What are the main purposes of the cardiovascular system?

The cardiovascular system ( CVS ) moves vital nutrients, gases and hormones around the body. The CVS is made up of the heart, lungs and blood vessels, all working together. The heart functions as a pump. The blood vessels act as pipes, carrying blood through the body.

What is a part 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 hearts function in 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. The arterial circulation delivers blood from the heart to the body, and the venous circulation carries it back to the heart.

What do you need to know about the cardiovascular system?

Introduction to 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.

How does the cardiovascular system control blood pressure?

Several functions of the cardiovascular system can control blood pressure. Certain hormones along with autonomic nerve signals from the brain affect the rate and strength of heart contractions. Greater contractile force and heart rate lead to an increase in blood pressure. Blood vessels can also affect blood pressure.

How does blood travel through the cardiovascular system?

Structures of the Cardiovascular System. Blood Vessels Blood vessels are intricate networks of hollow tubes that transport blood throughout the entire body. Blood travels from the heart via arteries to smaller arterioles, then to capillaries or sinusoids, to venules, to veins and back to the heart.

What is the main function of the cardiovascular system?

The main purpose of the cardiovascular system is to transport blood rich in oxygen and nutrients to cells in the body and transport waste products in the blood to the appropriate system for elimination. The cardiovascular system plays many important roles, including the maintenance of body temperature.

What are the parts and functions of the cardiovascular system?

The cardiovascular system consists of the heart, blood vessels, and blood. This system has three main functions: Transport of nutrients, oxygen, and hormones to cells throughout the body and removal of metabolic wastes (carbon dioxide, nitrogenous wastes).

What are the four main functions of the heart?

Major Functions of the Cardiovascular System. On this page we take a closer look at the four major functions of the cardiovascualr system – transportation, protection, fluid balance and thermoregulation.

What does the cardiovascular system work with?

The cardiovascular system forms a part of the circulatory system, which circulates blood, lymph and oxygen throughout the body. The cardiovascular system works in conjunction with the digestive system to move nutrients throughout the body, and is also closely related to nervous system function.
