Before You ReadIn this section, you will find out about the systems of the human body. A system is madeof two or more parts that work together as a whole. If one of the parts is missing ordamaged, a system will not work well. It might not work at all. On the lines below, nameone type of system in your home. Give an example of what might happen if one part ofit is damaged.

What parts make up each system of the humanbody?

There are 11 systems of the body. Each of these systems ismade up of different parts that work together as a whole toperform all the functions that keep you alive. The parts thatmake up each body system are cells, tissues, organs, andorgan systems.

What is tissue?

Cells that have the same structure and that play the same rolein the body are grouped together to form tissue. For instance,muscle cells are grouped to form muscle tissue. ●✔

What is an organ?

Tissues of different kinds that work together form an organ.For instance, the heart is an organ. The heart is mostly madeof muscle tissue. Nerve tissue transfers signals to the heartfrom the brain and from other parts of the body. Epithelialtissue lines the inside of the heart and covers the outside of it.

Connective tissue gives strength and shape to the othertissues that form the heart. Muscle tissue, nerve tissue,epithelial tissue, and connective tissue are also found in otherorgan systems. ●✔

What is an organ system?

An organ can work by itself or it can work together withother organs to form an organ system. The heart is the onlyorgan in the circulatory system. The digestive system hasseveral different organs, including the stomach, the smallintestine, and the large intestine. The organs of the digestivesystem work together to help you take in food, break it down,absorb nutrients, and remove solid wastes from your body.

Systems in the Human Body

Circulatory– moves blood,

nutrients, gases, andwastes

Digestive– takes in and breaks

down food, absorbsnutrients, gets rid ofsolid waste

Respiratory– controls breathing and

exchanging gases inlungs and tissues

Excretory– removes liquid and

gas wastes

Immune– defends the body from

infections

Endocrine– makes hormones

Reproductive– has organs for

making babies

Integumentary(skin, hair, and nails)– protects the body

Skeletal– has bones that support

the body and work withmuscles to move thebody

Muscular– has muscles that

work with bones tomove the body

Nervous– has nerves that detect,

signal, and respond tochanges in the environment
