Concept explainers
a.
To determine: The change in
Introduction: Anatomical dead space is the volume of the air in the respiratory system in which no gaseous exchange takes place. It is the air being conducted through the air passage in the respiratory system.
b.
To define: The change in
Introduction: Dead space of the body can change due to different reasons. This change in the anatomical dead space also changes the amount of gases and other parameters of the blood. The maintenance of average anatomical dead space is important to keep the blood parameters within a healthy range.
c.
To define: The change in bicarbonate ion level of Marco’s arterial blood due to the increased anatomic dead space
Introduction: Blood has an optimum physiological ionic concentration. The change of other physiological conditions can change the concentration of different types of ions in the blood. A change in these ionic concentrations is totally dependent on physiological responses of the body towards different stimuli.
d.
To define: The change in the pH level of Marco’s arterial blood due to the increased anatomic dead space.
Introduction: Blood has an optimum pH level for proper functioning. Any deviation in this pH level of the blood can cause different physiological conditions. It may also affect the normal functioning of different biological systems in the body.

- Explain what a partial pressure gradient is and how such gradients figure in gas exchange.arrow_forwardThe average compliance of the lungs and chest wall combined is 0.1 L/cm H2O. 0.2 L/cm H2O 0.3 L/cm H2O 0.4 L/cm H2Oarrow_forwardPeripheral chemoreceptors in the aortic bodies and central chemoreceptors respond to changes in which of the following physiologic parameters? a. H+ alone b. Both H+ and PCO2 c. H+, PCO2, and PO2 d. PO2 alone e. PCO2 alonearrow_forward
- The oxyhemoglobin dissociation (saturation) curve shifts to the right as the blood becomes more acidic. Under these conditions answer the following. At a P O2 = 40 mmHg the percent saturation of hemoglobin __________ and the content of oxygen bound to hemoglobin ____________. A. Decreases; decreases B. Increases; increases C. Increases; decreases D. Decreases; increases E. Does not change; does not changearrow_forward40) At 4:00 am on January 2,2022, emergency services got a call reporting two people in a coma, Emergency workers quickly rushed to the scene and found that 2 people were found comatose in an airtight room with carbon burning. Which of the following statements is correct? A open all doors and windows, and move the patients to a ventilated area as soon as possible B immediately start chest compression in the room C immedately build venous access for fluid resuscitation D immediately give artificial respiration to the patients in the room E immediately put out the charcoal fire in the roomarrow_forwardMAP of the pulmonary system is 21 mmHg, Left Atrial Pressure is 3mmHg, and Flow is 5625ml/min. What is the resistance of the pulmonary circuit? Would this be higher or lower resistance than the systemic circuit? Why do you think so?arrow_forward
- Match the Law/Effect with its definition/description A. Boyle’s Law B. Henry’s Law C. Dalton’s Law D. Haldane Effect E. Bohr Effect 1. The pressure of a gas is inversely proportional to its volume 2. A lower, more acidic pH promotes oxygen dissociation from hemoglobin 3. Hemoglobin saturated with oxygen has a low affinity for carbon dioxide 4. The concentration of a gas in a liquid is directly proportional to the solubility and partial pressure of that gas 5. The total pressure exerted by a mixture of gases is the sum of the partial pressures of the gases in the mixturearrow_forwardIf the partial pressure of O2 in the plasma islow, how will that affect the movement of O2? ● A. O2 will unload from hemoglobin. ● B. O2 will be converted to HbO2. ● C. O2 will load onto hemoglobin. ● D. O2 will stay bound to hemoglobin and only leave if the red blood cell islocated in a capillary.arrow_forwardWhich of the following will cause the largest increase in systemic arterial oxygen saturation in the blood?a. an increase in red cell concentration (hematocrit) of 20%b. breathing 100% O2 in a healthy subject at sea levelc. an increase in arterial PO2 from 40 to 60 mmHgd. hyperventilation in a healthy subject at sea levele. breathing a gas with 5% CO2, 21% O2, and 74% N2 at sea levelarrow_forward
- All of the following are accurate statements about hemoglobin except a. hemoglobin carries oxygen on the Fe ion. b. hemoglobin carries carbon dioxide on the globin. c. hemoglobin carries only a small portion of the total carbon dioxide in the blood (less than 25%). d. hemoglobin releases oxygen at the level of the cell, making hemoglobin more saturated.arrow_forwardVentilation in the capillaries is matched to perfusion. This means that a. blood pressure from capillaries must match the pressure from the arterioles b. gas pressure in the alveolar must match the pressure in the bronchioles c. ventilation is never profuse enough d. ventilation in the alveolar must match the blood flow passing over those alveiolararrow_forwardThe partial pressure of carbon dioxide in the venous blood is O 760 mmHg O 100 mmHg O 0.03 mmHg 46 mmHg O 40 mmHgarrow_forward
