LESSON PLAN

School : SMA

Class/Semester : XI/1

Subject : Biology

Time Allocation : 2x45 minutes

Competency Standards : 3. Describe the structure and function of human organs and

certain animals, abnormalities / diseases that may occur as well as

the implications

Basic Competence : 3.2 Explain the relationship between structure, function, and

processes as well as disorders / diseases that may occur in the

circulatory system

I. Indicator

1. Explaining the structure and blood components

2. Describe the function of the blood in humans.

3. Describe the various blood groups in humans.

II. Learning Objectives

1. Student can explain the components of blood.

2. Student can explain the structure of blood.

3. Student can describe the function of the blood in humans.

4. Student can describe the various blood groups in humans.

III. Learning Materials

1. Student can explaining the structure of constituent components blood

Blood consists of many components (constituents).  These include:

circulatory system

55% Plasma

45% Components (sometimes called "formed elements"), i.e.

'Blood Cells'. Of these,

99% are erythrocytes (red blood cells) 

and 1% are leucocytes (white blood cells) and

thrombocytes (blood platelets)

2. The function of the blood in humans.

a. Transports

o Dissolved gases (e.g. oxygen, carbon dioxide)

o Waste products of metabolism (e.g. water, urea)

o Hormones

o Enzymes

o Nutrients (such as glucose, amino acids, micro-nutrients

(vitamins & minerals), fatty acids, glycerol)

o Plasma proteins (associated with defence, such as blood-clotting and anti-bodies)

o Blood cells (incl. white blood cells 'leucocytes', and red blood cells 'erythrocytes').

b. Maintains Body Temperature

c. Controls pH

the pH of blood must remain in the range 6.8 to 7.4, otherwise it begins to damage

cells.

d. Removes toxins from the body

the kidneys filter all of the blood in the body (approx. 8 pints), 36 times every 24

hours. Toxins removed from the blood by the kidneys leave the body in the urine. 

(Toxins also leave the body in the form of sweat.)

e. Regulation of Body Fluid Electrolytes

Excess salt is removed from the body in urine, which may contain around 10g salt

per day 

(such as in the cases of people on western diets containing more salt than the body

requires).

3. The various blood groups in humans
