Abdominal Quadrants and Structures - Anatomy Practical 1

NAU OTD

Liver

URQ

Metabolic regulation, synthesis of bile, detoxify blood

purple structure

Gallbladder

Stores and concentrates bile from the liver

URQ - Posterior to liver

Ascending Colon

Absorbs water, salt, minerals from the waste material

RLQ

Small Intestine

Digestion and absorption of nutrients

RLQ/LLQ

Appendix

No longer plays evolutionary role as it did in herbivores.

RLQ

Spleen

Organ of the immune system and plays role in immunological defense

LUQ - posterior and lateral to stomach

Stomach

Sterilization of food, physical and enzymatic digestion, temporary storage of masticated food

URQ

Transverse Colon

Absorbs water, salts, and minerals from the waste material; more solid than in the ascending colon before

Descending Colon

Absorbs remaining water and essential vitamins and solidifies waste

LLQ

Urinary Bladder

Stores urine from kidneys

Pancreas

Exocrine = digestive enzymes sent to the duodenum

Endocrine = hormones that control blood sugar and GI activity

ULQ/URQ

Kidney

Excretion of liquid waste, influences blood pressure, red blood cell formation, and electrolyte balance
