Blood

The average adult male and pregnant females have 6 liters of blood, the average non pregnant female has 5 liters. Blood consists of Red Blood Cells(RBC), White Blood Cells(WBC), and Platelets. RBC’s transport oxygen atoms. The cycle of a RBC is 90-120 days. There are 5 categories of White Blood cells (WBC) aka Leukocytes: Neutrophils whose function is phagocytosis, make up 60-70% of all WBC’s, lymphocytes whose function mediate immune response make up 20-25% of all WBC’s, monocytes function is macrophage, they make up 3-8% of all WBC’s, eosinophils function is the combat the effects of histamine in allergic reactions and destroy certain parasitic worms they make up 2-4% of all WBC’s, and basophils which liberate heparin, histamine, and serotonin in allergic reactions, they make up .5-1% of all WBC’s. The WBC’s that end in -phil have granules in the cytoplasma, these granules are histamine. WBC’s that end in -cytes do not have granules. Platelets are cell fragments that live for 5-9days and they release chemicals that promote blood clotting. RBC’s and platelets do not have a nucleus, WBC’s have nucleus which may be multilobed, bilobed, round or kidney shaped.
Blood tests are used to determine how organs with in the body are functioning. Diabetes is monitored by the levels of glucose in the blood. I think of the bloodstream as a super highway in the human blood. This superhighway is transporting the gases essential to live, and it transports nutrients needed to sustain homeostasis.

Adrenal Cortex Layers

The 3 layers of the Adrenal Cortex are: zona glomerulosa, zona fasciculate, and the zona reticularis. Zona glomerulosa is the superficial layer. It primarily produces alderstone. Alderstone is a steroidal hormone that helps increase the volume of fluid in the body. The increase of fluid will increase the blood pressure. Zona fasciculate is the middle layer. It primarily produces cortisone. Cortisone is a immune suppressant. Prolonged stress will cause cortisone to increase and therefore the immune system will lower. Cortisone is non polar therefore it will not moving easily through the body. The zona reticularis is the deepest layer. It produces androgens. Androgens are steroidal hormones that aid in the development of masculine characteristics. The most well known androgen is testosterone, which is the male sex hormone. Androgens are also the precursor for estrogen, the female sex hormone. Cholesterol is the base for synthesis of these hormones produced in the adrenal cortex.
Upon researching cholesterol further to find out which foods are better for a person to consume. Animal fats have lower cholesterol and more triglycerides which may contribute to heart disease. Human breast milk has a high level of cholesterol and vegetables do not have any unless it is prepared with something that contains cholesterol. Limiting trans fats can help lower the risk of plaque build up in the walls of arteries.
