Lesson 7: Organ Systems Coordination
1. Organisms exhibit complex properties due to interactions between their constituent parts
a. Interactions and coordination between organs provide essential biological activities
The kidney and bladder work together in the excretory system in order to filter the blood. The purpose of the kidney is to filter the blood and the blood will flow into the glomerulus which is seen as a dead end and a build up of a urine. This is where the ladder comes in - the bladder is able to hold the urine until it is ready to be released from the body. So the kidney and the bladder are working together for a common goal of cleaning the blood and removing waste from the body.
b. Interactions and coordination between systems provide essential biological activities
In the respiratory system, the alveoli in the lungs allows for the oxygen to remove from high to low concentration while carbon dioxide is leaving the oxygen. The respiratory system will then pass the oxygen to the circulatory system which will move the oxygen throughout the heart and other parts of the body - a function that the respiration function would not be able to do on its own because the oxygen would not be able to travel far from the lungs. The oxygen sticks to the hemoglobin in the blood cells to transfer to other parts of the body while carbon dioxide goes in opposite direction to leave the body.
2. Cooperative interactions within organism promote efficiency in the use of energy and matter
a. Organisms have area of compartments that perform a subset of functions related to energy and matter, and these parts contribute to the whole
The specialization of organisms start at a molecular level. Specialized cells will form tissues that will have a certain function for an organ. For example, the pancreas has important enzymes that are critical to the digestive system and regulating sugar level for the endocrine system. When looking at the digestive system, every organism have a certain role in the digestive process. The stomach is responsible for the breakdown of food to get proteins out of it and then producing digestive juices. The different cells in the stomach each help to make this process occur - one type of cell will secrete the protein digesting enzymes, one cell type will produce mucus, another will protect the stomach lining, etc.
