| Term | Definition |
|---|---|
| Cell Organization | Cells come in many different shapes and sizes. A cells shape is determined by its function. |
| Tissues | A tissue is a large group of similar specialized cells. A tissue gets its characteristics from the type of cell that forms it. |
| Organs | Organs are formed from tissue. An organ is a group of related tissues that perform a specific function. Even if two organs are made of the same tissue they can be different in appearance and function. |
| Organ Systems | Organs are organized into organ systems. Organ systems are related organs that work together to perform a specific function. Organ systems combine to form the entire organism. |
| Circulatory System | Responsible for bringing oxygen and nutrients to all cells. It also takes carbon dioxide and wastes away from cells. Main parts include: the heart, arteries,veins,and capillaries. The heart pumps blood to parts of your body. The arteries carry blood away |
| Respiratory System | Responsible for bringing oxygen to the blood. Main parts include: the bronchial tube, lungs,alveoli,and the diaphragm. The alveoli transfer oxygen into surrounding capillaries and in return the alveoli receive carbon dioxide. When you inhale, your diapgra |
| Digestive System | Responsible for breaking down food into simpler substances. The main parts include:salivary glands,esophagus,stomach,liver, pancreas,small and large intestine. Food starts to break down in the mouth, with chewing and saliva.Then it passes from the esophag |
| Nervous System | Responsible for recieving and processing information.It also controls how the body reacts and moves.The main parts include: the eyes,brain,and spinal cord.Specialized cells called neurons send electrical impluses to different parts of your body.The brain |
| Muscular and Skeletal System | The muscular system allows your body to do many things, while the skeletal system provides shape,support,and protects your organs.Smooth muscle tissue controls your breathing, blood pressure,and digestive functions.Cardiacmuscle is only found in the heart |
| Endocrine System | Responsible for regulating hormones release to the different parts of the body.The main parts include: thyroid gland,adrenal glands,and the pancreas.The thyroid gland controls the body metabolism.The adrenal glands are involved in the body's situations. |
| Excretory System | Responsible for removing wastes from the body. Main parts include: Kidneys,bladder and colon. The Excretory system removes waste from the digestive system and blood. |
| Other Systems |
