How does smoking affect the muscular system?

Answer 1

The main effect of smoking on the muscular system is from what chemicals the blood is carrying, versus carrying oxygen (O2) molecules. If hemoglobin on red blood cells is carrying less O2, then the muscles do not have enough O2 to do the work needed at the cellular level. As a secondary effect, if the person is short of breath from smoking, they are less likely to be active. So muscles become flabby, adding to the amount of work on the muscles and on the body. With less O2, it is harder to exercise and to walk, thus creating a viscous cycle in which muscles don't get worked, the smoking limits respirations, thus getting less O2, and the muscles continue to get flabby.

Answer 2

According to thescooponsmoking.org, the nervous system can be damaged by long-term exposure to nicotine, making a person more susceptible to conditions such as muscular sclerosis. If a person already has a nervous system disorder, smoking can aggravate that disease and possibly make it worse.

nicotine inhalation hardens the nerve walls and disturb the circulation of blood to all parts of body.

Answer 3

Smoking effects the nervous system through it's delivery of nicotine. Nicotine is a central nervous stimulant that increases the release of several neurotransmitters including serotonin, dopamine, and norepinephrine which contribute to it's relaxing and/or stimulating effects. It also effects different chemicals that contribute to focus and memory. The central nervous system raises the blood pressure and heart rate due to the stimulating effects of nicotine.

Answer 4

Surprisingly, in a limited sense, it can -- even though nicotine is a stimulant.

The culprit is carbon monoxide (CO) in the smoke, which combines with the hemoglobin in red blood cells and prevents them from transporting oxygen to the body. Because CO leaves the body very slowly, it is usually present in large quantities in the blood of heavy smokers, who can reduce the ability of their blood to carry oxygen by as much as 50%.

Since the body runs on oxygen and sugar, cutting down the oxygen depresses all bodily functions, causes the heart to beat harder, and reduces the person's overall energy level dramatically.

Answer 5

Tobacco use does long term damage to cardiovascular system and constricts blood flow which will damage brain cells and other body systems.
