Each tissue is very good at its own job. Organs and organ systems each are specialised also. So they need to be made, of the tissue, that specialises in the job, that organ has to do.
They don't exactly have stomach divisions, rather they have chambers in one stomach. This is because of their diet, which comprises of course vegetative material that is very difficult to break down in an otherwise non-divided stomach. These different chambers offer different steps in the digestion process of grass and other forages so that the cow can squeeze out as much nurtient and energy from her diet as possible.
Analogous organs are structures in different species that have similar functions but different evolutionary origins. They have evolved independently to serve the same function in response to similar environmental pressures, rather than being inherited from a common ancestor. This is an example of convergent evolution.
Economics is not a specialized skill, rather, an area of study. One cannot economic something.
The inside of a shark contains organs such as the liver, stomach, intestines, and reproductive organs. Sharks have a cartilaginous skeleton (made of cartilage rather than bone) and powerful muscles that enable their swimming and hunting abilities. Overall, the internal structure of a shark is adapted to its predatory lifestyle in the ocean.
The stomach increases in size because the air blown by the rescuer enters the stomach rather the lungs.
Yes, endocrine glands are specialized organs that secrete hormones directly into the bloodstream, rather than into ducts or directly outside the body. These hormones then travel through the bloodstream to target organs and tissues throughout the body where they regulate various physiological functions.
I'd rather have the stomach ache. Kids last for years and years.
The word gastric refers to the stomach organ. For example, you could say "stomach juices" rather than "gastric juices" because those occur in the stomach.

The stomach primarily functions to digest food through mechanical and chemical processes, rather than absorbing nutrients. While it does absorb some water and certain mineral salts, the majority of nutrient absorption occurs in the small intestine. The stomach's primary role is to break down food and prepare it for further digestion and absorption in subsequent digestive organs.
all living organisms have organs rather they are visable or not organs ar neccesarry to from a system and that no more then what all livin organisms are a biotic system
Some animals, particularly certain types of sponges and jellyfish, primarily have specialized cells rather than true tissues or organs. For example, sponges possess unique cells called choanocytes, which help in feeding and water flow. Jellyfish have cnidocytes, specialized cells that contain stinging structures used for capturing prey. These specialized cells allow these animals to perform essential functions despite their simple body structures.
