ATI TEAS 7 Science Questions

Question 1 of 5

Which of the following vessels is responsible for pumping oxygenated blood to the body?

Correct Answer: D

Rationale: The correct answer is D: Aorta. The aorta is responsible for pumping oxygenated blood to the body. This happens after the oxygenated blood leaves the left ventricle of the heart through the aortic valve. The aorta is the largest artery in the body and carries blood to all parts of the body, supplying oxygen and nutrients. The other choices are incorrect because: A: Right ventricle pumps deoxygenated blood to the lungs. B: Left ventricle pumps oxygenated blood to the body. C: Pulmonary artery carries deoxygenated blood from the heart to the lungs for oxygenation.

Question 2 of 5

What is the protective fluid that surrounds the brain and spinal cord?

Correct Answer: B

Rationale: The correct answer is B: Cerebrospinal fluid. This is the protective fluid that surrounds the brain and spinal cord. It acts as a cushion, providing mechanical protection, and helps to maintain a stable environment for the central nervous system. Blood (A) does not directly surround the brain and spinal cord. Myelin sheath (C) is a protective covering of nerve fibers, not the fluid surrounding the brain and spinal cord. Insulin (D) is a hormone involved in regulating blood sugar levels and is not the fluid that protects the brain and spinal cord.

Question 3 of 5

What is the name of the condition characterized by swelling caused by a buildup of lymph fluid?

Correct Answer: B

Rationale: The correct answer is B: Edema. Edema is the condition characterized by swelling caused by a buildup of lymph fluid. Lymph fluid can accumulate in tissues due to various reasons such as lymphatic system blockages or underlying medical conditions. Anemia (A) is a condition characterized by a deficiency of red blood cells or hemoglobin. Hypertension (C) is high blood pressure, not related to lymph fluid buildup. Diabetes (D) is a metabolic disorder affecting blood sugar levels, not directly related to lymph fluid accumulation. In this case, edema is the most appropriate choice as it specifically addresses the swelling caused by lymph fluid buildup.

Question 4 of 5

Which hormone is crucial for stimulating sperm production in males?

Correct Answer: C

Rationale: The correct answer is C: Testosterone. Testosterone is crucial for stimulating sperm production in males as it is the primary male sex hormone responsible for regulating the development of male reproductive tissues. It plays a key role in the production of sperm cells in the testes. Estrogen (A) and Progesterone (B) are female sex hormones and do not have a direct role in sperm production. Insulin (D) is a hormone that regulates blood sugar levels and is not involved in the process of sperm production.

Question 5 of 5

Which of the following vessels is responsible for pumping oxygenated blood to the body?

Correct Answer: D

Rationale: The correct answer is D: Aorta. The aorta is responsible for pumping oxygenated blood to the body. This happens after the oxygenated blood leaves the left ventricle of the heart through the aortic valve. The aorta is the largest artery in the body and carries blood to all parts of the body, supplying oxygen and nutrients. The other choices are incorrect because: A: Right ventricle pumps deoxygenated blood to the lungs. B: Left ventricle pumps oxygenated blood to the body. C: Pulmonary artery carries deoxygenated blood from the heart to the lungs for oxygenation.
