Question

How does blood relate to the respiratory system?

Answer 1

Blood is a blend of plasma and cells that flow through the whole body. Blood is a body fluid that provides essential substances such as nutrients and oxygen to the cells of humans and other animals. Blood carries products of metabolic waste away from the same cells.

Complete answer:
To circulate blood and oxygen throughout the body, the circulatory and respiratory systems work together. By means of the trachea, bronchi, and bronchioles, air flows in and out of the lungs. Blood flows through the pulmonary arteries and veins which is binded to the heart in and out of the lungs for the process of oxygenation. The main role of the respiratory system is to inhale the oxygen and exhale the carbon dioxide. The inhaled oxygen is taken up by the RBC of the blood for the process of oxygenation. The deoxygenated blood is sent to the lungs via pulmonary arteries for oxygenation where the carbon dioxide is removed. It enters the lungs once blood passes through the pulmonary valve. Blood flows to the pulmonary arteries from the pulmonic valve and finally to tiny capillary vessels in the lungs. purified blood rich with oxygen is sent back to the heart via pulmonary veins. This type of circulation of blood which involves the respiratory system of the body especially the lungs is known as pulmonary circulation.
Deoxygenated blood is transported by the pulmonary arteries from the heart to the lungs, and oxygenated blood is carried back by the pulmonary veins to the heart to be distributed to the body. Respiratory system and circulatory system work simultaneously and a defect in one of the systems affects the other system.

Note:
All cells in the body need oxygen and nutrients, and need their wastes removed. These are the circulatory system's main roles. In order to service the cells of the body, the heart, blood and blood vessels work together.
