The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs..
What is heart Short answer?
Heart: The muscle that pumps blood received from veins into arteries throughout the body. … The heart is composed of specialized cardiac muscle, and it is four-chambered, with a right atrium and ventricle, and an anatomically separate left atrium and ventricle.
Why is the heart so important?
The heart is important because it pumps blood around your body, delivering oxygen and nutrients to your cells and removing waste products. The heart has four chambers: two upper chambers called the right and left atria (singular: atrium) and two lower chambers called the right and left ventricles.

How the heart works step by step?
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
What is the function of heart answer?
It’s the muscle at the centre of your circulation system, pumping blood around your body as your heart beats. This blood sends oxygen and nutrients to all parts of your body, and carries away unwanted carbon dioxide and waste products.
How is the heart made up?
The heart is made of three layers of tissue. Endocardium, the thin inner lining of the heart chambers that also forms the surface of the valves. Myocardium, the thick middle layer of muscle that allows your heart chambers to contract and relax to pump blood to your body. Pericardium, the sac that surrounds your heart.

What are the three main functions of the heart?
The cardiovascular system has three main functions:transport of oxygen, carbon dioxide and nutrients.clotting of open wounds.regulation of body temperature.
Is Heart A organ?
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.
Can a person live without a heart?
A device called the Total Artificial Heart helps some of the sickest heart-failure patients regain function — outside of the hospital — while awaiting a transplant.
How does a healthy heart work?
The left ventricle pumps the oxygen-rich blood into the aorta through the aortic valve and out to the rest of your body. The oxygen-rich blood travels throughout your body. Veins carry the oxygen-poor body back to the right atrium. The right atrium fills with oxygen-poor blood.
What can go wrong with the heart?
Problems with your heart and circulatory system, including heart attack, angina and stroke can occur when your arteries become narrowed. This is caused by a gradual build-up of fatty material (called atheroma) within the blood vessel walls.
Which side is the heart?
