Human Respiratory system and the circulation of blood
Hello everyone! Do you know what is the human's respiratory organ. Yes, it is the lungs, we humans respire using the lungs. The Respiratory Organ will differ for each animal. The circulation of the blood will also be included in the process of Respiration. Today we are going to learn about the human Respiratory system. and the circulation of blood.
What is Respiration?
Respiration is the action of breathing. It is the action of breathing in Oxygen for our cells and tissues and breathing out carbon dioxide.
First we will breath in oxygen by our nose.
The oxygen will go through the air pipe or wind pipe.
From the air pipe the oxygen will go to the lungs. The oxygen will go to the alveoli present in the lungs. Then oxygen will go to the capillaries surrounding alveoli.
These capillaries together will form the pulmonary vein.
From the capillaries the oxygenated blood will reach the left side of the heart by pulmonary vein.
From the heart , the oxygenated blood will reach all the cells of the body.
Now , the deoxygenated blood in our human body reaches the right side of the heart.
The deoxygenated blood will enter into the heart through the superior vena cava and inferior vena cava.
From the heart the de oxygenated blood will go to the lungs through the pulmonary artery
Pulmonary artery divides into small capillaries which surrounds the alveoli.
The alveoli will filter the Carbon dioxide from the capillaries. And let the Carbon Dioxide come out of the body.
This is how we all humans respire and the circulation of the blood.
Thank you!
