An introduct ion to the projectHello and welcome to The Circulatory System, a Biology project by

two Einstein students, Cici Donna Real and Mika Hara.

In this project, we were tasked to make a Microsoft PowerPoint

presentation about a system of our choice, and describe the

system thoroughly throughout the presentation.

Thereafter, we chose to present the circulatory system because it is a

recently covered topic and a quite challenging subject to

explain.

Our layout in this PowerPoint presentation is very minimal and easy

to navigate through. Start browsing this project by clicking next

or by choosing a slide from the navigation located at the right

side of this slide.

Thank you for reading this introduction and wehope you enjoy our presentation!

What IS the circulatory system?The Circulatory System is responsible for transporting

materials throughout the entire body. It transports

nutrients, water, and oxygen to your billions of body cells

and carries away wastes such as carbon dioxide that body

cells produce. It is an amazing highway that travels through

your entire body connecting all your body cells.

FunctionsThere are several functions of the circulatory system that must not

be forgotten:

Carry oxygen from lungs to tissues and carbon dioxide from tissues

to lungs thereby aiding in the exchange of gases. Supply ofoxygen is needed for proper function of the cells. Removal of

carbon dioxide is also equally essential as it becomes toxic to

cells when present in high amount.

Help in fighting against infections by the defense cells- the

granulocytes and agranulocytes.

Prevent over bleeding by forming blood clot by the platelets.

Helps to maintain pH of the blood by buffering system present

Par tsThe circulatory system is divided into three major parts, namely: the

heart, the blood, and the blood vessels.

The Heart

Theh

eart is an amazingorgan. The heart beats

about 3 billion times

during an average

lifetime. It is a muscle

about the size of your fist.

The heart is located in the

center of your chest

slightly to the left. Its job

is to pump your blood and

keep the blood moving

throughout your body.

It is your job to keep your

heart healthy, and there

are many things you can

do to keep it maintained.

The Blood

The blood is a substancethat is constantly flowing

through our bodies.

Your blood is pumped by

the heart. It travels

through blood vessels

within our body. Your

blood carries various

materials- such as

nutrients, water, oxygen,

and waste products.

Your blood is not merely a

red substance- it is made

up of liquids, solids, and

small amounts of oxygen

and carbon dioxide.

The Blood Vessels

There are three types ofblood vessels: arteries,

capillaries and veins.

Arteries carry oxygen

away from the heart.

Capillaries connect

arteries to veins.

Nutrients, oxygen, and

water use the capillary

walls as a passage.

Veins carry blood back to

your heart.

The Heart The heart has four valves which help in preventing back flow of

blood during systole. They ensure a one way traffic of blood. The

valves are made up of flaps of connective tissue. There are four main

heart valves. Two of them lie in the opening of the atria and

ventricles. The other two valves lie at the beginning of the two great

arteries. The atrioventricular valves are present between each

atrium and ventricle. They help in preventing back flow of blood into

the atria during ventricular contraction. The left atrioventricular

valve is called the bicuspid valve and separates the left atrium and

the left ventricle. The right atrioventricular valve is called the

tricuspid valve and separates the right atrium from the right

ventricle. The pulmonary valve is a valve which separates the right

ventricle from the pulmonary artery. The aortic valve is responsible

for separating the right ventricle from the ascending aorta.

The BloodBlood, a vital fluid found in humans and other animals that provides

important nourishment to all body organs and tissues and

carries away waste materials. Sometimes referred to as the

river of life, blood is pumped from the heart through a network

of blood vessels collectively known as the circulatory system.

There are three classes of blood cells: red blood cells, white blood

cells, and platelets.

-continue

Red blood cells are responsible for carrying

oxygen and carbon dioxide. Red blood cells

pick up oxygen in the lungs and transport it to

all the body cells. Afterwards, it gathers up

carbon dioxide and transports them back to

the lungs where it is removed from the body

when we exhale. There are approximately

five million red blood cells in one drop of

blood.

The BloodWhite blood cells or leukocytes are cells of the

immune system involved in defending the

body against both infectious diseases and

foreign materials. There are five different and

diverse types of leukocytes, but they are all

produced and derived from a multiponentcell in the bone marrow known as a

hematopoietic stem cell.

Platelets are blood cells that help stop bleeding.

When we cut ourselves, we have broken a blood cells

and the blood leaks out. In order to plug up the holes

where the blood is leaking from the platelets start to

stick to the opening of the damaged blood cells. As

the platelets stick to the opening of the damagedvessel they attract more platelets, fiber and other

blood cells to help form a plug to seal the broken

blood vessel. When the platelet plug is completely

formed the wound stops bleeding.

The BloodAnother part of the blood is the plasma. Plasma is the liquid part of

the blood, and approximately half of your blood is made out of

plasma. The plasma carries the blood cells and other

components throughout the body. Plasma is made in the liver.

The B lood VesselsThe blood vessels are the part of the circulatory system that

transport blood throughout the body. There are three major

types of blood vessels: thearteries, which carry the blood away

from the heart; the capillaries, which enable the actual

exchange of water and chemicals between the blood and the

tissues; and the veins, which carry blood from the capillaries

back toward the heart.

Arteries carry oxygen away from the heart.

Capillaries connect arteries to veins. Nutrients, oxygen, and water

use the capillary walls as a passage. These are tiny blood vessels

as thin or thinner than hair.

Veins carry blood back to your heart.

DiseasesThere are several diseases involving the circulatory system. There are

two types of circulatory system problems, viz. congenital,

problems present at birth and acquired, developed after death.

Common problems and diseases include:

Aortic aneurysm, angina, arrhythmia, atherosclerosis, high blood

pressure, and peripheral vascular disease.

Most of these diseases involve the human heart. If you do not take

care of your heart very well, you could easily get a disease

regarding it.

ConclusionIn its most basic form, the circulatory system is a simple loop which

starts, and ends, at the heart. It is also a closed system in the

sense that blood does not enter or leave the system during its

journey from the heart, to the body, and back again. In such a

system, a continuous flow of the same liquid can be pumped

through the loop again and again.

This system is yet another important part of your body- and the most

important part that keeps you alive and kicking, the heart, is a

part of it.

The circulatory system have important functions, as compared to

other parts of the body.
