Hello friends, what’s going on? Today we are discuss about the Circulatory system of the heart.
You know that, Heart is pump a machine, usually beating about 60 to 100 times per minute. With each heartbeat, the heart sends blood to overall body, which carries the oxygen, the blood returns to the heart. The heart pass the blood to the lungs to pick up more oxygen. This cycle repeats again and again.
What Does the Circulatory System :
The circulatory system is made up of blood vessels that pass the blood to the body and from body to the hearts. Arteries pass the blood away from the heart and venis pass blood to the heart from the body.
The circulatory system oxygen nutrients, and harmones to cells, and removes waste products, like carbon dioxide. The roadways travels in only one direction, to keep these things going where they should.
What Are the Parts of the Heart?
The heart is divide into four chembers – two on top and two on bottom.
The right ventricle and the left ventricle are two bottom chembers,. These ventricles pumps the blood out of the heart. The wall situated between the ventricles are called interventricular septum.
The right atrium and the left atrium are the top two chembers of the heart, which recieves the blood entering the heart. The wall which is situated between two atria called interatrial system.
The atria are separated because of atrioventricular valves.
The tricuspid valve divides the right atrium from to the right ventricle.
The mitral valve divides the left atrium from to the left ventricle.
The two valves also blood the ventricles from the large blood vessels that carry blood leaving the heart:
The pulmonic valve is situated between the right ventricle and the pulmonary artery, which carries blood from body to the lungs.
The aortic valve is situated between the left ventricle and the aorta, which carries blood from heart to the body.
Parts of the Circulatory System :
It is the two parts of the circulatory system.
First is pulmonary circulation which is a short loop from the heart to the lungs and back again.
And the second is systemic circulation carries blood from the heart to all the parts of the body and back again.
The Pulmonary Circulation :
The pulmonary artery is a big artery system which is comes from the heart. It divides into main two branches, and carries blood from heart to the lungs. In lungs, the blood picks up oxygen and drops off carbon dioxide. The pulmonary system returns the blood to the heart venis.
In systemic Circulation:
In circulatory system of the next, blood that comes from the heart which carries up to lots of oxygen from the lungs. So it is easily go out to the body.The aorta is a big artery system that leaves the heart carrying this oxygenated blood. In systemic circulation. Branches of aorta send blood to the muscles, as well as all the body parts. It is like tree, the branches get from the aorta.
