Outline and discuss both nervous control and chemical control of respiration.
Discuss the anatomy and physiology of the inspiration and exhalation centers in the medulla and the pons.
Explain and outline how the baroreceptors detect stretch in the lungs and generate impulses to the medulla to depress the inspiration centers.
Indicate and explain how fright and anger can effect the rate of respiration from the cerebral cortex to the hypothalamus to the centers in the medulla and eventually to the respiratory muscles.
Discuss the physiology behind coughs, sneezing, yawning, and hiccups.
Chemical respiration involves the effect of blood pH, levels of carbon dioxide, and levels of oxygen.
Show chemically how hypoxia is detected by chemoreceptors and transmits sensory impulses to the medulla to increase the rate of respiration.
Discuss hypercapnia, the increase of carbon dioxide, the production of carbonic acid and the lowering of the blood pH producing acidosis.
Show how alkalosis occurs when the rate of respiration increases and the pH increases.
Outline the effects on the body systems of both acidosis and alkalosis.

Review of Monday's lesson using a classwork activity.
Introduce Boyle's Law which discusses the relationship between pressure of a gas and its volume.
Recall how the Medulla contains respiratory centers which send nerve impulses to the diaphragm and the intercostal muscles.
Outline and discuss the complete physical mechanism of inhalation and exhalation, the movement of the ribs and diaphragm causing a difference in pressure between the atmosphere and the thoracic cavity.
Discuss external and internal respiration, along with the chemical makeup of air.
Present some clinical applications describing asthma, congestive heart failure leading to dyspnea and hypoxia, along with bacterial pneumonia.

Initiated by listening to the voice of Sinatra and discovering what is meant by learned and efficient breathing which led into an in-depth examination of the upper and lower respiratory system.
This included, but was not limited to, the anatomy and physiology of the nose, pharynx, larynx, upper trachea, bronchi, lungs, and alveoli.

Outline and discuss adaptive immunity.
Cell mediated adaptive immunity-
Antibody mediated adaptive immunity-
Discuss the antibody response and outline the process.
Discuss how antibodies function to agglutinate pathogens.
Outline and discuss both genetic immunity and acquired immunity.
Differentiate between naturally and artificially acquired passive immunity.
Differentiate natural active immunity from artificial active immunity.

Definition of immunity-
Definition of antigen-
List and discuss 5 common types of antigens-
Discuss innate immunity; barriers, defensive cells, and chemical defenses.
Include in the above skin, mucus membranes, WBC's, neutrophils, eosinophils, natural killer cells, basophils, and mast cells.
Chemical defenses include interferons, complement, and inflammatory chemicals.

Outline and discuss the functions of the lymphatic system, including return of tissue fluid to the blood and protection against foreign substances and pathogens.
List and examine the major parts of the system:
Lymph, which is tissue fluid from blood plasma. Lymph vessels including lymph capillaries and "vein like" structures. Lymph tissue composed of lymphocytes, lymph nodes, and lymph nodules.
Examine the makeup, location, and function of each. Discuss the function of the spleen in immunity and the production of bilirubin and eventually bile. Examine the thymus gland, the hormone produced, and the effect the hormone has on the immunological competence of the T lymphocytes produced.

During today's class, Lena finished watching some of the review videos that I had planned for her and after that, we cleaned her room.

End the unit on reproduction by discussion a variety of related subjects. These include a look at comparative embryology involving 6-7 different species and examining how closely related they all appear in the embryological phase. Examine neonatal testing methods used to determine the possibility of specific disorders. These include amniocentesis, chorionic villi examination, and the production of sonograms.

During today's class, we continued watching some videos as a review of the material that we have covered during this course. Lena loved the videos and she had a great class.

View from images the process of cleavage of the zygote. The formation of the morula, blastocyst, and embryonic stem cells.
Show the formation of the germ layers into the ectoderm, mesoderm and endoderm. View a list of the organs and tissues that each of the germ layers will develop into due to specialization.
