EG. water is strongly cohesive, it will form hydrogen bonds. 4 of 17 Adhesion It is the ability of unlike molecules to stick together. EG. water will form intermolecular associations with polar and charged molecules. 5 of 17 Specific Heat Capacity The specific heat capacity of a material is the amount of energy required to raise 1kg of the material by 1°C 6 of 17 Mass Flow Mass flow is the movement of fluids in one direction down a pressure gradient. 7 of 17 Artery Carries oxygenated blood to the rest of the body 8 of 17 Vein Carries deoxygenated blood back to the heart 9 of 17 Capillary Where substances are exchanged between cells and blood. (Metabolic rate) 10 of 17 Cardiac Cycle One complete sequence of filling and pumping blood. 11 of 17 Atrioventricular Valves It is the bicuspid and tricuspid valve. 12 of 17 Systole It is the contraction in the heart. 13 of 17 Dystole It is the relaxation in the heart. 14 of 17 Atrial Systole It is when blood is pumped into the ventricles. 15 of 17 Ventricular systole It is when blood is pumped into the aorta and pulmonary artery 16 of 17 Diastole It is when the atria and ventricles relax and begin to fill with blood. 17 of 17
