Systemic circulation . Coronary circulation
What is class 3 circulatory system?
The circulatory system is made up of blood vessels that carry blood away from and towards the heart . Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
What are the three 3 main parts of the circulatory system?
The essential components of the human cardiovascular system are the heart, blood and blood vessels . It includes the pulmonary circulation, a “loop” through the lungs where blood is oxygenated; and the systemic circulation, a “loop” through the rest of the body to provide oxygenated blood.
What are the 4 main parts of the circulatory system?
The circulatory system is composed of the heart, arteries, capillaries, and veins . This remarkable system transports oxygenated blood from the lungs and heart throughout the body via the arteries.
What are the types of circulatory systems?
There Are Two Types of Circulation: Pulmonary Circulation and Systemic Circulation . Pulmonary circulation moves blood between the heart and the lungs.
What is the largest artery found in the body?
The largest artery is the aorta , the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
What are the thinnest veins called?
Venules are the smallest, thinnest veins. They receive blood from the capillaries and deliver that blood into larger veins. The walls of the veins have the same three layers as the arteries: the tunica intima, the tunica media, and the tunica adventitia.
Why is it called the circulatory system?
As the name implies, blood contained in the circulatory system is pumped by the heart around a closed circle or circuit of vessels as it passes again and again through the various “circulations” of the body .
What are the two main routes of double circulation?
- Pulmonary Artery: It takes deoxygenated blood to the lungs.
- Aorta: It carries oxygenated blood to the body tissues.
- Pulmonary Vein: It carries oxygenated blood.
- Vena Cava: It takes deoxygenated blood.
What is circulatory system with diagram?
The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells.
What does the circulatory system Transport?
The circulatory system delivers oxygen and nutrients to cells and takes away wastes . The heart pumps oxygenated and deoxygenated blood on different sides. The types of blood vessels include arteries, capillaries and veins.
How does blood circulate in our body?
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.
What the two major components of blood are?
- Erythrocytes, also known as red blood cells (RBCs)
- Leukocytes, also known as white blood cells (WBCs)
- Platelets.
What are the 2 circulatory systems?
Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation (the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again.
What are open and closed circulatory systems?
| Open Circulatory System Closed Circulatory System | The hemolymph directly bathes the organs and tissues. The blood circulates within closed vessels. |

What animals have a circulatory system?
Most mammals , including humans, have this type of circulatory system. These circulatory systems are called ‘double’ circulatory systems because they are made up of two circuits, referred to as the pulmonary and systemic circulatory systems. Humans, birds, and mammals have a four-chambered heart.
