How can smoking effect the rate of respiration?

Answer 1

tobacco smoke damages the respiratory system and strains the circulatory system, resulting in such diseases as emphysema, cancer, and chronic bronchitis.

Answer 2

because the chemicals in the cigarette are harmful to your body and they block your arteries in your lungs ,therefore making it difficult to get air in and out which then effects the rate of your respiration as it will become irregular ,slow down ,speed up or make it difficult for you to breathe .

Answer 3

Smokers' Diseases

Chronic bronchitis. Smokers attempt to cough up excess amounts of phlegm. People, who suffer from this, can't breathe properly due to their bronchi being semi-blocked. Emphysema. Decreased surface area for gas exchange, because the alveoli are broken down. Phagocytes reach tar by making a pathway through the walls of the alveoli.

- Lung cancer. The carcinogenic compounds in tar change the DNA in our airways. They grow and divide in. When they accumulate, it is called a tumour, which may end up growing so large that it blocks the airways and blood vessels.

- Heart disease. Coronary heart disease is caused by nicotine, as large amounts of it increase the chances of blood clots. The heart muscle is damaged by the lack of oxygen.

Tar

A black material found in tobacco. It accumulates in the lungs as an effect of smoking, but doesn't enter our bloodstream.

- Tar is composed of more than 4000 chemical compounds, some of which are carcinogenic.

- It causes the lining of the airways to produce extra mucus, due to irritation. The excess mucus will gather together in the airways because the cilia become too damaged to remove the mucus.

- The phrase "smoker's cough" comes from this syndrome, because smokers cough in order to shift the mucus to the back of the throat.

Nicotine

A stimulating drug which, like heroin, interacts with cells of the nerves at junctions between two nerve cells. It is, quickly, absorbed through the alveoli. It goes into the bloodstream. Effects nicotine has one the body, is that it increases the number of times your heart beats per minute, and it increases blood pressure by narrowing the arterioles. Furthermore, the blood platelets become stickier as an effect of nicotine in the bloodstream.

Carbon Monoxide

This is a hazardous gas. Haemoglobin in red blood cells absorbs it, and as the gas permanently joins with the haemoglobin, there is a 10 percent decrease in the volume of oxygen your blood can carry. As an effect of this, there is an increased strain on the heart, which may already by beating faster as a result of nicotine. Your heart needs more oxygen than usual, but it will not get it, because your coronary arteries are pumping more blood to your heart.

Smoke Particles

Little, burnt fragments. These gather together in the lungs, and hence, the body's system of defence is stimulated, in order to remove them.

Answer 4

Oxygen

is the final electron acceptor in the electron carrier system. The moreo2

available the more efficientcellular respiration

.

Without o2 you would have fermentation instead of cellular respiration.

Answer 5

Smoking can decrease lung function and damage the respiratory system, leading to conditions like chronic bronchitis and emphysema. This can decrease the efficiency of oxygen exchange in the lungs, leading to reduced respiratory rate and difficulty breathing.

Answer 6

the "smoke" stays in the lungs and as it builds starts to form a "tar" in the lung which decreases the efficiency of the lungs

Answer 7

the tar in smoking blocks the lungs causing the smoker to die./ sufficate slowly.
