Unit 2 Transport systems in animal Flashcards
Blood contains
Red blood cells
White blood cells
Plasma
Blood transports
Nutrient
Oxegen
Carbondioxide
Red blood cells
Have bioconcave shape to increase surface area to hold oxegen
Nonucleus, instead contain haemoglobin
Equation
Haemoglobin + oxegen —-> oxihaemolobin
White blood cells
Part of the immune system and destroy pathogens
Types of white blood cells
Phagocytes
Phagocytosis
Phagocytes
Carry out phagocytosis by engulfing pathogens
Phagocytosis
Engulfs and digests pathogens
Lymphocytes
Produce antibodies which destroy pathogens
Antibodies
Specific to their particular pathogen
Aeorta
Carries oxygenated blood away from the heart
Artery
Carries blood away from heart
Thick muscular walls
High pressure
Thin central channel
Atria
Upper chambers oh heart
Receive blood from waves
Capillaries
Thin walled
Large surface area
Form networks around tissues and organs
Exchange of materials
Haemoglobin
Transports overgeneralise as oxyhemoglobin
Heart
Muscular organ that pumps blood around the body
Pulumanay artery
Artery carrying deoxygenated blood from heart to the lungs
Pulumanay vein
Vein carrying oxygenated blood from lungs to heart
Valve
Prevents blood of blood
Vein
Thin walled
Carry blood to the heart
Low pressures
Wide central channel
Vena cava
Vein carrying deoxiginated blood to the heart from the body system
Ventricles
Low chambers of the heart that receive blood from the atria and pump into arteries
Why is the the muscular wall of the left ventricle thicker than the right
Left has to pump blood to the whole body
Right has to only pump to the lungs
Difference between lacteals and capillaries
Capillaries absorb glucose and amino acids
Lacteals absorb fatty acids and glycerol
