TEAS Test 7 science Questions
Question 1 of 5
Which of the following is NOT a function of the cardiovascular system?
Correct Answer: D
Rationale: The cardiovascular system is responsible for transporting oxygen to cells (A), maintaining blood pressure (B), and carrying waste products to the kidneys for removal (C). Initiating the immune response (D) is not a function of the cardiovascular system. The immune response is primarily carried out by the immune system, which includes organs like the spleen, thymus, and lymph nodes. Therefore, option D is the correct answer as it pertains to a function outside the scope of the cardiovascular system, making it the odd one out among the given choices.
Question 2 of 5
Through which part of the digestive system are nutrients absorbed into the bloodstream?
Correct Answer: C
Rationale: The small intestine is the primary site of nutrient absorption in the digestive system. It is where the majority of digestion and absorption of nutrients such as carbohydrates, proteins, and fats occurs. The inner lining of the small intestine is covered in tiny finger-like projections called villi, which increase the surface area available for absorption. Nutrients are absorbed through the walls of the small intestine and into the bloodstream to be transported to cells throughout the body. The stomach's main role is to break down food through the action of stomach acids and enzymes but does not absorb nutrients. The large intestine primarily absorbs water and electrolytes from the remaining indigestible food matter, and the esophagus is a muscular tube that transports food from the mouth to the stomach, without being involved in nutrient absorption.
Question 3 of 5
What is the name of the master gland that regulates the function of many other endocrine glands?
Correct Answer: B
Rationale: The pituitary gland is commonly referred to as the master gland because it controls the functions of numerous other endocrine glands in the body. It secretes various hormones that are essential for regulating processes like growth, metabolism, reproduction, and stress response. The thyroid gland (Choice A) primarily regulates metabolism and does not oversee other endocrine glands. The hypothalamus (Choice C) plays a role in regulating the pituitary gland but is not the master gland. The adrenal gland (Choice D) produces hormones related to stress response but is not considered the master gland that regulates other endocrine glands.
Question 4 of 5
Urine, the liquid waste product of the body, travels from the kidneys to the bladder through tubes called:
Correct Answer: A
Rationale: The correct answer is 'Ureters.' Ureters are tubes that connect each kidney to the bladder. They transport urine from the kidneys to the bladder for storage before excretion. The urethra, which is not the correct answer, is responsible for carrying urine from the bladder out of the body. Nephrons, another incorrect choice, are microscopic units within the kidneys that filter blood and produce urine. The renal pelvis, also an incorrect choice, is a structure in the kidney where urine collects before moving into the ureters for further passage to the bladder.
Question 5 of 5
What is the purpose of genetic counseling?
Correct Answer: C
Rationale: The purpose of genetic counseling is to provide information and support to individuals and families with genetic risks. Genetic counselors aim to explain the implications of genetic testing, discuss risks and options, and offer emotional and psychological support to help individuals make informed decisions regarding their genetic health. Choice A is incorrect because genetic counseling is not focused on treatment but rather on providing information and support. Choice B is incorrect as genetic counselors do not primarily diagnose genetic diseases in newborns but rather provide guidance and support based on existing diagnoses. Choice D is not the purpose of genetic counseling; genetic counselors do not collect DNA samples for research purposes but instead focus on assisting individuals and families in understanding and managing their genetic risks.
