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.

Q4. THROUGH A PROPER DIAGRAMN, EXPLAIN ANATOMY OF THE HEART BLOOD, NERVE AND VENOUS SUPPLY?
19. 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

Oxygen-rich blood
Carbon dioxide-rich blood

3. Compare and contrast (in other words, describe similarities and differences of) the circulatory systems of
the perch and the frog, with reference to how each system supports the lifestyle (including activity level)
of each animal:

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_forwardHQ5.
