The Human Circulatory System Shalom Education A double circulatory system strictly separates oxygenated and deoxygenated blood. this means that oxygen is picked up from the lungs, and at the same time, blood is delivered to the body’s cells. so, the cells get a reliable supply of oxygen. blood must travel through small capillaries in the lungs, which causes it to lose a lot of pressure. © shalom education 2024 gcse human circulatory system | activity worksheet 1. match each statement with the corresponding letter in the diagram below.

The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. [1][2] it includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from greek kardia meaning heart, and from latin vascula. The human circulatory system possesses a body wide network of blood vessels. these comprise arteries, veins, and capillaries. the primary function of blood vessels is to transport oxygenated blood and nutrients to all parts of the body. it is also tasked with collecting metabolic wastes to be expelled from the body. This gcse worksheet focuses on the circulatory system, specifically examining the structure and function of veins and heart valves. it presents cross sectional images of veins for students to analyse for circulatory efficiency, asks about the unidirectional flow of blood, and explores the consequences of defective heart valves, including potential medical interventions.
