III. Learning Materials

1. The blood circulation in animals vertebrate

a) Fish

The fish heart is a modified tube, consisting of a series of four

chambers. Blood first enters the heart at the sinus venosus, where

the wavelike contraction of the heart begins.

b) Amphibian

The heart and circulation of an

amphibian. The frog heart has two

atria but only one ventricle, which

pumps blood both to the lungs and to

the body.Despite the potential for

mixing, the oxygenated and

deoxygenated bloods (red and blue, respectively) mix very little as

they are pumped to the body and lungs. The slight mixing is shown

in purple. RA = right atrium; LA = left atrium; V = ventricle

c) Reptile

reptiles, additional modifications have reduced the mixing of blood

in the heart still further. In addition to having two separate atria,

reptiles have a septum that partially subdivides the ventricle. This

results in an even greater separation of oxygenated and

deoxygenated blood within the heart.

d) Mammalian and bird

Mammals, birds, and crocodiles have a four-chambered

heart with two separate atria and two separate ventricles The right

atrium receives deoxygenated blood from the body and delivers it

to the right ventricle, which pumps the blood to the lungs. The left

atrium receives oxygenated blood from the lungs and delivers it to

the left ventricle, which pumps the oxygenated blood t the rest of

the body. This completely double circulation is powered by a two-

cycle pump.

2. The blood circulation in animals invertebrate

Circulatory systems of the animal kingdom. (a) The

gastrovascular cavity of Planaria serves as both a digestive and

circulatory system, delivering nutrients directly to the tissue cells by

diffusion from the digestive cavity. (b) In the open circulation of an

insect, hemolymph is pumped from a tubular heart into cavities in the

insect’s body; the hemolymph then returns to the blood vessels so that it

can be recirculated. (c) In the closed circulation of the earthworm,

blood pumped from the hearts remains within a system of vessels that

returns it to the hearts.

3. Blood disease

a) Hemophilia is caused by insufficient clotting proteins in the blood.

As a result, a person with hemophilia bleeds for a long time and is

at risk of dying from internal bleeding that may occur as a result of

a minor injury.

b) Anemia is a fairly common blood disorder in which the blood

contains fewer than normal healthy red blood cells

c) Leukemia is a cancer of the white blood cells. There are two main

types of leukemia: myeloid and lymphoid

4. Blood vessel disease

a) Strokes are caused by an interference with the blood supply to the

brain. They may occur when a blood vessel

b) Atherosclerosis is an accumulation within the arteries of fatty

materials, abnormal amounts of smooth muscle, deposits of

cholesterol or fibrin, or various kinds of cellular debris.

c) Arteriosclerosis, or hardening of the arteries, occurs when calcium

is deposited in arterial walls. It tends to occur when atherosclerosis

is severe.

5. Cardiac disease

a) Cardiovascular Diseases, Heart attacks may be caused by a blood

clot forming somewhere in the coronary arteries (the arteries that

supply the heart muscle with blood) and blocking the passage of

blood through those vessels.

b) Aneurysm, Arteries have thick walls that allow them to withstand

pressure.

Early Activities

1st Phase:Presents the objectives and motivate students

Teachers present all the learning objectives

Teachers provide apperception "did you ever hear about anemia?" What you see

Students listen to and record the learning objectives

Students answer a teacher's question by relating the events that are known from the surrounding environment

10 minutes

2nd Phase presenting information

The teacher presents information to students about the circulation disorder

Students observe and record important information presented teachers

3rd phase Organize students into learning groups

The teacher showed a flash player about atherosclerosis

Divide students into five groups of heterogeneous

Students attention to the video shown by the teacher

Students move with his group

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
