Circulatory & Blood

Review for Sapulpa Physiology Test

A red protein responsible for transporting oxygen in the blood of vertebrates. Hemoglobin
A red blood cell that (in humans) is typically a biconcave disk without a nucleus Erythrocytes
A colorless cell that circulates in the blood and body fluids and is involved in counteracting foreign substances and disease; a white (blood) cell. Leukocytes
A condition marked by a deficiency of red blood cells or of hemoglobin in the blood, resulting in pallor and weariness Anemia
a bone marrow cell responsible for the production of blood thrombocytes (platelets) Megakaryocytes
Blood Clotting Coagulation
a blood clot formed within a blood vessel and remaining attached to its place of origin Thrombus
A blood clot, air bubble, piece of fatty deposit, or other object that has been carried in the bloodstream to lodge in a vessel. Embolus
A substance on the surface of red Blood cells that elicits an immune response when transfused. Antigen
A blood protein produced in response to and counteracting a specific antigen. Antibodies
A clump of cells (usually erythrocytes) formed as a result of specific chemical interaction between surface antigens and antibodies. Agglutination
A person with this antigen is said to be positive; a person without this antigen is said to be negative. Was first identified in the blood of a rhesus monkey. Rh factor
The rupture or destruction of red blood cells Hemolysis
An escape of blood from a ruptured blood vessel Hemorrhage
A medical condition in which the ability of the blood to clot is severely reduced, causing the sufferer to bleed severely from even a slight injury Hemophilia
An excessive localized enlargement of an artery caused by a weakening of the artery wall Aneurysm
the formation of blood cells in the living body (especially in the bone marrow) Hematopoiesis
The ratio of the volume of red blood cells to the total volume of blood Hematocrit
The phase of the heartbeat when the heart muscle relaxes and allows the chambers to fill with blood Diastole
The phase of the heartbeat when the heart muscle contracts and pumps blood from the chambers into the arteries Systole
The artery carrying blood from the right ventricle of the heart to the lungs for oxygenation Pulmonary artery
A vein carrying oxygenated blood from the lungs to the left atrium of the heart Pulmonary vein
A partition separating two chambers, such as that between the chambers of the heart. Septum
a semi-lunar valve between the left ventricle and the aorta; prevents blood from flowing from the aorta back into the heart Aortic Valve
a semi-lunar valve between the right ventricle and the pulmonary artery; prevents blood from flowing from the artery back into the heart Pulmonary Valve
A blood vessel carrying blood from the right ventricle of the heart to the lungs for oxygenation Pulmonary artery
A blood vessel carrying oxygenated blood from the lungs to the left atrium of the heart Pulmonary vein
smallest blood vessel where oxygen, carbon dioxide, and nutrients can be exchanged between the blood and body tissue. Capillaries
Any part of the circulation system by which blood is conveyed from the heart to all parts of the body Artery
a blood vessel carrying in most cases oxygen-depleted blood toward the heart Veins
The main artery of the body, supplying oxygenated blood to the circulatory system; largest blood vessel in the body Aorta
receives blood from the head and arms and chest and empties into the right atrium of the heart;The main vein leading into the heart. Superior Vena Cava
receives blood from lower limbs and abdominal organs and empties into the posterior part of the right atrium of the heart; formed from the two iliac veins Inferior Vena Cava
the part of the thoracic cavity between the lungs that contains the heart and aorta and esophagus and trachea and thymus Mediastinum
pointed lowest superficial part of the heart Apex of the Heart
the membranous sac enclosing the heart Pericardium
the space between the layers of the pericardium that contains fluid that lubricates the membrane surfaces and allows easy heart movement Pericardial cavity
the innermost of the two layers of the pericardium Epicardium (visceral)
outermost layer of the pericardium Parietal pericardium
The muscular tissue of the heart Myocardium
smooth membrane that lines the inside of the chambers of the heart Endocardium
a clear watery fluid secreted by the cells of a serous membrane Serous Fluid
specialized muscle tissue in the wall of the right atrium of the heart that acts as a pacemaker SA(sinoatrial) node
heart tissue that conducts the impulse from the bundle of his to the myocardium for contraction of the ventricles Purkinje Fibers
the impulse which appears on an EKG which is the result of the atria contracting. P wave
part of an ECG rhythm showing the result of the ventricles contracting QRS wave (complex)
a graphical recording of the cardiac cycle ECG (EKG)
represents the repolarization (or recovery) of the ventricles T wave
An inadequate blood supply to an organ or part of the body Ischemia
rapid contractions of the heart muscle Fibrillation
An abnormally rapid heart rate Tachycardia
abnormally slow heartbeat Bradycardia
a collection of heart muscle cells specialized for electrical conduction that transmits the electrical impulses from the AV node to the point of the apex. The bundle of His AV Bundle
mass of specialized tissue located at the junction between the two upper chambers of the heart (atria) and the lower two chambers (ventricles) AV node
upper chamber of the heart that receives blood from the venae cavae Right Atrium
lower chamber of the heart that receives arterial blood from the left atrium and pumps it into the aorta Left Ventricle
valve with three cusps; situated between the right atrium and the right ventricle Tricuspid valve
mitral valve: valve with two cusps; situated between the left atrium and the left ventricle Bicuspid valve
upper chamber of the heart that receives blood from the pulmonary veins Left Atrium
lower chamber of heart that receives venous blood from the right atrium and pumps it into the pulmonary trunk Right Ventricle
the blood group whose red cells carry the A antigen Type A blood
the blood group whose red cells carry the B antigen Type B blood
the blood group whose red cells carry both the A and B antigens Type AB blood
the blood group whose red cells carry neither the A nor B antigens Type O blood
