What is the Circulatory System?
The main function of the circulatory system is to provide oxygen throughout your body. Another part of the circulatory system is to remove waste from cells and organs so your body can dispose of it. Your heart pumps blood to the body through a network of arteries and veins (blood vessels). Your circulatory system can also be defined as your cardiovascular system. Cardio means heart, and vascular refers to blood vessels. This blood circulation keeps organs, muscles and tissues healthy and working to keep you alive
This blood circulation keeps organs, muscles and tissues healthy and working to keep you alive.
The circulatory system also helps your body get rid of waste products. This waste includes:
Carbon dioxide from respiration (breathing).
Other chemicals from your organs.
Waste from things you eat and drink.
What are the parts of the Circulatory System?
he parts of your circulatory system are your:
Heart, a muscular organ that pumps blood throughout your body.
Blood vessels, which include your arteries, veins and capillaries. Blood vessels carry blood away from and towards the heart.
Blood, made up of red and white blood cells, plasma and platelets.
How does the circulatory system work?
Your circulatory system functions with the help of blood vessels that include arteries, veins and capillaries. These blood vessels work with your heart and lungs to continuously circulate blood through your body, This is how:
The heart’s bottom right pumping chamber sends blood that’s low in oxygen to the lungs. Blood travels through the pulmonary trunk (the main pulmonary artery).
Blood cells pick up oxygen in the lungs.
Pulmonary veins carry the oxygenated blood from the lungs to the heart’s left atrium (upper heart chamber).
The left atrium sends the oxygenated blood into the left ventricle (lower chamber). This muscular part of the heart pumps blood out to the body through the arteries.
As it moves through your body and organs, blood collects and drops off nutrients and waste products.
The veins carry deoxygenated blood and carbon dioxide back to the heart, which sends the blood to the lungs.
Your lungs get rid of the carbon dioxide when you exhale.
What is red blood and blue blood?
All blood is red. Hemoglobin, an iron-rich protein in red blood cells, mixes with oxygen to give blood its red color. Blood that’s rich in oxygen is known as red blood.
Your veins carry oxygen-poor blood. This is sometimes called blue blood because your veins can look blue underneath the skin. The blood is actually red, but the low oxygen levels give veins a bluish hue.
What are the circulatory system circuits
Your circulatory system has three circuits. Blood circulates through your heart and through these circuits in a continuous pattern:
The pulmonary circuit: This circuit carries blood without oxygen from the heart to the lungs. The pulmonary veins return oxygenated blood to the heart.
The systemic circuit: In this circuit, blood with oxygen, nutrients and hormones travels from the heart to the rest of the body. In the veins, the blood picks up waste products as the body uses up the oxygen, nutrients and hormones.
The coronary circuit: Coronary refers to your heart’s arteries. This circuit provides the heart muscle with oxygenated blood. The coronary circuit then returns oxygen-poor blood to the heart’s right upper chamber (atrium) to send to the lungs for oxygen.
What are the types of blood vessels?
Arteries: Thin, muscular tubes which transport the oxygenated blood away from the heart and to every part of the body
Vein: A thin-walled blood vessel with values that leads blood towards the heart. When the vein is started, it is small and as it approaches the heart, it gets larger
Capillaries: These blood vessels connect very small arteries and veins. Capillaries have thin walls that allow oxygen, carbon dioxide, nutrients and waste products to pass into and out of cells.
