Circulatory System

The way it function is in the delivery of oxygen, nutrient molecules, and hormones and the removal of carbon dioxide, ammonia and other metabolic wastes.

The parts of the system

~The heart: It is your job to keep your heart healthy and there are three main things you need to remember in order to keep your heart healthy.

~The blood:The blood is an amazing substance that is constantly flowing through our bodies

~Blood Cells:

Red Blood Cells are responsible for carrying oxygen and carbon dioxide. Red Blood Cells pick up oxygen in the lungs and transport it to all the body cells

White Blood Cells help the body fight off germs. White Blood Cells attack and destroy germs when they enter the body. When you have an infection your body will produce more White Blood Cells to help fight an infection

Platelets are blood cells that help stop bleeding. When we cut ourselves we have broken a blood vessel and the blood leaks out

5 interesting Facts

  • The heart beats around 3 billion times in the averages person's life.
  • About 8 million blood cells die in the human body every second, and the same number are born each second.
  • Within a tiny droplet of blood, there are some 5 million red blood cells.
  • It takes about 20 seconds for a red blood cell to circle the whole body.
  • Red blood cells make approximately 250,000 round trips of the body before returning to the bone marrow, where they were born, to die

How the system helps to maintain homeostasis

~The systems of the body participate in maintaining homeostasis, that is, the relative constancy of the internal environment despite external environmental changes

How Circulatory system works with other system

  1. The circulatory system works closely with other system  in our bodies. It supplies oxygen and nutrients to our bodies by working with the respiratory system. At the same time, circulatory system the helps carry waste and carbon dioxide out of the body.

A problem that can occur with this system and how it affects life (A disease)

~circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, oxygen and other gases, and hormones to and from cells. Without the circulatory system, the body would not be able to fight disease or maintain a stable internal environment
