Organs of the Human Body

Nervous System

• Controls all bodily functions, interprets and processes sensory information, and enables thinking, learning, and emotions.

Circulatory System

• Pumps blood throughout the body, delivering oxygen and nutrients to cells and removing waste products.

Respiratory System

• Facilitates the exchange of oxygen and carbon dioxide during breathing, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled.

Digestive System

Liver

• Performs various functions including detoxification of blood, synthesis of proteins, production of bile for digestion, and storage of nutrients.

Stomach

• Digests food by mixing it with stomach acid and enzymes, breaking it down into smaller molecules for absorption.

Pancreas

• Produces digestive enzymes and hormones such as insulin and glucagon, which regulate blood sugar levels.

Small Intestine

• Absorbs nutrients from digested food into the bloodstream, including carbohydrates, proteins, fats, vitamins, and minerals.

Large Intestine (Colon)

• Absorbs water and electrolytes from undigested food, forms and stores feces, and facilitates the elimination of waste from the body.

Excretory System

Kidneys

• Filter blood to remove waste products and excess substances, regulate fluid and electrolyte balance, and produce urine.

Integumentary System

Skin

• Acts as a barrier to protect the body from external threats, regulates body temperature, and contains sensory receptors for touch, pressure, temperature, and pain.
