Arterial body ststem - Coggle Diagram
Arterial body ststem
The aorta is the largest artery in the human body, and it originates directly from the left ventricle of the heart. From the aorta, several major arteries branch off and distribute oxygenated blood to various parts of the body. Here's a brief overview of some of the main arterial divisions:
- Brachiocephalic Trunk: This artery is formed by the merging of the right subclavian artery and the right common carotid artery, just after they leave the chest. It then branches into the right common carotid artery and the right subclavian artery.
- Common Carotid Arteries: These arteries originate from the aortic arch and branch off into the right and left carotid arteries. The right common carotid artery merges with the brachiocephalic trunk, while the left common carotid artery continues independently. The carotid arteries travel up the neck and divide into the external carotid artery and the internal carotid artery.
- Subclavian Arteries: These arteries originate from the aortic arch and travel under the clavicle (collarbone) to supply blood to the upper limb. The right subclavian artery merges with the brachiocephalic trunk, while the left subclavian artery continues independently.
- Coronary Arteries: These arteries originate directly from the aorta and supply blood to the heart muscle itself. The right coronary artery typically supplies the right atrium, right ventricle, and the back of the heart, while the left coronary artery typically supplies the left atrium, left ventricle, and the front of the heart.
- Celiac Artery: This artery originates from the abdominal aorta just below the diaphragm and supplies blood to the abdominal organs, including the liver, spleen, pancreas, and intestines.
- Superior Mesenteric Artery: This artery originates from the abdominal aorta just below the celiac artery and supplies blood to the small intestine and other organs in the abdomen.
- Inferior Mesenteric Artery: This artery originates from the abdominal aorta just below the superior mesenteric artery and supplies blood to the large intestine and other organs in the pelvis.
In addition to the arterial divisions I mentioned earlier, here's a brief overview of some of the other major arteries in the human body:
- Renal Arteries: These arteries originate from the abdominal aorta and supply blood to the kidneys.
- Gonadal Arteries: These arteries originate from the abdominal aorta and supply blood to the reproductive organs (ovaries in women and testes in men).
- Iliac Arteries: These arteries originate from the abdominal aorta and supply blood to the pelvis and lower limbs. The right iliac artery typically continues independently, while the left iliac artery merges with the left common iliac artery to form the external iliac artery and the internal iliac artery.
- External Iliac Artery: This artery originates from the common iliac artery and supplies blood to the thigh and hip.
- Internal Iliac Artery: This artery originates from the common iliac artery and supplies blood to the pelvis and lower abdomen.
- Femoral Artery: This artery originates from the external iliac artery and travels down the thigh. It eventually branches into the popliteal artery (also known as the knee artery) and the profunda femoris artery.
- Popliteal Artery: This artery originates from the femoral artery and travels behind the knee joint. It eventually branches into the anterior tibial artery, the posterior tibial artery, and the peroneal artery.
- Anterior Tibial Artery: This artery originates from the popliteal artery and travels down the front of the leg. It eventually branches into the dorsal pedis artery and the medial malleolar artery.
- Posterior Tibial Artery: This artery originates from the popliteal artery and travels down the back of the leg. It eventually branches into the lateral plantar artery and the medial plantar artery.
- Radial Artery: This artery originates from the brachial artery and travels down the forearm. It eventually branches into the palmar carpal artery and the superficial palmar arch.
- Ulnar Artery: This artery originates from the brachial artery and travels down the inside of the forearm. It eventually branches into the palmar carpal artery and the superficial palmar arch.
In addition to the arterial divisions I mentioned earlier, here's a brief overview of some of the major arteries in the chest, head, and neck:
- Thoracic Aorta: This portion of the aorta originates from the aortic valve and travels through the chest, supplying blood to the chest, back, and upper abdomen.
- Bronchial Arteries: These arteries originate from the thoracic aorta and supply blood to the bronchi and lungs.
- Intercostal Arteries: These arteries originate from the thoracic aorta and supply blood to the intercostal muscles and the skin of the chest.
- Coronary Arteries: These arteries originate directly from the thoracic aorta and supply blood to the heart muscle itself.
- Carotid Arteries: These arteries originate from the common carotid artery and travel up the neck, supplying blood to the head and neck. The right carotid artery typically continues independently, while the left carotid artery merges with the left subclavian artery to form the brachiocephalic trunk.
- Vertebral Arteries: These arteries originate from the subclavian arteries and travel up the neck, supplying blood to the back of the head and neck.
- Internal Carotid Arteries: These arteries originate from the common carotid arteries and travel up the neck, supplying blood to the brain.
- External Carotid Arteries: These arteries originate from the common carotid arteries and travel down the neck, supplying blood to the face, scalp, and neck.
- Superficial Temporal Artery: This artery originates from the external carotid artery and travels across the temple, supplying blood to the scalp and face.
- Maxillary Artery: This artery originates from the external carotid artery and travels through the cheek, supplying blood to the face, scalp, and neck.
- Occipital Artery: This artery originates from the external carotid artery and travels down the back of the head, supplying blood to the scalp and neck.
These arterial divisions are just a few examples of the many ways that the aorta and its branches distribute oxygenated blood throughout the body. Each artery has a specific role in supplying blood to the organs and tissues it serves, and any disruption to these arteries can have serious consequences for overall health and well-being.
