Science
| Question | Answer |
|---|---|
| Transport involves ____________ and _____________. | Absorption, circulation. |
| Another name for the circulatory system. | Cardiovascular system. |
| Blood transports _________________,_ _________________, _______________, ______________, and ______________ | Oxygen, carbon dioxide, nutrients (glucose and amino acids), wastes, and hormones. |
| A fluid that flows through the vessels of the circulatory system. | Blood. |
| Four life processes blood is involved in. | Transportation, regulation, protection, and homeostasis. |
| Liquid portion of the blood. | Plasma. |
| Function of red blood cells. | Transport oxygen from the lungs to the body tissues and carbon dioxide from the body tissues to the lungs. |
| Where are red blood cells made? | Bone marrow. |
| Iron-containing pigment found in red blood cells, gives blood its red color and helps with the transport of carbon dioxide and oxygen. | Hemoglobin. |
| Lack of red blood cells. | Anemia. |
| Another name for white blood cells. | Leukocytes. |
| Function of white blood cells. | Protect the body against infection caused by bacteria and other microorganisms. |
| White blood cells that engulf and destroy bacteria at the site of an infection through phagocytosis. | Phagocytes. |
| White blood cells that produce antibodies that react with an antigen and inactivate it. | Lymphocyte. |
| Disease-causing organism. | Pathogen. |
| Function of platelets. | Form blood clots. |
| Shape of platelets. | Tiny, irregularly shaped. |
| A plasma protein that forms a net over the wound to trap blood cells and forms a clot. | Fibrin. |
| True or False: Red blood cells are larger than white blood cells. | False, white blood cells are larger than white blood cells. |
| Shape of a red blood shell. | Disk-shaped, dent in the middle. |
| Which system is responsible for transport? | Circulatory system. |
| Process by which substances move into or out of cells or are distributed within cells. | Transport. |
| True or False: The human circulatory system is a closed system because blood is located in vessels. | True. |
| Three types of vessels. | Veins, arteries, and capillaries. |
| Where do arteries carry blood? | Away from the heart. |
| How do arteries expand and contract? | Your pulse, or heartbeat. |
| Largest artery. | Aorta. |
| True or False: Arteries are very thin and typically weak. | False, they are thick and muscular because of the forceful pump of blood from the heart. |
| Where do veins bring blood? | To the heart. |
| True or False: Veins are thin and long. | True. |
| Veins contain _____________ that stop blood from flowing backwards. | Valves. |
| Flap-like tissues that allow the blood to flow in only one direction, towards the heart. | Valves. |
| Which type of blood flows in most veins? | Deoxygenated blood. |
| The smallest blood vessel that is only one cell thick. | Capillaries. |
| Three functions of capillaries. | Connect arteries to veins, exchange materials between blood and body tissues, diffusion. |
| Function of the heart. | Acts as a pump whose rhythmic contractions make blood flow through the vessels. |
| How many chambers does the heart have? | Four. |
| Upper chambers of the heart. | Atria. |
| Lower chambers of the heart. | Ventricles. |
| Separates oxygenated from de-oxygenated blood. | Septum. |
| Trick to figure out which side of the heart has oxygen and which does not. | Dr. Lo. |
| Largest vein. | Vena Cava. |
| Type of circulation that involves carrying blood from the heart and lungs. | Pulmonary circulation. |
| Type of circulation that involves carrying blood between the heart and the rest of the body. | Systematic circulation. |
| Type of circulation that supplies blood to the muscles of the heart. | Coronary circulation. |
| Type of circulation that involves transport from the digestive tract to the liver. | Hepatic portal circulation. |
| Type of circulation that involves to and from the kidney. | Renal circulation. |
| Type of circulation that involves returning intracellular fluid to the blood. | Lymphatic circulation. |
