Major functions of the circulatory system:
- delivers oxygen to the cells and removing carbon dioxide from them
- carries digested food substances to the cells of the body
- disposes of waste products and poisons that would harm the body if they accumulated
- helps protect the body from disease
- the circulatory system provides a mode of transport for hormones

Components of blood:
Red blood cells - Mostly Hemoglobin which basically just carries oxygen
White blood cells - defends the body against infection and disease by ingesting foreign materials and cellular debris
Platelets - tiny blood cells that help your body form clots to stop bleeding
Plasma - proteins and antibodies in plasma are also used to create therapies for rare chronic conditions, such as autoimmune disorders and hemophilia.

How blood travels?
As the heart beats, it pumps blood through a system of blood vessels called the blood circulatory system. The vessels are elastic tubes that carry blood to every part of the body.
The oxygenated blood enters from either Superior or Inferior vena cava's, where it collects in the right atrium. From there it is ejected out if the tricuspid valve into the right ventricle and out the pulmonary arteries. The non- oxygenated blood enters from either pulmonary veins and fill the left atrium which from there is pushed into the left ventricle and finally out the aorta.

How blood clots close wounds?
When you get a cut, you start bleeding but after a while you stop because of the blood cells forming a clot which is mostly platelets.

How it works with other systems
Nervous System: The nervous system is made up of the brain, spinal cord and nerves. The brain sends messages to the heart telling it to beat. The heart beat pumps blood throughout the body so that nutrients and oxygen can be brought to cells and waste can be removed
Muscular System: The heart is a muscle. The expanding and contracting of this muscle is what pumps blood throughout the body
Fun 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
- Red blood cells may live for about 4 months circulating throughout the body, feeding the 60 trillion other body cells

Diseases
Arrhythmia: There are 3 different types but overall arrhythmia means a abnormality in the rhythm of your heartbeat.
Arteriosclerosis: hardening of the arteries.
