What are the two circulatory systems?
Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation (the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again..
What organs are 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.
Why is the human heart called a double pump?
The heart is known as a double pump becasue each half pumps blood around a different circulation system. The right side pumps blood to the lungs, while the left side pumps blood around the body.
Do humans have an open circulatory system?
Humans have a closed circulatory system. The blood is enclosed in the vessels and the heart while circulating. The blood travels through arteries and veins and carries important molecules throughout the body.
What constitutes 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.
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. The heart beats 2.5 billion times during the life of a 75-year-old.
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 do we keep the circulatory system healthy?

What separates the left and right side of heart?
septum (SEP-tum): The septum is a thick wall of muscle that divides the heart. It separates the left and right sides of the heart.
What is the other name for the circulatory system?
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 …
What are the 3 types of circulatory systems?
3 Kinds of Circulation: Systemic circulation. Coronary circulation. Pulmonary circulation.
What is open type of circulatory system?
Open circulatory systems (evolved in insects, mollusks and other invertebrates) pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.
What are the 5 major parts of the circulatory system?
The circulatory system consists of the heart, blood, blood vessels, lymph, and lymphatic vessels.
What is the main organ 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. It usually beats from 60 to 100 times per minute, but can go much faster when necessary.
