Is a fibromuscular wall made up of collagen, fibers, and muscles. It is found between the right and left chambers of the heart.

Destroy bacteria through phagocytosis.

Is made up of 7% proteins and about 1% inorganic salts, and some other organic substances.

A pear-shaped highly muscular organ that is responsible for blood circulation. It pumps blood to all parts of the body, and in return receives blood coming from the different parts of the body. It can be found in the thoracic cavity and covered by a membrane called pericardium.

Are Leukocytes without granular cytoplasm.

Receives deoxygenated ( oxygen-poor ) blood from all parts of the body through the superior and inferior vena cava.

Pump blood to all parts of the body, thus their muscular walls are thicker.

Pumps deoxygenated blood to the lungs through the pulmonary artery.

What are the 4 Chambers of the heart?

Are the most abundant blood cell formed in the red bone marrow of the bones. It can be easily identified with its biconcave shape.

Are larger than red blood cells but fewer in number. They are produced in the bone marrow, while some are in the spleen, and lymph nodes.

what is this picture?

Are conducting tubes that carry blood from the heart to the different parts of the body, and vice versa.

These are blood vessels that can reach the cells of the different organs.

Regulate inflammation.

What is this picture?

Pumps oxygenated blood to all parts of tire body through the aorta.

Receives oxygenated ( oxygen-rich ) blood from the lungs through the pulmonary veins.
