2022年2月24日 · Aortic root: Section that attaches to the heart. This is the widest part of the aorta. Aortic valve: Three flaps of tissue (leaflets) that snap open and shut to release oxygen-rich blood from the heart. Ascending aorta: Upward curve that occurs shortly after the aorta leaves the heart. Aortic arch: Curved segment that gives the aorta its cane ...

2024年1月30日 · The aorta is the main artery that carries blood away from your heart to the rest of your body. When a problem occurs with the aorta, the heart and the entire body’s blood supply can be put at risk. The American Heart Association explains the role of your aorta and when problems with the aorta occur, such as aortic dissection and aortic aneurysm.

2024年11月9日 · The aorta is the largest blood vessel in the body, carrying oxygen-rich blood from the heart to every organ and tissue. It begins at the left ventricle, extends upward through the chest to form an arch, and continues downward, eventually branching into the iliac arteries just above the pelvis. Divided into four sections—the aortic root, ascending aorta, aortic arch, and …

The aorta (/ eɪ ˈ ɔːr t ə / ay-OR-tə; pl.: aortas or aortae) is the main and largest artery in the human body, originating from the left ventricle of the heart, branching upwards immediately after, and extending down to the abdomen, where it splits at the aortic bifurcation into two smaller arteries (the common iliac arteries).The aorta distributes oxygenated blood to all parts of the ...

2023年3月2日 · The aorta is the main artery responsible for transporting oxygenated blood out of the heart and to the rest of the body. It consists of the ascending aorta, the aortic arch, and descending aorta.

2023年7月24日 · The aorta is the largest vessel within the human body. It originates from the left ventricle of the heart anterior to the pulmonary artery before arching posteriorly and descending along the posterior mediastinum. It descends to the level of the L4 vertebral body where it bifurcates into the left and right common iliac arteries. It is the main artery in the body and …

2024年5月17日 · Through the aortic valve, the heart pumps blood from the left ventricle into the aorta. The aortic valve permits a one-way flow of blood by opening and closing its three leaflets with each heartbeat. Anatomy: This medical topic falls under the specialization of heart and vascular care. An aorta is the largest blood vessel in the human body.

2023年10月19日 · The aortic root is the portion of the aorta that is attached to the heart. A major part of the aortic root is the aortic valve, which allows blood to flow from the heart to the rest of the body when it is open and prevents blood from flowing backwards into the heart when it is closed. Like the rest of the body, the heart also needs to get blood.

The aorta runs right down the middle of your body. But it doesn’t take a completely straight path. It starts at the aortic valve, a special flap that connects the heart to the aorta. The aortic valve’s job is to keep blood from flowing backwards after it’s left the heart. From there, the aorta stretches upwards, towards the neck.

2023年7月25日 · The aorta is the first and largest artery in the body. It is responsible for transporting nutrient-rich blood to the systemic circulation following ejection from the left ventricle of the heart. The aorta extends from the aortic valve of the left ventricle to the proximal iliac bifurcation at the L4 vertebral level. The vessel can be divided into various segments …
