Human Heart Diagram and Anatomy of the Heart StudyPK

The human circulatory system consists of several circuits: The pulmonary circuit provides blood flow between the heart and lungs. The systemic circuit allows blood to flow to and from the rest of the body. The coronary circuit strictly provides blood to the heart (not pictured in the figure below).

In animals with lungs —amphibians, reptiles, birds, and mammals—the heart shows various stages of evolution from a single to a double pump that circulates blood (1) to the lungs and (2) to the body as a whole. In humans and other mammals and in birds, the heart is a four-chambered double pump that is the centre of the circulatory system.

The heart is labelled as if it was in the chest so what is your left on a diagram is actually the right-hand side (and vice versa) The right side of the heart receives deoxygenated blood from the body and pumps it to the lungs where oxygen diffuses in from the alveoli and carbon dioxide diffuses out


External Structures Of The Human Heart

The heart is the control for the circulatory system. It is a muscle that pumps blood around the body. The heart consists of two muscular pumps that lay next to each other. The right side pumps deoxygenated blood to the lungs, whereas the left side pumps oxygenated blood to the whole body. There are four chambers in total.

The heart has four chambers. Blood is pumped between the following four chambers: The Circulatory System - Heart: Structure and Function The right and left sides of the heart are divided by a wall called the septum. This ensures that deoxygenated and oxygenated blood don't mix.

The heart is made of three layers of tissue. Endocardium is the thin inner lining of the heart chambers and also forms the surface of the valves.; Myocardium is the thick middle layer of muscle that allows your heart chambers to contract and relax to pump blood to your body.; Pericardium is the sac that surrounds your heart. Made of thin layers of tissue, it holds the heart in place and.

Heart Diagram with Labels and Detailed Explanation

The heart is the organ that helps supply blood and oxygen to all parts of the body. It is divided by a partition (or septum) into two halves. The halves are, in turn, divided into four chambers. The heart is situated within the chest cavity and surrounded by a fluid-filled sac called the pericardium. This amazing muscle produces electrical.
