Answer |
| Endocrine System | Glands that secrete hormones and chemical substances that regulate body activities such as growth, reproduction and water balance. |
| Circulatory System | This system pumps and transports blood throughout the body. Blood carries nutrients and oxygen to all the body's cells and also carries the waste away from the cells to the organs of excretion. |
| Lymphatic System | Lymph and lymphoid structures play an important role in the defense of the body against pathogens and other foreign material. |
| Respiratory System | Conduct air to and from the lungs. Oxygen moves into the lungs and CO moves out of the lungs. |
| Digestive System | Organs designed to eat food, break it down into substances that can be absorbed by the body and eliminate the waste. |
| Urinary System | The urinary system helps control the amount and composition of water and other substances in the body. Help excrete waste products from the body through the urine. |
| Reproductive System | Has organs and structures that enable the human organism to reproduce. |
| Homeostasis | Means staying the same. |
| Homeostatic mechanisms | Mechanisms that help maintain homeostasis. |
| Homeostatic imbalance | When homeostatic mechanisms do not work normally disease or dysfunction |
| Sagittal plane | Divides the body lengthwise into right and left portions. Midsagittal section if cut is made excatly down the midline of the body. |
| Frontal plane | Divides the body into ventral and dorsal portions. Coronal plane |
| Transverse Plane | divides the body horizontally creating and upper and lower body. Cross section. |
| Two major cavities | Dorsal and ventral cavity |
| Cranial cavity | contains the brain |
| Spinal cavity | Contains spinal cord. |
| Thoracic cavity | Contains Lungs, heart, trachea, esophagus |
| Abdominopelivic cavity | Stomach, intestine, liver, gallbadder, spleen, kidneys. |
| Metabolism | All the chemical reactions that occur within the cells |
| What is ATP? | Energy-storing and energy-transferring molecule found in all cells. |
| What is an Atom | The fundamental unit of an element; the smallest part of the element that has the characteristics |
| Element | Substance composed of only one kind of atom |
| A compound containing nitrogen? | Protein |
| Most abundant compound in the body? | Water |
| Compunds forming ions in solution? | Cation, anions, and electroyles |
| Acid | Acid is an electrolyte that dissociates into a hydrogen ion and an anion |
| Cell | The basic unit of life |
| Cytoplasm | Gel-like substance surrounded by the cell membrane but outside of the nucleus. The area where most cellular activity occurs |
| Lysosomes | Housekeeping within the cell |
| Cytoskeleton | Provides for intracellular shape and support |
| Flagella | Create movement of cell |
