True or false: Blood in the pulmonary capillaries has a higher partial pressure of carbon dioxide than atmospheric air does. Therefore, carbon dioxide diffuses out of the plasma into the lungs.True false question.TrueFalse

Assertion : Both oxygen and carbon dioxide have to be transported by the blood.Reason : The heart pumps blood to the lungs for oxygenation and to the rest of the body to deliver oxygen.Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.Assertion is true, but Reason is false.Assertion is false, but Reason is true.       What happens to carbon dioxide in the lungs?It is absorbed into the bloodstreamIt is exchanged for oxygen in the alveoliIt is converted into bicarbonate ionsIt is stored in the lung tissue

Where does most of the carbon dioxide travel in the blood vessels?plasmared blood cellswhite blood cells

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

What percentage of blood is composed of plasma?45%55%65%75%       Assertion: Plasma transports carbon dioxide dissolved in blood.Reason: Carbon dioxide is a waste product transported from tissues to the lungs for exhalation.Options:Both assertion and reason are correct, and the reason correctly explains the assertion.Both assertion and reason are correct, but the reason does not correctly explain the assertion.Assertion is correct, but the reason is incorrect.Assertion is incorrect.       Why does the heart have different chambers?To regulate blood pressureTo prevent oxygen-rich blood from mixing with carbon dioxide-rich bloodTo filter waste products from the bloodTo produce red blood cells       Label the parts numbered 1 and 2 in the diagram,1) Aorta 2) Vena Cava1) Vena Cava 2) Pulmonary Veins1) Pulmonary arteries, 2) Pulmonary veins1) Aorta, 2) Lung capillaries       When the muscular left ventricle contracts, what happens to the blood?It is pumped out to the bodyIt is transferred to the right atriumIt is collected in the left atriumIt is oxygenated in the lungs       One-cell thick walled, smallest blood vessels are called?ArteriesVeinsCapillariesVenules       Where does the breakdown of glucose into pyruvate take place?MitochondriaNucleusCytoplasmEndoplasmic reticulum       What type of reactions in the cell are driven by the energy released from ATP breakdown?Exothermic reactionsEndothermic reactionsSpontaneous reactionsNeutral reactions       What is the primary molecule synthesized using the energy released during cellular respiration?GlucoseOxygenATPBoth A and C       How do plants primarily exchange gases with their environment?Through their rootsThrough their flowersThrough stomataThrough their seeds

Compared with blood in the pulmonary veins, blood in the pulmonary arteries has higher concentrations of:O2H+CO2A.I and II onlyB.I and III onlyC.II and III onlyD.I, II, and IIISubmit
