NOTE: - atomic #= 35 - atomic mass= 79.9 a) 35 b) 44.90 c) 45 d) 79.90 (Test 1) - CORRECT ANSWER IS b) 44.90 to determine the number of neutrons (n), subtract the atomic number (35) from the atomic mass (79.9) 79.9 - 35 = 44.90 On average, how many protons does one atom of zinc (Zn) have? NOTE: - atomic # = 30 - atomic mass = 65.39 a) 30 b) 35 c) 35.39 d) 65.39 (Test 1) - CORRECT ANSWER IS a) 30 - The number of protons is the atomic number - The number of protons is the same for every atom of a given element  What is the name of the structure that prevents food from entering the airway? a) trachea b) esophagus c) diagram d) epiglottis (Test 1) - CORRECT ANSWER IS d) epiglottis "the epiglottis covers the trachea during swallowing, thus preventing food from entering the airway" ?= aka the windpipe - is a cylindrical portion of the respiratory tract that joins the larynx with the lungs (Test 1) - CORRECT ANSWER IS Trachea ?= connects the throat to the stomach - when someone swallows, this contracts to force the food down into the stomach - like other structures in the respiratory system, this structure secretes mucus for lubrication (Test 1) - CORRECT ANSWER IS Esophagus  What is the name of the process in the lungs by which oxygen is transported from the air to the blood? a) osmosis b) diffusion c) dissipation d) reverse osmosis (Test 1) - CORRECT ANSWER IS b) diffusion cannot be osmosis- osmosis is the movement of a solution from an area of low conc to an area of higher conc through a permeable membrane cannot be dissipation- dissipation is any wasteful consumption or use cannot be reverse osmosis- a process for purifying a solution by forcing it through a membrane that blocks only certain pollutants  Which gland is responsible for the regulation of calcium levels? a) parathyroid glands b) thyroid glands c) adrenal glands d) pancreas (Test 1) - CORRECT ANSWER IS a) parathyroid glands "The parathyroid glands are 4 small glands that sit on top of the thyroid gland and regulate calcium levels by secreting parathyroid hormone. The hormone regulates the amount of CALCIUM & MAGNESIUM that is excreted by the KIDNEYS into the URINE" Which secretion of the digestive system is responsible for water reabsorption? a) large intestine b) duodenum c) small intestine d) gallbladder (Test 1) - CORRECT ANSWER IS a) large intestine LI main functions: - reabsorption of water into body to form solid waste** - allows for absorption of vit K  Which of the following describes one responsibility of the integumentary system? a) distributing vital substances (such as nutrients) throughout the body b) blocking pathogens that cause diseases c) sending leaked fluids from the cardiovascular system back to the blood vessels d) storing bodily hormones that influence gender traits (Test 1) - CORRECT ANSWER IS b) blocking pathogens that cause diseases "The integumetnary system includes skin, hair, & mucous membranes, all of which are responsible (in part) for blocking disease-causing pathogens from entering the blood stream" IT CANNOT be A b/c the circulatory system distributes vital substances through the body IT CANNOT be C b/c the lymphatic system sends leaked fluids from the cardiovascular system back to the blood vessels IT CANNOT be D b/c the reproductive system stores bodily hormones that influence gender traits  When are the parasympathetic nerves active w/in the nervous system? When an individual.... a) experiences a strong emotion, such as fear or excitement b) feels pain or heat c) is either talking or walking d) is either resting or eating (Test 1) - CORRECT ANSWER IS d) when an individual is either resting or eating  When are the sympathetic nerves active w/in the nervous system? When an individual.... a) experiences a strong emotion, such as fear or excitement b) feels pain or heat c) is either talking or walking d) is either resting or eating (Test 1) - CORRECT ANSWER IS a) when an individual experiences a strong emotion, such as fear or excitement  When are the sensory neurons active w/in the nervous system? When an individual.... a) experiences a strong emotion, such as fear or excitement b) feels pain or heat c) is either talking or walking d) is either resting or eating (Test 1) - CORRECT ANSWER IS b) when an individual feels pain or heat  When are the sensory-somatic ns active w/in the nervous system? When an individual.... a) experiences a strong emotion, such as fear or excitement b) feels pain or heat c) is either talking or walking d) is either resting or eating (Test 1) - CORRECT ANSWER IS c) when an individual is either talking or walking  Which of the following best describes the relationship b/w the circulation system & the integumentary system a) removal of excess heat from body b) hormonal influence on bp c) regulation of blood's pressure and volume d) development of blood cells w/in marrow (Test 1) - CORRECT ANSWER IS a) removal of excess heat from body "the integumentary system (ie: skin, hair, etc) coordinates with the circulatory system to remove excess heat from the body. The superficial blood vessels (nearest the skin surface) dilate to allow the heat to exit the body" NOT B b/c the hormonal influence on bp is the result of the relationship b/w the circulatory system and the endocrine system NOT C b/c the urinary system is responsible for assisting in the regulation of blood's pressure and volume NOT D b/c the skeletal system is responsible for assisting in the development of blood vessels w/in the marrow The hormonal influence on bp is the result of the relationship between the circulatory system & the ? system (Test 1) - CORRECT ANSWER IS Endocrine System The ? system is responsible for assisting in the regulation of blood's pressure and volume (Test 1) - CORRECT ANSWER IS Urinary System The ? system is responsible for assisting in the development of blood vessels w/in the marrow - CORRECT ANSWER IS Skeletal System  Once blood has been oxygenated, it travels through the pulmonary veins, through the left atrium, and then through the ? before entering the left ventricle a) tricuspid valve b) mitral valve c) pulmonary arteries d) aorta (Test 1) - CORRECT ANSWER IS b) mitral valve
