Do humans have a gastrovascular cavity?
No, humans do not have a gastrovascular cavity. Instead, they have a more complex digestive system that includes organs such as the stomach, small intestine, and large intestine for processing food and absorbing nutrients.
What happens when the size of body of organism increases and the body design becomes more complex?
Because the more complex an organism become the more surface area to volume ratio.This means that unlike simple organism(like insects) who rely on diffusion for transport of oxygen and nutrients is readily available due to their excellent surface area to volume ratio. However if an organism has a bad surface area to volume ratio(larger organisms) they require a more efficient flow of oxygen and nutrients throughout their body.
Why does the digestif system have more organs?
The digestive system has more organs because it is responsible for breaking down food, extracting nutrients, and eliminating waste from the body. Each organ performs specific roles such as digestion (mouth, stomach, small intestine) and absorption of nutrients (small intestine), which requires a complex network of organs working together.
Is an Impala a ruminant animal?
Yes, an Impala is a ruminant animal. Ruminants are animals that have a complex stomach with four compartments, including cattle, sheep, and deer. Impalas have a similar digestive system that allows them to efficiently digest and extract nutrients from plant material.
Is gastrovascular cavity of dugesia a simple sac?
No, the gastrovascular cavity of Dugesia is not a simple sac. It is a more complex structure that serves both as a digestive chamber and a circulatory system. This cavity has branches that allow for the distribution of nutrients and removal of waste throughout the organism.
Why dont most parasitic flatworms need a complex digestive system?
Parasitic flatowms typically live in the digestive system. Surrounded by pre-digested nutrients, they can easily absorb basic nutrients that they need to maintain homeostasis. In other words, they are borrowing the host's digestive system.
Do all living things need a digestive system?
No, not all living things need a digestive system. For example, some simple organisms like bacteria absorb nutrients directly through their cell membrane. However, for complex multicellular organisms, a digestive system is necessary to break down food into nutrients that can be absorbed and utilized by the body.
What kind of digestive system do earthworms have simple or complex?
I am pretty sure they have simple but very complex digestive systems
Do food that passes through the digestive tract becomes less complex?
Yes. It is broken down into its comprising proteins, starches, carbohydrates, minerals, vitamins, etc...
What does complex nutrients mean?
Complex nutrients are a type of sustinance that contain a high nutritional value and are often difficult to breakdown than simple nutrients. Complex nutrients are often found in foods such as whole grains and vegetables.
Does a jellyfish have a simple or complex digestive system?
Jellyfish have a simple digestive system. They have a digestive cavity with cells lining the wall that carry out the digestive function.
Do humans have a gastrovascular cavity?
No, humans do not have a gastrovascular cavity. Instead, they have a more complex digestive system that includes organs such as the stomach, small intestine, and large intestine for processing food and absorbing nutrients.
What are the simplest digestive compartments.'?
The simplest digestive compartments are the gastrovascular cavities and the alimentary canals. Gastrovascular cavities, found in organisms like jellyfish and flatworms, serve both digestion and distribution of nutrients, having a single opening for both ingestion and egestion. Alimentary canals, seen in more complex organisms, consist of a one-way digestive tract with separate openings for ingestion and egestion, allowing for more efficient digestion and absorption of nutrients.
In the digestive process complex foods are broken down into simpler substances like what?
in the digestive process, complex foods are broken down into simpler substances like what?
What does nutrients mean?
Complex nutrients are a type of sustinance that contain a high nutritional value and are often difficult to breakdown than simple nutrients. Complex nutrients are often found in foods such as whole grains and vegetables.
what is human digestive system?
The human digestive system is a complex network of organs designed to break down food and liquids into nutrients that the body can absorb. These nutrients are vital for energy, growth, and cell repair. The digestive system works continuously to ensure that food is processed efficiently, supporting overall health. Digestion plays a crucial role in maintaining the body’s balance, as it transforms food into a form that cells can use. This system showcases incredible complexity and efficiency, handling various tasks seamlessly, from breaking down food mechanically to absorbing nutrients into the bloodstream.
Decomposers play an important role in which matter cycle?
cycling of mattter is the amounts of nutrients available on Earth, it is to be recycled in order to ensure the extistance of biotics. After a plant or an animal dies, it leaves nutrients behind which is mixed with soil and becomes a part of the biosphere. The nutrients in the soil mixed with gases(o2...)is called nitrogen cycle.
