Three types of circulation in the body

Summary

This 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.

🩺 Human Body Circulation Systems

This paragraph introduces the three main types of circulation in the human body: blood circulation, which includes pulmonary and systemic circulation, and lymphatic circulation. Blood circulation is essential for transporting oxygen, nutrients, and waste products. Pulmonary circulation describes the path blood takes to and from the lungs for oxygenation, while systemic circulation covers the distribution of blood throughout the body. The paragraph also explains the role of different blood vessels: arteries, veins, and capillaries. Lastly, it touches on the lymphatic system's function in absorbing and transporting lymph, a fluid derived from plasma leakage, and its importance in the body's defense mechanism through lymph nodes.

Keywords

💡Circulation

Circulation refers to the movement of fluids, such as blood and lymph, within the body. In the context of the video, it is the central theme, encompassing three distinct systems: blood, lymphatic, and pulmonary circulation. The script explains how these systems are crucial for the transport of oxygen, nutrients, and waste products throughout the body.

💡Blood Circulation

Blood circulation is the process by which blood travels through the heart and blood vessels to supply oxygen and nutrients to the tissues and remove waste products. The video script delves into two types of blood circulation: pulmonary and systemic, highlighting their importance in maintaining life functions.

💡Pulmonary Circulation

Pulmonary circulation is the pathway that blood takes to reach the lungs for the exchange of oxygen and carbon dioxide. The script explains that deoxygenated blood from the body enters the right side of the heart, travels to the lungs via the pulmonary arteries, and returns oxygenated through the pulmonary veins.

💡Systemic Circulation

Systemic circulation is the process by which oxygen-rich blood is transported from the heart to the rest of the body and then returns deoxygenated blood back to the heart. The video script describes how blood from the lungs enters the left atrium, moves to the left ventricle, and is then pumped out through the aorta to circulate throughout the body.

💡Alveoli

Alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place. The script mentions that in the lungs, oxygen is exchanged for carbon dioxide at the alveoli, which is a critical step in the respiratory process.

💡Arteries

Arteries are blood vessels that carry blood away from the heart to the rest of the body. The video script clarifies that most arteries carry oxygenated blood, with the exception of the pulmonary artery, which carries deoxygenated blood to the lungs.

💡Veins

Veins are blood vessels that return blood to the heart from various parts of the body. The script indicates that most veins carry deoxygenated blood, except for the pulmonary veins, which carry oxygenated blood from the lungs to the heart.

💡Capillaries

Capillaries are the smallest blood vessels that connect arteries and veins, allowing for the exchange of substances between the blood and the body's tissues. The video script explains their role in connecting the larger vessels and facilitating the transfer of oxygen, nutrients, and waste products.

💡Lymphatic Circulation

Lymphatic circulation is the process by which the lymphatic system absorbs and transports lymph, a fluid derived from plasma that has leaked out of capillaries. The script describes how the lymphatic system reabsorbs this fluid and transports it through lymphatic vessels to lymph nodes, which filter the lymph and are part of the body's immune system.

💡Plasma

Plasma is the liquid component of blood that carries cells, nutrients, hormones, and waste products. The video script mentions that about 3 liters of plasma leak out of capillaries daily, and this leaked plasma becomes lymph when it enters the lymphatic vessels.

💡Lymph Nodes

Lymph nodes are small, bean-shaped structures that act as filtering stations for the lymphatic fluid. The script explains that lymph nodes are part of the body's natural defense system, playing a crucial role in the immune response by filtering out harmful substances from the lymph.

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.

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
