Blood

Haemoglobin, a globular proteingreen = haem groupsred & blue = protein subunits

Blood is a bodily fluid in animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.

In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains dissipated proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets. The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is almost entirely transported extracellularly dissolved in plasma as bicarbonate ion.

单词	Oxygen consumption
释义	Oxygen consumption 原声例句经济学人-科技 The combined level of oxygen consumption when the fish and anemone were together was significantly higher than when they were kept apart. 当小丑鱼和海葵共存时二者加在一起的耗氧量远高于比它们分开时的耗氧量之和。历年考研英语完形填空真题 Laughter does produce short-term changes in the function of the heart and its blood vessels, boosting heart rate and oxygen consumption. 笑确实会引起心脏及其血管功能的短期变化，从而提高心率和耗氧量。 BBC 听力 2016年8月合集 Inside the capsule, the miners' heart rate, temperature and oxygen consumption is monitored and they can speak to controllers on the surface. 在救生舱里，旷工的心率、体温和耗氧量被监控着而且他们可以和地面上的控制者交谈。健身知识科普 Now, HIIT advocates, including myself, would say that wouldn't matter much because HIIT also increases something known as EPOC, excess post-exercise oxygen consumption. 现在，包括我在内的 HIIT 提倡者会说这不怎么重要，因为 HIIT 还增大了一个指标 EPOC，即运动后的过量氧耗。健身知识科普 Using your heart rate, along with your age, height and weight, we can determine a close estimate of one's VO2, or oxygen consumption, which itself can be used as an estimate in calculating calorie expenditure. 根据你的心率，以及你的年龄、身高和体重，我们可以确定一个人的 VO2 或氧气消耗量的接近估值，氧气消耗量本身可以用作计算卡路里支出的估计。英语百科 Blood Blood is a bodily fluid in animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.
