1 Chapter 13 Cardiovascular System The Arterial SystempDay 5
2 Paths of Circulation Pulmonary Circuit Systemic Circuit Carries blood from the heart to the lungs and backSystemic CircuitCarries blood from the heart to all other parts of the body and back
3 Arterial System Aorta Principle Branches of Aorta Largest diameter artery in body (Fig )Principle Branches of AortaAscending AortaTop of aorta that leads to majorbranches of aortaArch of AortaBrachiocephalic ArteryLeads to Right Subclavian andRight Common CarotidLeft Common CarotidLeft Subclavian Artery
4 Arterial System Cont. Descending Aorta Thoracic Aorta Contains the thoracic aorta and abdominal aortaThoracic AortaBronchial ArteryBronchiPericardial ArteryPericardiumEsophageal arteryesophagusMediastinal arteryMediastinumPosterior intercostal arteryThoracic wall
5 Arterial System Cont. Abdominal Aorta Celiac Artery Organs of upper digestive tractGastric Artery-stomachSplenic Artery-spleenHepatic Arteries-liverSuperior and Inferior mesentericarteries-sm. and lg. intestinesSuprarenal Arteries-adrenal glandRenal Arteries-kidneysGonadal arteries-ovary or testesPhrenic Artery-diaphragmLumbar Artery-posterior ab. WallMiddle Sacral Artery-sacrum and coccyxBranches into common iliac arteries
6 Arterial System Cont. Common Iliac Right Common Iliac Left Common IliacSupplies blood to lower regions of ab. Wall, pelvic organs and lower extremities
7 Arterial System Cont. Arteries to Neck, Head, and Brain Branches of subclavian and common carotid arteries supply blood to structures within neck, head, and brain.Vertebral ArteriesBasilar Artery-branches to pons, midbrain, and cerebellumPosterior cerebral arteries-occipital and temporal lobesCircle of WillisConnects vertebral artery to internal carotid artery systems. Also equalizes blood pressure in the brain’s blood supply.
8 Arterial System Cont. Thyrocervical Arteries External Carotid Artery: Branch to thyroid, paraythyroid, larynx, trachea, esophagus, and pharynx as well as muscles in neck, shoulder, and back.External Carotid Artery:Upward side of head, branching into the neck, face, jaw, scalp and base of skullSuperior Thyroid Artery-larynx and thyroid glandLingual Artery-tongue and salivary glandsFacial Artery-Pharynx, palate, chin, lips and noseOccipital Artery-posterior scalp, meninges, neck musclesPosterior Auricular Artery-ear and lateral scalpMaxillary Artery-teeth, jaw, cheek, and eyelidsSuperficial Temporal Artery-gland and surface of the face and scalp
9 Arterial System Cont. Internal Carotid Artery Follows a deep course upward along the pharynx to the base of the skull. Also contains baroreceptors that maintain B.P.Ophthalmic Artery-eye and eye musclesAnterior Choroid Artery-Choroid plexus and brainArteries of shoulder and upper limbSubclavian-branches into armAxillary Artery- supplies branches to structures in axilla and chest wall, become Brachial Artery that follows the humerus to elbow where it branches into Radial and Ulnar ArteriesUlnar-follows ulnar side down armRadial-follows the radial side of arm-used for pulse
10 Arterial System Cont. Arteries of the Thoracic and Ab. Walls Internal Thoracic ArterySupplies intercostal muscles and mammary glandsArteries of the Pelvis and Lower LimbInternal Iliac Artery-pelvic muscles, visceral structures, gluteal muscles, external repro. OrgansExternal Iliac Artery-main supply to lower limbs-becomes femoralFemoral Artery-anterior surface of upper thighPopliteal Artery-braches off femoral artery at knee, leads to anterior and posterior tibia arteriesAnterior Tibial Artery-between tibia and fibulaPosterior Tibial Artery-larger of the two popliteal, supplies calf and lower leg
