Question
Chapter 42.1, Problem 3CC
Summary Introduction
To explain: Why a surgery is needed for a baby born with an unclosed hole between the right atria and left atria of heart.
Concept introduction:
In normal human heart, the atria are separated by a thin inter-atrium septum. In the fetal heart, the septum has a small pore called foramen ovale. Normally, the foramen ovale closes at birth, when lungs become functional. In some cases, foramen ovale does not close properly, it is called a patent foramen ovale; a birth defect that requires surgery to rectify.

1) What makes the heart sounds?
2) Know the whole cycle/route that the blood takes from the heart through the various vessels and back to the heart?
WHAT 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?
22. All of the followings are correct, except--------------------------------. A. Pulmonary circuit of birds & mammals is maintained at much lower pressures than systemic circulation
B. Bird embryos have mechanism to shunt of blood from one circuit to the other
C. Mammals fetus has the same pressure on both sides of the heart
D. In amphibians, the blood vessels draining the left and right ventricles have an interconnecting aperture
E. In some fish species that have air breathing organ, the gills remain partly functional

- 4.Why does the right ventricle need to pump the blood to the lungs via the left and right pulmonary arteries? Read and analyze the question and choices CAREFULLY; more importantly, ALWAYS CHOOSE the BEST answer. because the blood originating from the right ventricle will be transported immediately back to the heart via the left and right pulmonary veins because the blood emerging from the right ventricle will be used to oxygenate the heart muscle itself because the blood will be renewed into oxygenated blood because the blood arising from the right ventricle needs to be pumped to all parts of the bodyarrow_forwardQ4.
