Heart vocab
| Term | Definition |
|---|---|
| Cardiac | Relating to the heart. |
| Arteries | Blood vessels that carry blood away from the heart (usually oxygenated, except pulmonary arteries). |
| Arterioles | Small branches of arteries that regulate blood flow into capillaries. |
| Capillaries | Microscopic vessels where oxygen, nutrients, and waste products are exchanged between blood and tissues. |
| Venules | Small vessels that collect blood from capillaries and carry it to veins. |
| Veins | Blood vessels that carry blood toward the heart (usually deoxygenated, except pulmonary veins). |
| Valves | Flap-like structures that prevent backflow of blood in the heart and veins. |
| Histology | The microscopic study of tissues. |
| Tunica Externa (Adventitia) | The outermost layer of a blood vessel; provides protection and support. |
| Tunica Media | The middle layer of a blood vessel; made mostly of smooth muscle and elastic tissue. |
| Tunica Interna (Intima) | The innermost layer of a blood vessel; smooth lining that contacts blood. |
| Lumen | The inside space of a blood vessel through which blood flows. |
| Pulmonary Circulation | The flow of blood from the heart to the lungs and back to the heart. |
| Systemic Circulation | The flow of blood from the heart to the rest of the body and back. |
| Right Atrium | Upper right chamber; receives deoxygenated blood from the body. |
| Tricuspid Valve | Valve between right atrium and right ventricle; prevents backflow into atrium. |
| Right Ventricle | Lower right chamber; pumps blood to the lungs. |
| Pulmonary Semilunar (Pulmonic) Valve | Valve between right ventricle and pulmonary artery; prevents backflow. |
| Pulmonary Artery | Carries deoxygenated blood from the heart to the lungs. |
| Pulmonary Veins | Carry oxygenated blood from the lungs to the left atrium. |
| Left Atrium | Upper left chamber; receives oxygenated blood from lungs. |
| Bicuspid (Mitral) Valve | Valve between left atrium and left ventricle; prevents backflow. |
| Left Ventricle | Lower left chamber; pumps oxygenated blood to the body. |
| Aortic Semilunar (Aortic) Valve | Valve between left ventricle and aorta; prevents backflow. |
| Aorta | Largest artery in the body; carries oxygenated blood to systemic circulation. |
| Chordae Tendineae | String-like cords that anchor AV valves to papillary muscles. |
| Septum | Muscular wall dividing right and left sides of the heart. |
| Trabeculae Carneae | Irregular muscular ridges inside the ventricles |
| Papillary Muscles | Muscles that tighten chordae tendineae to prevent valve prolapse. |
| Apex | Pointed bottom tip of the heart. |
| Base | Broad upper portion of the heart where major vessels attach. |
| Left Coronary Artery (Left Main) | Main artery supplying the left side of the heart. |
| Left Anterior Descending (LAD) Coronary Artery | Supplies the front of the left ventricle and septum. |
| Circumflex Artery | Supplies the lateral and posterior portions of the left ventricle. |
| Right Coronary Artery (RCA) | Supplies the right atrium, right ventricle, and part of the conduction system. |
| Carotid Artery | Supplies blood to the head and brain. |
| Descending Aorta | Portion of the aorta traveling downward through the thorax and abdomen. |
| Subclavian Artery | Supplies blood to the upper limbs; branches from the aorta (left) or brachiocephalic trunk (right). |
| Brachiocephalic Trunk | First branch of the aortic arch; divides into right subclavian and right common carotid arteries. |
| Axillary Artery | Continuation of subclavian artery in the armpit region. |
| Brachial Artery | Main artery of the upper arm. |
| Radial Artery | Artery on the thumb side of the forearm; commonly used for pulse checks. |
| Ulnar Artery | Artery on the pinky side of the forearm. |
| Iliac Artery | Branches from the abdominal aorta to supply pelvis and legs. |
| Femoral Artery | Major artery of the thigh. |
| Popliteal Artery | Located behind the knee. |
| Dorsalis Pedis (DP) | Artery on the top of the foot. |
| Posterior Tibial (PT) | Artery located behind the medial ankle; pulse site. |
| Jugular Vein | Drains blood from the head and neck. |
| Brachiocephalic Vein | Formed by the union of the jugular and subclavian veins; drains into the superior vena cava. |
| Subclavian Vein | Drains blood from the upper limb. |
| Axillary Vein | Drains the axillary region and upper limb. |
| Greater Cephalic Vein | Superficial vein on the lateral (thumb) side of the arm. |
| Median Cubital Vein | Connects cephalic and basilic veins; common site for venipuncture. |
| Basilic Vein | Superficial vein on the medial (pinky) side of the arm. |
| Iliac Vein | Drains blood from pelvis and lower limbs into the inferior vena cava. |
| Femoral Vein | Major deep vein of the thigh. |
| Popliteal Vein | Located behind the knee. |
| Greater Saphenous Vein | Long superficial vein running along the medial leg and thigh; commonly used for grafts. |
