Homework Answers
Option A is correct
oxygen concentration is higher in the lungs than in the blood returning from the body, A normal oxygen level for healthy lungs falls between 80 and 100 millimeters of mercury (mm Hg). while the blood returning from tissue having oxygen concentration is about 40mmHg.

During respiratory exchange, carbon dioxide moves from the blood into the alveoli due to: the presence of a permease , which removes carbon dioxide from the capillaries. the contraction of the diaphragm, which creates a vacuum that pulls it out. diffusion down a concentration gradient. the air pressure of dissolved oxygen, which forces it out. two of the choices are correct

Name 13. During gas exchange in the lungs, several factors affect the rate of gas diffusion across alveolar (the alveoli are tiny air sacs in the lungs) and tissue membranes. One of the factors is the difference in partial pressures of the gases across the membranes. The gases will diffuse from an area of high partial pressure to an area of low partial pressure, Look at the illustration below and note which blood vessels carry blood away from the lungs...
Which blood vessel contains blood that has high oxygen concentration, low carbon dioxide concentration, and high pressure
Which blood vessel contains blood that has high oxygen concentration, low carbon dioxide concentration, and high pressure? 1. aorta 2. pulmonary artery 3. pulmonary vein 4. vena cava I wrote the answer as 3, but is wrong. Which one is the correct answer?

Respiration must deliver oxygen to our cells and take carbon dioxide, the waste product, to the lungs to be exhaled. Dalton's law of partial pressures helps to explain the way in which this process occurs. Why is a low concentration of CO 2 in our blood good while a high concentration is bad
