Excretory System Flashcards
the removal of the metabolic waste out of the body
Excretion
one or more contractile vacuoles are present to accumulate excess fluid and eventually discharge it outside
the cell.
amoeba
excrete by diffusing waste products from their body cells into the epidermis and out into the water.
hydra
they have Malpighian tubules that collect waste from their body fluids and discharge them into the hindgut.
insects
excrete their waste material through flame cells arranged as a branched system of ducts that are scattered
in their body cells and eventually lead to a common excretory pore.
flat worms
have segmental nephridia in each of its segment (somite) to remove waste products out of its body wall.
earthworms
two kidneys are the principal excretory organs in this organisms.
vertebrates
stomata is involved in gas exchange thereby it excretes oxygen in the environment.
plant
the process by which you get rid of toxic chemicals, excess water, salts, and carbon dioxide, maintain osmotic and pH
balance.
excretion
excrete water vapor and carbon dioxide
lungs
excess water and nitrogen waste in the form of sweat
Skins
converts ammonia to a much less toxic nitrogen waste called urea, which is then carried by the bloodstreams to
kidneys.
liver
act as body’s filter. Filtering wastes and poisons in the blood and eventually excrete them as urine. Regulate the amount of water and salts contained in the blood plasma.
kidney
made up of a complex network of tiny tube
surrounded by a tight ball of capillaries. They filter wastes from the blood, retain useful molecules and produce urine.
nephron
Filtration starts at the cup-shaped capsule of the nephron called _____________
Boman’s capsule
