The effects of cigarette smoking on the human body are serious and in many cases, deadly. There is said to be approximately four thousand chemicals in cigarettes and of this four thousand, hundreds of them are said to be toxic. The chemicals in cigarettes affect the human body immensely from the internal functions of organs to the productivity of the body's immune system. Three common effects of cigarette smoking on the human body are heart attacks, cancer, and infertility.
Firstly, the mixture of nicotine and carbon monoxide in each cigarette momentarily increases the smoker’s heart rate and blood pressure. This increases in heart rate and blood pressure damages their heart and blood vessels which cuts off oxygen to their feet and hands. This is one of the main ways in which cigarette smoking can cause heart attacks and stroke.
Another example of how cigarette smoking affects the human body is Emphysema. Emphysema is an illness that slowly deteriorates and causes severe damage to lungs. It can also damage important genes that control the growth of cells, causing them to grow abnormally or to reproduce too quickly. This lead to various types of cancer such as; mouth, throat, gastric, kidney, bladder, cervical, pancreatic and lung cancer.
Lastly, cigarette smoking during pregnancy increases the risk of low birth weight, prematurity, abortion, perinatal mortality in humans and infertility. After birth, the risk for sudden infant death syndrome doubles for babies exposed to second hand cigarette smoking. Babies whose mother smoked in the first trimester of pregnancy are more likely to have a heart defect at birth. Undersize babies tend to have underdeveloped bodies. Their lungs may not be ready to work on their own, which means they may spend their first days or weeks attached to a respirator. After they're breathing on their own (or even if they did from the start), these babies may have continuing breathing
