grade topic of the lesson

00:00:06

excretion in the process of vital activity of

00:00:09

the body, both plant and

00:00:12

animal, substances are formed that are

00:00:15

not needed for it and sometimes even dangerous

00:00:18

this is the so-called waste it can be

00:00:22

water carbon dioxide ammonia urea and

00:00:25

many other compounds

00:00:28

therefore before each the body faces

00:00:31

the problem of removing these substances,

00:00:34

it is solved differently; in protozoa, metabolic products

00:00:38

leave the cell through the cell

00:00:40

membrane into the environment where their

00:00:44

concentrations are much lower, but it is

00:00:47

more difficult for them to get rid of excess water;

00:00:51

freshwater protozoa are freed from

00:00:54

it with the help of contractile vacuoles, a

00:00:57

small vesicle lying in the cytoplasm,

00:01:00

periodically contracting, it pushes the

00:01:04

liquid in it

00:01:05

out; in most multicellular

00:01:09

animals, various

00:01:10

special adaptations appear;

00:01:12

for example, in flatworms, this system of

00:01:15

excretory tubules, which

00:01:18

originate from special so-called

00:01:21

ciliated cells with a bunch of

00:01:24

constantly oscillating cilia, they

00:01:27

absorb the liquid surrounding them with

00:01:30

harmful products metabolism and

00:01:32

direct it into the canaliculus and which

00:01:35

carry it through the excretory sometimes

00:01:38

outward in the earthworm, excretion is

00:01:42

carried out through ne fride, a

00:01:44

diminutive of the Greek not phrases. the

00:01:48

tubules that open from the cilia into

00:01:51

funnels into the body cavity;

00:01:54

unnecessary substances are collected in them and removed

00:01:57

through excretory pores; the tubules are

00:02:01

surrounded by numerous capillaries

00:02:03

through the walls of which metabolic products are removed

00:02:06

from the blood; the

00:02:09

excretory system of insects

00:02:12

is represented by such long

00:02:14

tubes, one end of which lies in the

00:02:17

body cavity and the other opens into the

00:02:20

hind intestine and the lymph circuit

00:02:23

fills the body cavity of the insect

00:02:26

excretory tubes through their walls,

00:02:29

metabolic products enter the intestines,

00:02:31

then they move into the intestines in

00:02:35

the intestines water is absorbed into the lymph

00:02:37

and dry substances are released out the

00:02:41

main excretory organ of vertebrates, the

00:02:44

kidneys, through which liquids unnecessary for

00:02:48

the body are removed substances in fish, for example,

00:02:51

kidneys look like 2 elongated ribbons of prominent

00:02:55

organs located under the spine of the

00:02:58

upper part of the body cavity in

00:03:01

mammals, blood passing through a

00:03:04

capillary network that penetrates the

00:03:06

kidneys releases metabolic products dissolved in it,

00:03:09

two ureters depart from the kidneys,

00:03:13

along which the resulting urine is collected in the

00:03:17

bladder and then through a special

00:03:19

hole it comes out in the process of

00:03:23

excretion, other organs also take part,

00:03:26

so carbon dioxide is released in

00:03:30

animals through the skin gills lungs water

00:03:34

through the skin and lungs and mineral salts

00:03:38

some organic substances

00:03:40

are excreted through the skin intestines and

00:03:43

special devices

00:03:45

some animals have special cells in

00:03:49

which products accumulate exchange

00:03:51

these are accumulation buds in

00:03:56

plants and fungi there is no special

00:03:59

excretory system, many substances that are not necessary

00:04:01

for them are deposited in the cells of

00:04:05

multicellular containers and

00:04:07

are stored throughout their life

00:04:10

from many harmful substances the plant is

00:04:13

released during leaf fall

00:04:15

listening to the outer layers of the bark the crusts of

00:04:19

some plants from excess water and

00:04:22

salts are released through special

00:04:25

groups of cells water

00:04:29

stomata or hyda todas, usually they

00:04:32

are located at the top

00:04:35

and along the edges of the leaf the

00:04:37

droplets they secrete can be seen

00:04:40

on the leaves in the morning in hot weather

00:04:44

defoliation is the natural separation of

00:04:47

leaves from the stem,

00:04:50

unnecessary and even harmful substances accumulate in the leaves

00:04:53

they are removed from the plant during the process of

00:04:56

shedding leaves, and the necessary substances

00:04:59

swell to other organs where they are used

00:05:03

or accumulated in storage tissues

00:05:06

before leaf fall, the leaves lose their green

00:05:09

color as chlorophyll is destroyed and

00:05:13

other coloring substances become visible,

00:05:16

pigments of yellow, red and orange, which is

00:05:19

why trees and

00:05:23

shrubs turn crimson in autumn golden

00:05:26

in the kidneys, urine is formed from

00:05:31

substances brought by the blood; the

00:05:34

structure of the kidney is based on the nephron from the

00:05:37

Greek phrase.

00:05:39

its main structural element,

00:05:41

the formation of urine is divided into two stages,

00:05:44

the first is

00:05:46

filtration, as a result of which primary urine

00:05:49

is formed from substances brought by the blood,

00:05:51

then from it

00:05:55

water and

00:05:57

some substances valuable for the body are reabsorbed into the blood;

00:06:00

this is the second stage, the formation of a secondary

00:06:03

matcha which is removed from the body,

00:06:08

let's remember During the process of

00:06:10

life,

00:06:13

unnecessary and harmful substances are formed in the body that

00:06:16

need to be removed from it. In animals,

00:06:19

these functions are performed by the excretory

00:06:22

system. The main organ of excretion in

00:06:25

vertebrates

00:06:26

is the kidneys; plants and fungi do not have

00:06:30

special excretory systems.
