Human organs

This glossary provides a comprehensive alphabetical list of human organs along with their associated systems, functions, and visual references.

A

• Adrenal glands – Located above the kidneys, these glands produce hormones such as adrenaline and cortisol as part of the endocrine system.

Adrenal glands

• Anal canal – The final section of the digestive system through which waste exits the body.

• Arteries – Blood vessels that carry oxygenated blood away from the heart to the rest of the body.

B

• Bladder – A hollow organ in the urinary system that stores urine before excretion.

Bladder

• Bone marrow – Found in the interior of bones, it produces blood cells.

• Brain – The central organ of the nervous system responsible for thought, memory, emotion, and other bodily functions.

Brain

C

• Capillaries – Tiny blood vessels that facilitate the exchange of oxygen, nutrients, and waste products between blood and tissues.

• Cervix – The lower part of the uterus connecting to the vagina in the female reproductive system.

• Cornea – The transparent front part of the eye covering the iris and pupil.

D

• Duodenum – The first section of the small intestine, where most digestion begins.

E

• Esophagus – A muscular tube transporting food from the pharynx to the stomach.

Upper esophagus

F

• Fallopian tubes – Tubes in the female reproductive system that transport eggs from the ovaries to the uterus.

G

• Gallbladder – A small organ beneath the liver that stores and releases bile.

Gallbladder

• Ganglia – Clusters of nerve cells in the peripheral nervous system.

• Heart – The central organ of the circulatory system, pumping blood throughout the body.

Heart

H

• Hypothalamus – A region of the brain regulating hormones, temperature, and hunger.

I

• Ileum – The final section of the small intestine involved in nutrient absorption.

• Intestine – Includes the small intestine and large intestine for digestion and nutrient absorption.

J

• Jejunum – The middle section of the small intestine, where the majority of nutrient absorption occurs.

K

• Kidneys – Bean-shaped organs in the urinary system that filter blood and produce urine.

Kidneys

L

• Large intestine – Includes sections such as the cecum, colon, and rectum, involved in water absorption and waste elimination.

• Larynx – The voice box, part of the respiratory system responsible for sound production.

Larynx

• Liver – A vital organ involved in metabolism, detoxification, and bile production.

M

• Mammary glands – Specialized glands in the integumentary system that produce milk.

Mammary glands

• Mesentery – A tissue fold anchoring the intestines to the abdominal wall and supplying them with blood.

N

• Nasal cavity – The upper part of the respiratory system, filtering and humidifying air.

Paranasal sinuses

• Nerves – Bundles of neurons transmitting signals between the brain and the rest of the body.

O

• Ovaries – Organs in the female reproductive system producing eggs and hormones like estrogen and progesterone.

P

• Pancreas – An organ with endocrine and exocrine functions, secreting insulin and digestive enzymes.

Pancreas

• Pharynx – Part of both the digestive and respiratory systems, connecting the mouth and nasal cavity to the esophagus and trachea.

Pharynx

R

• Rectum – The final section of the large intestine that stores feces before elimination.

• Respiratory system – Includes organs like the lungs, trachea, and larynx.

S

• Skin – The largest organ of the integumentary system, providing protection and temperature regulation.

• Small intestine – Primary site of digestion and nutrient absorption, comprising the duodenum, jejunum, and ileum.

• Stomach – A muscular organ in the digestive system breaking down food with acid and enzymes.

T

• Thymus – Part of the lymphatic system, playing a role in immune system development.

• Thyroid gland – Produces hormones regulating metabolism.

Thyroid gland

U

• Ureter – Tubes carrying urine from the kidneys to the bladder.

• Urethra – A tube transporting urine from the bladder out of the body.

• Uterus – A hollow organ in the female reproductive system where a fertilized egg develops into a fetus.
