The four systems that describe the functions of the circulatory systems are:
- oxygen is delivered to cells throughout the body by this system
- This system removes carbon dioxide from organs & delivers it to the lungs.
- Carbon dioxide exits the body through this systems
- This system's organs pass oxygen into the bloodstream.

What is the circulatory system?
The circulatory system can be referred to as a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of humans or other vertebrates.
The circulatory system includes the cardiovascular system, also known as the vascular system which consists of the heart and blood vessels.

Interphase is the first phase of mitosis
Answer:
The plasma membranebeing the most necessary component of a cell because it encases and protects the complex chemistry of life within the cell. A selectively permeable membrane allows only certain substances to enter the cell. This is very important to keep necessary nutrients in and keeping unwanted substances out too
Answer:
Mesophyll and bundle sheath cell.
Explanation:
C4 pathway is also known as hatch slack pathway it is a photosynthetic process in some plants. In this pathway carbon is extracting from carbon dioxide to able to use in sugar and other biomolecules. C4 is known as four carbon molecules which is the 1st product of this type of carbon fixation.
In this pathway rubisco enzyme works in the environment where lots of carbon dioxide and very little oxygen present. CO2 is transferred via malate or aspartate from mesophyll cells to bundle sheath cells. In bundle sheath cell CO2 is released by malate decarboxylation.
C4 plants use PEP carboxylase to absorb more amount of CO2 in the mesophyll cells. Phosphophenolpyruvate (PEP) which is 3 carbon molecule binds with CO2 and make oxaloacetic acid, it forms than malate, 4carbon molecule. Malate enters through a plasmodesmata into bundle sheath cell and release the CO2.
