Study Notes

Gastrointestinal System

Anus: The exit point of the digestive tract for waste expulsion.
Appendectomy: Surgical procedure to remove the appendix due to appendicitis.
Appendicitis: Condition characterized by appendix inflammation; requires urgent medical intervention.
Appendix: A small, functionally insignificant tube at the junction of the large and small intestine.
Colon: The last portion of the intestine, also known as the large intestine or large bowel; spans three to four feet, excluding the rectum.
Diaphragm: A dome-shaped muscle that separates the abdominal and thoracic cavities; its contraction increases chest volume.
Gallbladder: A pear-shaped organ located beneath the liver; functions to store, concentrate, and release bile for digestion.
Large Intestine: Comprising the ascending, transverse, descending, and sigmoid colon; absorbs water and electrolytes from the liquid contents received from the small intestine to form feces.
Liver: One of the largest organs with over 5,000 functions, crucial for various metabolic processes.

Genitourinary System

Urinary System: Eliminates waste like urea, which is formed during the protein breakdown (e.g., from meat and vegetables).
Kidneys: Bean-shaped organs located near the middle back; responsible for filtering blood and removing urea through nephrons.
Ureters: Two thin tubes (8 to 10 inches long) that transport urine from the kidneys to the bladder, utilizing muscular contractions.
Bladder: A hollow, muscular organ that resembles a balloon; positioned in the pelvis and supported by ligaments.
Sphincter Muscles: Muscles that tightly encircle the bladder's opening into the urethra, controlling urine passage outside the body.
