How blood flows through the body-The Circulatory System

In this video, you will learn about the Circulatory SystemThe circulatory system, is the transportation system of the body and is responsible for the flow of blood in the body. The major structures that make this possible are the heart, blood vessels, and blood.
The heart pumps blood in order to move nutrients oxygen, carbon dioxide disease-fighting white blood cells, and hormones to and from the cells in the body
The circulatory system has two main types of circulation.

The pulmonary
The Systemic
Pulmonary circulation travels from heart to the lung where your blood picks up oxygen and back to the heart
Systemic circulation is from the heart to the body

Your heart has four chambers that is used to pump blood throughout your body.

Two Atria - which are the upper chambers.
Two ventricles - these are the lower chambers
The left and right side of the heart is divided by the septum

Blood Vessels carry blood throughout the body.
Arteries carry blood away from the heart and veins carry blood towards the heart

Capillaries, which are the smallest blood vessels in the body create a network of vessels connecting veins and arteries.
In summary, the heart pumps blood to the body through the arteries and returns blood to the Body through the veins

You have around 1.5 gallons of blood in your body
It is composed of several different types of cells.
The first type of blood cell is the red blood cell. Red blood cells help carry oxygen

The second type of blood cell is known as the white blood cell and helps fight pathogens

The third type of cell is the platelet and create blood clots.
These blood cells are found in a liquid called plasma which consists of water along with electrolytes and some proteins and hormones

In summary, The job of the circulatory system is to circulate blood to and from cells in the body in order to transport nutrients and oxygen and remove carbon dioxide and waste.
