What is the simplest level of organization in the body?

The human body has many levels of structural organization: atoms, cells, tissues, organs, and organ system. The simplest level is the chemical level, which includes tiny building blocks such as atoms. Cells are the smallest functional units of life. Tissues are groups of similar cells that have a common function.

organismal level

What are the five levels of organization in our bodies from smallest to largest?

It is convenient to consider the structures of the body in terms of fundamental levels of organization that increase in complexity, such as (from smallest to largest): chemicals, cells, tissues, organs, organ systems, and an organism. Figure 1.2.

What level of organization would a dolphin represent?

The 4th level of organization, organ systems are made up of two or more organs and the system provides a basic function for the organism. Dolphins have a outer layer of skin called the epidermis and it is 10 to 20 times thicker then humans.

  • Gluten Sensitivity and Celiac Disease.
  • Inflammatory Bowel Disease (IBD)
  • Irritable Bowel Syndrome (IBS)
  • Constipation.
  • Hemorrhoids.

What systems is the digestive system connected to?

(1) Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go. (2) Filters out waste from food and pushes it through intestines and out the body (and you know how and where it gets out).

How does the muscular system work with the digestive system?

The muscular system allows for movement within the body, for example, during digestion or urination. Smooth muscles in the gastrointestinal or GI tract control digestion. The GI tract stretches from the mouth to the anus. Food moves through the digestive system with a wave-like motion called peristalsis.

How do the digestive and urinary systems work together?

Kidneys, part of the urinary system, remove all types of cellular waste products from your blood. Your digestive system eliminates feces from your body.
