Group of answer choices Cellular respiration Ventilation Internal respiration External respiration 2. What is the reason why blood returning to the heart is deoxygenated? Group of answer choices Because the vena cavae soak oxygen out of the blood plasma Because the left and right lungs have used up its oxygen before supplying the blood back to the heart Because the oxygen is placed into hemoglobin and thus taken away from the blood Because the tissues of the body have used up most of the oxygen

4. The number of alveoli continues to increase until about A. 6 years of age B. 8 years of age C. 10 years of age D. 12 years of age
The respiratory system. provides body tissues with oxygen provides body tissues with oxygen and carbon dioxide establishes how many breaths are taken per minute provides the body with carbon dioxide
The inspiratory reserve volume measures the ___________ . amount of air remaining in the lung after a maximal exhalation amount of air that the lung holds amount of air that can be further exhaled after a normal breath amount of air that can be further inhaled after a normal breath
9. Which of the following states that the rate of gas diffusion is inversely proportional to the weight of the gas? A. Graham’s law B. Charles’ law C. Henry’s law D. Gay-Lussac’s law
The respiratory system_______. a. provides body tissues with oxygen b. provides body tissues with oxygen and carbon dioxide c. establishes how many breaths are taken per minute d. provides the body with carbon dioxide
A characteristic of blood circulation through or to the heart is that: a. the superior vena cava conveys blood to the head. b. the inferior vena cava conveys blood to the right atrium. c. the pulmonary arteries convey blood from the lungs to theleft atrium. d. the pulmonary veins convey blood into the left ventricle. e. the aorta branches into two coronary arteries that conveyblood from heart muscle.
Figure 39.13 Which of the following statements is false? In the tissues, PO2 drops as blood passes from the arteries to the veins, while PCO2 increases. Blood travels from the lungs to the heart to body tissues, then back to the heart, then the lungs. Blood travels from the lungs to the heart to body tissues, then back to the lungs, then the heart. PO2 is higher in air than in the lungs.
How would paralysis of the diaphragm alter inspiration? It would prevent contraction of the intercostal muscles It would prevent inhalation because the intrapleural pressure would not change It would decrease the intrapleural pressure and allow more air to enter the lungs It would slow expiration because the lung would not relax.

There is no effect on oxygen concentration in the lungs D. There is a minimal if no effect on oxygen concentration in the lungs
