What is circulatory system and its function?

What is circulatory system and its function?

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.

Which organs are in 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).

What are the 14 steps of blood flow?

In summary from the video, in 14 steps, 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 …

What is the correct order of blood flow?

Blood enters the heart through two large veins – the posterior (inferior) and the anterior (superior) vena cava – carrying deoxygenated blood from the body into the right atrium. Blood flows from the right atrium into the right ventricle through the tricuspid valve.

What is the path of blood?

Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.

What is the largest artery in the body?

All arteries of the systemic circulation branch from the aorta (this is the largest artery of the body, with a diameter of 2-3 cm), and divide into progressively smaller vessels.

What is the pathway of circulation?

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.

Which of the following is a correct path of circulation in the body?

The correct path of a drop of blood through the vascular system is right atrium, right ventricle, pulmonary arteries, lungs, pulmonary veins, left atrium, left ventricle, aorta, arteries, arteriorles, capillaries, venules, veins, vena cavae.

What is the largest pathway of the circulatory system?

1. The right Atria receives oxygen poor blood from the body. THIS IS THE LARGEST PATHWAY OF THE CIRCULATORY SYSTEM! Each region of your body has system of arteries supplying it with fresh, oxygen-rich blood.

What is the another name for the 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 does blood get oxygenated?

The heart consists of four chambers in which blood flows. Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium.

In which blood vessels is blood pressure the lowest?

Important: The highest pressure of circulating blood is found in arteries, and gradu- ally drops as the blood flows through the arterioles, capillaries, venules, and veins (where it is the lowest). The greatest drop in blood pressure occurs at the transition from arteries to arterioles.

What is the pathway of deoxygenated blood?

Deoxygenated blood from the body is carried to the heart in the vena cava. It goes into the right atrium, through the tricuspid valve and into the right ventricle. The ventricle pumps the blood through the semilunar valve, into the pulmonary artery and to the lungs.

What is the pathway of blood through the heart and body?

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.

Why is it important for the blood vessels to form a circuit?

Because blood vessels form a circular route, this system is also called the circulatory system. In the pulmonary circuit, blood is pumped from the right ventricle of the heart through the pulmonary arteries, which lead to the lungs. Here the blood gives up carbon dioxide and picks up oxygen.
