what happens when tar meets haemoglibin??

Question

this is a question that came in my exam earlier wana see if its rite

Answer 1

Tar produces chronic irritation of the respiratory system and is a major cause of lung cancer. Smoke particles irritate the lung airways, causing excessive mucus production. They also indirectly destroy the walls of the lungs' alveoli, which coalesce . Both factors reduce lung efficiency, and tar in tobacco smoke has a direct cancer-causing action. Cigarette smoke also contains carbon monoxide (CO), which may contribute to heart disease and also plays a role in the way that smokers process the air they breathe. Oxygen is carried to the various parts of the body by hemoglobin, a protein in red blood cells. As oxygen enters the bloodstream from the lungs, it binds with hemoglobin. When the hemoglobin reaches its destination, the oxygen splits off to be used within cells, and the hemoglobin returns to the lungs to pick up another partner. That partner, however, can just as easily be carbon monoxide as oxygen. Hemoglobin actually binds much more readily with carbon monoxide than with oxygen. The hemoglobin that binds with CO is unavailable to carry oxygen, and there are only so many hemoglobin molecules in the body at any given time, thus CO interferes with oxygenation of the tissues. Therefore, a fair number of hemoglobin molecules can be engaged in carrying poison rather than life-sustaining oxygen, preventing smokers from participating effectively in high-oxygen-requiring activities such as running a marathon. The body tries to respond to this
chronic condition by creating more red blood cells, but the compensation is incomplete.


I think this will answer your question.
Tar doesn't effect hemoglobin but Co2 that is also brought in from smoking enters hemoglobin.

Answer 2

what is the question? Tar? u mean hemoglobin?

Answer 3

it makes tarogloben!!
