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.

- WHAT IF? If your doctor gave you a copy of your ECG recording, how could you determine what your heartrate had been during the test?arrow_forwardQ4. THROUGH A PROPER DIAGRAMN, EXPLAIN ANATOMY OF THE HEART BLOOD, NERVE AND VENOUS SUPPLY?arrow_forwardQ4.4. Describe using diagrams as appropriate the cardiac conduction system within the heart. Sketch and outline the major features of an ECG in a healthy individual.arrow_forward
- Keeping the mammalian cardiac cycle balanced is/are: a. an AV node between the right atria atrium and right ventricle, which induces a wave of contraction. b. pacemaker cells, which compose the AV node and signal theSA node. c. an insulating layer that isolates the SA node from the rightatrium. d. ion channels in pacemaker cells, which close to depolarizetheir plasma membranes. e. neurogenic stimuli from the nervous system.arrow_forwardScenario 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.

Present both a drawing of the trace and explain how/why it is different from the normal trace. pressure:arrow_forwardHQ5. 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.arrow_forward
- Q4.3. Under normal physiological conditions, the pressure-volume relationship for the heart is described in Figure 4.3. Explaining your reasoning, approximate the work associated with the left ventricle under these conditions. 150 125 Phase 3 100 - 75 50 - Phase 4 Work Phase 2 25 Phase 1 25 50 75 100 125 150 Left ventricular volume (mL)arrow_forwardWHAT IF? Suppose that after you exercise regularly forseveral months, your resting heart rate decreases, butyour cardiac output at rest is unchanged. Based on theseobservations, what other change in the function of yourheart at rest likely occurred?arrow_forward1 point Which of the following best describes diastole? The atria contract which force the atrioventricular valves to close The ventricles contract forcing blood to leave the heart and the atrioventricular valves close The ventricles relax and re-fill with blood and the atrioventricular valves open Both atria and ventricles contract at the same time and all valves are open What is NOT the function of hemoglobin in red blood cells? O Delivers CO2 from the body cells Binds and delivers 02 to body cells Involved in blood clotting Involved in fighting off bacteria and viruses The system of blood vessels that carry blood between the lungs and the heart is called the: Systemic circuit Circulatory circuit Pulmonary circuit vascular circuit Why does blood turn dark red as it circulates through the body? It starts to clot. It gets old and dirty flowing through the body. The oxygen in the blood is replaced with carbon dioxide. The farther blood is from the heart, the darker red it is.

On the circulatory system, what are the correct statements? PHYSIOLOGY_advanced (OJO) Pacemaker cells of the heart are neurons with a stable resting membrane potential. Pacemaker cells of the sinus node, located at the left atrium, determine the heart beat frequency. Cardiac output is a function of the heart beat frequency and the stroke volume. The Frank-Starling mechanism allows coupling of the venous return with the stroke volume. Within each capillary bed there is a net loss of liquid to the extracellular space; this imbalance depends on the hydrostatic pressure and the colloid osmotic pressure gradients.arrow_forwardTest Your Understanding 13. SCIENCE, TECHNOLOGY, AND SOCIETY Explain the association between atherosclerosis and ischemic heart disease. Imagine that you were the Surgeon General of the United States. What types of programs would you advocate to decrease heart disease? Do you think that as a society we should invest resources into the development of stem cell therapies for more effective treatment of myocardial infarction?arrow_forward
