Blood […] The cardiovascular system moves blood throughout the body, and the lymphatic system moves lymph, which is a clear fluid thats similar to the plasma in blood. The volume of blood in the body also affects blood pressure. Edit. Venules are similar to arterioles as they are small vessels that connect capillaries, but unlike arterioles, venules connect to veins instead of arteries. The circulatory system, also known as the cardiovascular system, consists of the organs and fluids that transport materials like oxygen and nutrients throughout the body. Blood Vessels Arteries. This key circulatory system structure is comprised of four chambers. Platelets do not contain a nucleus and only survive in the body for up to a week before macrophages capture and digest them. Precapillary sphincters are bands of smooth muscle found at the arteriole ends of capillaries. Our mission is to provide objective, science-based advice to help you make more informed choices. 36. The heart has its own set of blood vessels that provide the myocardium with the oxygen and nutrients necessary to pump blood throughout the body. The heart wall has three layers. As a liquid connective tissue, it transports many substances through the body and helps to maintain homeostasis of nutrients, wastes, and gases. As the heart beats, blood is propelled into large arteries leaving the heart. Arterioles, like arteries, are able to use smooth muscle to control their aperture and regulate blood flow and blood pressure. So, these are the two key parts: the heart, which pumps blood, and the blood vessels, which carry blood to the body and return it back to the heart again. There are two major classes of white blood cells: granular leukocytes and agranular leukocytes. The heart is suspended in its own membranous sac, the pericardium. 10,145 views.

In fact, many are so tiny only one blood cell can move through them at a time. The liver removes toxins, stores sugars, and processes the products of digestion before they reach the other body tissues. Basically, the heart is a pump ensuring the continuous circulation of blood in the body. Circulatory System. Venules eventually join to form veins, which deliver the blood back to your heart to pick up oxygen. They face much lower blood pressures than arteries due to their greater number, decreased blood volume, and distance from the direct pressure of 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. 72% average accuracy. Blood vessels can also affect blood pressure. This lack of pressure allows the walls of veins to be much thinner, less elastic, and less muscular than the walls of arteries. Monocytes develop into cells called macrophages that engulf and ingest pathogens and the dead cells from wounds or infections. The Human Anatomy and Physiology course is designed to introduce students pursuing careers in the allied health field to the anatomy and physiology of the human body.

Rh-negative father and Rh-positive mother. At the Heart of It All: Anatomy and Function of the Heart. To facilitate the movement of blood, some veins contain many one-way valves that prevent blood from flowing away from the heart. Learn cardiovascular system anatomy with free interactive flashcards. Arteries are blood vessels that carry blood away from the heart. The heart is a four-chambered “double pump,” where each side (left and right) operates as a separate pump. The heart is located in the middle of chest. The cardiovascular system can be thought of as the transport system of the body. The cardiovascular system is one of the first body systems to appear within the embryo.It is active by the beginning of the fourth week – when the placenta is unable to meet the requirements of the growing embryo. Red blood cells, also known as erythrocytes, are by far the most common type of blood cell and make up about 45% of blood volume. 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. (adsbygoogle = window.adsbygoogle || []).push({}); The cardiovascular system has three major functions: transportation of materials, protection from pathogens, and regulation of the body’s homeostasis. Platelets form in the red bone marrow from large megakaryocyte cells that periodically rupture and release thousands of pieces of membrane that become the platelets. To withstand this pressure, the walls of the arteries are thicker, more elastic, and more muscular than those of other vessels.
