Respiratory and Urinary Functions

Paranasal sinuses

Drain mucus into the nasal cavity 

Nasal cavity

Filters inhaled air

Nostrils (nares)

Pathway of airflow in/out of nasal cavity

Nasal conchae

Stir up inhaled air

Tonsils

Protect against pathogens

Auditory Tube

Equalizes air pressure

Larynx

Protects the glottis

Epiglottis

Cover glottis during swallowing

Vocal folds

Produce speech

Trachea

Carries air between the larynx and bronchi

Tracheal rings (tracheal cartilages)

Prevent collapse during inhalation. 

Primary (main) bronchi

Airflow enter lungs

Lungs

Breathing

Diaphragm

When contracts pulls the lungs inferiorly

Bronchiole

Delivers air to the gas-exchange surfaces of the lungs

Alveoli

Gas exchange

Kidney

Get rid of waste

Renal corpuscle

Producing pre-urine

Proximal convoluted tubule

Reabsorption of critical ions

Nephron loop (loop of Henle)

Allows the production of concentrated urine

Distal convoluted tubule

Reabsorb water

Collecting duct

Determines the final volume of urine

Minor calyx

Drains urine from a single renal papilla

Major calyx

Drains urine to the renal pelvis

Renal pelvis

Drains urine out of the kidney

Ureter

Transport urine from the kidneys

Urinary bladder

Temporary storage for urine
