The cardiovascular system includes

heart

blood vessels

lymphatic vessels

The heart lies in the chest immediately behind the breastbone.

The heart consists of two chambers, left and right, separated from each other by a wall.

Each chamber is divided into upper compartment (atrium) and lower compartment (ventricle).

aorta

Valves

semilunar valves –

between ventricles and arteries

LA

the tricuspid vaive –

between the right atrium and the right ventricle

RA

LV

RV

the mitral valve –

between the left atrium and the left ventricle

The function of the valves

To prevent blood flowing the wrong way.

The circulation

The heart works as a pump. It circulates blood throughout the body.

The circulation occurs with the help

of arteries and veins.

Blood vessels

Veins

Capillaries

Arteries

thin-walled vessels

vessels returning blood to the heart

vessels carrying blood away from the heart

Blood

Functions

• Trasportation (the nutrients, oxygen are carried by the blood stream and cellular wastes are carried away by the blood stream).

2. Regulation ( supply the constant inner state and temperature of the body ).

3. Protection ( provide the immunity and the blood clotting ).

Blood is a liquid tissue containing plasma and microscopical cellular elements.

Leucocytes

45 %

Erythrocytes

Thrombocytes

(platelets)

PLASMA

55 %

Erythrocytes

Erythrocytes are red blood cells made in the bone marrow. They are important in transporting oxygen.

Hemoglobin is an important protein

which helps in carrying the oxygen and carrying away carbon dioxide.

hemoglobin

erythrocyte

4.5 – 5 million in each cubic millimeter

Leucocytes

white blood cells

T he cells of the immune system

that are involved in protecting the body .

eosinophil

monocyte

basophil

lymphocyte

neutrophil

leukocytosis

8-10 mkm

leukopenia

From 4,000 to 10,000 per cubic millimeter

12

Thrombocytes

or platelets formed in the bone marrow

These cells are necessary for blood clotting.

2 - 5 mkm

400,000 per cubic millimeter
