White blood cells, also known as leukocytes, make up a very small percentage of the total number of cells in the bloodstream, but have important functions in the body’s immune system. Blood from the liver then returns to the heart through the inferior vena cava. The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis. The trials conducted at THI are designed to test the safety and effectiveness of innovative new treatments and medications for patients. Anatomy and Physiology of the Cardiovascular System Blood is made up of red blood cells, white blood cells, platelets, and liquid plasma. Blood is carried from your heart to the rest of your body through a complex network of arteries, arterioles, and capillaries. The top of the heart, known as the heart’s base, connects to the great blood vessels of the body: the aorta, vena cava, pulmonary trunk, and pulmonary veins. At the center of it all is the heart. Once the capillaries deliver oxygen and nutrients and pick up carbon dioxide and other waste, they move the blood back through wider vessels called venules. The circulatory system is also called the cardiovascular system, where “cardi” refers to the heart, and “vascular” refers to the blood vessels.

The cardiovascular system includes the heart and blood vessels and performs the function of pumping and carrying blood to the rest of the body. It is the pulmonary artery that brings oxygen-poor blood into your lungs and the pulmonary vein that brings oxygen-rich blood back to your heart. The unique shape of erythrocytes gives these cells a high surface area to volume ratio and allows them to fold to fit into thin capillaries. Each heartbeat results in the simultaneous pumping of both sides of the heart, making the heart a very efficient pump. The heart is the organ that supplies blood and oxygen to all parts of the body. Gravity. In response to the evolving pandemic, emerging topics related to COVID-19 are featured in the special Cardiology in the Time of COVID-19 episodes. To facilitate the movement of blood, some veins contain many one-way valves that prevent blood from flowing away from the heart. Also, explore how DNA health testing can allow you to begin important conversations with your doctor about genetic risks for disorders involving clotting, hemophilia, hemochromatosis (a common hereditary disorder causing iron to accumulate in the heart) and glucose-6-phosphate dehydrogenase (which affects about 1 in 10 African American men). 10,145 views. Test. Many different substances can be found dissolved in the plasma, including glucose, oxygen, carbon dioxide, electrolytes, nutrients, and cellular waste products. In pulmonary circulation, though, the roles are switched. So we have our lungs here. Finish Editing. When the muscle relaxes, the valve traps the blood until another contraction pushes the blood closer to the heart. Blood contains nutrients from the foods you eat and oxygen from the air you breathe. All Rights Reserved. The sympathetic (fight or flight) division of the autonomic nervous system causes vasoconstriction, which leads to increases in blood pressure and decreases in blood flow in the constricted region. To withstand this pressure, the walls of the arteries are thicker, more elastic, and more muscular than those of other vessels. Veins are the large return vessels of the body and act as the blood return counterparts of arteries. Anatomy and Chemistry Basics Quiz: What is Anatomy and Physiology?

The Cardiovascular System is made up of two fundamental parts: The Heart; The Blood Vessels; The heart acts as a pump by pushing out blood; The blood vessels receive this blood, transport it around the body, and eventually bring it back to the heart. The left side of the heart receives oxygenated blood from the lungs and pumps it through the systemic arteries to the tissues of the body. A higher volume of blood in the body raises blood pressure by increasing the amount of blood pumped by each heartbeat. The left and right coronary arteries branch off from the aorta and provide blood to the left and right sides of the heart. The heart is the key organ of the cardiovascular system – the body’s transport system for blood. Immature erythrocytes have a nucleus that is ejected from the cell when it reaches maturity to provide it with its unique shape and flexibility. The left atrium and left ventricle of the heart are the pumping chambers for the systemic circulation loop. Platelets next release chemical clotting factors and begin to produce the protein fibrin to act as structure for the blood clot. o It is composed of the heart and blood vessels. And what we learned in the last few videos is that we have our little alveoli and our lungs. The heart is pyramidal in shape will its apex projecting forwards and downwards to the left side, while its base faces in the opposite, posterior direction.
