How does the heart function easy?

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 are the basics of the heart?

  • 4 chambers (2 atria and 2 ventricles) that get blue (deoxygenated) blood from the body. …
  • Blood vessels that include a network of arteries and veins that carry blood throughout the body: …
  • 4 valves to prevent backward flow of blood: …
  • An electrical system that serves as a natural pacemaker.

How does blood flow through the heart for dummies?

Blood flows through your heart and lungs in four steps: The

right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve

. The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve.

How does the heart work automatically?

Your heart has a special electrical system called the

cardiac conduction system

. This system controls the rate and rhythm of the heartbeat. With each heartbeat, an electrical signal travels from the top of the heart to the bottom. As the signal travels, it causes the heart to contract and pump blood.

What are the 3 main functions of the heart?

  • Pumping oxygenated blood to the other body parts.
  • Pumping hormones and other vital substances to different parts of the body.
  • Receiving deoxygenated blood and carrying metabolic waste products from the body and pumping it to the lungs for oxygenation.
  • Maintaining blood pressure.

What are the 13 parts of the heart?

  • Left atrium and auricle. Left atrium. Left auricle.
  • Right atrium and auricle. Right atrium. Right auricle.
  • Interventricular septum and septal papillary muscles. Interventricular septum. …
  • Right ventricle and papillary muscles. Right ventricle. …
  • Left ventricle and papillary muscles. Left ventricle.

What sends blood back to the heart?

Oxygen-poor blood returns from the body to the heart through the

superior vena cava (SVC) and inferior vena cava (IVC)

, the two main veins that bring blood back to the heart.

What carries blood back to the heart?

The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues.

The veins

(blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.

Which artery connects the heart to the lungs?

In the lungs,

the pulmonary arteries

(in blue) carry unoxygenated blood from the heart into the lungs. Throughout the body, the arteries (in red) deliver oxygenated blood and nutrients to all of the body's tissues, and the veins (in blue) return oxygen-poor blood back to the heart.

What keeps the heart beating regularly?

Your heart rhythm is normally controlled by

a natural pacemaker (sinus node) located

in the right atrium. The sinus node produces electrical impulses that normally start each heartbeat. These impulses cause the atria muscles to contract and pump blood into the ventricles.

What exactly does the heart do?

The task of your heart is

to pump enough blood to deliver a continuous supply of oxygen and other nutrients to the brain

and the other vital organs.

What function does the heart perform?

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.

What's the main artery called?

The largest artery is

the aorta

, the main high-pressure pipeline connected to the heart's left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries' smaller branches are called arterioles and capillaries.
