Question

Докажите что вдыхание окиси углерода вместе с табачным дымом приводит к снижению концентрации кислорода в крови

Answer 1

Окись углерода  (или угарный газ, или СО) попадает в лёгкие вместе с табачным дымом(т.к. происходит реакция горения).

Связь СО с гемоглобином гораздо прочнее,чем с СО2 и О2,поэтому связавшись один раз с СО гемоглобин уже не отпускает молекулу=> такая клетка путешествует свои 120 дней не выполняя свою функцию газообмена => концентрация кислорода в крови снижена из-за того, что многие клетки связаны с молекулой угарного газа. 

Удачи!!!

Answer 2

The Effect of Inhaling Carbon Monoxide and Tobacco Smoke on Blood Oxygen Concentration

Inhaling carbon monoxide (CO) along with tobacco smoke can lead to a decrease in the concentration of oxygen in the blood. This is due to the fact that carbon monoxide has a higher affinity for hemoglobin than oxygen, which reduces the amount of oxygen that can be transported in the blood.

Carbon Monoxide and Hemoglobin Affinity: - When carbon monoxide is inhaled, it binds to hemoglobin in the blood, forming carboxyhemoglobin, which reduces the blood's ability to carry oxygen. - According to the GOLD (Global Initiative for Chronic Obstructive Lung Disease) 2014 report, carbon monoxide can have a significant impact on the blood's oxygen-carrying capacity.

Impact on Oxygen Transport: - The presence of carboxyhemoglobin reduces the amount of hemoglobin available to bind with oxygen, leading to a decrease in the oxygen-carrying capacity of the blood. - This decrease in oxygen-carrying capacity can result in lower oxygen levels in the bloodstream, affecting the overall oxygen concentration in the blood.

Consequences of Reduced Oxygen Concentration: - When the concentration of oxygen in the blood decreases, it can lead to hypoxemia, which is a condition characterized by low oxygen levels in the blood. - Hypoxemia can have detrimental effects on various bodily functions and organs, as oxygen is essential for cellular respiration and energy production.

In conclusion, inhaling carbon monoxide along with tobacco smoke can indeed lead to a reduction in the concentration of oxygen in the blood, primarily due to the formation of carboxyhemoglobin, which diminishes the blood's ability to transport oxygen effectively.
