Three types of circulation in the body
Summary
TLDRThis video from moomoomath and science explores the three vital circulation systems in the human body: blood circulation, which includes pulmonary and systemic circulation, and lymphatic circulation. It explains how blood transports oxygen and nutrients while removing waste through the pulmonary cycle to the lungs and back, and systemic circulation to the rest of the body. The video also details the roles of arteries, veins, and capillaries, and introduces the lymphatic system's function in absorbing and filtering lymph, a fluid derived from plasma leakage, playing a crucial role in our immune response.
Takeaways
- 🩸 The human body has three types of circulation: lymphatic, pulmonary, and systemic.
- 💓 Blood circulation is essential for transporting oxygen, waste, sugar, and other vital substances throughout the body.
- 🔄 Pulmonary circulation involves the blood's journey to and from the lungs to exchange oxygen for carbon dioxide.
- 🫁 Blood enters the right atrium from the vena cava, travels to the right ventricle, and into the lungs via pulmonary arteries.
- 🔄 In the lungs, oxygen is exchanged for carbon dioxide at alveoli, and the oxygen-rich blood returns to the heart through pulmonary veins.
- 🌐 Systemic circulation is the process by which blood is pumped throughout the body after returning from the lungs.
- 🔄 Systemic blood circulation starts from the left atrium, moves to the left ventricle, and is distributed via the aorta to the rest of the body.
- 🔴 Arteries are blood vessels that carry blood away from the heart, typically with oxygenated blood, and are often depicted in red.
- 🔵 Veins are vessels that return deoxygenated blood from the body to the heart, and are usually shown in blue.
- 🔄 Capillaries are the small vessels that connect arteries and veins, facilitating the exchange of nutrients and waste.
- 💧 The lymphatic system absorbs and transports lymph, a fluid resulting from plasma leakage from capillaries.
- 🛡️ Lymph nodes act as filtering stations and are part of the body's immune defense system.
Q & A
What are the three types of circulation mentioned in the video?
-The three types of circulation mentioned in the video are lymphatic circulation, pulmonary circulation, and systemic circulation.
What is the primary function of blood circulation?
-The primary function of blood circulation is to carry oxygen, remove waste, transport sugar, and other essential items throughout the body.
How does pulmonary circulation differ from systemic circulation?
-Pulmonary circulation involves the movement of blood to and from the lungs for gas exchange, while systemic circulation refers to the circulation of blood throughout the rest of the body.
What are the two main components of blood that are exchanged in the lungs during pulmonary circulation?
-During pulmonary circulation, carbon dioxide is exchanged for oxygen in the lungs.
Where does the blood enter the heart to begin pulmonary circulation?
-Blood enters the right atrium of the heart from the superior and inferior vena cava to begin pulmonary circulation.
What is the role of the alveoli in the lungs during pulmonary circulation?
-The alveoli are tiny air sacs in the lungs where oxygen is exchanged for carbon dioxide during pulmonary circulation.
Which blood vessels are responsible for carrying blood away from the heart?
-Arteries are the blood vessels that carry blood away from the heart to all parts of the body.
What is the primary function of veins in the circulatory system?
-Veins are responsible for carrying blood, most of which is deoxygenated, from the tissues back towards the heart.
What are capillaries and how do they relate to arteries and veins?
-Capillaries are tiny blood vessels that connect arteries and veins, allowing for the exchange of nutrients, oxygen, and waste between the blood and body tissues.
What is the lymphatic system responsible for absorbing and transporting?
-The lymphatic system is responsible for absorbing and transporting lymph, a clear fluid that results from plasma leaking out of capillaries.
How does the lymphatic system contribute to the body's natural defense system?
-The lymphatic system contributes to the body's natural defense system by transporting lymph through lymphatic vessels to lymph nodes, which act as filtering stations for the body.

Highlights
Introduction to the three types of circulation in the human body: blood circulation, lymphatic circulation, and the two types of blood circulation - pulmonary and systemic.
Blood circulation's role in transporting oxygen, waste, sugar, and other essentials throughout the body.
Pulmonary circulation involves blood traveling to and from the lungs to exchange oxygen for carbon dioxide.
Description of the path blood takes during pulmonary circulation, from the right atrium to the lungs and back via the pulmonary veins.
Systemic circulation is the process of blood traveling throughout the body after leaving the lungs.
The journey of blood in systemic circulation, from the left atrium, through the left ventricle, and out via the aorta.
Differentiation between the three types of blood vessels: arteries, veins, and capillaries, and their respective functions.
Arteries carry oxygenated blood away from the heart and are typically depicted in red.
Veins transport deoxygenated blood back to the heart, with most veins carrying this type of blood.
Capillaries are small vessels that connect arteries and veins, facilitating the exchange of nutrients and waste.
Introduction to lymphatic circulation as the absorption and transportation of lymph, a clear fluid derived from plasma.
Explanation of how the lymphatic system reabsorbs plasma that leaks out of capillaries daily.
Lymphatic vessels have smooth muscles and valves that aid in moving lymph throughout the body.

welcome to moomoomath and science in
this video I'd like to talk about three
types of circulation found in the human
body lymphatic circulation and two types
of blood circulation pulmonary
circulation and systemic circulation
let's look at blood circulation first
your blood is responsible for carrying
oxygen waste sugar and other important
items throughout your body in order to
carry oxygen and eliminate carbon
dioxide it must travel to the lungs
pulmonary circulation is when blood
travels to the lungs and back blood
enters the right atrium from the
superior and inferior vena cava it
travels to the right ventricle and into
the lungs through the pulmonary arteries
in the lungs oxygen is exchanged for
carbon dioxide at tiny air sacs called
alveoli and then returns to the heart
through the pulmonary veins
up next is systemic circulation which is
circulation throughout the body as blood
returns from the lungs it enters the
left atrium and then travels to the left
ventricle then passes out of the aorta
and into the rest of the body this
circulation is called
systemic circulation there are three
types of vessels that are used for blood
circulation an artery is a blood vessel
that takes blood away from the heart to
all parts of the body most arteries but
not all carry oxygenated blood and
arteries are usually shown as red
vessels veins are blood vessels that
carry blood towards the heart most veins
but not all carry deoxygenated blood
from the tissues back to the heart
and finally you have capillaries which
are tiny vessels that connect arteries
and veins the third type of circulation
is called lymphatic circulation the
lymphatic system absorbs and transports
lymph lymph is a clear fluid that is a
result of plasma leaking out of
capillaries as plasma moves out of
capillaries some of it is not reabsorbed
you lose about 3 liters of plasma a day
the lymphatic system reabsorbs this
fluid once this plasma has leaked out of
capillaries and enters lymphatic vessels
it is called lymph the lymphatic vessels
have smooth muscles and valve that help
move the limp throughout your body
once the lymph enters the vessels and
then transport it to lymph nodes that
act as filtering stations in the bodies
and these lymph nodes are part of your
body's natural defense system so there
we go three types of circulation found
in your body lymphatic pulmonary and
systemic thanks for watching and
