1.可替换为fulfill, perform等其为实践，履行的意思。可见例句，“科学家们通过开展这个实验，探究出了氧气与二氧化碳的某些关系，结果令他们十分欣慰。”“By carrying out this experiment, scientists have explored some of the relationship between oxygen and carbon dioxide, and the results are very gratifying ...
capillary (毛细血管) are between the air and the blood. So oxygen easily diffuses from the air sacs through the walls into the blood, while carbon dioxide easily diffuses from the blood through the walls into the air sacs.When blood is sent to the lungs by the heart, it has come back...
Blood is a vital fluid in the body. It consists of water, blood cells, nutrients, body chemicals, oxygen and carbon dioxide. Blood is part of the cardiovascular system. Answer and Explanation:1 Veins carry blood to the heart. After blood has nourished all of the cells in the body, it ...
Which veins drain into the internal jugular vein, and are also visible in the carotid triangle? Which part of the circulatory system does body tissue exchange oxygen and carbon dioxide with the blood? 1. the heart 2. the arteries 3. the veins 4. the lungs 5. the capill...
capillaries) will widen to deliver more oxygen to your muscles and carry away waste products, such as carbon dioxide and lactic acid.───毛细血管扩张把更多氧气送入肌肉中并带走排泄物,如二氧化碳和乳酸。 What conclusions can we draw from this experience, and carry away and put into action?──...
The invention relates to a method for commissioning an internal combustion engine (10), the exhaust gas system (20) of which is equipped with an electrically heatable lambda sensor (24) and a catalytic converter (30) with an oxygen reser... P Stefan,CL Falk-Christian,M Michael 被引量: 0...

Plants need sunlight and water to carry out photosynthesis. What is the main product of photosynthesis? A. oxygen B. carbon dioxide C. water D. sunlight 相关知识点: 试题来源: 解析 A。本题考查光合作用的主要产物。光合作用是植物利用光能,将二氧化碳和水转化为有机物和氧气的过程,主要产物是氧气。
This is where oxygen and carbon dioxide exchange can occur. Once blood leaves capillaries, it enters into the other side of the circulatory system, which is made up of veins that return the blood back to the heart. Arteries (shown in red) carry blood away from the heart, while veins (...
In the lungs, the blood receives oxygen and releases carbon dioxide. 4. Contrasting with Other Arteries: Other arteries in the body, such as the coronary artery, hepatic artery, and systemic arteries, carry oxygenated blood. This highlights the unique role of the pulmonary artery. 5. Conclusion...
