The human body is made up of systems working together. We recognize eleven. All of the systems include several organs. Each system works with other systems to sustain life. The
____________________ system consists of the hair, skin (dermis and _________), and nails.
________ is the largest organ of the body making up about 15% of your body weight. The
__________________ system supports the body and gives it structure. Blood cells are also made in the marrow of the bones. ___________ are stored within the bones. The
_____________ system rids the body of the wastes in the blood. This system consists of the skin
(sweat), lungs (CO
2
), kidneys, ureters, bladder, and the urethra (urea and water). The
_____________ system circulates deoxygenated and oxygenated blood around the body. Within the blood, nutrients, oxygen, and carbon dioxide are brought to the cells and lungs. The heart, veins, arteries, and capillaries help comprise the parts of this system. The _________________
system helps provides movement to the body through the contraction of actin and ___________ fibers. It is made of voluntary (skeletal), cardiac, and involuntary (smooth) muscle. Smooth muscle assists in moving food through the digestive tract through a process called _____________. The
_____________ system helps break down and absorb nutrients into the blood. It consists of the mouth, esophagus, stomach, pancreas, small intestines, large intestines, anus, and liver. Nutrients are absorbed by _________ in the small intestines. Water is mostly absorbed in the __________ intestines. The _________________ system consists of glands that produce hormones which travel through the blood to target organs. Examples of these hormones are human growth hormone and testosterone. The ______________ system is responsible for coordinating all actions of the body whether involuntary or voluntary. It uses electrical impulses to signals parts of the body to do specified jobs. The brain, spinal cord, and neurons comprise the bulk of this system. The cells that are responsible for sending or receiving messages are called _____________. They consist of a dendrite, cell body, and axon. The ________________ system helps remove CO
2
from the body and bring O
2
into the body. It consists of the nose, trachea, bronchi, bronchioles, and alveoli.
The ___________________ system allows humans to reproduce through the joining of sperm and egg to form a zygote. The penis, testicles, vagina, uterus, and ovaries are examples of organs within this system. The ____________ system helps fight off pathogens. The T-cells and B-cells help to destroy pathogens and create antibodies so that they body recognizes foreign invaders.
_________ are nonliving entities that reproduce inside of specific cells of the body, dependent on what it is. HIV hijacks immune system cells. Rabies hijacks cells of the nervous system. Influenza

Body Systems and Disease hijacks cells of the digestive system. They reproduce through either lysogenic or ________ cycles which destroy the cell. ___________ are living pathogens that infect the body. They reproduce through binary fission which can occur every 20 minutes. Since they are living, they can be killed by using ______________.
