Influenza
A viral infection affecting the upper respiratory tract (which includes the nose, sinuses, throat and windpipe).
COMMON COLDS
is caused by bacteria (Mycobacterium tuberculosis)
Infection destroys patients’ lung tissue, causing them to cough up the bacteria, which then spread through the air and can be inhaled by others
TUBERCULOSIS
a malignant tumor that begins in the lung.
caused by genetic damage to the DNA of cells in the airways, often caused by cigarette smoking or inhaling damaging chemicals
LUNG CANCER
About 6 meters long and consist of three parts:
Duodenum
Jejunum
ileum
SMALL INTESTINES
It is a complex organ composed of both endocrine and exocrine tissues that performs several functions.
PANCREAS
Processes the nutrients and detoxifies harmful substances from the blood.
produces an important digestive fluid called bile
LIVER
a large cavity that collects the urine as it is produced.
collecting the urine produced in the kidney and leading to a central “stem,” the ureter.
RENAL PELVIS
Extends from the base of the urinary bladder to the tip of the penis
Carries both urine and sperm
Sperm enters from the ejaculatory duct
URETHRA
Divided sac of skin outside the abdomen
Maintains testes at 3°C lower than normal body temperature to protect sperm viability
SCROTUM
Comma-shaped, tightly coiled tube
Found on the superior part of the testis and along the posterior lateral side
