Question 1

Which of the following best describes the relationship between anatomy and physiology?

Accepted Answer

Anatomy studies the structure of body parts, while physiology studies how those parts function. Both are interrelated because form determines function.

Question 2

Which of the following is an example of negative feedback in human physiology?

Accepted Answer

Regulation of blood glucose levels by insulin and glucagon.

Question 3

A patient is unable to sweat and therefore cannot cool down efficiently. Which necessary life function is most directly impaired?

Accepted Answer

Regulation (homeostasis)

Question 4

Which plane divides the body into anterior and posterior sections?

Accepted Answer

Coronal (frontal) plane

Question 5

Which organ system is primarily responsible for filtering blood and removing waste products in the form of urine?

Accepted Answer

Urinary system

Question 6

A patient has a tumor located in the mediastinum. Which of the following organs could be affected?

Accepted Answer

Heart

Question 7

Which of the following best explains why cells are small and numerous rather than large and few in multicellular organisms?

Accepted Answer

Smaller cells have a higher surface area to volume ratio, which facilitates efficient exchange of materials with the environment.

Question 8

Which directional term means 'closer to the point of attachment to the trunk'?

Accepted Answer

Proximal

Question 9

Which imaging technique is most appropriate for visualizing soft tissues such as the brain without exposing the patient to ionizing radiation?

Accepted Answer

Magnetic Resonance Imaging (MRI)

Question 10

Which of the following is NOT a characteristic common to all living things?

Accepted Answer

Photosynthesis

Question 11

A patient is experiencing a rapid drop in blood pressure. Which homeostatic mechanism will most likely be activated to restore normal blood pressure?

Accepted Answer

Negative feedback loop

Question 12

Which of the following best describes the function of serous fluid in body cavities?

Accepted Answer

It acts as a lubricant, reducing friction between moving organs.

Question 13

Which of the following is an example of positive feedback?

Accepted Answer

Amplification of uterine contractions during childbirth

Question 14

Which of the following best describes the chemical level of biological organization?

Accepted Answer

Atoms and molecules that form the building blocks of matter

Question 15

A cross-sectional image of the abdomen is taken. Which anatomical plane was used to obtain this image?

Accepted Answer

Transverse plane

Question 16

Which organ system is responsible for protecting the body from the external environment?

Accepted Answer

Integumentary system

Question 17

Which of the following best explains why homeostasis is important for protein function?

Accepted Answer

Proteins require specific conditions (such as temperature and pH) to maintain their shape and function optimally.

Question 18

Which of the following is the correct order of levels of organization from simplest to most complex?

Accepted Answer

Chemical, cell, tissue, organ, organ system, organism

Question 19

Which directional term would best describe the position of the heart relative to the lungs?

Accepted Answer

Medial

Question 20

Which of the following imaging techniques is most useful for assessing metabolic activity in tissues, such as detecting cancerous tumors?

Accepted Answer

Positron Emission Tomography (PET)
