Basophil
A white blood cell that releases histamine which causes inflamation
Eosinophils
Release clot digesting enzymes
Monocytes
Responsible for phagocytosis of large particles
Neutrophils
Responsible for phagocytosis of small particles
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
Red blood cells which are produced in the bone marrow
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.
