Excretory System Flashcards
Its Function is for removal of harmful metabolic waste from the body also known as excretion
Excretory System
Excretory System Organs:
Small & Large Intestine
Liver
Skin
Lungs
Kidneys
Ureters
Urinary Bladder
Urethra
Examples of Metabolic Waste:
Sweat, Urine, Carbon dioxide, Nitrogen
Functions of the Excretory System:
Metabolic Waste Removal
Electrolyte Regulation
Fluid Balance
pH Regulation
Red Blood Cell Regulation
Excretory Organs of Invertebrates:
It is the Main Excretory Organ of Insects
Malphigian Tubules
Excretory Organs of Invertebrates:
It is the process where body fluid are drawn to the Malphigian Tubules
Osmosis
Excretory Organs of Invertebrates:
It contains Salt, Uric Acid, Water
Haemolymph
Excretory Organs of Invertebrates:
It is a Tubule which acts as an organ of excretion that is found in Flatworms, Ribbon worms, Rotifers
Nephridium
Excretory Organs of Invertebrates:
It is found in Platyhelminthes, Rotifers, and some Chordates that consists of Flame Cells or Solenocytes
Protonephridia
Excretory Organs of Invertebrates:
It is the exterior opening of the Protonephridia
Nephridipore
Excretory Organs of Invertebrates:
It is found on in Arthropods, Annelids, and some Mollusca, it has a ciliated funnel and don’t have Flame Cells
Metanephridia
Aquatic Invertebrate Excretion:
It lacks a distinct Excretory System, Waste products such as ammonia diffuse as water flows through the body
Porifera
Aquatic Invertebrate Excretion:
It does not have a distinct Excretory System, Waste material diffuses into the surroundings through epidermal cells
Cnidarians
Aquatic Invertebrate Excretion:
Examples of Coelenterates:
Jellyfish, Corals, Anemones
Aquatic Invertebrate Excretion:
It’s Excretory Systems main function is to remove excess water
Platyhelminthes
Aquatic Invertebrate Excretion:
Examples of Echinodermata:
Starfish, Sea Cucumber, Sea Urchins, Crinoids
Aquatic Invertebrate Excretion:
It has a primary organ for excretion, releases nitrogenous waste in a form of Ammonia through the Respiratory System
Echinodermata
Aquatic Invertebrate Excretion:
Undigested food becomes a solid waste that is removed through the anus as feces
Mollusca
Aquatic Invertebrate Excretion:
It has a complete Excretory System
Arthropoda
Vertebrate Excretion System:
It is a Kidney Structure responsible for reabsorbing water and sodium to convert it to urine
Loop of Henle
Vertebrate Excretion System:
Examples of Animals without the Loop of Henle:
Fish, Reptiles, Birds
Vertebrate Excretion System:
Classification of animals that have Small Kidneys
Reptiles
Vertebrate Excretion System:
Examples of Animals that are part of the Diapsid Group:
Snakes, Lizards, Reptiles
Vertebrate Excretion System:
Classification of Animals that does not have any Urinary Bladder, waste from both systems are combined which includes feces and urine when removed
Birds
Vertebrate Excretion System:
It is an Organ part of the bird that is used to store food
Crop
Vertebrate Excretion System:
It is an Organ part of the bird that is used for grinding food
Gizzard
Human Excretory System:
Consists of:
2 Pairs of Kidneys
2 Pairs of Ureters
Urinary Bladder
Urethra
Human Excretory System:
It Connects the Bladder to the Kidney
Ureter
Human Excretory System:
It Connects the Bladder to the Body’s Exterior
Urethra
Human Excretory System:
It is the a basic filtration unit that consists of a thin wall of blood capillaries
Kidneys
Human Excretory System:
Filtration unit packed closely together
Nephrons
Human Excretory System:
It filters the blood
Glomerulus
Human Excretory System:
It returns needed substances to your blood and removes wastes
Tubule
Human Excretory System:
It reabsorbs water, ion, and nutrients, it also removes wastes
Proximal Convoluted Tubules
Human Excretory System:
It reabsorbs water but not electrolytes
Descending Loop of Henle
Human Excretory System:
It reabsorbs electrolytes but not water
Ascending Loop of Henle
Human Excretory System:
It allows the reabsorption of water, sodium, and ions
Distal Convoluted Tubule
Human Excretory System:
It participates in fluid balance through reabsorption and secretion
Collecting Duct
