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

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
