TEAS Practice Test Science Questions
Question 1 of 5
Which part of the heart receives oxygenated blood from the lungs?
Correct Answer: A
Rationale: The correct answer is A: Left atrium. The left atrium receives oxygenated blood from the lungs via the pulmonary veins. This oxygenated blood is then pumped into the left ventricle and circulated to the rest of the body. The right atrium receives deoxygenated blood from the body via the vena cava. Choices B, C, and D are incorrect because the right atrium receives deoxygenated blood from the body, the left ventricle pumps oxygenated blood to the body, and the right ventricle pumps deoxygenated blood to the lungs for oxygenation, respectively.
Question 2 of 5
Which of the following is responsible for transporting oxygen in the blood?
Correct Answer: B
Rationale: The correct answer is B: Red blood cells. Red blood cells contain hemoglobin, a protein that binds to oxygen in the lungs and carries it to tissues throughout the body. This process is essential for oxygen transport and delivery to cells for energy production. White blood cells (A), platelets (C), and plasma (D) do not have the specific function of transporting oxygen in the blood. White blood cells are involved in the immune response, platelets help in blood clotting, and plasma is the liquid component of blood that carries nutrients and waste products.
Question 3 of 5
Which of the following lobes of the brain is primarily responsible for vision?
Correct Answer: B
Rationale: The correct answer is B: Occipital lobe. The occipital lobe is primarily responsible for processing visual information. It contains the primary visual cortex which helps in interpreting visual stimuli. The frontal lobe (A) is responsible for executive functions, the parietal lobe (C) for processing sensory information, and the temporal lobe (D) for auditory processing and memory. Therefore, the occipital lobe is the correct choice for vision processing.
Question 4 of 5
What type of joint is found in the shoulder and hip, allowing for a wide range of motion?
Correct Answer: B
Rationale: The correct answer is B: Ball-and-socket joint. This joint allows for a wide range of motion due to its structure where a rounded end of one bone fits into a cup-like socket of another bone. The shoulder and hip joints are prime examples of ball-and-socket joints, enabling movements in multiple directions. A: Hinge joints, like the elbow, allow movement in one plane. C: Pivot joints, like the neck, allow rotational movement. D: Saddle joints, like the thumb, allow for various movements but not the same wide range as ball-and-socket joints.
Question 5 of 5
Which type of joint connects the bones of the skull?
Correct Answer: B
Rationale: The correct answer is B: Fibrous. Fibrous joints connect bones of the skull with fibrous tissue, providing stability and limited movement. Synovial joints (Choice A) have a joint cavity with synovial fluid for movement but aren't found in the skull. Cartilaginous joints (Choice C) connect bones with cartilage and allow slight movement, not commonly found in the skull. Ball-and-socket joints (Choice D) allow the widest range of motion and are not present in the skull. Therefore, the fibrous joint is the most suitable type for connecting the bones of the skull.
