Video transcript

Hello everyone here We have a question asking which of the following factors increases hemoglobin oxygen affinity. To increase hemoglobin oxygen infinity? We want to see a left shifted curve so a an increase in temperature that will lower oxygen's affinity. So A is wrong. Be a decrease in ph that is incorrect. That will decrease oxygen's infinity. See a decrease in the partial pressure of CO2. That will increase hemoglobin oxygen affinity. D. An increase in 23 D. P. G. That will decrease oxygen's of hemoglobin oxygen affinity. So our answer here is see a decrease in the partial pressure of carbon dioxide. Thank you for watching. Bye.

Textbook Question

Which of the following statements regarding the insect tracheal system is/are correct? Select True or False for each statement. T/F Tracheae dilate and constrict during flight or other types of movement, functioning as a 'breathing' mechanism. T/F Spiracles open into the body cavity, allowing direct contact between the air and hemolymph. T/F Tracheae carry oxygen to alveoli; here the oxygen diffuses into the hemolymph to be delivered to tissues. T/F Spiracles can close to minimize water loss.

Frog lungs have a smaller surface area for gas exchange than mammalian lungs. How do frogs compensate for this difference? a. Frog tissue absorbs more oxygen from the blood than mammalian tissue does. b. Frogs breathe more quickly than mammals. c. Frogs also obtain oxygen via diffusion across the skin. d. Frog lung tissue has a greater density of capillary beds than mammalian lung tissue.
