This lesson plan outlines a biology lesson on the circulatory system. The objectives are for students to: 1) Explain blood circulation in vertebrates and invertebrates, 2) Describe circulatory diseases, 3) Describe blood diseases, 4) Describe blood vessel diseases, and 5) Describe cardiac diseases. The lesson will involve presenting information, showing a video, dividing students into groups to discuss worksheets, and group presentations. Students will be assessed on their attitude through observation and on their knowledge through tests.

3. 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

4. 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

5. 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.
