The heart beats around 100,000 times a day, pumping approximately 8 pints of blood throughout the body 24/7.This delivers oxygen- and nutrient-rich blood to tissues and organs and carries away waste.

The heart pumps around 6,000-7,500 litres of blood in a day throughout the body. The heart is situated at the centre of the chest and points slightly towards the left. On average, the heart beats about 100,000 times a day, i.e., around 3 billion beats in a lifetime. The average male heart weighs around 280 to 340 grams (10 to 12 ounces).

heart, organ that serves as a pump to circulate the blood.It may be a straight tube, as in spiders and annelid worms, or a somewhat more elaborate structure with one or more receiving chambers (atria) and a main pumping chamber (ventricle), as in mollusks. In fishes the heart is a folded tube, with three or four enlarged areas that correspond to the chambers in the mammalian heart.

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 ...

Your heart's main function is to move blood throughout your body. Blood brings oxygen and nutrients to your cells. It also takes away carbon dioxide and other waste so other organs can dispose of them. Your heart also: Controls the rhythm and speed of your heart rate. Maintains your blood pressure.

CPR. The position of the heart in the torso between the vertebrae and sternum (see Figure 19.2 for the position of the heart within the thorax) allows for individuals to apply an emergency technique known as cardiopulmonary resuscitation (CPR) if the heart of a patient should stop. By applying pressure with the flat portion of one hand on the sternum in the area between the line at T4 and T9 ...

Cardiology is the study of the heart, and cardiologists are the physicians who deal primarily with the heart. Figure 17.1.1 17.1. 1: Human Heart.

human cardiovascular system, organ system that conveys blood through vessels to and from all parts of the body, carrying nutrients and oxygen to tissues and removing carbon dioxide and other wastes. It is a closed tubular system in which the blood is propelled by a muscular heart. Two circuits, the pulmonary and the systemic, consist of ...

There are one atrium and one ventricle on each side of the heart. The atria receive blood and the ventricles pump blood. 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.

Learning Objectives. After studying this chapter, you will be able to: Identify and describe the interior and exterior parts of the human heart. Describe the path of blood through the cardiac circuits. Describe the size, shape, and location of the heart. Compare cardiac muscle to skeletal and smooth muscle. Explain the cardiac conduction system.

2.The upper part of the heart is made up of two chambers, called the right and left atria, which receive the blood entering the heart. 3.The bottom part of the heart is divided into two chambers, called the right and left ventricles, which pump blood out of the heart. 4.Pulmonary circulation is a short loop from the heart to the lungs and back ...

Region of the heart that pumps oxygenated blood to the body. pulmonary artery. Carries deoxygenated blood to the lungs. right ventricle

The human heart is the organ that pumps blood throughout the body via the vessels of the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes. Pumping the blood through the arteries, capillaries, and veins is the major function of the heart. It maintains proper circulation of blood.
