Heart murmurs only occur in individuals with incompetent valves or hearts that are otherwise damaged.  True  False

The fibrous skeleton of the heart functions to: O provide an anchor for the heart valves all of these choice are correct maintain the shape of the heart O provide electrical insulation between the atria and ventricles

Explain how the ventricular volume changes during Systole 3 and why (explain the sequence of events in all heart chambers, valves, and pressure changes in the heart chambers/blood vessels during systole 3)

Hemodynamics are the dynamics of blood flow. Can the Bernoulli's equation be used to study hemodynamics in the cardiovascular system? Why or why not? You should discuss all four of the assumptions of Bernoulli's equation when answering this question. Jugular vein (also subclavian vein from arms) Pulmonary artery Superior vena cava Interior vena cava Hepatic vein Liver Hepatic portal vein Renal vein Iliac vein CO₂ CO₂ Head and arms Lungs Heart Kidneys Trunk and legs Carotid artery (also subclavian artery to arms) Pulmonary vein Aorta Hepatic artery Mesenteric arteries Digestive tract Renal artery Iliac artery

( explain well all point of question with step by step answer. )

True or false:  Impulses through the conduction system of the heart follow the ordered path SA node->conduction myofibers->AV bundle->AV node.

As blood flows from the aorta to the arteries, arterioles, and capillaries and through the venous circulation, it encounters various resistances to flow, which results in pressure drops. Using the table, calculate the resistance for an artery and a capillary. (Note: The viscosity of the blood is 3.5 × 10-3 Pa-s.)

Given the role of potassium in myocardial cell action potentials, explain how hyperkalemia can stop the heart. Make sure to explain in terms of ion movements

‘The heart is adapted to ensure that blood flows in a controlled direction’ (as illustrated by the light purple and blue arrows positioned in Figure 2). Discuss this statement taking into account: • the stages of the cardiac cycle, • the electrical conductivity series, • the role of named valves.
