What parts of the human body 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).
What makes up the circulatory system of the body?
These key parts of your circulatory system maintain blood flow to your body so you can survive: 1 blood, made up of cells and plasma 2 the heart, a muscular organ that pumps blood to all parts of your body 3 blood vessels, a network of arteries, capillaries and veins to carry blood pumped by your heart
How many miles are there in the circulatory system?
The network of veins, arteries and blood vessels transports oxygenated blood from the heart, delivers oxygen and nutrients to the body’s cells and then returns deoxygenated blood back to the heart. The system of blood vessels in the human body measure about 60,000 miles (96,560 kilometers).
Is the lymph part of the circulatory system?
Circulatory system. Lymph is essentially recycled excess blood plasma after it has been filtered from the interstitial fluid (between cells) and returned to the lymphatic system. The cardiovascular (from Latin words meaning “heart” and “vessel”) system comprises the blood, heart, and blood vessels.
How many chambers are there in the circulatory system?
The human circulatory system circulates blood through two loops (double circulation) – One for oxygenated blood, another for deoxygenated blood. The human heart consists of four chambers – two ventricles and two auricles.
What are the three main functions of the circulatory system?
- with its nutrients and oxygen to all the body tissues.
- Protection against pathogens.
- Homeostasis maintenance.
What organs make up the circulatory system?
The kidneys, the heart and even skin are all organs. A human actually has two circulatory systems: a short loop running from the heart to the lungs and back, called the pulmonary system, and the systemic circulatory system, which runs from the heart to every other part of the body and returns.
What is the structure and function of the circulatory system?
The structure of the circulatory system is a complex network of pumps and vessels that transports nutrients and oxygen throughout the body. Blood travels in a circular path through the circulatory system. The heart pumps blood to all parts of the body, and within about a minute, that blood returns to the heart to be pumped out once again.
What is the main organ of the circulatory system?
The major organ of the circulatory system is the heart, which pumps the blood into the lungs and throughout the body. The arteries take the blood from the heart out to the different organs.
