Question
Chapter 35, Problem 2CT
Summary Introduction
To determine:
The reason for the similarities found in oxygen and carbon dioxide content of blood in pulmonary veins and systemic capillaries and along with the same partial pressure between systemic veins and pulmonary arteries.
Introduction:
Veins are the types of blood vessels that carry deoxygenated blood from the living body back to the heart but the pulmonary veins being an exception carry the oxygenated blood from the lungs of the human beings to the heart. The partial pressure of gas oxygen is defined as the measurement of oxygen in arterial blood.

Sketch a picture of the right and left lungs in anterior view, showing all the fissures and lung lobes, as well as the cardiac notch.
Illustrate and trace the flow of blood in a pulmonary circulation. Label your illustration. Represent the flow of blood using colored arrows. Use red ink to represent oxygenated blood and use blue ink for deoxygenated blood. Give a short explanation of your illustration.
a. Why is a minimum flow rate of 5 Lpm recommended for oxygen delivery by mask?
b. Why will an air entrainment mask never deliver 100% oxygen?
c. Briefly explain why the trans-tracheal catheter requires less oxygen flow than the nasal cannula to achieve a given arterial partial pressure of oxygen.
d. Explain the difference between a high-flow and a low-flow oxygen delivery system. Give an example of each.

- If a person has stopped breathing and is receiving pulmonary resuscitation, would it be better to administer pure oxygen or a mixture of oxygen and carbon dioxide? Why?arrow_forwardCardiovascular changes that occur during inspiration include decreased Right ventricular filling Right ventricular output Pressure gradient from extrathoracic veins to the right atrium Systemic blood pressure Left ventricular contractilityarrow_forwardUsing a flow diagram (arrows), describe the pathway of the pulmonary circulation. Indicate the relative amounts of oxygen and carbon dioxide in the vessels involved.arrow_forward
- Ventilation 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_forwardFigure 6 shows the binding of oxygen to myoglobin and haemoglobin (Y-axis: Fraction saturation) when they are exposed to various partial pressures of oxygen (X-axis: pO2). 0.9 0.8 Myoglobin 0.7 0.6 0.5 0.4 Hemoglobin 0.3 0.2 0.1 2 10 12 Po, (kPa) Figure 6 (i) Briefly compare the protein structure of myoglobin to that of haemoglobin.
