What is cardiovascular system simple definition?

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 is the 3 parts of 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.

What are the 5 main parts of the cardiovascular 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 the structure and function of the cardiovascular system?

Your cardiovascular system consists of your heart, blood vessels and blood, which function together as a liquid transport network. This system delivers oxygen and nutrients to your body and picks up waste products to be eliminated.

What are the 3 main functions of the cardiovascular system?

Circulates OXYGEN and removes Carbon Dioxide. Provides cells with NUTRIENTS. Removes the waste products of metabolism to the excretory organs for disposal.

What is the structure of the 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.

What are the two types of circulation?

There Are Two Types of Circulation: Pulmonary Circulation and Systemic Circulation.

What are the 6 phases of the cardiac cycle?

Detailed descriptions of each phase can be obtained by clicking on each of the seven phases listed below.

• Phase 1 – Atrial Contraction.
• Phase 2 – Isovolumetric Contraction.
• Phase 3 – Rapid Ejection.
• Phase 4 – Reduced Ejection.
• Phase 5 – Isovolumetric Relaxation.
• Phase 6 – Rapid Filling.
• Phase 7 – Reduced Filling.

What are the 4 main functions of the heart?

The four main functions of the heart are:

• Pumping oxygenated blood to other body parts.
• Pumping hormones and other vital substances to different parts of the body.
• Receiving deoxygenated blood and carrying metabolic waste products from the body and pumping it to the lungs for oxygenation.
• Maintaining blood pressure.

What is the basic structure of the cardiovascular system?

The cardiovascular system is sometimes called the blood-vascular, or simply the circulatory, system. It consists of the heart, which is a muscular pumping device, and a closed system of vessels called arteries, veins, and capillaries.

What is the structure of cardiovascular system?

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 your body. The blood entering the right side of your heart is low in oxygen.

What is the main functions of the circulatory system?

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 are the two main components of the circulatory system?

What Are the Parts of the Circulatory System? Two pathways come from the heart: The pulmonary circulation is a short loop from the heart to the lungs and back again. The systemic circulation carries blood from the heart to all the other parts of the body and back again.

What are types of circulation explain?

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 different types of circulation?

This type of circulatory system has a separate systemic circulation and pulmonary circulation. Systemic circulation – The flow of oxygenated blood from the left ventricle of the heart to various parts of the body and deoxygenated blood from various parts of the body to the right atrium is called systemic circulation.

What are the 7 phases of the cardiac cycle?

The different phases of the cardiac cycle involve:

• Atrial diastole.
• Atrial systole.
• Isovolumic contraction.
• Ventricular ejection.
• Isovolumic relaxation.
• Ventricular filling.

What is cardiac cycle explain with diagram?

The cycle diagram depicts one heartbeat of the continuously repeating cardiac cycle, namely: ventricular diastole followed by ventricular systole, etc. —while coordinating with atrial systole followed by atrial diastole, etc….Cardiac cycle.

What is 1 function of the heart?

It pumps blood throughout your body, controls your heart rate and maintains blood pressure. Your heart is a bit like a house. It has walls, rooms, doors, plumbing and an electrical system. All the parts of your heart work together to keep blood flowing and send nutrients to your other organs.

What are the two circuits of the cardiovascular system?

The blood vessels of the body are functionally divided into two distinctive circuits: pulmonary circuit and systemic circuit.

What is the main function of the cardiovascular system?

The cardiovascular system works in conjunction with the respiratory system to deliver oxygen to the tissues of the body and remove carbon dioxide.

What is cardiovascular system and its function?
