No, because it doesn't. The planets don't orbit in weird patterns ranging from inside the sun to millions of miles from it, nor do they move in strange patterns at perpendicular angles to each other's orbits.
the structure of the circulatory system is to transport oxygen to the body
transport oxygen, nutrients, and wastes; fights infection; helps regulate body temperatureheart, veins, capillaries, arteries . what is the function of these
All of them. They all do a job that requires oxygen.
The alveoli.The Respiratory System
The lung or pulmonary system is the essential respiration organ that makes it possible for oxygen to enter the circulatory system.The alveoli struture makes it possible for oxygen to enter the circulatory system.
The alveolar region of the lungs. (alveoli)
The alveoli at the end of bronchioles allow gas exchange to occur.
Because, it kept the feaudalist protected and made sure the kings do not go over power.
The SCN (System Change Number) structure in database management systems is significant because it helps track and manage changes made to the database. It acts as a timestamp for transactions, ensuring data consistency and enabling recovery in case of system failures. This structure plays a crucial role in maintaining the integrity and reliability of the database system.
In a PERFECT System with Perfect Mirrors reflecting 100% of the Energy that strikes it....two parallel mirrors will reflect light striking it at 90 degrees to their surfaces an INFINITE number of times. Of course that System does not exist. Mirrors are NOT 100% Reflective. It is impossible to make two flat objects Perfectly Parallel, and Introducing a Perfectly Perpendicular Light Beam into the System is NOT Possible either.
Hexagonal. Trigonal Crystal System.
The respiratory system seems like the obvious answer, but you used the word absorb. The respiratory system takes air into the lungs, but the red blood cells (erythrocytes) absorb the oxygen out of the air taken into the lungs. The circulatory system then delivers these red blood cells to the capillaries where the oxygen is traded for carbon dioxide as the cells need.
