Question

question 124
the word septum means:
○ fence or partition
○ nose
○ both nostrils
○ airway

question 125
with ___, blood flows backward through an incomplete pulmonic valve from the pulmonary artery to the right ventricle.
○ pulmonic regurgitation
○ mitral regurgitation
○ tricuspid regurgitation
○ aortic regurgitation

question 126
what is an inflammation of the membrane that covers the brain and spinal cord?
○ hypochondriasis
○ encephalocele
○ encephalitis
○ meningitis

Explanation:

• Question 124: The word "septum" refers to a dividing wall or partition. For example, in the heart, there is an inter - atrial septum and an inter - ventricular septum that separate different chambers.
• Question 125: Pulmonic regurgitation occurs when blood flows backward through an incomplete pulmonic valve (from the pulmonary artery to the right ventricle). Mitral regurgitation is related to the mitral valve (between the left atrium and left ventricle), tricuspid regurgitation to the tricuspid valve (between the right atrium and right ventricle), and aortic regurgitation to the aortic valve (from the aorta to the left ventricle).
• Question 126: Meningitis is the inflammation of the meninges (the membranes covering the brain and spinal cord). Hypochondriasis is a mental disorder related to excessive worry about having a serious illness. Encephalocele is a neural tube defect where brain tissue protrudes through a skull defect. Encephalitis is inflammation of the brain itself.

Answer:

• Question 124: fence or partition
• Question 125: pulmonic regurgitation
• Question 126: Meningitis
