The circulatory system is a vital system in the human body that is responsible for the delivery of blood, oxygen, nutrients, and hormones to all of the body's cells. It is a complex network of blood vessels, the heart, and the blood that flows through them.
The heart is the central organ of the circulatory system. It is a muscular organ that pumps blood throughout the body. The heart has four chambers: the left and right atria, and the left and right ventricles. The left atrium and left ventricle form the left side of the heart, which is responsible for pumping oxygenated blood to the rest of the body. The right atrium and right ventricle form the right side of the heart, which is responsible for pumping deoxygenated blood to the lungs to be oxygenated.
The blood vessels of the circulatory system can be divided into two main types: arteries and veins. Arteries carry oxygenated blood away from the heart to the rest of the body. They have thick walls to withstand the high pressure of the blood being pumped from the heart. Veins carry deoxygenated blood back to the heart from the rest of the body. They have thinner walls and are more flexible to allow for the blood to flow more easily.
The circulatory system also plays a key role in the immune system. White blood cells, which are a type of immune cell, are carried throughout the body in the blood. They help to protect the body from infections and other foreign substances.
The circulatory system is essential for the proper functioning of the body. Without it, the body's cells would not receive the oxygen and nutrients they need to survive. It is important to maintain a healthy circulatory system by eating a balanced diet, exercising regularly, and not smoking. By taking care of our circulatory system, we can help to ensure that our bodies are able to function at their best.
Inflammatory Process: Circulatory and Lymphatic System Essay Ireland
Many animals live in environments where lungs would be efficient enough for survival. Blood Pressure is the amount of force against the walls of the blood vessels by the circulating blood. . The fish has a two-chambered heart which consists of one atrium and one ventricle. These proteins are released in response to the presence of unwanted organisms like Gram-negative bacteria and cause its blood to clot around the injury and bacteria, protecting the animal from further harm. Permeability of the endothelium is important because oxygen, nutrients and white blood cells need to be transported through the blood vessels to reach other organs. Medical Diagnosis Carcinogenic shock… Echocardiography echo can be used to evaluate your cardiac performance, the function of your heart valves, the thickness and motion of your heart walls, and the size of your heart chambers.
The Circulatory System
Red blood cells are responsible for the transport of oxygen and removal of carbon dioxide. Its structure is rather complicated, as it is made up of a number of liquids and solids mixed with small portions of oxygen and carbon dioxide. The body is a physical structure which sustains a profusion of systems that work coercively to maintain life. But, before learning about inflammation and its causes, let us study the circulatory and lymphatic systems and their working. The endothelium can be found throughout the entire circulatory system. When the blood has picked up its oxygen, it enters some blood vessels known as the cardiac veins. Arterioles are blood vessel that branch off arteries and lead to capillaries.
The Circulatory System Essays
It is in the category of connecting tissue due to it being made up of non-living fluid in which a living cell is deferred. In one pump we find the right atrium and ventricle they deal with deoxygenated blood. . The right atrium receives blood oxygen-depleted blood from the body through the two largest veins, superior and inferior vena cava. The second point to remember is that when blood circulates in the body, then it supplies oxygen, digested food and other chemicals like hormones to all the cells of the body. Blood is composed of three main elements; plasma, formed elements and platelets. The fluid is known as Lymph and it also contains White Blood Cells.
Functions of the Circulatory System Essay
Observe and state the changes in trends and use the theory discussed in class to justify these changes. We have just studied that the heart is a kind of pump which pumps blood around our body continuously, without stopping. Arteries, veins and capillaries are called blood vessels. The formed elements consist of red and white blood cells. Here, the blood is enriched with oxygen in the alveoli and then, it is pumped back into the heart.
