Question 3

Which anatomical plane divides the body into anterior and posterior portions?

Accepted Answer

Frontal (coronal) plane

Question 4

During a physical examination, a clinician asks a patient to lie face up. What is the anatomical term for this position?

Accepted Answer

Supine

Question 5

Which of the following is the correct sequence of levels of organization in the human body, from simplest to most complex?

Accepted Answer

Chemical → Cell → Tissue → Organ → Organ system → Organism

Question 6

Which body cavity contains the heart?

A surgeon needs to access the abdominal organs. Which cavity will they enter?

Accepted Answer

Peritoneal cavity

Question 8

Which of the following is an example of a negative feedback mechanism in the human body?

Accepted Answer

Regulation of body temperature

Question 9

In homeostatic regulation, what is the role of the effector?

Accepted Answer

Question 10

Which organ system is primarily responsible for controlling extrinsic regulation in homeostasis?

Accepted Answer

Nervous and endocrine systems

Question 11

A patient is experiencing rapid blood loss from a severe wound. Which type of feedback mechanism is most likely to be activated?

Accepted Answer

Positive feedback to accelerate clotting

Question 12

Which of the following best illustrates the concept of dynamic equilibrium in homeostasis?

Accepted Answer

Question 13

Which anatomical term describes a structure that is closer to the point of attachment to the body than another structure?

Accepted Answer

Proximal

Question 14

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

Accepted Answer

It moistens serous membranes and reduces friction between organs.

Question 17

Which of the following is an example of autoregulation in homeostasis?

Accepted Answer

A blood vessel dilating in response to decreased oxygen levels in its surrounding tissue
