Your body cells use oxygen you breath to get energy from the foods you eat. The process is called "Cellular Respiration." This process or function consists of the cell using oxygen to break down sugars in the body. When the cell uses the oxygen to break down sugars, carbon-dioxide is produced and energy is released, thus producing the energy your body needs.
"Hemoglobin" is a protein with Red Blood cells (also referred to as RBC's) that are responsible for the transport of oxygen. The Cardiovascular System consists of the heart and vessels and may also be referred to as the vascular system or the circulatory system. The heart functions as a muscular pump that pushes blood through the vessels to all areas of the body and the vessels function to carry it back to the heart as well. Hence the name "circulatory."

LAMARCK's THEORY
Jean Baptiste Lamarck (1744-1829) proposed a theory which was published in "<em>Philosophie Zoologique"</em> (1809). This theory is simply known as Lamarckism. It has two main postulates:
1. Use and disuse of organs
2. Inheritance of acquired characters.
Example
He explained his theory by giving the examples:
1. Neck length of Girrafes
2. Webbed toes of water birds, and
3. Wings of penguins
Explanation
Lamarck explained that water birds use toe for swimming, with the passage of time webbed were developed in their toes. these features were then transferred to their offspring.
Drawback
Lamarck theory was based on natural observation. It did not explain the genetic basis of such characteristics.

Explanation:
Golgi apparatus is an organelle in eukaryotic cells that stores and modifies (might include addition of sugar groups) proteins and lipids for certain functions and prepare them for transport to other parts of the cell.
In the Endoplasmic reticulum, proteins fold into into their correct shape. Some of them are transported to the Golgi apparatus in membrane vesicles. Some proteins need to do their jobs in the Golgi (they are said to be Golgi-resident). They are transported from the golgi appratus to their final destinations through a secretory pathway. It involves sorting proteins into different kinds of transport vesicles, which emanate from the trans Golgi network and deliver their contents to the appropriate cellular locations.
Proteins that are membrane embedded are conveyed to the plasma membrane (integral membrane proteins) by constitutive secretion. Proteins can divert from constitutive secretion pathway and be targeted towards other destinations such as lysosomes (as lysosomal proteins) and regulated secretion from cells (to the cell exterior).
