How does blood circulate in our body?
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 main function of blood?
Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues. forming blood clots to prevent excess blood loss. carrying cells and antibodies that fight infection.
What would happen without the circulatory system?
Blood delivers oxygen to all the body’s cells. To stay alive, a person needs healthy, living cells. Without oxygen, these cells would die. If that oxygen-rich blood doesn’t circulate as it should, a person could die.
What is another name of circulatory system?
cardiovascular systemcardiovascular system: The heart and circulatory system (also called the cardiovascular system) make up the network that delivers blood to the body’s tissues.
Why is the circulatory system important for respiration?
Gas exchange between tissues and the blood is an essential function of the circulatory system. In humans, other mammals, and birds, blood absorbs oxygen and releases carbon dioxide in the lungs. Thus the circulatory and respiratory system, whose function is to obtain oxygen and discharge carbon dioxide, work in tandem.
What happens when blood circulation increases?
You’ll maintain healthy blood and oxygen flow throughout the body, allowing your lungs, heart and muscles to function properly and efficiently. You’ll fight off and avoid potential diseases and sicknesses. With good circulation, the white blood cells in your immune system will be transported around the body as needed.
What are the major organs of the circulatory system quizlet?

How does the circulatory system fight disease?
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 …
Which is the correct direction of blood flow?
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium.
How long is the circulatory system?
The circulatory system in the human body stretches 66,000 miles, more than two and a half times the circumference of the Earth.
What organs can be found in the 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.
How do we keep the circulatory system healthy?
Tips for circulatory healthMaintain a healthy weight.Don’t smoke.Exercise a minimum of 30 minutes a day, most days of the week.Maintain a healthy, low-fat, low-cholesterol diet with more fruits, vegetables, and whole grains.Avoid trans fats and saturated fats, which are often found in processed foods and fast food.More items…

Is High Blood Pressure a circulatory disorder?
Many circulatory system diseases are linked to each other. For example, high blood pressure damages the blood vessels, which can lead to other circulatory problems.
What are the 14 body systems?
These 14 systems are the Musculoskeletal system; Organs of Special Sense (optical); Auditory; Infectious Diseases, Immune Disorders, and Nutritional Deficiencies; Respiratory system; Cardiovascular system; Digestive system; Genitourinary System; Hemic and Lymphatic system; Skin; Endocrine system; Neurological …
Is the circulatory system an open or closed system?
The circulatory system is effectively a network of cylindrical vessels (the arteries, veins, and capillaries) that emanate from a pump (the heart). In all vertebrate organisms, as well as some invertebrates, this is a closed-loop system in which the blood is not moving freely in a cavity.
What is the main 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 two organ systems that are involved in the excretion of wastes from the body?
Excretory systems regulate the chemical composition of body fluids by removing metabolic wastes and retaining the proper amounts of water, salts, and nutrients. Components of this system in vertebrates include the kidneys, liver, lungs, and skin.
Why is the circulatory system important for good health?
The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. These roadways travel in one direction only, to keep things going where they should.
How many types of circulatory systems are there?
1. There Are Two Types of Circulation: Pulmonary Circulation and Systemic Circulation. Pulmonary circulation moves blood between the heart and the lungs.

What is the most important part of the circulatory system?
The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body.
What happens if blood flow increases?
Vasodilation is an important aspect of inflammation. It increases blood flow to the area and also increases the permeability, or leakiness, of the blood vessel walls. Both of these factors help immune cells to more effectively reach the affected area.
What are the 3 major parts of the circulatory system?
An Introduction to the Cardiovascular System This system has three main components: the heart, the blood vessel and the blood itself.
