Cardiovascular system has three main functions: Transport of nutrients, oxygen and hormones to cells throughout our body and removal of metabolic wastes such as (carbon dioxide and nitrogenous wastes). Protections of the human body by while blood cells, antibodies and complement proteins that circulate in the blood and defend our body against foreign microbes and toxic. Clotting mechanisms are also present that protect the human body from blood loss after injuries. Regulation of body temperature, fluid pH and water content of
The lymph vessels collect fluid, called lymph from the body tissues and return it to the blood, maintaining the fluid balance within the body. Lymph filters through the lymph nodes, which are packed with white blood cells known as lymphocytes. These are produced in the bone marrow, spleen and thymus, and they help to protect the body against infections. Spleen: This is the largest lymphatic organ. It is located on the left side of the body just above the kidney.
D1 The cardiovascular and respiratory system interlink with each other, this is because they both have a link when it comes to gases exchange. This is because inside the lungs there are air sacs they are called the alveoli there are millions of alveoli, around each alveoli are capillaries which are small blood vessels, as the walls of this is thin carbon dioxide goes into the alveoli from the capillaries and the oxygen goes back into the capillaries which then goes into heart, and the heart pumps blood all around the body. These systems work very closely together, this is to make sure that organ tissues get enough oxygen. Oxygen is needed for cellular function. The air which we breathe in which is kept in the lungs, is the transferred into blood.
Anatomy & Physiology Chapter 19: Vascular * Contrast the structure and function of the various types of blood vessels * Explain how the venous blood is returned to the heart * Explain blood pressure and pulse * Discuss the factors that affect blood pressure * Contrast the clinical significance of systolic, diastolic, and pulse pressure * Discuss the mechanism of capillary exchange * Describe blood flow through systemic and pulmonary circuits. Identify the principal arteries and veins of the systemic, pulmonary, and hepatic portal circulations * Describe unique aspects of fetal circulation * Explain the effects of exercise on the cardiovascular system * Describe significant cardiovascular diseases
As we continue to make our way to the heart, we merge with the right external iliac vein. This is also another name for the femoral vein, and is also considered a deep vein in the lower leg. Its main responsibility is taking deoxygenated blood from the legs back to the heart. It is located right behind the inguinal ligament in the lower abdomen. The inguinal ligament support the area between the abdomen and the thigh (Inguinal Ligament, n.d.).
The blood from these arteries feeds the organs and systems (cells & tissues). Once the blood has given up all its oxygen it makes its way back through the heart, through the veins. Blood from the lower part of the body enters the heart through the inferior vena cava. Blood from the top of the body enters the heart through the superior vena cava. Blood only flows in one direction through the heart; the two values (bicuspid & tricuspid) ensure that this happens.
The cardiovascular system is responsible for transporting nutrients and removing waste from the body as gas. The cardiovascular system consists of the heart and the circulatory system. The heart is the main organ of the body and it helps transport blood and oxygen around the body. The heart produces electrical impulses through a process called cardiac conduction. The impulses produced cause the heart to
Unit 5 P4, M1 & D1 Introduction In this assignment I will be explaining the physiology of two named body systems in relation to energy metabolism. I will also be discussing the role of energy in the body and analysing the interrelationship between the respiratory system and the circularity system and how they perform gaseous exchange. The Cardiovascular System The cardiovascular system has many different functions. The four major functions are to transport gases, nutrients and waste products around the body, to help the body maintain constant body temperature, to protect the body from infection and blood loss and to help the body maintain fluid balance. It has many different components within the cardiovascular system too, the main components include the heart, arteries, veins, capillaries and the blood.
Cardiovascular System: Blood Lab Report assistant Exercise 1: Observing Blood Questions A. What are the components of blood? Components of blood are: Red blood cells White blood cells Plasma and Platelets B. What is the function of red blood cells? The main function of red blood cell is to transport oxygen in blood to all cells of the body.
This means the metabolic system is essential for the body getting energy. Diabetes specifically affects the pancreas, and insulin production. Insulin regulate glucose, or sugar, in the blood. As a result, blood sugar levels are affected. Other than the digestive system, numerous body systems are affected, because blood sugar is essential to maintaining bodily functions.
