Effects of Smoking

Smoking has numerous detrimental effects on respiratory health, including contributing to conditions like COPD, chronic bronchitis, and emphysema. Chronic bronchitis results in increased mucus production, leading to symptoms like cough, chest pains, and difficulty breathing.

Effects of Smoking

Effects of Smoking

Nicotine

nervous system
release adrenaline
affects neurotransmitters in the brain
addictive
reproductive system
babies have low birth weights/ born prematurely/ increase risk of lung problems
increase infertility and miscarriage
prohibits proper blood circulation causing impotence
cardiovascular disease
reduce diameter of arterioles

in oxygen supply

heart rate and blood pressure

aneurysm
stroke
heart attack
cause blood clotting

Carbon Monoxide

Diseases
Stroke
Coronary heart disease/ atherosclerosis

causes high blood pressure, heart attacks, strokes

hinders blood flow

plaque builds up in arterties

Symptoms
Mimics influenza

fatigue

nausea

vomiting

mental confusion

rapid heart rate

dizziness

headache

Effects
Injure fetus upon exposure
Reduction of blood flow
Build up of fatty tissue
Damage lining of the arteries
Puts a strain on heart muscle
Decreases quantity of oxygen transported in the blood
Mode of action
4. CO is faster at binding with Hb than oxygen and exits the body slower
3. Oxygen cannot bind to receptors on cells that contain carboxyhaemoglobin
2. Combines with haemoglobin to form carboxyhaemoglobin
1. Diffuses into RBC

Tar

Lung Cancer
spread through bronchiole epithelium & enter lymphatic tissue in lungs
react with DNA in epithelial cells to produce mutation & leads to development of tumour
COPD
Emphysema

Emphysema treatment

Long term outlook

Quitting smoking

Alternative therapies

Sulfur has been identified as an aid in reducing inflammation and mucus.

Chinese herbs like ginkgo biloba which helps strengthen the lungs

Surgery and rehabilitation

Some people with emphysema may qualify for surgery to reduce lung volume, which helps to decrease symptoms.

Oxygen supplementation

Oral treatments

Oral steroid like prednisone is prescribed to people in addition to using an inhaler.

Medications as inhalants

Bronchodilators are medications that relax the bronchiolar muscles and improve airflow.

Effects on emphysema

People with severe emphysema often need a continuous supply of oxygen through a face mask.

wheezing occurs and breathlessness becomes progressively worse

Lung function deteriorates

It is a condition in which bronchioles collapse, leaving large spaces where surface area for gaseous exchange used to be

Large spaces appear where alveoli have burst

Less oxygen absorbed to blood

Number of capillaries decreases

Reduces surface area for gas exchange

Protein digesting enzyme known as elastase is released

Destroys elastin in the walls of the alveoli (allowing phagocytes to enter and remove bacteria)

Phagocytes line the airways

Chronic Bronchitis

-accumulation of mucus

difficulty breathing

drowsiness

chest pains

pneumonia

smoker's cough

-cleaning action inhibited

-stimulate goblet cells & mucous glands to secrete more mucous
