Respiration External respiration is: the exchange of oxygen and carbon-dioxide in the lungs The exchange of gases between air in the lungs and the blood is called: external respiration The function of external respiration is: To carry oxygen into the blood and remove carbon dioxide from it Oxygen passes from blood into tissue, and carbon dioxide passes from tissues into the blood by a process known as: Diffusion The approximate percentage of oxygen in the atmosphere is: 21% Which one of following statements is INCORRECT? exhaled air is dryer than atmospheric air Exhaled air contains: more oxygen than carbon dioxide The brain regulates breathing rate DIRECTLY by: the concentration of carbon dioxide in the blood A CORRECT combination of breathing activities is: diaphragm lowered, ribs raised, air taken in During inspiration: the diaphragm moves downwards A disadvantage of breathing through the mouth is that the: inspired air is purified insufficiently A function of the kidneys is: to regulate the water content of the blood Urea is excreted by the: Kidneys Which one of the following substances is NOT NORMALLY present in urine? Glucose Which one of the following statements is CORRECT? A person who drinks a lot of water but does no additional exercise will have: more urine which is more diluted Which of the following is NOT removed via the kidneys in a healthy person?

Loop of Henle Which one of the following substances is NOT a hormone? Pancreatin Which one of the following does NOT act as an exocrine gland? pituitary gland Acromegaly is most likely to occur in: an adult Acromegaly results from an increased function of the: pituitary gland The hormone which acts on cells to increase amino acid uptake and protein synthesis is: luteinising hormone ACTH influences the secretion of: cortisone Anti-diurefic hormone is released by the: posterior lobe of the pituitary gland Vasopressin (ADH) regulates: the amount of urine excreted by the kidneys The hormone which regulates the body's metabolism is: Thyroxine The element required by the thyroid gland for the production of its hormone is: Iodine Hormones that contain IODINE are produced by the: Thyroid Cretinism is caused by a deficiency of the hormone: Thyroxine When the plasma calcium level falls, parathyroid hormone secretion: Increases The hormone secreted by the parathyroid gland regulates the: level of calcium in blood plasma In tetany there is a low blood level of: Calcium The islets of Langerhans are located in the: Pancreas Insulin in the blood controls the concentration of: Glucose A function of insulin is to: promote the uptake of glucose by the cells Glucagon is a hormone produced by: the alpha cells of the pancreas A person with diabetes loses weight and tires easily because: she is unable to metabolize blood sugar A person with diabetes lacks: Insulin A disease caused by a disorder of the pancreas is:
