Accepted Answer

Vertebral cavity; cerebrospinal fluid

Question 3

Which organ system is primarily responsible for regulating body functions through the secretion of hormones?

Accepted Answer

Endocrine system

Question 4

Hemoglobin is essential for oxygen transport in the blood. If each hemoglobin molecule binds one molecule of $$\mathrm{O}_2$$, how many molecules of $$\mathrm{O}_2$$ can 500 hemoglobin molecules carry?

Accepted Answer

$$500$$

Question 5

Which tissue type is characterized by tightly packed sheets of cells with no visible extracellular matrix (ECM), and is found covering and lining all body surfaces?

Accepted Answer

Epithelial tissue

Question 6

A biopsy reveals a tissue with abundant collagen fibers, few cells, and resistance to tension. Which tissue is most likely being observed?

Accepted Answer

Dense connective tissue

Question 7

Which of the following is NOT a function of the urinary system?

Accepted Answer

Delivers oxygen-rich blood to tissues

Question 8

A tissue sample from the trachea shows a single layer of cells with varying heights. Which epithelial type is present?

Accepted Answer

Pseudostratified columnar epithelium

Question 9

Which organ system returns excess tissue fluid to the cardiovascular system and provides immunity?

Accepted Answer

Lymphatic system

Question 10

Which of the following is a core principle in anatomy and physiology that involves the internal balance of the body?

Accepted Answer

Homeostasis

Question 11

A patient is diagnosed with carcinoma after exposure to a certain material. What is the term for substances that cause carcinoma?

Accepted Answer

Carcinogens

Question 12

Which of the following best explains why water is essential for life, according to the study materials?

Accepted Answer

Water has high heat capacity and solubility, allowing it to transfer nutrients and oxygen.

Question 13

Which tissue type is capable of generating, sending, and receiving electrical messages, and contains cells supported by a unique ECM?

Accepted Answer

Nervous tissue

Question 14

If a patient has damage to the spleen, which tissue type is most likely affected, given its role in filtering blood?

Accepted Answer

Reticular connective tissue

Question 15

Which of the following is true about bone tissue compared to cartilage?

Accepted Answer

Bone contains high amounts of calcium and phosphate salts, blood vessels, and can recover from injury.

Question 16

Which of the following is a real-life example of a feedback loop in the human body?

Accepted Answer

Regulation of blood glucose levels by insulin and glucagon

Question 17

Which of the following is NOT a component of the extracellular matrix (ECM)?

Accepted Answer

Mitochondria

Question 18

A tissue sample shows cells that are capable of generating force by contracting, with little ECM between cells. Which tissue type is this?

Accepted Answer

Muscle tissue

Question 19

Which organ system is responsible for delivering oxygen-poor blood to the lungs and oxygen-rich blood to the tissues?

Accepted Answer

Cardiovascular system

Question 20

Which of the following best describes the difference between systematic and regional anatomy?

Accepted Answer

Systematic anatomy examines the body by individual organ systems, while regional anatomy divides the body into regions of study.
