Flashcards

Mouth

Where food intake and initial digestion (through chewing and saliva) occur.

Esophagus

The tube that connects the mouth to the stomach, allowing food to pass.

Stomach

A muscular organ where food is mixed with digestive enzymes and acids to break it down.

Small Intestine

The site of most nutrient absorption. It includes the duodenum, jejunum, and ileum.

Study Notes

  • These are notes on the systems of the human body

Digestive System

  • Mouth: food intake and initial digestion occur
  • Esophagus: connects the mouth to the stomach, allowing food to pass.
  • Stomach: food is mixed with digestive enzymes and acids to break it down.
  • Small Intestine: most nutrient absorption happens here, includes the duodenum, jejunum, and ileum.
  • Large Intestine: absorbs water and salts, forming stool.
  • Liver: produces bile to digest fats and processes nutrients.
  • Pancreas: produces digestive enzymes and insulin to regulate blood sugar.
  • Gall Bladder: stores bile from the liver and releases it to aid in digestion.

Endocrine System

  • Pancreas: regulates blood sugar by releasing insulin and glucagon.
  • Thyroid: produces hormones that regulate metabolism, energy, and growth.
  • Adrenal Glands: produce hormones like adrenaline and cortisol that help manage stress and regulate metabolism.

Integumentary System

  • Skin: protects the body, regulates temperature, and allows sensations like touch.

Excretory/Urinary System

  • Kidneys: filter waste from the blood and produce urine.
  • Bladder: stores urine.
  • Ureters: carry urine from the kidneys to the bladder.
  • Urethra: urine is expelled from the body through this.

Nervous System

  • Brain: control center of the body.
  • Eyes: vision.
  • Cerebellum: part of the brain that helps coordinate movement and balance.

Muscular System

  • Muscles: movement and posture.

Skeletal System

  • Bones: structure, protect organs, and store calcium.
  • Joints: where two bones meet, allowing movement.
  • Cartilage: cushions joints and supports certain structures.

Circulatory System

  • Heart: pumps blood.
  • Blood Vessels: transport blood.
  • Blood: carries oxygen, nutrients, and waste.

Respiratory System

  • Lungs: facilitate gas exchange.
  • Trachea: carries air to the lungs.

Reproductive system

  • Testes: produce sperm and testosterone.
  • Ovaries: produce eggs and hormones like estrogen.
  • Uterus: where a fertilized egg grows during pregnancy.
