1) The ovarian cycle consists of three phases: the follicular phase, ovulation, and the luteal phase.<br />2) The urinary system's main functions include filtering waste products from the blood, regulating blood pressure, and maintaining electrolyte balance.<br />3) Bacterial flora in the digestive system aid in digestion, produce certain vitamins, and protect against harmful bacteria.<br />4) The better indicator of effective ventilation is the end-tidal carbon dioxide (ETCO2) level.<br />5) The major functions of the respiratory system include gas exchange (oxygen and carbon dioxide), regulating blood pH, and protecting the body from inhaled pathogens.<br />6) Blood pressure is the force exerted by blood against the walls of the blood vessels, usually measured in millimeters of mercury (mmHg).<br />7) Arteries carry oxygenated blood away from the heart (except for the pulmonary artery) and have thick, elastic walls. Veins carry deoxygenated blood towards the heart (except for the pulmonary vein) and have thinner, less elastic walls.<br />8) The basic functional unit of the urinary system is the nephron.<br />9) The circulatory system consists of the heart, blood vessels, and blood. It is responsible for transporting oxygen, nutrients, and other essential substances throughout the body.<br />10) An enzyme is a protein that acts as a catalyst to speed up a chemical reaction in the body.
