What body systems evolved by piggybacking on the respiratory circulatory or digestive systems?
The immune system evolved by piggybacking on the circulatory system, as immune cells circulate throughout the body via the blood. The lymphatic system also utilizes the circulatory system to transport lymph fluid and immune cells. Additionally, the endocrine system often influences digestive system functions by releasing hormones that regulate digestion and nutrient absorption.

Is every living thing's respiratory system the same as ours?
No, not all living things have a respiratory system like humans. Different organisms have evolved various methods to exchange gases with their environment, such as through gills, spiracles, or direct diffusion through the skin.
how has the body evolved to avoid ingesting toxins?
The body has evolved to avoid ingesting toxins by developing mechanisms such as taste aversion, which causes a dislike for foods with potential toxins, and by increasing the sensitivity of the digestive system to detect and expel harmful substances. Additionally, the liver plays a crucial role in detoxifying ingested toxins by metabolizing and eliminating them from the body.
What is the correct interpretation of the cladogram shown below?
Koalas evolved after trout
Why do most animals have the same kinds of organ systems?
Most animals have similar organ systems because they have common evolutionary ancestors. Over time, these ancestors developed specialized organs to carry out different functions in order to adapt to their environments. As a result, many animals share similar organ systems, such as digestive, circulatory, and respiratory systems.
Why has hemispheric specialization evolved?
Hemispheric specialization is thought to have evolved to enhance cognitive efficiency and optimize processing of different types of information. The specialization allows for tasks to be divided between the two hemispheres, enabling faster and more effective processing. Additionally, it may have evolved as a way to increase cognitive capacity and adaptability in response to environmental demands.
Does a snake have an open circulatory system?
no they dont. They have a closed circulatory system because they are so long.
Why were changed in the respiratory and circulatory systems so important to vertebrate evolution?
they improved oxygenation of tissues
How come we don't gets scoushed by air pressure?
We don't get squished by air pressure because our bodies are also filled with air, so the pressure inside and outside our bodies remains balanced. Our bodies have evolved to withstand the external air pressure, and any small changes in pressure are easily managed by our respiratory and circulatory systems.
What would happen if humans evolved without blood?
Humans are primates. Long before any species of primate evolved a replacement for the mammalian circulatory system, they would probably no longer be considered mammals. Actually, virtually all vertebrates possess a similar circulatory system. I think some invertebrates may get along without blood.
What would have happened if humans had not developed a circulatory system?
Humans didn't develop a circulatory system. Early forms of circulatory systems developed in the first animals and organisms to roam the earth. As these species evolved through speciation and genetic variation, new species came to exist that also had circulatory systems. Over time, the systems became more complex and efficient (compare the cardiopulmonary circulatory system of the human compared to the circulation of a fish). Therefore, without circulatory systems there would be no humans nor would there be life as we know it
Are small amounts of carbohydrates needed for good health?
It is better with large amounts of carbohydrates. That is what our digestive system has evolved to digest. Complex carbohydrates and not simple sugars.
Is every living thing's respiratory system the same as ours?
No, not all living things have a respiratory system like humans. Different organisms have evolved various methods to exchange gases with their environment, such as through gills, spiracles, or direct diffusion through the skin.
How does a fluke protect itself from the digestive enzymes of its hosts?
Flukes have a protective covering called a tegument that helps them evade the digestive enzymes of their hosts. The tegument acts as a barrier, preventing the enzymes from reaching the fluke's body. Additionally, some flukes have evolved mechanisms to neutralize or resist the effects of digestive enzymes.
What does a cat's anatomy look like?
A cat has the same muscles, organs and basic bone structure like most other animals: Cats have short limbs and strong muscles for pouncing and sprinting, the circulatory and digestive system works just like other mammals', although a cat's intestinal tract is shorter than omnivores and herbivores as a cat has evolved to be very efficient at digesting meat.

What are the differences between the internal anatomy of a bird and human?
Birds have evolved to be lightweight for flight, so their bones are hollow and some organs are reduced in size. They also have a unique respiratory system with air sacs that facilitate efficient gas exchange. Additionally, birds lack a diaphragm and have a crop for storing food before digestion. Humans have a diaphragm and solid bones that support weight-bearing and movement. Our respiratory system consists of lungs with alveoli for gas exchange. Humans have a longer digestive tract with a well-developed stomach and intestines for processing food efficiently.
Why are red blood cells built to carry oxygen?
Something has to do this job, so if it wasn't red blood cells then it'd need to be something else. Unless, of course, mammals had evolved in some other way which did not have a circulatory system.
Two basic types of circulatory systems that have evolved over time?
open and closed circulatory systems.open system: the blood leaves the discrete vessels and bathes at least some non-vascular tissues directly. (crustaceans, mollusks, arthropods, etc.)closed system: there is always at least a thin vessel wall separating the blood from the other tissues. (mammals,birds, etc.)
