1. The document outlines a lesson plan about the circulatory system for an 11th grade biology class. 2. The plan explains the structure and function of blood, blood components, blood groups, and disorders of the circulatory system. 3. Assessment of student learning will include observation of attitude, a knowledge test, and evaluation of group discussion and presentation.

2. 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:
55% Plasma
45% Components (sometimes called "formed elements"), i.e.
circulatory system

3. '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

4. 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
