Types of Circulatory System

Open Circulatory System :

In the open circulatory system, blood moves from lacunae, large open gaps, and by sinuses among the tissues. Blood comprises extremely low pressure in this system. They are typically found in higher invertebrates likely insects, prawns, etc. Blood is in intimate contact with the tissues. The exchange of nutrients and gases occurs between the tissue and the blood. Since blood circulates in a free environment, it cannot be prevented. Plasma contains dissolved respiratory pigment from the blood that is passing through this system. There are no red blood cells.

Closed Circulatory System :

A closed circulatory system is more efficient because the volume of blood can be controlled by the contraction and relaxation of the smooth muscles of the blood vessels. The flow of blood in this system is very fast. In a closed circulatory system, blood flows through a closed system of chambers of the heart and blood vessels. Nutrients and gases move from the capillary wall into the tissue fluid.

The circulatory system is a network of organs that permit the circulation of blood. The circulatory system’s other name is the Cardiovascular system or the vascular system. The primary function of the circulatory system is to transport blood to each part of the body. It is necessary because it carries nutrients, oxygen, carbon dioxide, hormones, and blood cells that are necessary for the hydration and growth of each organ’s cell population.

The Blood circulatory systems are many of the most important processes of the body because they deliver required amounts of oxygen in every portion of the body. The arteries transport the oxygenated blood from the heart to the body parts. Oxygen is provided to the body through diffusion and the blood becomes deoxygenated. This deoxygenated blood is carried return to the heart for oxygenation. This process known as blood circulation occurs continuously in all vertebrates.
 

Biology is part of many competitive exams SSC CGL, UPSC, SSC CPO, and Railways. We have written depth notes on the circulatory System To help you understand the Human Circulatory System in a much better way. To know more about Circulatory System which is mentioned below.
