Which type of tissue is characterized by cells found on the internal surface of the stomach, no extracellular matrix, tall and thin cells, and the absence of blood vessels?
- A. Epithelial
- B. Connective
- C. Muscle
- D. Cartilage
Correct Answer: A
Rationale: The tissue described in the question, where cells are found on the internal surface of the stomach, are tall and thin, lack an extracellular matrix, and do not contain blood vessels, corresponds to epithelial tissue. Epithelial tissue functions to protect, absorb, and secrete, making it well-suited for lining surfaces and forming barriers in the body.

The orthopedic surgeon informs you that you have broken the middle region of the humerus. What is he describing?
- A. Epiphysis
- B. Articular cartilage
- C. Perichondrium
- D. Diaphysis
Correct Answer: D
Rationale: The correct answer is D, Diaphysis. The humerus is a long bone consisting of a shaft known as the diaphysis. The diaphysis is the middle region of a long bone, while the epiphysis refers to the ends of the long bone. Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints, and the perichondrium is the connective tissue covering the cartilage.
What are the two functions of the male and female reproductive organs?
- A. Production of all cells and production of hormones
- B. Production of interstitial cells and production of hormones

- D. Production of gametes and production of interstitial cells
Correct Answer: C
Rationale: The male and female reproductive organs have two primary functions: the production of gametes (sperm in males and eggs in females) and the production of hormones. Gametes are essential for sexual reproduction, while hormones play a crucial role in regulating various physiological processes in the body, such as growth, development, and reproductive functions.

What force primarily drives filtration in the kidneys?
- A. osmosis
- B. smooth muscle contraction
- C. peristalsis
- D. blood pressure
Correct Answer: D
Rationale: Filtration in the kidneys is primarily driven by blood pressure. The glomerulus filters blood under pressure, allowing small molecules and fluids to pass through into the renal tubules while retaining larger molecules like proteins. Osmosis, smooth muscle contraction, and peristalsis do play roles in kidney function, but blood pressure is the main force responsible for the initial filtration process.
