SLS Bio12 Circulatio
SLS Bio 12 Circulation JW
| Term | Definition |
|---|---|
| Anterior Vena Cava | The large venous trunk which receives blood from the lower extremities and from the pelvic and abdominal organs. It travels through the abdomen (from the lower extremities) and returns blood to the right atrium of the heart |
| Antibody | Any of the numerous Y-shaped gamma globulin proteins found in the blood or lymph, and produced by B cells as an immune defense against foreign agents |
| Antigen | Any of the various substances that when recognized as non-self by the adaptive immune system triggers an immune response, stimulating the production of an antibody that specifically reacts with it |
| Aorta | The largest artery in the body which has its origin at the heart. It gives off branches to the extremities, neck and major organs for the purpose of supplying oxygenated blood |
| Arterial Duct | A fetal blood vessel that joins the descending aorta and left pulmonary artery |
| Atrioventricular Valve | The cardiac atrioventricular valves; the mitral and tricuspid valves |
| Autonomic Nervous System | The autonomic nervous system regulates key functions including the activity of the cardiac (heart) muscle, smooth muscles (e.g., of the gut), and glands |
| Atrioventricular Node | The location in the hearts conduction system, between the atria and the ventricles, which conducts the normal electrical impulse from the atria to the ventricles |
| Blood | The circulating fluid (plasma) and suspended formed elements, such as red blood cells, white blood cells and platelets in the vascular system of humans and other vertebrates |
| Blood Pressure | The force that the circulating blood exerts on the walls of the arteries |
| Blood Velocity | The time rate of motion, the distance traveled divided by the time required to travel that distance |
| Blood Vessel | All the vessels lined with endothelium through which blood circulates. A vessel in which blood circulates |
| Capillary-Tissue Fluid Excahange | |
| Carotid Artery | An artery that originates on the right from the brachiocephalic artery and on the left from the aortic arch, runs upward into the neck and divides opposite the upper border of the thyroid cartilage |
| Chordae Tendineae | Cord-like tendons that connect the papillary muscles to the underside of the heart valves |
| Coronary Atery | The arteries that supply the heart with oxygenated blood. There are a number of vessels that are important with regard to coronary artery disease |
| Coronary Vein | one of the veins of the heart that drain blood from the capillary beds of the myocardium through the coronary sinus into the right atrium |
| Diastolic Pressure | The intracardiac pressure during or resulting from diastolic relaxation of a cardiac chamber; the lowest arterial blood pressure reached during any given ventricular cycle |
| Fetal Circulation | |
| Heart Rate | The number of heartbeats per unit of time |
| Hepatic Portal Vein | A large vein that carries blood from the stomach and intestines to the liver |
| Hepatic Vein | A large vein that carries blood from the stomach and intestines to the liver |
| Hypertension | Persistently high arterial blood pressure |
| Hypotension | Abnormally low blood pressure, seen in shock but not necessarily indicative of it |
| Iliac Atery | Either of two large arteries originating from the abdominal aorta; they supply blood to the pelvis, abdominal wall and legs |
| Iliac Vein | A vein on either side of the body which is formed by the union of the external and internal iliac veins and passes upward to join with its fellow of the opposite side to form the inferior vena cava |
| Jugular VVein | Veins in the neck that return blood from the head |
| Left Atrium | The thin-walled chamber of the heart which pumps blood into the left ventricle for ejection into the systemic circulation |
| Left Ventricle | The muscular chamber of the heart which accepts blood from the left atrium and ejects it into the aorta to the systemic circulation |
| Lymph Capillaries | one of the minute vessels connecting the arterioles and venules, the walls of which act as a semipermeable membrane for interchange of various substances between the blood and tissue fluid |
| Lymph Node | Small, bean-shaped organs located throughout the lymphatic system |
| Lymphatic System | The tissues and organs (including the bone marrow, spleen, thymus and lymph nodes) that produce and store cells that fight infection and the network of vessels that carry lymph |
| Lymphatic Veins | The vessels that convey the lymph; they anastomose freely with each other |
| Mesenteric Atery | One of two branches of the aorta that pass between the two layers of the mesentery to the intestines |
| Oval Opening | |
| Plasma | Fluid through which cellular components of blood, lymph, or intramuscular fluid are suspended |
| Platelets | A particle found in the bloodstream that binds to fibrinogen at the site of a wound to begin the blood clotting process. Platelets are formed in bone marrow, where they arise from cells called megakaryocytes |
| Posterior Vena Cava | The large venous trunk which receives blood from the lower extremities and from the pelvic and abdominal organs. It travels through the abdomen (from the lower extremities) and returns blood to the right atrium of the heart |
| Pulmonary Arteries | The short wide vessel arising from the conus arteriosus of the right ventricle and conveying unaerated blood to the lungs |
| Pulmonary Circulation | The circulation of blood through the lungs |
| Pulmonary Trunk | Divides into the right pulmonary artery and the left pulmonary artery, which enter the corresponding lungs and branch along with the segmental bronchi |
| Pulmonary Veins | The veins that return the oxygenated blood from the lungs to the left atrium of the heart |
| Purkinje Fibres | A group of specialised cardiac muscle cells that conduct electrical impulses through the heart and are involved in regulating the heart beat |
| Red Blood Cells | Cell specialised for oxygen transport, having a high concentration of haemoglobin in the cytoplasm |
| Renal Artery | Blood vessel that brings blood into the kidney |
| Renal Vein | The short thick veins which return blood from the kidneys to the vena cava |
| Right Atrium | The thin-walled chamber of the heart which pumps blood into the right ventricle for ejection into the pulmonary circulation |
| Right Ventricle | The muscular chamber of the heart which accepts blood from the right atrium and pumps it through the pulmonary artery into the lungs |
| Sinoatrial Node | The impulse generating (pacemaker) tissue located in the right atrium, under the epicardium at the upper end of the sulcus terminalis |
| Semi-Lunar Valve | Semilunar bone, the valves at the beginning of the aorta and of the pulmonary artery which prevent the blood from flowing back into the ventricle |
| Septum | Any structure that serves as a dividing partition or a wall in between, such as between two tissues or between two cavities |
| Subclavien Artery | Arteries are vessels that carry blood away from the heart |
| Subclavien Vein | The continuation of the axillary vein which follows the subclavian artery and then joins the internal jugular vein to form the brachiocephalic vein |
| Systemic Circulation | The general circulation of the blood through the body, as opposed to the circulation of the blood from the heart to the lungs and back to the heart |
| Systolic Pressure | The pressure exerted on the walls of the arteries during the contraction phase of the heart. Considered abnormally elevated if consistently over 150 mmHg. Systolic blood pressure varies with age, sex, size and relative condition |
| Total Cross-Sectional Area | A transverse cut through a structure or tissue. The opposite of a cross-section is a longitudinal section. By analogy, a study may be cross-sectional or longitudinal |
| Umbilical Atery | The flexible structure, giving passage to the umbilical arteries and vein, which connects the embryo or foetus to the placenta |
| Umbilical Vein | The vein that returns the blood from the placenta to the foetus; traversing the umbilical cord, it enters the foetal body at the umbilicus and passes thence into the liver, where it is joined by the portal vein |
| Valve | A device that controls the flow of a fluid through a pipe |
| Veins | Blood vessel that returns blood from the microvasculature to the heart, walls thinner and less elastic than those of artery |
| Venous Duct | |
| Vessel Wall | Water conducting system in the xylem, consisting of a column of cells (vessel elements) whose end walls have been perforated or totally degraded, resulting in an uninterrupted tube. |
| White Blood Cell | Any of the blood cells that lack hemoglobin, colourless and with nucleus. Its primary role involves the body's immune system, protecting the body against invading microorganisms and foreign particles |
