| Question | Answer |
|---|---|
| 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. |
| Arterial duct | A blood vessel in a fetus that bypasses pulmonary circulation by connecting the pulmonary artery directly to the ascending aorta. |
| Atrioventricular valve | Either of two heart valves through which blood flows from the atria to the ventricles; prevents return of blood to the atrium. |
| Autonomic nervous system | The part of the vertebrate nervous system that regulates involuntary action. |
| Atrioventricular node | A small mass of specialized cardiac muscle fibers, located in the wall of the right atrium of the heart, that receives heartbeat impulses from the sinoatrial node and directs them to the walls of the ventricles. |
| Blood presure | The pressure exerted by the blood against the walls of the blood vessels. |
| Blood velocity | Speed of blood through the vessels. |
| Chordae tendineae | Any of the tendons extending from the papillary muscles to the atrioventricular valves and preventing the valves from moving into the atria during ventricular contraction. |
| Diastolic pressure | the blood pressure after the contraction of the heart while the chambers of the heart refill with blood |
| Fetal cyrculation | The system of blood vessels and structures through which blood moves in a fetus |
| heart beat | A pulsation of the heart, including one complete systole and diastole. |
| hypertension | Abnormally elevated blood pressure |
| hypotension | Abnormally low blood pressure. |
| lymph node | Any of the small bodies located along the lymphatic vessels, particularly at the neck, armpit, and groin, that filter bacteria and foreign particles from lymph fluid. |
| lymphatic system | An extensive network of capillary vessels that transports the interstitial fluid of the body as lymph to the venous blood circulation |
| oval opening | The septum between the right and left atria of the fetal heart. |
| plasma | The pale yellow or gray-yellow, protein-containing fluid portion of the blood in which the blood cells and platelets are normally suspended. |
| platelets | A minute cell occurring in the blood of vertebrates and involved in clotting of the blood. |
| pulmonary circulation | Circulation of blood between the heart and the lungs |
| Purkinje fibres | Allow the heart's conduction system to create synchronized contractions of its ventricles |
| sinoatrial node | Impulse-generating (pacemaker) tissue located in the right atrium of the heart, and thus the generator of normal sinus rhythm. |
| semi-lunar valve | Permit blood to be forced into the arteries, but prevent back flow of blood from the arteries into the ventricles. |
| septum | A wall, dividing the two ventricles of the heart. |
| systemic circulation | The part of the cardiovascular system which carries oxygenated blood away from the heart to the body, and returns deoxygenated blood back to the heart. |
| systolic pressure | The pressure exerted on the walls of the arteries during the contraction phase of the heart. |
| umbilical artery | Supply deoxygenated blood from the fetus to the placenta in the umbilical cord. |
| umbilical vein | Carries oxygenated blood from the placenta to the growing fetus. |
| Venous duct | Connects the umbilical arteries to the liver. |
