, it isn't a part per se.
What animals? As anterior means front and posterior means back, then most-if not all animals have a front and back, or an anterior and posterior. They are usually characterized by a mouth(anterior) or rectum/anus (posterior).
