I. Through which order o f vessels does blood flow, as it leaves the heart? A) arteries, arterioles, capillaries, venules, veins B) arteries, veins, venules, arterioles, capillaries C) arterioles, arteries, capillaries, venules, veins D) veins, venules, capillaries, arterioles, arteries E) veins, capillaries, venules, arterioles, arteries 2. Which statement best describes parallel now in the circulatory system? A) The organs of the body are arranged in a parallel circuit to allow adequate flow and pressure to all body systems and maintain homeostasis of blood pressure. B) Parallel flow refers to deoxygenated blood only and not to oxygenated blood. C) Parallel flow refers to the flow of blood just to the heart itself, which keeps it oxygenated at all times. D) In the systemic circuit blood flows from one organ directly to the next, hence in parallel. E) Parallel flow refers to the flow of electrical impulses in the heart. 3. Which of the following is the correct conduction pathway through the heart? A) Purkinje fibers, bundle of His, bundle branches, SA node, AV node B) SA node, AV C) AV node, SA node, bundle branches, bundle of His, Purkinje fibers D) Bundle of His, bundle branches, Purkinje fibers, SA node, AV node E) SA node, Purkinje fibers, A V node, bundle of His, bundle branches node, bundle of His, bundle branch Purkinje fibers 4. Which of the following components of an ECG represents ventricular depolarization? A) P wave B) QRS complex C) T wave D) PQ interval E) TQ segment th flloing comnenents of an ECG represents AV nodal delay?Explanation / Answer
Answer:
1:
Arteries, arterioles, capillaries, venules and veins is the order of the vessel the blood flow, as it leaves the heart.
2:
The organ of the body are arranged in the parallel circuit to allow adequate flow and pressure to all body systems and maintain homeostasis of blood pressue is the statement that best describes the parallel flow in the circulatory system.
3.
SA node, AV node, bundle of his, bundle branches, Purkinje fibre is the correct conduction pathway through the heart.
4:
QRS complex component of an ECG represents ventricular depolarization.
