Excretory System By: Michael Buchheister & Grant Lemmer Lungs Kidneys Ureters Urethra Bladder Skin Urinary System Diagram:



Kidneys:

Skin: It could cause lung cancer.
You could get a lung replacement.
You can have black tar spots on your lungs from smoking. Smoking causes intense sympathetic excitation.
Paralleled by an increase in blood pressure.
Vasoconstriction is noted in many vascular beds, i.e. the coronary circulation or the forearm. Ureteral neoplasm, a type of tumor that can be primary, or associated with a metastasis from another site.
Urethral cancer, cancer of the urethra.
Urothelium, the tissue layer that lines much of the urinary tract, including the renal pelvis, the ureters, the bladder, and parts of the urethra. The urethra is the tube in a person's body that empties urine from the bladder.
In women, the urethra is a very short tube that opens to the outside of the body just above the bladder.
Where as in men it is a much longer tube that goes through the prostate gland and bladder to the outside of the body. Tobacco smoking is the main known cause of urinary bladder cancer in humans.
In most populations, over half of cases in men and a sizeable proportion in women are attributable to this habit.
Epidemiological studies conducted in different populations have shown a linear relationship between intensity and duration of smoking and risk. Damage to skin from smoking shows up as wrinkles, lines, crow's feet around the eyes, dryness, and a coarse and weathered look.
Smoking also causes skin to droop due to loss of elasticity and causes a gray or yellow complexion and a gaunt appearance.
Even in a smoker in her 20s, healthy glowing skin is replaced by these signs of premature aging.
