 Cardiovascular system | A collection of organs that transport blood throughout the body. |
| Artery | a blood vessel that carries blood away from the heart to the body's organs |
| Capillary | A tiny blood vessel that allows an exchange between blood and cells in tissue |
| Vein | In biology, a vessel that carries blood to the heart |
| Pulmonary circulation | The flow of blood from the heart to the lungs back to the heart through the pulmonary arteries, capillaries, and veins |
| Systemic circulation | The flow of blood from the heart to all parts of the body and back to the heart |
| Blood | The fluid that carries gases, nutrients, and waste through the body and that is made of platelets, white blood cells. red blood cells, and plasma |
| Blood Pressure | The force that blood exerts on the walls of the arteries |
| Respiration | In biology, the exchange of oxygen and carbon dioxide between living cells and the environment; includes breathing and cellular respiration |
| Respiratory System | A collection of organs whose primary function is to take in oxygen and expel carbon dioxide |
| Pharynx | The passage from the mouth to the larynx and esophagus |
| Larynx | The area the throat that contains the vocal cords and produces vocal sounds |
| Trachea | The tube that connects the larynx to the lungs |
| Bronchus | One of the two tubes that connect the lungs with the trachea |
| Alveolus | Any of the tiny air sacs of the lungs where oxygen and carbon dioxide are exchanged |
| What makes up the cardiovascular system? | Your heart, blood, and blood vessels make up your cardiovascular system |
| What is homeostasis? | A state of stable internal conditions |
| Where is your heart located in your chest? | It is almost in the center of your chest |
| What are the two types of circulation? | Pulmonary circulation and systemic are the two types of circulation |
| What is plasma? | Plasma is a mixture of water, minerals, nutrients, sugar, proteins, and other substances |
| What are platelets? | Platelets are pieces of larger cells in bone marrow |
| What are vocal cords? | The vocal cords are a pair of elastic bands that stretch across the larynx |
| What happens in cellular respiration? | Oxygen is used by cells to release energy stored in molecules of the sugar glucose |
| What is systolic pressure? | Systolic pressure is the pressure inside large arteries when the ventricles contract |
| What is diastolic pressure? | It is the pressure inside the arteries when the ventricles relax |
