When any injuries or cut in our body, Name the fluid which wose out immediately?
List our Some of thedonations from our body?
EVALUATION
SPECIFICATIONS
Recognizes
CONTENT
The Human heart plays vital role in our circulatory system
LEARNING EXPERIENCE
EVALUATION
In which part of the body the circulatory system takes place?
SPECIFICATIONS
Identify
CONTENT
The Circulatory system is made up of the hear,blood and blood Vessels
LEARNING EXPERIENCE
The pupil identified the circulaory system.
EVALUATION
What do you know about the circulatory system?
SPECIFICATIONS
Defines
CONTENT
The space between the pericardial membrane is called Pericardial space
which is filled with fluid called Pericardial fluid.
This pericardial fluid protects the heart from shock. The heart is placed
inside the throacic chamber in between two lungs.
LEARNING EXPERIENCE
Students understood about the Pericardial fluid.
EVALUATION
Define Pericardial fluid
SPECIFICATIONS
Explains
CONTENT
The heart is a hollow, muscular organ. It is some what conical in shape.
The heart is covered with double walled membrane called Pericardium.
LEARNING EXPERIENCE
Teacher explain the structure of heart
EVALUATION
Name the double walled memberance that covers heart.
SPECIFICATIONS
Describes
CONTENT
The heart is four chambered musculart organs that pumps blood.
The two upper chambers are called artria and two lower thicker chambers
are called Ventricles
LEARNING EXPERIENCE
Student understood about the chambers of the heart
EVALUATION
What is the name of the two upper chambers of the heart?
SPECIFICATIONS
Classifies
CONTENT
Blood Circulation
Pulmonary circulation loop
Systematic circulation loop
LEARNING EXPERIENCE
Student classifies the types of blood circulation
EVALUATION
Classify the Blood circulation?
SPECIFICATIONS
List Outs
CONTENT
The blood corpuscles are of three types.
1. Erythrocytes or Red blood corpuscles (RBC)
2. Leucocytes or White blood corpuscles (WBC)
3. Thrombocytes or Blood Platelets
LEARNING EXPERIENCE
Pupil learn the 3 types of blood corpuscles.
EVALUATION
List out the three types of blood corpuscles.
SPECIFICATIONS
List Outs
CONTENT
 Blood carries the metabolic waste to the excretory organs
 Blood distributes the digested food
 Blood carries hormones which are secretions of endocrine grands.
 Blood distributes the heart evenly throughout the body.
 Blood keeps all the tissues moist
LEARNING EXPERIENCE
Teacher explain the functions of blood
EVALUATION
State any two functions of blood
SPECIFICATIONS


Arteries
It carries blood from the heart to the
organs
It carries oxygenated blood except
pulmonary artery
The wall is thick and elastic
It is found deep inside the muscles
Valves are absent





Veins
It carries blood from the organs to the
heart
It carries deoxygenated blood except
pulmonary veins
The wall is thin and elastic
It is found superficially
Valves are present
LEARNING EXPERIENCE
Teacher shows the chart of difference between arteries ad veins to the
students
EVALUATION
State the difference between arteries and veins
