Chapter 34.1, Problem 3CC
Summary Introduction
To determine:
The effect of hole in heart as if the heart of a normally developed human fetus has a hole between left and right atria and in some cases the whole does not completely before birth. If it is not surgically corrected, how would it affect the O2 content of the blood entering into the systemic circuit.
Introduction:
Heart is a muscular organ present in the left side of the breastbone. It pumps blood through the network of arteries and veins know as cardiovascular system. Human has four chambered heart in which two atria and two ventricles are present and are separated by a valve. Blood flow in human body is facilitated by double circulation.

HQ5. Correctly sequence the pathway of blood flow through the heart, beginning with the venae cavae, by placing the numbers on the appropriate structures of the heart.
Scenario 2-One very unhealthy-looking human goes into atrial fibrillation while working out in
the Vegan gym. This is when the SA node is not generating coordinated electrical impulses. Instead,
impulses are flowing randomly over the atrial walls eventually making their way to the AV node. The
AV node then generates normal electrical impulses. The result of this appears to be normal ventricular
contraction, but the atria just wiggle around, and atrial contraction is not well coordinated.
Predicted effect on systolic and dastolic blood
Predicted effect on the EKG trace. Present both
a drawing of the trace and explain how/why it is
different from the normal trace.

- 5.According to Steven et al., (2006), hypoplastic left heart syndrome is a medical terminology used to describe a spectrum of congenital heart malfomation exhbiting an array of underdeveloped structures in the left side of the heart. How does this affect the anatomical and physiological function of the left side of the heart? Read and analyze the question and choices CAREFULLY; more importantly, ALWAYS CHOOSE the BEST answer. The heart will have a difficulty in pumping oxygenated blood to all parts of the body The heart is bound to enlarge by loosening its myocardium after a few years. The heart will not be able to absorb oxygen from the lungs. The heart will exert too much pressure to deliver oxygen-poor blood to the lungs.arrow_forward19. The diagram below is a schematic representation of the circulatory system. In other words, it is not meant to be a realistic drawing of body parts, but only to show the basic scheme of the system – the relationships among its parts and the sequence of events that occur in the system. The circulation of blood is vital to the process of respiration, since the blood carries fresh oxygen to the cells of the body and returns carbon dioxide to the lungs to be expelled. As you have learned, arteries are the blood vessels that carry blood away from the heart. Which blood vessels in the diagram are arteries? The arrows indicate the blood vessels 2 and 3 carry blood away from the heart, so they are arteries. Blood vessels 1 and 4, which return blood to the heart, are veins. Study the diagram below and then answer the questions that follow. Heart Body cells Lungs Key: Oxygen-rich blood Carbon dioxide-rich blood A. Refer to the diagram.
