Practice Problems (TEAS ) Questions and Answers| already Pass Which of the following describes the function of the ribosome? a. protein synthesis b. energy production c. cell movement d. storage of molecules a. protein synthesis Because muscle cells require large amounts of energy to function correctly, which organelles would be prevalent in those types of cells? a. ribosomes b. mitochondria c. cytoskeleton d. cell membrane b. mitochondria Which of the following organelles is responsible for storing genetic information? a. nucleus b. ribosomes c. cell membrane d. lysosomes a. nucleus In the human body, which of the following organs is in a superior position to the lungs? a. stomach b. trachea c. spleen d. heart b. trachea Describe the part of the arm that is most distal to the shoulder of the human body. Distal refers to farthest away. The thumb is farthest away from the shoulder of the body. Which of the following structures changes the volume of the lungs? a. alveoli b. heart c. trachea d. diaphragm d. diaphragm Which of the following statement best explains how the structure of alveoli relates to its function? a. alveoli are large to maximize gas exchange b. the walls the alveoli are thin to increase rate of diffusion c. the walls of the alveoli are thick to prevent pressure buildup d. alveoli are small to increase the transportation of cells b. the walls the alveoli are thin to increase rate of diffusion The thin walls decreases the distance between the air and bloodstream, increasing the rate of diffusion. Which of the following statement best describes the primary function of the respiratory system? a. it transports oxygen and carbon dioxide to cells all over the body. b. it involves the inhalation and exhalation of gases into the environment c. it exchanges gases between the blood and the air in an environment .d. it maintains proper blood level pH c. it exchanges gases between the blood and the air in an environment Which of the following conditions causes a narrowing of airways in the respiratory system? a. influenza b. bronchitis c. asthma d. pneumonia c. asthma Describe what will occur in the blood if the tidal volume in the lungs increases. Increasing the tidal volume will increase diffusion of carbon dioxide out of the bloodstream. Oxygen will increase in the bloodstream. Changing the tidal volume will not have a direct effect on heart rate or surfactant. Which of the following lists the primary parts of the heart? a. blood cells b. muscle tissue split into two chambers c. muscle tissue split into four chambers d. four ventricles c. muscle tissue split into four chambers Which of the following blood components is responsible for transporting oxygen? a. red blood cells b. plasma c. dissolved gases d. leukocytes a. red blood cells Red blood cells contains hemoglobin, which transport oxygen. Which of the following chambers pumps blood toward the lungs? a. left ventricle b. right atrium c. left ventricle d. right ventricle d. right ventricle Left atrium: accepts blood from lungs Right atrium: accepts blood from the body Left ventricle: pumps blood to the body Which of the following statements best describes the function of veins? a. veins carry deoxygenated blood b. veins carry oxygenated blood c. veins carry blood back to the heart d. veins carry blood away from the heart c. veins carry blood back to the heart Veins transport blood from the lungs or he body to the heart. Veins can carry oxygenated or deoxygenated blood. Describe two chambers of the heart that have thicker walls. Why would these chambers be thicker? Ventricles use a large amount of pressure to push blood to different parts of the body. This puts quite a bit of force on these chambers. In which of the following organs does digestion begin? a. mouth b. stomach c. small intestine d. pancreas a. mouth In which of the following organs does the breakdown of proteins begin? a. mucus b. stomach c. small intestine d. pancreas b. stomach Which of the following structures absorbs nutrients in the small intestine? a. mucus b. microvilli c. enzymes d. hormones b. microvilli Which of the following statements best describes peristalsis? a. the partly digested food moving from the stomach to the small intestine. b. the mechanical breakdown of food entering the stomach. c. muscle contractions that move food through the digestive tract. d. chemical digestion of food with the help of enzymes. c. muscle contractions that move food through the digestive tract. Describe the mechanical and chemical digestion of a starch or carbohydrate. Starch begins to the breakdown in the mouth. Chewing breaks the molecules into smaller pieces. --Mechanical Amylase also speeds up process of starches breaking down into smaller molecules. Muscle contractions in the stomach breaking down food particles into chyme. Then, in the small intestines, more enzymes released by the pancreas break down the starches into simple sugars.--Chemical Which of the following actions is controlled by voluntary nerve signals? a. walking b. digestion c. heart beating d. breathing a. walking Which of the following best describes the function of a nerve synapse? a. it carries a nerve impulse away from the nerve body. b. it is responsible for involuntary muscle movements. c. it allows for the passing of signals between neurons and muscles. d. it contains a bundle of fibers that transmit electrical impulses. c. it allows for the passing of signals between neurons and muscles. Which of the following types of muscle cell are often voluntary? a. skeletal b. smooth c. cardiac d. nervous a. skeletal Which of the following types of nerves send message to the brain? a. skeletal b. smooth c. sensory d. motor c. sensory A person put their hand on something hot but quickly removes it. Describe the pathway of the signal and response through the neuromuscular system. Sensory nerves send a message to the central nervous system from the hand. Then, motor nerves send a signal to the muscles of the arm to contract. Which of the following organs produce female gametes? a. ovary b. testes c. prostate d. uterus a. ovary Which is the location where fertilization typically takes place? a. vagina b. penis c. vas deferens d. fallopian tubes d. fallopian tubes Which of the following best describes one function of estrogen? a. production of sperm cells b. maturation of eggs c. release of egg d. fertilization b. maturation of eggs Which of the following results from the production of luteinizing hormone (LH) in males? a. bone growth b. facial hair growth c. testosterone production d. sperm production c. testosterone production Describe how the production of male and female gametes differs. Male gametes, or sperm, are produced by the testes, whereas female gametes, or eggs, are produced by the ovaries. Sperm are constantly produced, but eggs are developed and matured cyclically. Eggs are typically released one at a time, but many sperm can be released at once during ejaculation. Which of the following is the layer of skin that forms a protective, waterproof barrier? a. dermis b. sudoriferous c. sebaceous d. epidermis d. epidermis Which of the following best describes the function of melanocytes? a. secretion of substances like minerals and alcohol b. production of melanin c. absorption of vitamin D d. sensing the environment b. production of melanin Which of the following layers of the skin contains hair follicles? a. dermis b. sudorferous c. sebaceous d. epidermis a. dermis Which of the following layers of the skin contains a layer of dead cells? a. dermis b. hypodermis c. sudoriferous d. epidermis d. epidermis Describe how the integumentary system reacts to a rise in body temperature. If the body gets too hot: the integumentary system uses thermoregulation strategies to cool it off. Sweat is produced by the sebaceous glands. As the water in sweat evaporates, the skin is cooled. Blood vessels also dilate and move closer to the skin surface to try and cool off. Which of the following best describes the kind of message sent in the endocrine system? a. electrical signals between axons b. chemical signals that travel through the bloodstream c. physical sensory signals received through the integumentary system d. audiovisual signals processed through the brain b. chemical signals that travel through the bloodstream Which of the following structures secretes releasing hormones? a. hypothalamus b. pituitary c. pancreas d. liver a. hypothalamus Which of the following is a function of the pineal gland? a. releasing growth hormone b. releasing melatonin c. releasing insulin and glucagon d. releasing luteinizing hormone b. releasing melatonin
