Hemolytic Disease

When the fetus is Rh+ and the mother is Rh-, then mom has'nt any antibodies for the Rh+. Exposing the RH+ from the babies blood to the mother's her body will start to produce Rh+ antibodies. We don't want mom to start producing the RH+ for any length of time so mom is given a synthetic drug called the Rhogam shot. The Rhogam shot prevents the spread of Rh+ antibodies. Being Rh- you don't have any Rh antibodies unless you've been exposed to Rh+ blood and this is when you would produce Rh antibodies. A child is Rh+ and the mother is Rh- and has already been exposed and not treated, the mother is producing Rh antibodies which can lead to hemolytic disease!!!! (Newborns) Here red blood cells break open and release hemoglobin into the surrounding fluid (plasma).

My brothers wife malissa had to have the Rhogam shot. I spoke with her recently on the phone and learned that her son bryce was RH+ and she would have started to produce RH+ antibodies which in turn could have lead to hemolytic disease!!! Though she told me its not as common on your first pregnancy she still had to watch out for pale coloring due to anemia after birth. The primary doc. did have her come in to check Bryce's liver and spleen to see if they were enlarged. This was done by a ultra sound she said.

fetal circ.

Blood leaves the placenta through a cord which is composed of two two arteries and one vein. H2O is supplied by the vein to the baby. Blood enters the baby through the cord below the liver, then (blood) enters the liver where it's cleansed, filtered and moved to the heart, where it enters at the R. atrium. Starting at the right atrium there are two pathways that the blood can take. 1st, Right atrium to the L. atrium through the interatrial septum which is located at the foramen ovale. Then from here it enters into the left ventricles and through the lungs. 2nd, blood enters the R. atrium to the R. ventricle to the pulmonary SL valve to the pulmonary trunk to the pulmonary artery to the Right and left lungs. At the pulmonary artery it overlaps the aortic arch which here a hole that allows blood to enter and then circulated to the rest of the body.

The mother of my son Kamren had to have a c-section due to low H2O levels. Unfurtunately Kamren has suffered some brain damage. The doctors related his condition to the lack of oxygen supplied by the vein to him. What I've learned has helped me understand that as a baby not getting oxygen can have life long complications so going to the doctors for scheduled checkups is crucial. To this day Kamren is currently dissabled because of his motor skills and he suffers from other complications due to the lack of H2O.

sex organs

In addition to producing gametes, the female ovaries and male testes also secrete hormones. These hormones are called sex hormones. The secretion of sex hormones by the gonads is controlled by pituitary gland hormones such as FSH and LH. While both sexes make some of each of the hormones, typically male testes secrete primarily androgen's including testosterone.

Later in life Men have a decrease in testosterone and may need supplements or a combination of eating right and going to the gym regularly. I find that for me running three miles a week and eating healthy gives me more of a sex drive. I recommend not taking steroidal hormones that aren't FDA approved because long term effects are not known.

Pancreas

This organ has two functions. It serves as a ducted gland, secreting digestive enzymes into the small intestine. The pancreas also serves as a ductless gland in that the islets of Langerhans secrete insulin and glucagon to regulate the blood sugar level. The islet cells secrete glucagon, which tells the liver to take carbohydrate out of storage to raise a low blood sugar level.
I have been tested once for diabetes and my doctor had to put me on a better diet then I was on. The doctor originally though my body wasn't producing enough insulin which would cause diabetes. So lucky for me I don't have diabetes because I exercise often and eat healthier.

Thyroid hormones regulate metabolism, therefore body temperature and weight. The thyroid hormones contain iodine, which the thyroid needs in order to manufacture these hormones. If a person lacks iodine in his/her diet, the thyroid cannot make the hormones, causing a deficiency. In response to the body’s feedback loops calling for more thyroid hormones, the thyroid gland then enlarges to attempt to compensate (The body’s plan here is if it’s bigger it can make more, but that doesn’t help if there isn’t enough iodine.). This disorder is called goiter.
I have always been a seafood person and since I dont live on the cost I have to make sure I get enough tuna, lobster, and seaweed in my diet to avoid the above disorder called goiter. Once the government added iodine to our salts this has alleviated many problems.

Parts of the brain

The brain.... I learned about the frontal lobe, parietal lobe, and occipital lobe and each of there locations. We then went into learning what the falx cerebelle was and this seperates the cerebellum hemisphers. Within the cerebellum is the muscle motor activity is coordinated from and the pre central gyrus is where the muscle impulses originate. We also learned locations of several parts of the brain like corpus callosum, septum pellucidum, fornix, anterior cerebral artery, frontal lobe, anterior commissure, tuberal area, fourth ventricle, cerebellum, and hypothalamus which to me was the most interesting of all. Here is a important control and integrative center. The hypothalmic may be stumulated by sensory information from the cerebrom, brain stem, and spinal cord, changes in the csf and lastle a chemical stimuli in the circulating blood. I recommend a Sagittal section view to me this was most helpful in understaning and seeing all the parts.

wk # 2&3

Today we talked about the Central nervous system. (CNS) Which is a portion of the nervous system that consists of the brain and spinal cord. We learned functions, mafor parts, meninges, nourishment, organization, skeletal prtection, and damage/repair. What i found to be most interesting is the funtions of the neurons which are responsibel for most of the unique funtions of the nervous system. The cell body contains a nucleus surrounded by cytoplasm within the cplasm organelles like lysomomers, mitochondria, and the Golgi complex are found here.
Most nuerons have an imput regions called dendrites that recieve information and integration region the cell body that analyzes all the information. Then the output is the axon and here the information is transmited toward another cell.
