Humans have three life processes:
nutrition, interaction and reproduction.

OUR DIGESTIVE SYSTEM
The mouth, the esophagus, the stomach and the intestine are part of our digestive system.

THE PYRAMID FOOD

OUR RESPIRATORY SYSTEM
The nose, the windpipe and the lungs are part of our respiratory system.

OUR CIRCULATORY SYSTEM The heart and the blood vessels are part of our circulatory system.

OUR EXCRETORY SYSTEM
Our excretory system helps us get rid of waste products. The kidneys, the ureters, the bladder and the urethra are part of our
excretory system.

OUR REPRODUCTIVE SYSTEM
Our reproductive system allows us to have babies. the fetus grows inside the uterus.
