Phagocytosis

Cell eating, The process by which a cell engulfs foreign substances or other cells

Leucocytes

White blood cells which are produced in the bone marrow

Erythrocytes

Arteries

Carries blood away from the heart; high in oxygen

Requirements for Transportation of materials in body

Fluid to carry materials - blood; tubes/body spaces to move fluid - blood vessels; mechanism to move fluid - heart

Atrium

thin walled chamber of the heart

Ventricle

thick wall chamber of the heart

Atrium

top chamber of the heart

Ventricle

Bottom chamber of the heart

Veins

Carry blood back to the heart

Why do we need a transportation mechanism in the human body?

Large multicellular organism and all of our cells are not in contact with the outside environment; transportation mechanism is needed to carry oxygen to the cells and wastes away from the cells.

Hemoglobin

iron containing molecule found in red blood cells that carries oxygen

Homeostasis

process by which organisms maintain a relatively stable internal environment

Bicuspid Valve

Valve located on the left side of the heart between the left ventricle and left atrium

Tricuspid Valve

Valve located on the right side of the heart between the right ventricle and the right atrium

Dynamic Equillibrium

Internal environment remains the same even though the outside environment changes

Homeotherm

An organism that can keep their body temperature relatively constant

Poikilotherm

An animal who's body temperature fluctuates depending on the temperature of the animals environment

Pericardium

A tough, protective membrane that surrounds the heart

Cardiac Muscle

Makes up the wall of the heart

Septa

Thick membrane that divides the heart into two halves, the right and the left side.
