What is the difference between diffusion and active transport? (diffusion doesn’t require energy) Which part of the blood makes up half its volume? (plasma) What blood type is the universal blood donor? (O) T/F: Blood can flow directly from the right to the left side of the heart. (False) T/F: Blood in the pulmonary vein is rich in oxygen. (True) Which type of cell has about 5 million cells per cubic mm of blood? (red blood cells) What is the chemical found in red blood cells that carries oxygen and carbon dioxide called? (hemoglobin) What do red blood cells look like? (donuts without the hole in the middle) What do white blood cells look like? (koosh balls) What do platelets look like? (irregularly shaped) What blood type is the universal receiver? (AB) What is the liquid part of the blood called? (plasma) What happens to your body if What is leukemia? (disease in you are anemic? (your cells which your body produces too can’t get enough oxygen to many immature white blood function normally) cells) What blood vessel allows blood to reach every cell in the body? (capillary) When returning from the body, which chamber does blood enter first? (right atrium) What is the leading cause of death in the United States? (heart disease) What blood vessel carries blood away from the heart? (arteries) Name 2 functions of the circulatory system. (takes waste away from body cells to kidneys, takes oxygen and nutrients to cells, takes carbon dioxide away from cells, fights infection) What blood vessel carries blood back to the heart? (veins) What carries blood back to the heart from the lower part of the body? (inferior vena cava) When blood lacking oxygen leaves the heart, where does it go, and how does it get there? (pulmonary artery takes it to the lungs) How long do white blood cells last? (a few days or months depending on if they are fighting infection) What does the positive or negative sign associated with your blood type stand for? (Rh factor) What blood types can someone with Type B receive in a transfusion? (B, O) What blood types can blood type O receive in a transfusion? (O) What blood types can blood type A donate to in a transfusion? (A, AB) What do platelets do? (help clot blood) What do white blood cells do? (fight bacteria and viruses) What do red blood cells do? (carry carbon dioxide and oxygen) What type of circulation is What type of circulation is described as the flow of blood described as the flow of blood to and from the tissues of the to and from all body organs heart? (coronary) and tissues? (systemic) What is the difference between arteries and veins? (arteries travel away from heart, veins travel back to heart) What is pulmonary circulation? (flow of blood through heart, to lungs, and back to heart) Why is it important to keep What is blood pressure? one’s blood pressure in a (force of blood on the walls of normal range? (guarantee that the blood vessels) oxygen can reach all cells in body) How many platelets can typically be found in 1 cubic mm of blood? (400,000) How many white blood cells can typically be found in 1 cubic mm of blood? (5,00010,000) How many red blood cells can typically be found in 1 cubic mm of blood? (5 million) What is sickle-cell anemia? (red blood cells are C-shaped, don’t travel easily through blood vessels, cause clots) Trace the blood through systemic circulation, the largest part of the circulatory system. Explain where the blood travels and what it carries, drops off, and picks up throughout the process. What is anemia? (blood can’t get enough oxygen to body cells, low levels of iron and hemoglobin in blood)
