The blood has 4 main components as shown in the picture ​

​

​Some text here about the topic of discussion.

COMPONENTS OF THE BLOOD ​

The human circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, hormones, oxygen and other substances to and from cells. The heart pumps blood around the body. The blood vessels carry blood to all parts of the body. Blood is a fluid mixture that carries substances like nutrients, oxygen through the body. The circulatory system also removes unwanted substances from the body.

​MEANING

Open Ended

Name the three main parts of the circulatory sys

Fill in the Blank

------------ is responsible for pumping blood around the body

​It pumps the blood throughout the body. The heart is muscular and works wihtout tiring throughout the entire person's life. It has 4 chambers

The heart

​Act as tubes for the flow of blood. There are three types of blood vessels; Artery, veins and capillaries

​​Blood Vesssels

​The fluid that moves in blood vessels. It carries different soluble materials into and out of the body. The components include red and white blood cells, plasma and plateletes

​​Blood cells

The left-hand side pumps oxygenated blood around the body. Each side of the heart consists of an atrium and a ventricle which are two connected chambers. The atria (plural of atrium) are where the blood collects when it enters the heart. The ventricles pump the blood out of the heart to the lungs or around the body.

Left atrium​

Open Ended

In your own words, explain the movement of blood within the 4 chambers of the heart

The heart consists of four chambers in which blood flows. Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.

Movement of blood within the heart ​

Fill in the Blank

----- pumps blood from the heart to the lungs.

Fill in the Blank

------- pumps blood from the heart to the whole body.

​Teaching of the circulatory system

The left ventricle is more muscular because it pumps blood to the whole body​

Blood has 4 main components as show in the picture ​
