血液循环机制英文作文

血液循环机制英文作文英文：Blood circulation is a fundamental process in the human body that ensures the distribution of oxygen, nutrients, and hormones to tissues and organs while removing waste products like carbon dioxide. It involves the heart, blood vessels, and blood itself.The process starts in the heart, where deoxygenated blood is pumped to the lungs via the pulmonary artery. In the lungs, carbon dioxide is released, and oxygen is absorbed into the blood. This oxygen-rich blood returns to the heart through the pulmonary vein.Once oxygenated, the blood is pumped out of the heart's left ventricle into the aorta, the body's largest artery. From there, it travels through smaller arteries and arterioles, reaching various tissues and organs. Along the way, oxygen and nutrients are delivered to cells, whilewaste products are collected.After passing through the arterioles, the blood enters tiny vessels called capillaries, where the exchange of gases, nutrients, and waste products occurs with surrounding cells. This exchange is vital for cellular function and tissue health.Following the exchange in the capillaries, the blood, now deoxygenated, enters venules and then veins, eventually returning to the heart's right atrium. The cycle repeats as the blood is pumped to the lungs for oxygenation and then back to the body.The circulatory system also plays a crucial role in regulating body temperature and maintaining homeostasis. For example, during exercise, blood flow increases to deliver more oxygen to muscles and remove heat generated by metabolism.Overall, blood circulation is a dynamic process that keeps the body functioning properly, ensuring cells receivethe necessary oxygen and nutrients while efficiently removing waste products.中文：血液循环是人体的基本过程之一，它确保了氧气、营养和激素被输送到组织和器官，同时排除像二氧化碳这样的废物。

• 动脉有节奏的收缩和扩张伴随着一次心跳 • 每一个心脏的收缩,称为收缩期，每个收缩期后跟一个放松阶段,心脏舒张期,在此期间心事被血液填满。每次心脏跳动时,心房立即收缩,此后两心室收缩
Blood Pressure
• Blood pressure is the force exerted by blood againt the wall of a blood vessel. • It is commonly measured in a large artery with a sphygmomanometer.Both systolic and diastolic pressure are measured and reported as systolic then diastolic separated by a slash,such as 120/80. • Blood pressure is a valuable diagnostic measurement that is easily obtained. • 血压是血液的流动时，撞击血管壁的所产生的力。 • 它通常用血压计测量在一个大的动脉。收缩压和舒张压都是测量和报告为收缩压舒张压一个斜杠隔开,如 120/80。 • 血压是一种有价值的诊断测量,很容易获得。

体循环的流程

体循环的流程The circulatory system is a crucial part of the human body, responsible for transporting oxygen, nutrients, and hormones to cells throughout the body. 体循环是人体的一个关键部分，负责将氧气、营养和激素输送到全身的细胞中。

One of the most important components of the circulatory system is the heart, which acts as a pump to circulate blood throughout the body. The heart is a powerful organ that contracts and relaxes to push blood through the blood vessels. It is made up of four chambers, each playing a specific role in the circulation process. The left and right atria receive blood from the body and lungs, while the left and right ventricles pump blood out to the body and lungs. Once the blood has been oxygenated in the lungs, it is pumped back to the heart to be distributed to the rest of the body. 循环系统中最重要的组成部分之一是心脏，它起着泵的作用，将血液在全身循环。

The lymphatic system is a widely distributed system with multiple functions. Its role in circulation is to return excess fluid and proteins from the tissues to the bloodstream. The fluid carried in the lymphatic system is called lymph. Another function of the lymphatic system is to absorb digested fats from the small intestine These fats are then added to the blood near the heart. One other major function of the lymphatic system is to protect the body from impurities and invading microorganisms.

Coronary heart disease (CHD) is a condition in which proper circulation of blood and oxygen are not provided to the heart and surrounding tissue. This result is due to a narrowing of the small blood vessels, which normally supply the heart with blood and oxygen. The typical cause of coronary heart disease is a condition known as atherosclerosis, which takes place with plaque and fatty build up on the artery walls, narrowing the vessels. Some more frequent symptoms of coronary heart disease include:

血液循环英文作文

血液循环英文作文英文：Blood circulation is an essential process in our body that enables the transportation of nutrients, oxygen, and waste products throughout the body. The circulatory system consists of the heart, blood vessels, and blood. The heart pumps oxygenated blood to the body through the arteries, and the deoxygenated blood is returned to the heart through the veins.The circulatory system is crucial for our body to function properly. For example, when we exercise, our muscles require more oxygen, and the heart pumps more blood to meet the demand. Similarly, when we are sick, our body produces more white blood cells to fight off infection, and the circulatory system helps to transport these cells to the affected area.However, there are also some factors that can affectthe blood circulation in our body. For instance, smokingcan cause the blood vessels to narrow, which can lead to poor circulation. Similarly, a sedentary lifestyle can also affect blood circulation as it reduces the amount ofphysical activity that can help to improve blood flow.In conclusion, blood circulation is a vital processthat ensures the proper functioning of our body. It is essential to maintain a healthy lifestyle and avoid factors that can negatively affect blood circulation.中文：血液循环是我们身体中的一个重要过程，它能够将营养物质、氧气和废物产品运输到全身各处。
