What are the parts of the circulatory system?
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 are the main cells in the circulatory system?
Red blood cells – to carry oxygen. White blood cells – that make up part of the immune system. Platelets – needed for clotting. Plasma – blood cells, nutrients and wastes float in this liquid.
What are the 4 main parts of the circulatory system?
Circulatory System Parts. The circulatory system consists of the heart, blood, blood vessels, lymph, and lymphatic vessels.
What are the two main components of the circulatory system?
What Are the Parts of the Circulatory System? Two pathways come from the heart: The pulmonary circulation is a short loop from the heart to the lungs and back again. The systemic circulation carries blood from the heart to all the other parts of the body and back again.
Where does the circulatory system start?
The circulatory system begins in your right atrium, the upper right-hand chamber of your heart.
What are the 3 major parts of the circulatory system?
An Introduction to the Cardiovascular System
The cardiovascular system can be thought of as the transport system of the body. This system has three main components: the heart, the blood vessel and the blood itself. The heart is the system’s pump and the blood vessels are like the delivery routes.
What cell is the circulatory system?
The Circulatory System
Blood is formed from stem cells in the bone marrow. The heart pumps blood through its four chambers with the help of valves, which prevent backflow. A conducting system, composed of modified cardiac muscle cells, regulates the nature and frequency of the heartbeat.
Why is it called the circulatory system?
The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in …
What is the other name of circulatory system?
cardiovascular system: The heart and circulatory system (also called the cardiovascular system) make up the network that delivers blood to the body’s tissues.
How many types of circulatory systems are there?

Which is the correct direction of blood flow?
The right and left sides of the heart work together

Is your heart part of the circulatory system?
Topic Overview. The heart is at the center of your circulatory system, which is a network of blood vessels that delivers blood to every part of your body. Blood carries oxygen and other important nutrients that all body organs need to stay healthy and to work properly.
How the circulatory system works with the digestive system?
(1) Inhales (breathes in) Oxygen – good for the body – gives it to the Circulatory System to be transported throughout the body through the blood. (1) Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go.
Why circulatory system is important?
The circulatory system is extremely important in sustaining life. It’s proper functioning is responsible for the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide, waste products, maintenance of optimum pH, and the mobility of the elements, proteins and cells, of the immune system.
