Blood
-
-
Clotting: Important for preventing blood loss and preventing the entry of pathogens. Vessel is damaged, chemicals go to injury site, platelets plug hole, vessel constricts (so blood doesn't go so fast), fibrinogen turns to fibrin (insoluble), scab forms
Platelets: reacts to bleeding by clumping, initiating a blood clot
Plasma: transports blood cells, proteins, ions, soluble nutrients, hormones and carbon dioxide
-
Blood Vessels
Veins: carries deoxygenated blood back to the heart (except pulmonary vein), thin but impermeable walls with valves to prevent back flow of slow, low pressure blood, wide lumen for blood
-
Arteries: A blood vessel that carries oxygenated blood away from the heart (except the pulmonary artery), thick, elastic, impermeable walls prevent bursting as blood is fast and at high pressure
Circulatory System: a system of blood vessels with a pump and valves to ensure one-way flow of blood
-
Double Circulation: E.g. mammals. Blood passes through heart twice in a circuit. Blood needs to be pumped out faster and at a higher pressure as mammals are bigger.
Lymphatic System: a collection of lymph vessels and glands, produces lymphocytes
-
Lymphatic Vessels: carry lymph, similar to circulatory system
