1. Which type of blood vessel carries deoxygenated blood back to the heart?

• A. Arteries
• B. Capillaries
• C. Veins
• D. Lymphatic vessels

Correct answer: C

Rationale: Veins are the blood vessels that carry deoxygenated blood from the body's tissues back to the heart. Deoxygenated blood is transported from the body to the heart through veins, while arteries carry oxygenated blood away from the heart. Capillaries facilitate the exchange of nutrients and gases between the blood and tissues. Lymphatic vessels are responsible for returning excess tissue fluid to the bloodstream and do not primarily carry deoxygenated blood.

2. The coronal plane of the body may also be called the ___________ plane.

• A. sagittal
• B. median
• C. frontal
• D. axial

Correct answer: C

Rationale: The correct answer is C: frontal. The coronal plane of the body is also known as the frontal plane. This plane divides the body into front (anterior) and back (posterior) sections. It is perpendicular to the sagittal plane and divides the body into front and back portions. The term 'coronal' is often used in radiology and anatomy to describe this specific anatomical plane. Choices A, B, and D are incorrect because the sagittal plane divides the body into left and right portions, the median plane is another name for the sagittal plane, and the axial plane is a term less commonly used to describe an anatomical plane.

3. Cavitation is a phenomenon observed in fluids when the pressure falls below its:

• A. Boiling point
• B. Density
• C. Freezing point
• D. Vapor pressure

Correct answer: D

Rationale: Cavitation is a phenomenon where vapor bubbles form in a fluid due to pressure dropping below the vapor pressure of the liquid. When this occurs, the bubbles collapse, creating intense shock waves. The pressure falling below the vapor pressure is what triggers cavitation, not the boiling point, density, or freezing point of the fluid. Therefore, the correct answer is 'Vapor pressure,' as it directly relates to the pressure threshold required for cavitation to happen.

4. Choose the meaning of the word 'riddled' in the following sentence: 'The cavity, once opened, proved to be riddled with infection.'

• A. Challenged
• B. Overrun
• C. Separated
• D. Complete

Correct answer: B

Rationale: The word 'riddled' in this context means filled with or affected by (something undesirable) to a great degree, which aligns with the definition of 'overrun.' In this sentence, the cavity is described as being full of infection, indicating that the infection has spread extensively throughout. 'Challenged' (choice A) implies being tested or provoked, which is not the meaning conveyed by 'riddled.' 'Separated' (choice C) means divided or isolated, which does not fit the context of the sentence. 'Complete' (choice D) means finished or whole, which is the opposite of what is described in the sentence where the cavity is full of infection.

5. Another word for UBIQUITOUS is?

• A. Widespread
• B. Last demand
• C. Uncertainty
• D. Finally reckoned

Correct answer: A

Rationale: The word "ubiquitous" means present, appearing, or found everywhere. Another word that closely relates to this meaning is "widespread," which also refers to something that is prevalent or found in many places. The other choices, such as "last demand," "uncertainty," and "finally reckoned," do not accurately represent the synonym for "ubiquitous."
