| Term | Definition |
|---|---|
| Alveoli | Spherical air sacs where gases pass into and from the blood |
| Artery | A blood vessel that carries blood from the heart to the body |
| Capillary | The smallest blood vessel. Gases, nutrients, and wastes are exchanged between capillaries and cells. |
| Circulatory System | The system of blood vessels and organs that transports blood to all cells in the body |
| Classify | To identify and organize according to similar properties or other criteria |
| Diaphragm | A large, flat, arched muscle that draws air in as well as pushes air out of the lungs. |
| Heart | A muscular organ that pumps blood. |
| Heart Valve | A regulator that moves blood in one direction, ensuring that it does not pump the wrong way in the system. |
| Leaf Vein | The branching network of tiny raised lines on the underside of a leaf. |
| Left Ventricle | The lower chamber on the left side of the heart. |
| Lung | The organ in animals where gases, such as oxygen and carbon dioxide, pass between the atmosphere and the blood. |
| Palmate | Describing a leaf in which several veins start at one point near the base. The veins look like fingers of a hand. |
| Parallel | Describing a leaf in which the veins are straight lines all running in the same direction. |
| Phloem | The long cells which nutrients, such as sugars, are distributed in a plant |
| Pinnate | Describing a leaf that has one main vein with smaller veins branching off sideways from it |
| Respiratory System | The system of lungs and connecting tubes that transports oxygen to the red blood cells and gets rid of carbon dioxide. |
| Right Ventricle | The lower chamber on the right side of the heart |
| Sap | A sugar-rich liquid transported by phloem |
| Transpiration | The process in which water is removed from the cells and passes into the enviornment |
| Vascular Bundle | The group of xylem tubes and phloem tubes in a vascular plant |
| Vascular System | Keeps fluids moving throughout the entire system, maintaining a moist (aquatic) environment for all cells |
| Vein | The blood vessel that carries blood from the body to the heart |
| Vital Capacity | The maximum volume of air a person can take into their lungs then expel |
| Xylem | The hollow cells of a plant that transport water and minerals to plant cells |
