What is the humoral coagulation system?

User Avatar

Asked by Aiguy

The humoral coagulation system prevents excessive bleeding by initiating a cascade of reactions. It involves vasoconstriction, platelet adhesion for primary hemostasis, and a cascade of enzymatic reactions leading to fibrin formation during secondary hemostasis. This reinforces the platelet plug, creating a stable blood clot.

The system is finely regulated to balance clotting and prevent excessive bleeding. Disorders can lead to bleeding or thrombotic issues, necessitating medications like anticoagulants for therapeutic intervention.

This was short explanations of humoral coagulation system.

Also, to learn more and understand this topic in detail or any other topics of this Subject, I would suggest this online course - Medicine for UnderGrads by Dr Archith Boloor available on the DigiNerve app.

It includes video lectures, notes and self-assessment questions covering all the important topics and concepts of medicine subject.

This course helps a lot in building concepts through case-based learning. And also, all this is available at an affordable price.

What is one similarity between the respiratory and circulatory and digestive systems?

User Avatar

Asked by Wiki User

Both have a high surface area for exchange: In the respiratory system the exchange of oxygen an carbon dioxide takes place between the alveoli and blood capillaries (both provide a high surface area for exchange) and in the digestive system, exchange of nutrients and waste takes place between the villi and blood capillaries (also both provide a high surface area for exchange)

In both systems, transported materials pass through the membranes by a process called diffusion.

Why do humans need transport system?

User Avatar

Asked by Wiki User

We need nutrients and oxygen to be supplied to our cells at a very fast rate as our cells need a lot of energy to keep us alive. Therefore we must have an efficient transport system to transport nutrients and oxygen to the billions of cells in our body. The transport system in man is known as the circulatory system.

Why is the interaction a frogs digestive and circulatory system important for its survival?

User Avatar

Asked by Wiki User

Well.... The frog needs nutrients in order to survive. When the frog would eat its food, the food would go down through the digestive system, where obviously the food would break down. Then the circulatory system would take the broken down food and spread the nutrients that were taken from the food, all across the frogs body.

So the main answer is that a frogs digestive and circulatory system are important for its survival because the frog needs nutrient given to its body. The two systems work together to break down the food and spread the nutrients across the frogs body.

- This was the way I answered a question on my lab.

Explain Why the human circulatory system is said to show double circulation?

User Avatar

Asked by Wiki User

In double circulation there is complete segregation of oxygenated and deoxygenated blood. Because of this the blood passes twice through the heart in one cycle of circulation hence the name double circulation. This is necessary for optimum oxygen utilization as humans are warm blooded animals and need extra energy to maintain their body temperature

Depends how big you want it. It might be worth getting hold of a red plastic inflatable ball, let some air out and push the edges in, then seal it up again. It might be too floppy though - just an idea...

What does Rub-a-dub-dub three men in a tub mean?

User Avatar

Asked by Wiki User

Most nursery rhymes have adult origins - reading a nursery rhyme and trying to understand the literal meaning of the words is nonsense.

"Hey rub a dub dub

Three men in a tub

The brewer, the baker, the candlestick-maker

They all sprung out of a rotten potato

An apple for the king

A pear for the queen

And a good toss over the bowling green

The bowling green it was so high

It nearly tossed me over the sky

Sky, sky, let the cat die."

from Norman Iles book "Restored Nursery Rhymes"
