Organs of the Human Body

Study Notes

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.
