Practice Science TEAS Test

Correct Answer: B

Rationale: The correct answer is B: Smooth muscles. Smooth muscles are found in the walls of hollow organs like the stomach, intestines, and blood vessels. They are involuntary muscles responsible for the contraction and relaxation of these organs to facilitate processes like digestion and blood flow. Cardiac muscles (choice A) are found in the heart, skeletal muscles (choice C) are attached to bones for movement, and voluntary muscles (choice D) refer to muscles under conscious control, which can be either skeletal or cardiac but not typically found in the walls of hollow organs.

Correct Answer: D

Rationale: The correct answer is D: Ventral. The frontal cavities are located in the anterior part of the body, which is synonymous with the ventral cavity. The ventral cavity contains multiple smaller cavities, including the thoracic and abdominopelvic cavities. The dorsal cavity is located at the back of the body and does not contain the frontal cavities. Therefore, the correct answer is the ventral cavity as it encompasses all of the frontal cavities within the body.

Correct Answer: C

Rationale: The correct answer is C: Near to the midline of the body. "Medial" refers to being close to the midline of the body or a structure. This term is commonly used in anatomy to describe the position of a body part relative to the midline. Choice A is incorrect as "being face down" is described as prone. Choice B is incorrect as "on the front of the body or limb" is described as anterior. Choice D is incorrect as "above or on top of the lungs" is described as superior. In summary, the term medial specifically refers to proximity to the midline of the body, distinguishing it from the other choices provided.

Correct Answer: A

Rationale: The correct answer is A: Arteries. Arteries carry blood away from the heart because they have thick, muscular walls that can withstand the high pressure of blood being pumped by the heart. Arterioles are smaller branches of arteries, not the main vessels carrying blood away from the heart. Veins carry blood back to the heart, while venules are small vessels that collect blood from capillaries. Thus, the correct choice is arteries as they are specifically designed to carry blood away from the heart with their unique structure and function.

Correct Answer: A

Rationale: The correct answer is A: Abdominal. The peritoneum primarily lines the abdominal cavity, providing a protective and lubricating membrane for the abdominal organs. The peritoneum does not line the dorsal (B), ventral (C), or thoracic (D) cavities. The dorsal cavity is lined by the meninges, the ventral cavity is lined by serous membranes, and the thoracic cavity is lined by the pleura. Therefore, the peritoneum specifically lines the abdominal cavity, making choice A the correct answer.
