The lymphatic system is the bodies’ drainage network that keeps the bodily fluid balanced and also fights off infections to keep he body healthy. The lymphatic system is made up of a variety of lymphatic vessels and organs. (The Spleen and Lymphatic System, Teens Health) The lymphatic system as a whole is similar to the cardiovascular system and has three specific functions. The vessels for one pick up extra fluid and return it to the bloodstream. Secondly, the lacteals receive lipoproteins and then the lymphatic vessels transport these fats also to the bloodstream. Lastly, as stated previously the lymphatic system keeps the body healthy and fights infections. (Lymph Transport and Immunity, McGraw Hill) Lymphatic vessels are a pivotal part in the lymphatic system. Their role is to transport fluid away from tissues. Vessels transport a fluid known as lymph. Lymph is a clear fluid that derives from blood plasma and exits blood vessels found in the capillary beds. Lymph vessels filter the lymph before sending it to the blood vessels located near the heart. The returning of lymph helps maintain low blood pressure and help prevent excess fluid known as edema. (Lymphatic Vessels, Bailey) The smallest lymphatic vessels are called lymph capillaries. These vessels are closed at the ends and have thin walls that enable interstitial fluid to flow into the capillary vessel. Lymphatic capillaries join as lymphatic vessels that merge before entering the thoracic duct or the right lymphatic duct. The thoracic duct is the larger of the two and serves the bodies left side of the body and also the abdomen. Its job is to deliver lymph to the left subclavian vein within the cardiovascular system. The right lymphatic duct, the smaller of the two, ... ... middle of paper ... ...le weakness. There are no cures for myasthenia gravis, multiple sclerosis, diabetes, or systemic lupus erythematosus and no one knows exactly what causes autoimmune disease but most are triggered from a disabled immune system. With no cures around, these diseases must be controlled by drugs but eventually most will become to debilitating, in many cases leading to a shorter life span than others. (Lymph Transport and Immunity, McGraw Hill) Overall, the lymphatic system is crucial in enabling the body to remain healthy and fight off infection. By absorbing fats and trapping antigens, it helps to keep the body healthy and disease-free. Without the lymphatic system, people would not be able to survive and would be full of disease. In order to survive no matter if you a human or a dog, a healthy lymphatic system is necessary to the survival of these advanced species.
The Hematologic System is regarded as the body’s system that regulates the movement of nutrients, molecules (macro and micro molecules), and oxygen to tissues and metabolic waste products and carbon dioxide out of the tissues (Colbert, 2009). The overall role of the hematologic system is to deliver substances needed for cellular metabolism, temperature regulation, defend the body from injury and microbial infections, and maintain the homeostatic balance or acid-base chemistry of the blood and fluid-electrolyte balance. The Hematologic System is principally made up of the blood, blood vessels, and primary organs that manufacture blood cells such as the bone marrow, spleen, lymph nodes, liver, and thymus gland (Ignatavicius & Workman, 2009). Blood is made up of three distinct components: red blood cells, white blood cells, and plasma, and its role is to transport necessary substances for metabolism (nutrients, hormones and oxygen) to cells and to remove metabolic waste products and carbon dioxide, regulation of body temperature and fluid balance, and protect the body from infections. Blood vessels simply aid the transportation of blood throughout the body, simply in and out of the heart. Spleen on its part is the largest lymphatic organ and functions as the blood filtration system and reservoir, site for fetal hematopoiesis, and mounts immune responses that act against invading infections. Bone marrow is another important component of the hematologic system, and its role is to synthesize new blood cells (Red blood cells white blood cells, and platelets) that constitute a healthy blood count while the liver functions by detoxifying the blood (Colbert, 2009).
The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.
The Structure and Functions of the Arteries Arteries are blood vessels that convey blood from the heart to the tissues of the body. The arteries expand and then constrict with each beat of the heart, a rhythmic movement that may be felt as the pulse. Arteries are usually named from the part of the body that they are found, for example; brachial artery found in the arms, metacarpal artery found in the wrist; or from the organ which they supply as the hepatic artery supplies the liver, pulmonary artery brings deoxygenated blood the lungs. The facial artery is the branch of the external carotid artery that passes up over the lower jaw and supplies the superficial portion of the face; the haemorrhoidal arteries are three vessels that supply the lower end of the rectum; the intercostal arteries are the arteries that supply the space between the ribs; the lingual artery is the branch of the external carotid artery that supplies the tongue. The structure of the artery enables it to perform its function more efficiently.
The largest lymphatic organ in the body is the spleen. The spleen stores healthy blood cells and breaks down aging red blood cells. It also helps make lymphocytes and other types of red blood cells. Another function of the spleen is it collects pathogens from the blood and attacks the trapped pathogens. The adenoids are masses of lymph tissue found in the nose and throat. The two ...
The structure and function of our immune systems is a great help for our body to keep all of us healthy. Our immune system has a specific structure that it should maintain. There are also organs that play a major part for the health of our immune system. These organs are called lymphoid organs because of the lymphocytes that inhabit that area. (white blood cells) Bone marrow is also one of the key elements for the immune system, this is where all of our blood cells are being made along with the white blood cells. With the help of the bone marrow, white blood cells are constantly traveling throughout our bodies using the blood cells for help. Another structure that is important for our immune system is lymphoid tissue. Lymphoid tissue acts as a gateway into our bodies that help to prevent incoming germs.
The lymphatic system is made up of organs and tissues, that defends the body against infectious diseases, while also returning tissue fluids to the body’s bloodstream. The lymphatic system prevents the body from disease and infection by producing white blood cells. The lymphatic system helps our immune
Medical history has been filled with an array of diseases and illnesses, ranging from the common cold to deadly killers. Some are easily treatable and others can be terminal, but some of the worst are those that still remain without a cure; one such disease is amyotrophic lateral sclerosis.
The Respiratory System 1. Define respiration. Respiration is the process of converting glucose to energy, which goes to every cell in the body. 2. Describe the organs of external respiration.
Two types of illnesses related to this are chronic illness (lasting/terminal) and acute illness (minor e.g. the flu). Criticism of the mechanistic model is that it is slightly simplistic and may not always apply because the body cannot always be repaired. The second model is the 'Naturalistic Model', which refers to the notion of equilibrium. In order for the body to remain healthy, there must be a balance. Chinese medicine relies greatly on this notion i.e.
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
There are many ways to categorize illness and disease; one of the most common is chronic illness. Many chronic illnesses have been related to altered health maintenance hypertension and cardiovascular diseases are associated with diet and stress, deficient in exercise, tobacco use, and obesity (Craven 2009). Some researchers define the chronic illness as diseases which have long duration and generally slow development (WHO 2013); it usually takes 6 month or longer than 6 month, and often for the person's life. It has a sluggish onset and eras of reduction for vanishing the symptoms and exacerbation for reappear the symptoms. Some of chronic illness can be directly life-threatening. Others remain over time and need intensive management, such as diabetes, so chronic illness affects physical, emotional, logical, occupational, social, or spiritual functioning. Chronic diseases, such as heart disease, stroke, cancer, chronic respiratory diseases and diabetes, all of these diseases are the cause of mortality in the world, representing 63% of all deaths. So a chronic illness can be stressful and may change the way a person l...
All organ system work together; in order to keep and support the conditions that the cells, tissues, and organs need to function properly. Each organ system has an important function in the body. There is one system that is not as well known as other; it is the integumentary system. Most people know the organs of the integumentary system, but they do not know that these organs work together to form this system.
The urinary system does more than you might think. The obvious functions of the urinary system are excretory and urine formation which transports storage urine and release, but it does quite a lot more. Since it is a regulator of how much water is in the blood it can impact blood pressure but it can also stimulate blood cell formation. Vitamin D is made from the interaction of sunlight and your skin but it is activated to perform its hormone function by the kidney cells. Your blood must stay within a very narrow range of pH for critical chemical reactions to occur, and to prevent damage to cells and tissues. The Urinary System is vital in keeping the pH in proper balance. Summarizing the previous we can conclude that the urinary system has 7 functions in total.
The lymphatic system is a link of tissues and organs that help clear the poisonous toxins, waste and further unwanted elements that are inside the human body. The key function of the lymphatic system is to transport lymph which is a watery fluid substance holding infection that are fighting white blood cells, all over the human body.
Our blood is able to connect all our organs together to create one organism and is able to transport the most vital and important molecules through these blood streams. Hence, blood cells are needed for immune system function and metabolic functions.
