Cardiovascular and Lymphatic Systems and Viral Diseases
The
cardiovascular system
consists of the heart, and blood vessels. The lymphatic system consists
of the lymph, lymph nodes, and the lymphoid organs (tonsils, appendix,
and thymus gland).

心血管系统主要结构与功能
STRUCTURE
AND FUNCTION OF THE CARDIOVASCULAR SYSTEM
心血管系统的核心是心脏。心血管系统的功能是使血液在体内的各种组织中循环，将各种各样的物质输送到各类细胞处，将细胞的其他物质运走。
The center of the cardiovascular system is the heart. The function of the cardiovascular system is to circulate blood through the body's tissues so it can deliver certain substances to cells and remove other substances from them.

血液是各种成形物质和血浆的混合物。血浆将各种溶解的营养物质运输到机体的细胞并将细胞的废弃屋运走。血液内的成形物质包括红细胞、白细胞、血小板等。红细胞可以携带氧气和一些二氧化碳，虽然血液中多数二氧化碳是溶解在血浆里的。白细胞有保护机体抵抗感染方面有多种作用。部分白细胞，尤其中性粒细胞，是吞噬细胞。B细胞和T细胞这两种淋巴细胞在机体的免疫中发挥重要的作用。
Blood is a mixture of formed elements and a liquid called plasma. The plasma transports dissolved nutrients to body cells and carries wastes away from. the cells. The formed elements in blood include red blood cells, white blood cells, and platelets. Red blood cells, or erythrocytes, carry oxygen and some carbon dioxide, although most of the carbon dioxide in blood is dissolved in the plasma. White blood cells, or leukocytes, play several roles in defending the body against infection. Recall that some white cells, particularly neutrophils, are phagocytes. B cells and T cells, two types of lymphocytes, play key roles in immunity.
erythrocyte [i5riWrEusait]n.[医]红血球
carbon dioxide
n.[化]二氧化碳
leukocytes n.白细胞
lymphocytes n.淋巴细胞
