We are Hector, Irene, and Alina. 00:00:00
We are going to talk about worms and models. 00:00:04
In this video, you are going to learn about some characteristics, types, and vital functions about them. 00:00:10
General characteristics 00:00:18
Worms 00:00:20
They have bilateral symmetry, they don't have legs, they tend to live in humid climates, and they can be divided into flatworms, nematodes, and annelids. 00:00:22
Flatworms. They have a head at the front of their bodies and they are the simplest animals. 00:00:46
They have a structure called scolex that allows them to enter themselves intestinal walls. 00:01:02
They have innately cylindrical bodies. 00:01:15
Some are parasites, others live independently. They have a mouth and an anus. They feed on the hot blood or the liquids of plants and animals. 00:01:23
Anelites. They have a segmented cylindrical body. They can live in aquatic environments or terrestrial environments, and they have no circulatory system. 00:01:41
Mollusks. Generally, they have some bodies. They have lateral asymmetries. 00:02:01
The majority of them are but are some exact exceptions like snails or slugs. 00:02:11
Their bodies are made of an external layer or mantle that surrounds the internal organs. 00:02:19
They also have a shell which is a protective layer. 00:02:25
They have a complete digestive system, and many of them have an organ in their mouth 00:02:28
called radula. 00:02:45
They can be grouped in bevelers, gastropods, and cephalopods. 00:02:47
They have these valleys that are joined by hinges, they don't have heads and their organs aren't the only ones. 00:03:04
The food of this type is usually except and they use it during the 7th or 9th. 00:03:14
Gastropods. They are mainly aquatic and they have an external spiral shell and they have a defined head and has a mouth and four tentacles. Generally, they are herbivores and they have a U-shaped digestive tube due to their curved shell and have a hard and long TV system. 00:03:30
The fellow birds. Their food is next to their heads and they all have internal shells, except for octopuses. They are all aquatic. They have a well-defined head with pointed eyes next to it, divided into a set of tentacles which consume guts that help to catch prey. They are carnivores, and they have a large mouth. They have a big snake jaw to bite and make their prey. 00:03:49
Vital functions. Nutrition. 00:04:20
worms, flatworms, tapeworms. They are aterotrophs. They are aterotrophs and parasites. They have 00:04:28
some nutrients in the animal's intestine directly through their bodies. They don't 00:04:41
have a respiratory system through the mouth, it enters the food and cases go out. They 00:04:46
have a complete a community system they have an incomplete digestive system nematodes 00:04:53
Some are parasites, but others can live independently of any host. 00:05:36
The digestive system has a mouth and an anus. They feed on the whole world or on other liquids 00:05:40
in plants and animals. They have a complete digestive system, 00:05:48
no respiratory system or circulatory system. Dermatodes have a unique excretory system 00:05:51
consisting in simpler species of one or two one-celled glands, cold-brained cells, 00:05:57
and a more highly specialized form of longitudinal respiratory ducts. 00:06:03
ANALYSIS 00:06:12
They have a digestive tube with a mouth and an anus. Earthworms feed on the remains of animals 00:06:15
and plants. The majority of aquatic analysts feed on plants, and others feed on wild vertebrates. 00:06:21
The aquatic analysts reduce and others carry out cutaneous respiration, 00:06:28
Which is why terrestrial fishes need to have moist skin and they have a closed circulatory system. 00:06:34
They have a complete digestive system. 00:06:43
They have a mollusk. 00:06:54
They have a complete digestive system. 00:06:58
Many of them have an organ in their mouth, the radula. 00:07:02
A radula is a thin tongue that allows some models that scrape and grip food. 00:07:10
Aquatic models build a terrestrial space, so a cavity that works in the same way as the lungs. 00:07:19
Brothers, they don't have a head and their organs are developed. 00:07:37
They don't have a retina either because they are filter feeders. 00:07:40
They breathe through gills. 00:07:45
They have a complete digestive system and an open circulatory system. 00:07:47
The excretory system, excretory organs of bevelers are a pair of nephrivia. 00:07:53
Each of these consists of a long looped glandular tube which opens into the body cavity just beneath the head and a bladder to store the blood. 00:07:59
They have a defined category. They have a defined head that is long and tentacles. They are generally herbivores and have access to their own cells. 00:08:15
Aquatic gas supports, briefs, slugs, gills, terracots, one ear, an organ that functions as a lamp, that they have an air and open circulatory system, which distributes a liquid that contains nutrients and oxygen, degrading to their tissues. 00:08:38
They have a well-defined head with pointed eyes. 00:09:03
Next to it is a foot, which is divided into a set of tentacles, with suction cups that 00:09:14
help the animal to catch prey. 00:09:21
They are carnivores. 00:09:23
Apart from Mirabula, they have a big-shaped lobe to bite and brain their prey. 00:09:24
They breathe through yields and they have a close circulatory system. 00:09:31
Interaction. 00:09:44
Warps. 00:09:45
Bad warps. 00:09:46
They are slow-moving and some species have bright colors to warn their prey. 00:09:49
They have developed a sense of defense to deter predators. 00:09:57
Concentration nerve centers from warps. 00:10:03
They can regenerate a thin part when it is broken. 00:10:06
They have a stabilization of the nervous system. 00:10:11
Stabilization refers to the concentration of nerve centers in the front part of the animal's body. 00:10:15
Nematodes. They can interact with other nematodes, the host, and other pathogens, viruses, bacteria, and fungi. 00:10:22
Analysts. The habitat of subparasitic nematodes coupled with their sensory reduction indicates that chemical stimuli may modulate most aspects of the behavior. 00:10:43
They interact with humans when being used, or they also interact with other species. 00:11:01
It is a collection of neuronal bodies found in the voluntary and autonomic branches of 00:11:10
the peripheral nervous system composed of a pair of paired cerebral and cerebral pairs 00:11:25
of nerves. 00:11:34
It does not have a flat creeping sole but is blade-like and pointed for digging. 00:11:35
The muscles mainly responsible for movement of the foot are the interior and posterior pedal vertebrae. 00:11:41
Cephalopods. The cephalopod nervous system is the most complex of her knee invertebrates. 00:11:48
The nervous system has moving, predatory lifestyle and their complex behavior and its flexibility of response to different environmental situations. 00:11:57
Some of their main characteristics are higher brain and nervous system function. 00:12:09
Gastropods. A series of peridanglia connected by major nerve cords and a number of smaller, rich nerves using a single appending. 00:12:22
The food for many gastropods, the power of locomotion, is provided by muscular waves moving along the vertical surface of the food. 00:12:40
The probes of these webs begin to complete a substrate by deep layer of petal mollusk reproduction. 00:12:57
Flatworms. They are hemophrodites and have the cavity for cell fertilize. 00:13:18
They can do sexual or sexual reproduction. 00:13:32
Nematodes 00:13:41
They perform sexual reproduction in the eggs inside the host which are then released inside the host's excrement. 00:13:43
Other animals ingest them and the cycle continues. 00:13:51
Analytics 00:13:59
The majority perform sexual reproduction. 00:14:01
Some are hermaphrodites, but there are only one individual mixed with another to reproduce, cross-fetalization. 00:14:03
Many of them have a modified ring called the clitoris that creates a morphine substance which allows the genital pores of both parents to be together. 00:14:10
They perform models. They perform sexual reproduction by internal fertilization. They are oviparous and their development can be direct or indirect. Some species are hermaphrodite. 00:14:22
Importance of the group. 00:14:47
Worms. 00:14:52
Their feeding and boring activities incorporate organic residues and minerals into the soil, 00:14:55
In changing the composition, human formation, nutrient cycling, the soil of structural development, 00:15:03
parasitic worms have involved strategies to block parts of the human immune system. 00:15:13
And there are also main players in allergies. 00:15:19
There are 28 species of S1 in the UK. 00:15:22
Mollusks. Mollusks are among the most diverse and abundant animal groups, 00:15:26
inhabiting many active and industrial environments. 00:15:38
They are important ecosystem engineers helping to structure aquatic bottom environments 00:15:42
and providing habitat protection and puts a wide array of other taxa. 00:15:49
Molluscs are important in a variety of ways. They are used as food for decoration in jewelry and in scientific studies. 00:15:55
They are even used as rope, material, and becoming supplements. 00:16:06
Two natural products of molluscs used for decoration in jewelry are pearls and lacquer. 00:16:12
We hope you found the types of words or modules the right functions and the main characteristics. 00:16:18
If you have any questions or if you don't understand something, you can ask, remember, talk. 00:16:32
Some words are inside us and are good for ourselves. 00:16:40
