| What does the Respiratory System comprise of? | The nose, larynx, airways and lungs. |
| URINARY SYSTEM | Primarily concerned with excretion of nitrogenous waste (urea in urine) but is also important for control of the pH and ionic concentrations of the blood. |
| What is the Urinary System comprised of? | The kidneys, ureters, urinary bladder, and urethra. |
| ENDOCRINE SYSTEM | Made up of a series of glands that maintain homeostasis. |
| What is homeostasis? | The relatively constant internal state of the body. |
| What else does the Endocrine System include? | The pituitary, thyroid, adrenal and endocrine pancreas glands. |
| REPRODUCTIVE SYSTEM | The male and female reproductive systems are concerned with the production and nurturing of the next generation. |
| What does the Reproductive System include? | Gonads- which produce sex cells, as well as associated glands – erectile tissue, the uterus and breasts. |
