Heart The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, as well as assists in the removal of metabolic wastes. The heart is located in the middle compartment of the chest. In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria; and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart.

Complete Heart Block The heart is made up of four chambers. The upper chambers, called the atriums, receive and collect blood. The lower chambers, called the ventricles, pump blood to the body. Working together, the chambers of the heart move life-sustaining blood throughout the body.

Heart Heart Facts. The heart is a strong and muscular organ that is about the size of a fist in adults. It pumps blood throughout the body and is located behind the breastbone between the lungs. Deoxygenated blood flows from the heart to the lungs where it gives up carbon dioxide and is freshly oxygenated.

Heart Anatomy Your heart is located between your lungs in the middle of your chest, behind and slightly to the left of your breastbone (sternum). A double-layered membrane called the pericardium surrounds your heart like a sac.he heart weighs between 7 and 15 ounces (200 to 425 grams) and is a little larger than the size of your fist. By the end of a long life, a person's heart may have beat (expanded and contracted) more than 3.5 billion times.

How does the heart work? The semilunar valves (pulmonary valve and aortic valve) are one-way valves that separate the ventricles from major arteries. The aortic valve separates the left ventricle from the aorta, while the pulmonary valve separates the right ventricle from the pulmonary artery.

The cardiovascular centre is a part of the human brain responsible for the regulation of the rate at which the The right side of your heart receives blood from the body and pumps it to the lungs. The left side of the heart does the exact opposite: It receives blood from the lungs and p…umps it out to the body. Each side has a different function this is why they are divided. This is why the heart is divided into left and right. Because we need both the different things that each side does.

Basic anatomy and function of the heart The heart is a muscular organ that pumps blood to all the tissues in your body through a network of blood vessels. The right side of the heart pumps blood through the lungs where it picks up oxygen. The left side of the heart receives the blood containing oxygen and pumps the blood to the rest of your body. Your heart has four chambers and four valves that regulate blood flow: Left and right atria. Left and right ventricles.

Human Heart: Anatomy, Function & Facts The tricuspid valve and the mitral valve make up the atrioventricular (AV) valves, which connect the atria and the ventricles. The pulmonary semi-lunar valve separates the right ventricle from the pulmonary artery, and the aortic valve separates the left ventricle from the aorta. The heartstrings, or chordae tendinae, anchor the valves to heart muscles. The sinoatrial node produces the electrical pulses that drive heart contractions.

The Heart The heart contains two upper chambers called atria and two lower chambers called ventricles. The left and right sides of the heart are separated by the septum. Valves prevent the backflow of blood and separate the atria from the ventricle and the ventricle from the pulmonary artery or aorta. Key Terms

Atrial Septal Defect (ASD) To understand holes in the heart, it's helpful to know how a healthy heart works. Your child's heart is a muscle about the size of his or her fist. The heart works like a pump and beats 100,000 times a day. The heart has two sides, separated by an inner wall called the septum. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body. The heart has four chambers and four valves and is connected to various blood vessels.

- The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system. The heart has four chambers:

- The septum is solid so that blood cannot flow back and forth between the left and right halves of the heart. Another wall separates the rounded top part of the heart from the cone-shaped bottom part. So there are actually four chambers (spaces) inside the heart. Each top chamber is called an atrium (plural: atria).

The Structure of the Heart It is essential that blood flows in the correct direction through the heart so the structure of the heart includes a series of valves. 1  The Tricuspid valve separates the right atrium from the right ventricle.he Heart is divided into separate right and left sections by the interventricular septum, or septum when the context is clearly that of the heart. Each of these (right and left) sections is also divided into upper and lower compartments known as atria and ventricles, respectively.

- The heart is located in a central tissue mass that divides the ribcage into two cavities between the two lungs. This central tissue consists of the heart, its associated blood vessels, the esophagus, and the trachea. The axis of the heart is tilted so that the apex (tip) of the heart points toward the lower left.

Normal Heart Your heart is divided into two separate pumping systems, the right side and the left side. The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where the blood picks up oxygen and gets rid of carbon dioxide.

- Rating Newest Oldest. Best Answer: The heart is located in the chest between the lungs behind the sternum and above the diaphragm. It is surrounded by the pericardium. Its size is about that of a fist, and its weight is about 250-300 g. Its center is located about 1.5 cm to the left of the midsagittal plane.

Heart The heart is cone-shaped, with its base positioned upwards and tapering down to the apex. An adult heart has a mass of 250–350 grams (9–12 oz). The heart is typically the size of a fist: 12 cm (5 in) in length, 8 cm (3.5 in) wide, and 6 cm (2.5 in) in thickness.

How the Heart Works There is a wall (septum) between the two atria and another wall between the two ventricles. Arteries and veins go into and out of the heart. Arteries carry blood away from the heart and veins carry blood to the heart. The flow of blood through the vessels and chambers of the heart is controlled by valves.

What is Ear Wax and Why Do We Have It? 1 Cleaning your ear with cotton buds (which most of us call Q-tips), napkins, keys, or bobby pins can push the ear wax deeper inside your ear-all the way to the inner ear canal. 2  Hearing aids, ear-bud headphones, and ear plugs can also promote wax buildup in the inner ear, as they stop the wax from falling out on its own.
