Let me think... Arteries!!!!The main artery that begins with 'a' is the aorta. It is the artery that comes out of the right ventricle and provides the whole body with oxygenated blood.
Intercostal Arteries
''Distal right coronary artery continuation segment (R PAV): The terminal portion of the right coronary artery in a right dominant circulation. This segment lies in or near the atrioventricular (AV) groove and gives rise to a variable number of right posterolateral segments. This segment is the terminal portion of the right coronary artery and begins at the bifurcation of the distal RCA and PDA and gives rise to the AV nodal artery as well.
Blood returning from its cycle through the body is not oxygenated. Once the blood reaches the heart it is then sent to the lungs, where it is oxygenated, then returns to the heart to be sent through the body.
In the human heart, the pulmonary trunk (pulmonary artery or main pulmonary artery) begins at the base of the right ventricle. It is short and wide - approximately 5 cm (2 inches) in length and 3 cm (1.2 inches) in diameter. It then branches into two pulmonary arteries (left and right), which deliver deoxygenated blood to the corresponding lung.

Aorta Artery
Intercostal Arteries
Blood flow in the leg begins at the femoral artery. From there, it runs to the popliteal artery, anterior tibial artery, dorsalis pedis artery, and finally, the dorsal metatarsal arteries.
The aorta is the main artery leaving the heart. It begins at the top of the left ventricle and travels upwards before splitting into smaller arteries.
just follow this sequence: inferior/superior vena cava (DEOXYGENATED BLOOD) --> right atrium--> passes through tricuspid valve--> right ventricle--> pulmonary artery--> lungs (OXYGENATED BLOOD)--> pulmonary veins--> left atrium--> passes through bicuspid valve--> left ventricle--> aorta--> different parts of the body. it would be much easier if you have a picture of the heart with you. then just go with the flow. you can actually begin anywhere because it's just a cycle but most books would normally start with the one I've given above.
I believe the word you want is aneurism. That is why you could not find it in a dictionary. It begins as a ballooning in an artery. If it is in your brain, it is called a stroke. If it is in your aorta it is frequently called death.

Your major body systems stop functioning and your body begins to decompose.
The main trunk of the arterial system that begins from the left ventricle of the heart is the aorta. The aorta is the largest and primary artery in the body, responsible for carrying oxygen-rich blood to all parts of the body.
Pulmonary circulation begins in the right ventricle of the heart, where blood is pumped to the lungs to pick up oxygen. It ends in the left atrium, where oxygenated blood returns from the lungs to be pumped out to the rest of the body.
