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 12 steps of blood flow through the heart?
- SUPERIOR AND INFERIOR VENA CAVA. …
- RIGHT ATRIUM. …
- TRICUSPID VALVE. …
- RIGHT VENTRICLE. …
- PULMONARY SEMILUNAR VALVE. …
- RIGHT & LEFT PULMONARY ARTERY. …
- RIGHT & LEFT PULMONARY VEIN. …
- LEFT ATRIUM.
What are the 4 main 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.
How the heart works step by step?
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
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) …
Which is the sequence of correct blood flow?
Two pulmonary veins come from each lung and pass O2-rich blood to left atrium. Blood enters left ventricle from the left atrium. The left ventricle pumps blood into the aorta which in turn branches and delivers blood to the major body regions and organs. So, the correct sequence is C.
What is circulatory system explain?
The system that contains the heart and the blood vessels and moves blood throughout the body. This system helps tissues get enough oxygen and nutrients, and it helps them get rid of waste products.
How is respiratory system linked to the circulatory system?
The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
How the circulatory system works ks2?
The circulatory system is a network within the body that consists of blood, blood vessels, and the heart. The reason for this network is to supply tissues in the body with nutrients and oxygen, transport hormones and remove waste products that the body doesn’t need.
What is circulatory system explain with diagram?
The atria contracts and pumps the blood to the right ventricle. The right ventricle pumps the blood via pulmonary arteries to lungs for oxygenation. The oxygenated blood from the lungs moves to the heart via pulmonary veins. From pulmonary veins, blood enters in the left atrium and then left ventricle.
What are the 5 major parts of the circulatory system?
The cardiovascular system, also known as the circulatory system, includes the heart, arteries, veins, capillaries and blood. The heart functions as the pump that moves blood through the body.
What is circulatory system parts and functions?
Your circulatory system, also known as your cardiovascular system, is made up of your heart and blood vessels. It works to transport oxygen and other nutrients to all the organs and tissues in your body. It also works to remove carbon dioxide and other waste products.
What systems work with the circulatory system?
Your cardiovascular system works to circulate your blood while your respiratory system introduces oxygen into your body.
What is the circulatory system ks3?
The circulatory system is the heart and all the blood vessels in the body which carry cells and substances to all its parts.
What is circulatory system class 7th?
Circulatory system refers to the heart and a network of blood vessels that move blood, nutrients and oxygen throughout the body. The circulatory system consists of the heart, capillaries, arteries and veins.
What are the two main parts of the circulatory system ks2?
- Blood – this liquid circulates around your body carrying food, water, oxygen and waste products.
- Blood Vessels – these are the tubes that blood flows through.
- Heart – this vital organ pumps blood through the blood vessels.
Which 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.
What are 3 interesting facts about the circulatory system?
- The heart beats 2.5 billion times during the life of a 75-year-old.
- The heart expels 2 ounces of blood with each beat, five quarts of blood each minute, 220 million quarts in 70 years.
What are the 3 main components of circulatory system?
- Blood. …
- Blood Vessels. …
- Heart.
What are the 6 functions of the circulatory system?
- Circulates OXYGEN and removes Carbon Dioxide.
- Provides cells with NUTRIENTS.
- Removes the waste products of metabolism to the excretory organs for disposal.
- Protects the body against disease and infection.
- Clotting stops bleeding after injury.
How important is the circulatory system?
The circulatory system does a very important job in your body. It carries oxygen and essential nutrients to all cells around the body in arteries and carries the waste products and carbon dioxide in veins. The average human body contains over 60,000 miles of blood vessels.
How does the circulatory system work with the excretory system?
The circulatory system helps the excretory system by giving the kidney and other organs blood. The heart is the main organ in the circulatory system and is depended on all the time. It pumps waste like carbon dioxide, salt, and urea with our blood until it spreads to our kidneys, where it is filtered out.
What are the functions of circulatory system class 10?
- It helps in sustaining all the organ systems.
- It transports blood, nutrients, oxygen, carbon dioxide and hormones throughout the body.
- It protects cells from pathogens.
- It acts as an interface for cell-to-cell interaction.
How does blood flow through the heart step by step class 10?
- 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.
What is circulation class 8?
Circulatory system, as the name itself, implies circulates food, water, and air throughout the body. The most important means of transport in the circulatory system is the blood. Blood is a fluid connective tissue present in our body which circulates food, water, and air to different parts of the body.
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.
How does the circulatory system maintain homeostasis?
The circulatory system maintains homeostasis, by the controlled and continuous flow of blood that reaches each cell in the body. This allows the mechanisms within the circulatory system to ensure that every cell maintains a constant and balanced internal environment!
