Español. Your heart is in the center of your chest, near your lungs. It has four hollow chambers surrounded by muscle and other heart tissue. The chambers are Blood Flow Through the Heart [Made Easy] - Cardiac Circulation Animation. The Heart and Circulatory System - How They Work. Anatomy of the heart made easy along with
Anatomy of the Heart: Structures and Blood Flow [Cardiology
Blood Flow Through the Heart. The human heart is primarily comprised of four chambers. The two upper chambers are called the atria, the remaining two lower chambers are the ventricles. The right and left sides of the heart are separated by a muscle called the “septum.” Both sides work together to efficiently circulate the blood Blood Flow Through the Heart [Made Easy] - Cardiac Circulation Animation.

Heart. Rotate the 3D model to see how the heart's valves control blood flow between heart chambers and blood flow out of the heart. The heart is a hollow, muscular organ that pumps oxygenated blood throughout the body and deoxygenated blood to the lungs Blood flows from the atria into the ventricles through the atrioventricular orifices (right and left)–openings in the atrioventricular septa. These openings are periodically shut and open by the heart valves, depending on the phase of the heart cycle Español. Arteries and veins link your heart to the rest of the circulatory system. Veins bring blood to your heart. Arteries take blood away from your heart. Lesson 1: Circulatory anatomy and blood flow. Meet the heart! Flow through the heart. Two circulations in the body. The heart is a double pump. Parts of the heart. Lub dub. Arteries vs. veins - what's the difference? Arteries, arterioles, venules, and veins. Thermoregulation in the circulatory system. Science > Health and medicine > The cardiovascular system consists of circuits: Pulmonary circuit provides blood flow between the heart and lungs. Systemic circuit allows blood to flow to and from the rest of the body. Coronary circuit provides blood to the heart. The heart valves ensure that blood flows in one direction through the system Illustrations of Blood Flow to the Heart. Location and size of the heart. The heart is located under the rib cage -- 2/3 of it is to the left of your breastbone (sternum) -- and between your lungs and above the diaphragm. The heart is about the size of a closed fist, weighs about ounces, and is somewhat cone-shaped In this Higher Human Biology revision guide, you will learn in detail that cardiac output is a measure of the rate of blood flow through the heart and its associated blood vessels. You can Learning Objectives. By the end of this section, you will be able to: Describe the location and position of the heart within the body cavity. Describe the internal and external
