Heart Diagram with Labels and Detailed Explanation
The cardiac skeleton also provides an important boundary in the heart electrical conduction system. Figure 16.4.1 16.4. 1: Internal Structures of the Heart This anterior view of the heart shows the four chambers, the major vessels and their early branches, as well as the valves. The presence of the pulmonary trunk and aorta covers the.

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.

o Look at the right-hand diagram. Cut carefully upwards into the left atrium along the line shown in the diagram. p Measure and record the thickness of the walls of the atrium and the ventricle. q Examine the right side of the heart in a similar way. r Look at the areas where an atrium joins a ventricle. Examine the structures there.

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).

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.

The heart is a hollow, muscular organ located in the chest cavity It is protected in the chest cavity by the pericardium, a tough and fibrous sac The human heart has four chambers and is separated into two halves by the septum The heart is divided into four chambers. The two top chambers are atria and the bottom two chambers are ventricles

The heart is a hollow muscular organ that lies in the middle of the chest cavity. It is enclosed in the pericardium, which protects the heart and facilitates its pumping action. The heart is divided into four chambers: The two atria (auricles): these are the upper two chambers. They have thin walls which receive blood from veins.

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.
IGCSE Biology 2017 2.65 Describe the Structure of the Heart and How it Functions
The heart is a muscular organ that pumps blood throughout the body. It is located in the middle cavity of the chest, between the lungs. In most people, the heart is located on the left side of the chest, beneath the breastbone. The heart is composed of smooth muscle. It has four chambers which contract in a specific order, allowing the human.
