Integumentary system; protection from environmental hazards

Question 3

Which of the following is an example of negative feedback in homeostasis?

Accepted Answer

Release of insulin to decrease high blood glucose levels

Question 4

A person is exposed to cold temperatures and begins to shiver. Which homeostatic control mechanism is primarily responsible for this response?

Accepted Answer

Effector

Question 5

Which anatomical term describes a structure that is farther from the point of attachment to the body trunk?

Accepted Answer

Distal

Question 6

A patient has a blood pH of 7.55. Which survival need is most directly affected, and what is the likely consequence?

Accepted Answer

Nutrients; disruption of chemical reactions

Question 7

Which organ system is responsible for transporting oxygen, nutrients, and wastes throughout the body?

Accepted Answer

Cardiovascular system

Question 8

Which of the following best illustrates a positive feedback mechanism?

Accepted Answer

Enhancement of labor contractions by oxytocin during childbirth

Question 9

If a person’s body temperature rises above 37°C, which process is most likely to be affected first?

Accepted Answer

Rate of chemical reactions

Question 10

Which of the following equations best represents the process of cellular respiration?

$$\mathrm{C_6H_{12}O_6$} + 6\mathrm{O_2$} ightarrow 6\mathrm{CO_2$} + 6\mathrm{H_2O} + 	ext{energy}$$

Question 11

Which anatomical direction term means 'toward the midline of the body'?

Accepted Answer

Medial

Question 12

A patient is unable to regulate blood glucose levels due to insufficient insulin production. Which organ system is most directly involved?

Accepted Answer

Endocrine system

Question 13

Which of the following is NOT a necessary life function?

Accepted Answer

Photosynthesis

Question 14

Which level of structural organization is defined as a group of similar cells performing a common function?

Accepted Answer

Tissue level

Question 15

A person suffers a heart attack due to failure of homeostatic mechanisms. Which of the following best describes this situation?

Accepted Answer

Disturbance of homeostasis leading to increased risk of disease

Question 16

Which of the following is the correct sequence for homeostatic control mechanisms?

Accepted Answer

Receptor → Control center → Effector

Question 17

Which anatomical plane divides the body into right and left parts?

Accepted Answer

Sagittal plane

Question 18

Which organ system is primarily responsible for removing nitrogenous wastes from the blood and regulating water, electrolyte, and acid-base balance?

Accepted Answer

Urinary system

Question 19

A person is unable to maintain a relatively stable internal environment despite changes in the external environment. Which process is failing?

Accepted Answer

Homeostasis

Question 20

Which of the following best describes the function of the lymphatic system?
