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 cardiac function
2. Describe the function of the blood vessel type
II. Learning Objectives
1. Student can explain the cardiac structure
2. Student can explain the cardiac pulse
3. Student can describe the blood vessel type
4. Student can differentiate the artery and vena
III. Learning Materials
1. Explain the cardiac structure
circulatory system
The heart and circulation of
mammals and birds. (a) The path of
blood through the four-chambered heart.
(b) The right side of the heart receives
deoxygenated blood and pumps it to the
lungs; the left side of the heart receives
oxygenated blood and pumps it to the
body. In this way, the pulmonary and systemic circulations are kept
completely separate. RA = right atrium; LA = left atrium; RV = right
ventricle; LV = left ventricle.
2. Explain the cardiac pulse
The measuring device used is called a sphygmomanometer and
measures the blood pressure of the brachial artery found on the inside
part of the arm, at the elbow. The systolic pressure is the peak pressure
during ventricular systole (contraction of the ventricle). The diastolic
pressure is the minimum pressure between heartbeats (repolarization of
the ventricles). The blood pressure is written as a ratio of systolic over
diastolic pressure, and for a healthy person in his or her twenties, a
typical blood pressure is 120/75 (measurement in mm of mercury).
3. Describe the blood vessel type
a) Arteries
Arteries function in transporting blood away from the heart. The
larger arteries contain extra elastic fibers intheir walls, allowing them to
recoil each time they receive a volume of blood pumped by the heart.
b) Venules and Veins
Blood flows from the venules to ever larger veins, and ultimately
back to the heart
4. Differentiate the artery and vena

5 minutes
Early Activities1st Phase:Presents the objectives and motivate students
Teachers present all the learning objectives
Teachers provide apperception "have you measuring the blood pressure?
Students listen to and record the learning objectives
Students answer a teacher's question by relating the events that are known from the
10 minutes
surrounding environment
2nd Phase presenting information
The teacher presents information to students about the cardiac structure
Students observe and record important information presented teachers
10 minutes
3rd phase Organize students into learning groups
The teacher showed a flash player about cardiac structure
Divide students into five groups of heterogeneous
Students attention to the video shown by the teacher
Students move with his group
25 minutes
Main Activity4th Phase:Guiding study groups and working
Teacher gives worksheets to students for discussion and presentation
Teachers guide and supervise the discussion
Students receive worksheets provided by the teacher
Students work on worksheets that teachers shared
35 minutes
5th phaseEvaluation
• Teachers refer students who will make presentations
• The teacher asks another student to provide corrections or additional explanation
Students present the results of their discussion
Students are correct or provide additional explanation
15 minutes
Closing Activities6th phase reward
• Teachers give awards to groups with the best ranking "super team"
• Teachers provide motivation to
Students who obtained a rating of super team advanced to receive award
Students listen to motivation
10 minutes
other groups• Teachers submit
material that would later be learned that the blood circulation
Students listen and record the material to be learned at home for the next meeting
