Veins and Arteries in Circulatory System:
Vein and arteries play an inseparable role in circulatory system in which these two essential parts of our body carry the blood flow along with oxygen, essential nutrients, hormones, and other gases to the different body parts.
During this circulatory process cardiovascular part, pulmonary segment, and systemic section work altogether and maintain a healthy blood flow rate all the time.
According to the analysis, an adult person averagely contains 5 to 6 quarters of blood in a healthy flow, which provide a certain amount of plasma, red blood cells, white blood cells, and platelets.
The systemic circulation which incorporates coronary and portal vessels along with veins and arteries considers as the key portion of this circulatory system; hence, it is crucial that the network of veins, as well as arteries transport, oxygenated blood into the blood vessels in an uninterrupted way for all the time.
Though, both parts of veins and arteries of this circulatory system used to carry the blood but, their functions are totally different from each other or rather say, work in a complete contradictory pattern.
As in, arteries carry oxygen-rich blood from the heart through the blood vessels, while veins carry oxygen-poor blood back to our cardiovascular system in return.
To mention more specifically, the key vein vena cava carries oxygen poor-blood back, on the other hand, the main artery Aorta carries oxygenated blood from the left side heart to the other organs as well as tissues through every pump.
When the blood gets back from the right side of the heart with deoxygenated quality, they remove all the wastes from our body tissues as well.
So, if, look closely, the veins and arteries are two pedestals of this circulatory system, while the left ventricle and left atrium of our heart work as the pumping chamber, accordingly the right-sided vessels work for the detoxification along with getting back deoxygenated blood into the heart.
Functions of Arteries:
The main functions of arteries are providing needed supplies to the blood cells and removing the waste products from our system.
The functioning speed depends on the heart pumping rate in a human being and the exact proportion of arteries also varied from human to human.
That’s why the size of a human artery could be a large aorta found in the chest to tiny capillaries detected in the lungs. No matter how big or small artery look, it is always made up with three connective tissue layers with the capacity of the perfect stretch.
If you want to be apparent about the functioning of these arteries, be certain that every type of artery works for four clear and obvious functions in our body and they are as follows-
Functions
- Carrying oxygenated blood from the heart to the other cells and tissues for maintaining the basic cellular functioning
- Dragging out the waste products from the circulatory system like carbon dioxide, urea, etc. through the exhalation process and diffuse into our blood by the normal excreted function of our body
- Transporting essential nutrients like vitamins, minerals, glucose, hormone, crucial chemicals, etc. to the cells from consuming food products
- And providing protecting shield to our body against the foreign substance, which strengthens our immune power perfectly by transporting white blood cells through the main circulation process.
