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 are the 5 parts of the circulatory system?
- Blood. Blood consists of:
- The heart. The heart pumps blood around the body. …
- The right side of the heart. …
- The left side of the heart. …
- Blood vessels. …
- Arteries. …
- Capillaries. …
- Veins.
Where are the lungs in the circulatory system?
The Circulatory System. The lungs are a pair of elastic, spongy organs used in breathing. In humans the lungs take up a lot of the chest cavity. They are
located just behind, and to either side of, the heart
.
What are the main parts of circulatory system?
The circulatory system is composed of
the heart and blood vessels
, including arteries, veins, and capillaries.
Are lungs in the circulatory system?
CIRCULATORY SYSTEM
The blood then travels through the lungs to exchange carbon dioxide for new oxygen. The heart is a pump which moves the blood. The arteries and veins are the pipes through which the blood flows. The lungs
provide a place to exchange
carbon dioxide for oxygen.
What do lungs have to do with the circulatory system?
The lungs' main role is
to bring in air from the atmosphere and pass oxygen into the bloodstream
. From there, it circulates to the rest of the body.
What are the 3 types of circulation?
- Systemic circulation.
- Coronary circulation.
- Pulmonary circulation.
Which is the most important part of the circulatory system?
The heart
is the most important part of the circulatory system because without it blood would not be pumped throughout the body. The blood vessels are the most important part as they carry the blood with nutrients and oxygen to the cells.
Why is it called the circulatory system?
As the name implies,
blood contained in the circulatory system is pumped by the heart around a closed circle or circuit of vessels as it passes again and again through the various “circulations” of the body
.
Why the circulatory system is important?
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. These roadways travel in one direction only, to keep things going where they should.
What will reduce gas exchange in the lungs?
The lungs normally have a very large surface area for gas exchange due to the alveoli.
Diseases such as emphysema
lead to the destruction of the alveolar architecture, leading to the formation of large air-filled spaces known as bullae. This reduces the surface area available and slows the rate of gas exchange.
What are the benefits of having the lungs inside the rib cage close to the heart?
The lungs also act as “packing foam” inside the rib cage,
supporting and protecting the vital heart that delivers half of its output to the lungs
, and the other half to the rest of the body.
Do the lungs cover the heart?
The membrane
continues over the lung
, where it is called the visceral pleura, and over part of the esophagus, the heart, and the great vessels, as the mediastinal pleura, the mediastinum being the space and the tissues and structures between the two lungs.
What are the four major parts of 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 are the 4 types of circulation?
Systemic circulation, pulmonary circulation and portal circulation
.
How is the circulatory system protected?
Protection: The cardiovascular system protects
the body through its white blood cells
. White blood cells clean up cellular debris and fight pathogens that have entered the body.
