Question
1) Which three of the following statements accurately describe the blood buffering system in humans? The blood buffering system . . .
2) Freediving is an activity in which a person dives, sometimes to great depth, without the use of scuba gear. The diver must hold his or her breath for the duration of the dive. (The record depth, with no equipment such as diving fins, is 101 m; the official record time is over 11 minutes.) Historically, freediving has been used by pearl divers and sponge divers. Some freedivers hyperventilate (breathe rapidly and deeply) before diving. Hyperventilation can change the concentration of CO2 in the blood and may increase the length of time that a person feels like he/she can hold his/her breath.* How does hyperventilation affect blood pH?
Which three of the following statements accurately describe the blood buffering system in humans? The blood buffering system depends on the ionization of H2PO4 regulates the blood pH at 7.4 +l- one pH unit. n is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid (ionizes into bicarbonate and H+) utilizes the H2CO3 HCO3 conjugate acid/base pair. maintains the pH of blood near 7.4 utilizes the acetic acid/acetate conjugate acid/base pair.Explanation / Answer
1]
Blood buffering system of human
2]
How does hyperventilation affect blood Ph?
It decreases CO2 and H+ in the blood increasing pH
Hyperventilation causes loss of carbon dioxide from the body, causing the pH of blood to increase and become more alkaline
