What are the 7 steps of the circulatory system?

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 is the function of the circulatory system Short answer?

The main function of the circulatory system is to provide oxygen, nutrients and hormones to muscles, tissues and organs throughout your body. Another part of the circulatory system is to remove waste from cells and organs so your body can dispose of it.

How does the circulatory system work quizlet?

The circulatory system carries oxygen to all of the body’s cells and transports carbon dioxide from the rest of the body to the lungs, where it is exhaled. The function of the circulatory system is to transport O2 and nutrients to body cells and to carry oxygen-poor blood and CO2 back to the heart and lungs.

What is the process of blood 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.

What is the correct order in the circulatory system?

Explanation: 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.

How does the circulatory system work answers?

The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

What are the three functions of the circulatory system quizlet?

Its functions include: 1) carries food and oxygen to the different cells of the body; 2) carries body wastes away; 3) protects the body from diseases; and 4) serves as the body’s defense system.

How does the circulatory system of the human body work?

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.

How does the circulatory system work like a tree?

The arteries carry blood away from the heart; the veins carry it back to the heart. The system of blood vessels resembles a tree: The “trunk” – the main artery (aorta) – branches into large arteries, which lead to smaller and smaller vessels. The smallest arteries end in a network of tiny vessels known as the capillary network.

How does the pulmonary circulation of the heart work?

The pulmonary circulation is where the fresh oxygen we breathe in enters the blood. At the same time, carbon dioxide is released from the blood. Blood circulation starts when the heart relaxes between two heartbeats: blood flows from both atria (the upper two chambers of the heart) into the ventricles (the lower two chambers) which then expand.

How many chambers are there in the circulatory system?

The human circulatory system circulates blood through two loops (double circulation) – One for oxygenated blood, another for deoxygenated blood. The human heart consists of four chambers – two ventricles and two auricles.
