The Circulatory System

Interesting Facts

The heartbeat is strong enough to squirt blood 30 feet
The longer a boy’s ring finger is, the less likely they are to have a heart attack (according to one study)
The human heart beats ~35 million times per year
The heart pumps ~1,000,000 barrels of blood in a lifetime
Most heart attacks occur between 8-9 a.m.
The blue whale has the

largest heart –

it weighs ~ one ton

The hummingbird has a

heart that beats

1,000 times per minute

Your entire volume of blood goes through your whole body once every minute
Humans have ~60,000 miles of blood vessels in their bodies (more than twice the circumference of the earth!)
Your heart beats 100,000 times and pumps ~2,000 gallons of blood every day
Pig and baboon hearts have been transplanted into humans

Exploration

This is a picture of the

bottom of the human tongue.

Take a look at the bottom of your lab partner’s tongue (if they will let you) and see if you can find…

◦The veins –thick blue lines

◦The arteries –thick pink lines

◦The capillaries –tiny thin lines

What provides the force to cause the blood to circulate through the body?

The heart is composed of cardiac muscle

which is part of the autonomic (automatic)

nervous system.

When it beats (flexes) blood is pushed through

the cardiovascular/circulatory system.

A collection of vessels and the muscles that

control the flow of blood through the body .

What is the Circulatory System?

◦The organ that pumps blood through the circulatory system.

Size of a fist;
Weighs less than a pound
In thorax; flanked by lungs; rests on diaphragm
Bottom: apex

Receive blood into heart

and pass it on to the ventricles

Collect blood from the heart

and pass it on to the lungs, aorta, and

push it out into the body

Larger than the atria as more muscle is needed to pump greater volumes of blood

Why is the left ventricle bigger than the right ventricle?

Because the right ventricle only has to push blood out to the lungs which are not very far away in comparison to the left ventricle which must push out blood into the rest of the body.

Types of Blood Vessels

Arteries are thick walled and muscular vessels
Arteries move oxygen rich blood away from the heart (with the exception of the Pulmonary artery)
How is the structure of an artery related to its function?
Blood vessels that carry blood away from the heart.
They have thick, elastic walls made of connective tissue and smooth muscle that can expand in size
Most carry oxygenated blood ( red )
Damaged arteries spurt in time to heartbeat
Veins are thin walled vessels and have flexible walls. Veins also have one way valves.
Veins bring deoxygenated blood back to the heart
How does the structure of a veins relate to its function?
Blood vessels that carry blood back to the heart.
Carry blood at low pressure
Have valves to prevent backflow of blood against gravity
Most carry de-oxygenated blood ( purple )
Damaged veins ooze blood

◦Smaller blood vessels that extend from arteries to capillaries.

Capillaries

◦The smallest vessels in the body. They are only one cell thick and allow oxygen and carbon dioxide to be exchanged from blood to body tissues.

◦Smaller blood vessels that extend from capillaries to veins.

Capillaries are only one cell thick and have very flexible walls.
Capillaries connect arteries (arterioles) to veins (venules) and allow for gas , nutrients , and waste exchange .
Connect arteries and veins
Walls are one cell thick
Allow exchange of gases through thin walls
Drop off oxygen delivered from heart by arteries
Pick up CO 2 and send it to the heart thru veins

How Blood Travels thru Vessels

Blood Vessels

Arteries: carry blood AWAY from the heart
Veins: carry blood IN to the heart
Capillaries: connect arteries to veins & exchange gases with tissues

Circulatory System PowerPoint Template

The Circulatory System PowerPoint Template is a health literacy presentation deck. It offers a collection of diagrams featuring functions of the cardiovascular system. These diagrams include the anatomy of blood vessels in the human body, their structure, arteries of heart, and cells. There are additional three slides of myocardial infarction, stroke, and varicose veins for heart conditions including structural problems and blood clots.

The circulatory system known as cardiovascular or vascular is an organ system of blood circulation in the body. It is made up of a network of blood vessels that transport blood to and from the heart. The blood vessels that carry blood away from the heart are called arteries and veins take the blood back to the heart. This system of transporting blood carries oxygen, nutrients, and hormones to cells.

The PowerPoint templates of Circulatory system diagrams are educational presentations. These templates can help communicate hearth health concepts to medical students or create presentations on specific topics such as a myocardial infarction PPT. The label diagrams of blood vessels and hearth display the components in a clear manner. The health professionals benefit from presentations of the cardiovascular system and related topics to discuss new medical developments. Users can copy these diagrams propose a convincing case for treatments or medical devices to venture capitalists and investors.

The Circulatory System PowerPoint Template is designed with vector images to illustrate the anatomy of the human heart. The vector-based graphics let users customize PowerPoint shapes by changing colors, sizes, and shape effects. Users benefit from editable graphics to recreate more high-quality diagrams by combining graphics from multiple slides. The slides of cell types are reusable in many medical presentations about healthy blood cells or diseases.
