| Question | Answer |
|---|---|
| Trachea | Tube that allows passage of air to the lungs; produces mucus |
| Larynx | Protects the trachea, responsible for sound, involved in swallowing |
| Bronchi | Divided by the trachea, a caliber of the airway in the respiratory tract |
| Lungs | Essential respiration organs, where gas exchange occurs |
| Diaphragm | Separates thoracic from abdominal cavities, contracts/relaxes for breathing |
| Esophagus | passes food from pharynx to the stomach |
| Stomach | kills ingested bacteria, begins food breakdown, releases food at a constant rate |
| Rugae | ridges of tissue in the stomach that increase surface area |
| Pyloric sphincter | region of the stomach that connects to the duodenum |
| Small intestine | organ where most digestions takes place |
| Duodenum | first part of the small intestine, where most chemical digestion takes place |
| Jejunum | muscular part of the small intestine which helps move food along, between duodenum and ileum |
| Ileum | final portion of the small intestine, absorbs certain vitamins and salts and whatever else the beginnings of the small intestine missed |
| Large intestine | wider and less muscular, where water is extracted and salt is taken from solid waste (consists of cecum and colon) |
| Rectum | temporary storage facility for feces |
| Anus | where feces are expelled |
| Liver | detoxifies, makes proteins, produces bile |
| Gall bladder | aids in digestion and concentrates bile |
| Bile duct | any long tube-like structure that carries bile |
| Pancreas | produces hormones and juice for digestion |
| Kidney | includes a cortex and a medulla, maintains homeostatic balance of body fluids |
| Ureter | propels urine from kidney to urinary bladder |
| Bladder | collects urine prior to disposal by urination |
| Urethra | tube that takes urine out of the body |
| Ovaries | produces ovum and hormones |
| Oviducts | aka fallopian tubes, transport eggs from ovary to the uterus |
| Uterine Horn | point where the uterus and oviducts meet |
| Testes | produces sperm and hormones |
| Epididymis | connects testes to the vas deferens |
| Vas Deferens | transports sperm in anticipation of ejaculation |
| Urethra | passes urine (or sperm in males) to outside the body |
| Gubernaculum | Attach peritoneum to the gonads |
| Thymus | where T-lymphocytes mature, just behind the sternum |
| Thyroid | butterfly controls how quickly body burns energy, makes proteins, hormones |
| Pancreas | produces hormones and juice for digestion |
| Testes | produce sperm and sex hormones |
| Cerebral cortex | key role in memory, attention, awareness, language, thought, etc... |
| Corpus callosum | white matter that connects left and right cebrebral hemispheres |
| Cerebellum | responsible for sesnory perception, coordination, and motor control |
| Medulla | deals with autonomic functions like breathing and blood pressure |
| Optic chiasm | part of the brain where the optic nerves partially cross |
| Thalamus | processes and relays sensory information, involved in sleep vs wakefulness |
| Hypothalamus | links nervous system to the endocrine system via the pituitary gland |
| Pituitary glad | very important gland that regulates many aspects of homeostasis, connected to the hypothalamus |
| Pons | relays sensory and other information between the cerebellum and cerebrum |
