An organ system is a group of organs that work together as a biological system to perform one or more functions. For example, the digestive system is an organ system comprising organs like stomach, esophagus, buccal-cavity, intestine, rectum, pancreas, liver, etc. Human anatomy helps us to understand the structure and relationship of all parts of the body.
Key human organ systems: The circulatory system includes the heart, veins and arteries.
The central nervous system contains the brain and the spinal cord, while the peripheral nervous system includes nerves and ganglia that are present outside the brain and spinal cord. There are essentially two components of circulation, namely: Diagram showing pulmonary (blue) and systemic circulation (red). Anatomy is the study of the structure of an object. The presence of a well-developed digestive system helps to extract essential nutrients and minerals required by the body. Claude Bernard is the father of human Physiology.
Multicellular organisms are organised into increasingly complex parts. No, despite being incredibly tall, giraffes have the same number of vertebrae, i.e. Vertebrates like human beings possess lungs for respiration. Furthermore, most movement involves muscles that work as a pair. Anatomically, the respiratory system comprises the following organs: A diagram of the human respiratory system highlighting the gas exchange process. Animals and plants are made of cells. This is the stage at which nutrients are absorbed from the food.
The leftover materials (stool) then move on to the large intestine where it transforms from liquid to solid, as water is removed. A well developed respiratory system ensures the efficient gas exchange and the nervous system enables coordination and interaction within the body and also the external environment, thereby ensuring survival. In order, from least complex to most complex: Animal cells and plant cells can form tissues, such as muscle tissue in animals.

The spinal cord connects the brain with the rest of the body.
With respect to human body anatomy, we have a specialized circulatory system that enables the efficient transport of materials and nutrients within the body. they also have seven vertebrae in their neck. This is the result of humans having ancestors that began walking on their hind limbs rather than using all four limbs.
This swap is done through alveoli (which are the air sacs) in the lungs.
Organs are made from tissues, and systems are made from several organs working together. The abdominal cavity houses the intestines, liver and spleen.
