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 heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
The back surface of the heart lies near the vertebral column, and the front surface known as the sternocostal surface sits behind the sternum and rib cartilages. [7] The upper part of the heart is the attachment point for several large blood vessels—the venae cavae, aorta and pulmonary trunk.
Its largest part is located in the LUQ. ... and may travel from the middle of the stomach to the neck, radiate to the back, or radiate down toward the belly button. ... stones can cause side or ...
From its branches, the upper body, arms, head and neck. As a part of the aorta, the entire body, with exception of the respiratory zone of the lung and the heart. The aortic arch, arch of the aorta, or transverse aortic arch (English: / eɪˈɔːrtɪk / [1][2]) is the part of the aorta between the ascending and descending aorta.
Referred pain, also called reflective pain, [1] is pain perceived at a location other than the site of the painful stimulus.An example is the case of angina pectoris brought on by a myocardial infarction (heart attack), where pain is often felt in the left side of neck, left shoulder, and back rather than in the thorax (chest), the site of the injury.
5031. Anatomical terminology. [edit on Wikidata] In human anatomy, the thoracic duct (also known as the left lymphatic duct, alimentary duct, chyliferous duct, and Van Hoorne's canal) is the larger of the two lymph ducts of the lymphatic system (the other being the right lymphatic duct). [1] The thoracic duct usually begins from the upper ...
The heart works by pumping blood around the body allowing oxygen, nutrients, waste, hormones and white blood cells to be transported. Diagram of the human heart. The heart is composed of two atria and two ventricles. The primary purpose of the atria is to allow uninterrupted venous blood flow to the heart during ventricular systole.
