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.
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).
Beside above, what organs make up the cardiovascular system quizlet? Terms in this set (11)
- Heart. A hollow, muscular organ that pumps blood throughout the body.
Hereof, what are the 5 main parts of the cardiovascular system?
These are the main roles of the circulatory system. The heart, blood and blood vessels work together to service the cells of the body.

What does the cardiovascular system do?
The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart.
Are veins an organ?
Veins are elastic tubes, or blood vessels, that carry blood from your organs and tissues of the body back to your heart. Each vein is made up of three layers: A layer of membranous tissue on the inside.
What are the functions of human heart?
The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes.
Why is the cardiovascular system important?
The cardiovascular system delivers oxygen, nutrients, hormones, and other important substances to cells and organs in the body. It plays an important role in helping the body meet the demands of activity, exercise, and stress. It also helps maintain body temperature, among other things.
Is blood a tissue or an organ?
Blood is both a tissue and a fluid. It is a tissue because it is a collection of similar specialized cells that serve particular functions. These cells are suspended in a liquid matrix (plasma), which makes the blood a fluid.
What makes up the cardiovascular system?
The heart and circulatory system make up your cardiovascular system. Your heart works as a pump that pushes blood to the organs, tissues, and cells of your body. Blood delivers oxygen and nutrients to every cell and removes the carbon dioxide and waste products made by those cells.
What are the four functions of the heart?
The heart has four chambers: The right atrium receives blood from the veins and pumps it to the right ventricle. The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen. The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.
What are the four main functions of the cardiovascular system?
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 is blood made of?
Your blood is made up of liquid and solids. The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets.
What is the most important part of the cardiovascular system?
Though tiny, the capillaries are one of the most important parts of the circulatory system because it’s through them that nutrients and oxygen are delivered to the cells. In addition, waste products such as carbon dioxide are also removed by the capillaries.
What is the physiology of the cardiovascular system?
Cardiovascular Physiology. The human cardiovascular system is composed of a heart which pumps blood through a closed system of blood vessels. The heart is composed mostly of cardiac muscle, or myocardium. Its primary function is to transport nutrients, water, gases, wastes, and chemical signals throughout the body.
What does the cardiovascular system transport?
The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in
How does the cardiovascular system transport nutrients?
Transporting nutrients to the cells of your body is the job of your circulatory system. Nutrients are transported throughout your body through your blood via capillaries, tiny blood vessels that connect arteries to veins. Nutrients, oxygen and wastes all pass in and out of your blood through the capillary walls.
What is the cardiovascular system is made up of?
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 four chambers of the heart?
The heart has four chambers: two atria and two ventricles. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
