Prepare yourself for an interactive biology pop quiz that challenges your understanding of the circulatory and immune systems! Bring a clicker and a piece of paper for notes—just in case! From questions about artery structure and oxygenated blood flow to the role of vaccines and immune cells, this quiz covers key concepts in physiology. Use your knowledge on gas exchange, blood components, and immunology to score well. Are you ready to put your biology skills to the test?
E N D
Pop Quiz! Have your clicker ready. Get out a piece of paper, too, in case of technological hiccups.
Are you here today? • Yes.
Is it summer yet? • Alas, no.
1. Arteries are thick-walled because: • They carry blood at high pressure. • They must allow for gas exchange. • They must move blood up the legs toward the heart. 30 Countdown
2. Where would you expect to find oxygenated blood? • Right atrium • Pulmonary arteries • Left ventricle • Superior vena cava 30 Countdown
3. The vessel(s) carrying oxygenated blood out of the heart: • Superior and inferior vena cavae • Pulmonary arteries • Pulmonary veins • Aorta 30 Countdown
4. Most oxygen found in the blood stream is: • Dissolved in the plasma. • Bound to hemoglobin. • Taken up by white blood cells. • Bound to carbon. 30 Countdown
5. In fish and mammals, gas exchange is made efficient by: • Concurrent exchange. • Low diffusion gradient. • Counter current exchange. • Active transport. 30 Countdown
6. The cells of the immune system that produce antibodies are: • T-helper cells • T-killer cells • B-plasma cells • Macrophages 30 Countdown
7. How do vaccines work? • They destroy pathogens. • They stimulate the production of antibodies. • They increase the number of white blood cells. 30 Countdown
8. Mast cells stimulate inflammation by releasing: • Histamines • Antibodies • Phagocytes • Lysozymes 30 Countdown
