What are the four materials distributed by the cardiovascular system?
- Red blood cells – to carry oxygen.
- White blood cells – that make up part of the immune system.
- Platelets – needed for clotting.
- Plasma – blood cells, nutrients and wastes float in this liquid.

What are the 4 types of cardiovascular disease?
Common conditions that can affect the cardiovascular system include coronary artery disease, heart attack, high blood pressure, and stroke. This article explores the cardiovascular system, including its components and their functions. We also outline some common cardiovascular system diseases and their associated treatments.
What are the two circuits of the blood supply system?
Two circuits, the pulmonary and the systemic, consist of arterial, capillary, and venous components. The vascular system is a network of arteries, veins, and capillaries that supplies blood to the tissues of the body.
What is the cardiovascular system responsible for transporting nutrients?
The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. This system is comprised of the heart and the circulatory system.
What 4 things does the cardiovascular system deliver to the cells?
Your circulatory system, also called the cardiovascular system or vascular system, transports oxygen, nutrients and hormones to your body's cells to use for energy, growth and repair. Your circulatory system also removes carbon dioxide and other wastes your cells do not need.
What is distributed by the cardiovascular system?
The cardiovascular system (your heart and blood vessels) supplies your body's organs with oxygen and nutrients so your organs can do their jobs. Your blood vessels also carry carbon dioxide and other waste away for disposal.

The circulatory system consists of four major components:heart.arteries.veins.blood.
What are 6 things transported by the cardiovascular system?
The materials carried by the cardiovascular system include oxygen from the lungs, nutrients from the digestive system, hormones from glands of the endocrine system, and waste materials from cells throughout the body. Transport of these and many other materials is necessary to maintain homeostasis of the body.
What materials are transported through the human circulatory system?
Circulatory systemThe circulatory system delivers oxygen and nutrients to cells and takes away wastes.The heart pumps oxygenated and deoxygenated blood on different sides.The types of blood vessels include arteries, capillaries and veins.
What are the 5 main parts of cardiovascular Systems?
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.

Circulatory System Parts. The circulatory system consists of the heart, blood, blood vessels, lymph, and lymphatic vessels.
What is the cardiovascular system?
Updated September 01, 2019. The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. This system is comprised of the heart and the circulatory system. Structures of the cardiovascular system include the heart, blood vessels, and blood. The lymphatic system is also closely associated with ...
Which system supplies the body with oxygen rich blood and nutrients?
Circulatory System. The circulatory system supplies the body's tissues with oxygen-rich blood and important nutrients. In addition to removing gaseous waste (like CO 2 ), the circulatory system also transports blood to organs (such as the liver and kidneys) to remove harmful substances.
What is the lymphatic system?
The lymphatic system is a vascular network of tubules and ducts that collect, filter, and return lymph to blood circulation. Lymph is a clear fluid that comes from blood plasma, which exits blood vessels at capillary beds. This fluid becomes the interstitial fluid that bathes tissues and helps to deliver nutrients and oxygen to cells. In addition to returning lymph to circulation, lymphatic structures also filter blood of microorganisms, such as bacteria and viruses. Lymphatic structures also remove cellular debris, cancerous cells, and waste from the blood. Once filtered, the blood is returned to the circulatory system.
What is the function of blood?
Blood delivers nutrients to cells and removes wastes that are produced during cellular processes, such as cellular respiration. Blood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells contain enormous amounts of a protein called hemoglobin. This iron-containing molecule binds oxygen as oxygen molecules enter blood vessels in the lungs and transports them to various parts of the body. After depositing oxygen to tissue and cells, red blood cells pick up carbon dioxide (CO 2) for transportation to the lungs where CO 2 is expelled from the body.
What is the process of the heart?
The heart is the organ that supplies blood and oxygen to all parts of the body. This amazing muscle produce s electrical impulses through a process called cardiac conduction. These impulses cause the heart to contract and then relax, producing what is known as a heart beat. The beating of the heart drives the cardiac cycle which pumps blood to cells and tissues of the body.
How does blood travel through the body?
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. Through the process of microcirculation, substances such as oxygen, carbon dioxide, nutrients, and wastes are exchanged between the blood and the fluid that surrounds cells.
Which system of the body transports blood and signals between the different organs?
The circulatory system transports blood along pulmonary and systemic circuits. The pulmonary circuit involves the path of circulation between the heart and the lungs.
Heart attack
A heart attack happens when a part of the heart muscle does not receive enough blood. This can occur due to a blockage, a tear in an artery around the heart, or if the heart requires more oxygen than is available.
Stroke
A stroke is a medical condition in which the blood supply to a part of the brain becomes cut off. This lack of blood supply triggers the death of brain cells.
Heart failure
Heart failure occurs when the heart is unable to pump enough blood to satisfy the body’s needs.
Arrhythmia
An arrhythmia is an abnormal heart rhythm. It may present as a heartbeat that is too quick, too slow, or has a distinctive pattern. Symptoms may include:
Overview
Your heart and many blood vessels in your body make up your cardiovascular system or circulatory system. Your heart uses the far-reaching, intricate network of blood vessels to deliver oxygen and other necessary things to your whole body.
Function
The function of the cardiovascular system is to make sure your body gets the oxygen, nutrients and other things it needs and gets rid of things it doesn’t.
Anatomy
Your heart is located in the middle of your chest. It connects to your blood vessels. They go everywhere throughout your body so they can get oxygen and nutrients to every part of your body. They also take waste away from all the cells in your body.
Conditions and Disorders
Many of the problems with the components of the cardiovascular system have to do with slowdowns or blockages in the blood vessels. Since your blood vessels supply your entire body with oxygen, a blockage in any of the blood vessels makes it harder to deliver that oxygen.
Care
You can help keep your heart and blood vessels healthy in a number of ways, including:
Frequently Asked Questions
Your heart and blood vessels, the parts of the cardiovascular system, are important because they bring oxygen, nutrients and other good things to every cell in your body. They also take away carbon dioxide and waste. This supply of nutrients and the removal of waste is the main function of the cardiovascular system.
How are the heart and ventricles divided?
The heart is divided by septa, or partitions, into right and left halves, and each half is subdivided into two chambers. The upper chambers, the atria, are separated by a partition known as the interatrial septum; the lower chambers, the ventricles, are separated by the interventricular septum. The atria receive blood from various parts of the body and pass it into the ventricles. The ventricles, in turn, pump blood to the lungs and to the remainder of the body.
What are the two circuits of the pulmonary system?
It is a closed tubular system in which the blood is propelled by a muscular heart. Two circuits, the pulmonary and the systemic, consist of arterial, capillary, and venous components.
What is the heart's membranous sac?
The heart is suspended in its own membranous sac, the pericardium. The strong outer portion of the sac, or fibrous pericardium, is firmly attached to the diaphragm below, the mediastinal pleura on the side, and the sternum in front. It gradually blends with the coverings of the superior vena cava and the pulmonary (lung) arteries and veins leading to and from the heart. (The space between the lungs, the mediastinum, is bordered by the mediastinal pleura, a continuation of the membrane lining the chest. The superior vena cava is the principal channel for venous blood from the chest, arms, neck, and head.)
What are the grooves on the external surface of the heart called?
External surface of the heart. Shallow grooves called the interventricular sulci, containing blood vessels, mark the separation between ventricles on the front and back surfaces of the heart. There are two grooves on the external surface of the heart.
What is the vascular system?
The vascular system is a network of arteries, veins, and capillaries that supplies blood to the tissues of the body. Encyclopædia Britannica, Inc. See all videos for this article. The primary function of the heart is to serve as a muscular pump propelling blood into and through vessels to and from all parts of the body.
Which veins drain blood from the heart?
Three veins empty into the right atrium, the superior and inferior venae cavae, bringing blood from the upper and lower portions of the body, respectively, and the coronary sinus, draining blood from the heart itself. Blood flows from the right atrium to the right ventricle.
How big is the heart?
The adult human heart is normally slightly larger than a clenched fist, with average dimensions of about 13 × 9 × 6 cm (5 × 3.5 × 2.5 inches) and weight approximately 10.5 ounces (300 grams). It is cone-shaped, with the broad base directed upward and to the right and the apex pointing downward and to the left.
