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 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

3. 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
