Question | Answer |
How much of the blood is plasma? | 55% |
How much of the blood is solid elements? | 45% |
Circulatory System Physiology | Transport gases, nutrients, waste, antibodies, hormones & heat, Protection through WBCs & removal of impurities & pathogens, Prevention of hemorrhage through clotting |
Blood | Liquid connective tissue, Viscous, thicker and more adhesive than water, Slightly alkaline, Bright scarlet to dull maroon depending on oxygen content, 100’ F |
Plasma | Straw colored liquid, Transports blood cells |
Fibrogen is for | Blood clotting |
Albumin is for | Blood thickening |
Globulin is for | Protection from infection by being base for antibodies |
Blood is formed in | Red bone marrow of long, flat, irregular bones |
Erythrocytes | RBCs, Transport oxygen, Most numerous |
Hemoglobin | Red pigment, Iron based protein, Combines with oxygen or carbon dioxide for transportation |
Leukocytes | WBCs, Mobile army, Phagocytosis & pinocytosis |
Thrombocytes | Platelets, Repairs by clotting |
Mechanism of Clotting | Vascular spasm, Platelet plug, Coagulation |
What vitamin is necessary for blood clotting? | K |
Blood Types are determined by | Specific antigen (protein) attached to cell |
AB | Universal recipient |
O | Universal donor |
Rh factor | Determines positive or negative blood type |
Heart | Pump |
Pericardium | Double layered sac that protects heart |
Epicardium | Thin outer serous membrane of the heart, Adipose tissue |
Myocardium | Thick middle muscle layer of the heart |
Endocardium | Thin inner lining of the heart |
Atria are located | Top chambers of the heart |
Ventricles | Bottom chambers of the heart |
Right atrium | Receives blood from superior & inferior Vena Cava |
Right ventricle | Blood from right atrium, Out into pulmonary artery |
Left atrium | Oxygen rich blood from pulmonary vein |
Left ventricle | Blood from left atrium out to aorta |
AV (atroventricular valve) | Separate atria and ventricle |
Tricuspid | AV on right |
Bicuspid | Mitral valve on left |
Pulmonary SL | Between right ventricle & pulmonary trunk |
Aortic SL | Between left ventricle & aorta |
Cardiac Cycle is controlled by what part of the brain? | Medulla Oblongata |
Deviation of Heart Rate | Arrythmia |
Slow Heart Rate | Bradycardia, < 50 bpm |
Rapid Heart Rate | Tachycardia, > 100 bpm |
Arteries carry blood | Away from heart |
Smaller blood vessels that carry blood away from the heart | arterioles |
Capillaries | Smallest functional unit, One cell thick, site of gas exchange |
Venules | Smallest vessels that carry blood to the heart |
Veins | Carry blood to the heart |
Lumen | Space in the blood vessel |
Tunica Interna | Inner most layer of blood vessel |
Tunica Medai | Middle layer of blood vessel, smooth muscle & thickest |
Elastic Layer | Layer only found in arteries for expansion |
Tunica Externa | Outer layer of blood vessel |
Vasodilation | Enlargement of lumen diameter |
Vasoconstriction | Shrinking of lumen diameter |
Pulse | Expansion of arteries when the left ventricle contracts |
Stroke Volume | Amount of blood expelled from the left ventricle into the aorta during contraction |
Blood Pressure | Pressure exerted on artery wall when the left ventricle contracts |
Systolic | Top number read during contraction of left ventricle |
Diastolic | Bottom number read when left ventricle is at rest |
Normal Blood Pressure | 120/80 |
High Blood Pressure | 160/95 |
Hyperemia | When blood flow is increased |
Pulmonary Circuit | Deoxygenated blood from R. ventricle to lungs |
Systemic Circuit | Blood leaving L ventricle and going to body |
Hepatic Portal System | Renal circulation, Veinous system that collects blood from digestive organs, Brings blood to liver for digestion & storage |
Coronary | Movement of blood through heart tissues |
