Select the statement that is true about respirationDuring inhalation, ribs move inward and diaphragm is raised In the trachea, exchange of gases take placeHaemoglobin has greater affinity for carbon dioxide than oxygenAlveolus is the functional unit of the lung

Which statements about gas exchange in the human lung are true?When you inhale there is a higher concentration of carbon dioxide in the alveoli than in the bloodOxygen and carbon dioxide diffuse through the walls of the alveoliOxygen diffuses from the blood into the alveoliWhen you inhale there is a higher concentration of oxygen in the alveoli than in the blood

Which of the following statements is FALSE?Question 22Answera.During exhalation, air exits the lungs by moving against it's pressure gradientb.The contraction of the diaphragm and external intercostal muscles is the first step of inhalationc.During forced breathing, both inhalation and exhalation are active processes that make use of muscle contractionsd.During inhalation, air enters the lungs by moving down its pressure gradiente.According to Boyle's law, pressure and volume are inversely related

Which of the following statement(s) is(are) true regarding exhalation? Question 26 options: there is a decrease in both the lung volume and pressure in the lungs there is a increase in the lung volume and diaphragm moves downward there is a decrease in lung volume and the diaphragm moves downward there is a decrease in lung volume and the diaphragm moves upward there is a increase in the lung volume and the diaphragm moves upward

Learning goal 2: Select all of the options that best complete the following sentence. When we exhale:the diaphragm and intercostal muscles relaxthe lungs expandthe pressure in the lungs increases, forcing air outthe air has more carbon dioxide than inhaled air

Gases constantly move in and out of theblood into the lungs. Identify the gasesthat move in and out of the respiratorysystem
