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 5 major parts of the circulatory system?

- The heart. The heart pumps blood around the body. …
- The right side of the heart. …
- The left side of the heart. …
- Blood vessels. …
- Arteries. …
- Capillaries. …
- Veins.
What are the 3 types of circulatory systems?
- Systemic circulation.
- Coronary circulation.
- Pulmonary circulation.
What are the 7 steps of the circulatory system?
Blood flows through the heart in the following order: 1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) …
What are the function of 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.
How circulatory system works step by step?
The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.
What are the 4 chambers of the heart?
There are four chambers: the left atrium and right atrium (upper chambers), and the left ventricle and right ventricle (lower chambers). The right side of your heart collects blood on its return from the rest of our body. The blood entering the right side of your heart is low in oxygen.
What are the 2 types of circulatory system?
There Are Two Types of Circulation: Pulmonary Circulation and Systemic Circulation. Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart.
What are the 3 basic structures of the cardiovascular system?
- Blood. …
- Blood Vessels. …
- Heart.
How many circulatory system do we have in our body?
There isn’t only one blood circulatory system in the human body, but two, which are connected: The systemic circulation provides organs, tissues and cells with blood so that they get oxygen and other vital substances. The pulmonary circulation is where the fresh oxygen we breathe in enters the blood.
What are the 12 steps of blood flow through the heart?
- Superior Inferior. Vena Cava.
- Right Atrium.
- has 3 flaps. Tricuspid Valve.
- Right Ventricle.
- Pulmonary Valve.
- Pulmonary Artery.
- Pulmonary Vein.
- Left Atrium.
What are the 16 steps of blood flow through the heart?
- #1. inferior vena cava.
- #2. superior vena cava.
- #3. right atrium deoxygenated.
- #4. tricuspid valve.
- #5. right ventricle.
- #6. pulmonary semilunar valve.
- #7. pulmonary artery.
- #8. lungs to get oxygen.
What is the main function of the blood in circulatory system answer?
Blood Provides the Body’s Cells with Oxygen and Removes Carbon Dioxide. Blood absorbs oxygen from air in the lungs. It transports the oxygen to cells throughout the body, and it removes waste carbon dioxide from the cells.
How can you take care of your circulatory system?
- Maintain a healthy weight.
- Don’t smoke.
- Exercise a minimum of 30 minutes a day, most days of the week.
- Maintain a healthy, low-fat, low-cholesterol diet with more fruits, vegetables, and whole grains.
- Avoid trans fats and saturated fats, which are often found in processed foods and fast food.
What is the most important part of the circulatory system?
The heart is the most important part of the circulatory system because without it blood would not be pumped throughout the body. The blood vessels are the most important part as they carry the blood with nutrients and oxygen to the cells.
How many veins are in the heart?
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
What is Cuspid valve?
Valves of the Heart
The heart has two types of valves that keep the blood flowing in the correct direction. The valves between the atria and ventricles are called atrioventricular valves (also called cuspid valves), while those at the bases of the large vessels leaving the ventricles are called semilunar valves.
What is the aorta?
The aorta is the main artery that carries blood away from your heart to the rest of your body. The blood leaves the heart through the aortic valve. Then it travels through the aorta, making a cane-shaped curve that allows other major arteries to deliver oxygen-rich blood to the brain, muscles and other cells.
What is open circulatory system?
Open circulatory systems are systems where blood, rather than being sealed tight in arteries and veins, suffuses the body and may be directly open to the environment at places such as the digestive tract. Open circulatory systems use hemolymph instead of blood.
What is the largest artery in the body?
Aorta Anatomy
The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
What is open and closed circulatory system?
1: Closed and open circulatory systems: (a) In closed circulatory systems, the heart pumps blood through vessels that are separate from the interstitial fluid of the body. … In an open circulatory system, the blood is not enclosed in the blood vessels, but is pumped into a cavity called a hemocoel.
What can you do to improve circulation?
- Increase cardiovascular exercise. …
- If you smoke, quit. …
- Drink black or green tea. …
- If you are anemic, take iron supplements or eat iron-rich food. …
- Dry brush your body. …
- Decrease stress. …
- Include more omega-3 fatty acids in your diet. …
- Wear compression socks and elevate your legs.
What is the smallest blood vessels in the body?
Capillaries, the smallest blood vessels, connect arteries and veins.
How long is the circulatory system?
This vast system of blood vessels – arteries, veins, and capillaries – is over 60,000 miles long. That’s long enough to go around the world more than twice! Blood flows continuously through your body’s blood vessels.
Which body part belongs to the circulatory system?
The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries.
How many valves does the heart have?
Your heart has four valves that keep blood flowing in the correct direction. In some cases, one or more of the valves don’t open or close properly. This can cause the blood flow through your heart to your body to be disrupted.
Which is more important systemic circulation or pulmonary circulation?
Systemic circulation as a whole is a higher pressure system than pulmonary circulation simply because systemic circulation must force greater volumes of blood farther through the body compared to pulmonary circulation.
What is the correct order of blood flow starting from the heart?
The blood first enters the right atrium. The blood then flows through the tricuspid valve into the right ventricle. When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery. The pulmonary artery carries blood to the lungs where it “picks up” oxygen.
Which of the following is NOT a circulatory system?
The correct answer is Villi.
How does the blood get oxygen?
Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.
What are 6 critical blood functions?
- transporting oxygen and nutrients to the lungs and tissues.
- forming blood clots to prevent excess blood loss.
- carrying cells and antibodies that fight infection.
- bringing waste products to the kidneys and liver, which filter and clean the blood.
- regulating body temperature.
What are 5 critical blood functions?
- Transports gases, nutrients, waste, cells and hormones throughout the body.
- Transports O2, CO2, nutrients, hormones, heat and wastes.
- Regulates pH, temperature, water content of cells.
- Protects against blood loss through clotting.
