Use images to discuss the structure and function of the circulatory system.
Show the 3 tunica of an artery and the function of each. Discuss the flow of blood from artery to arteriole to arteriole capillary. Explain how substances are diffused into and out of the capillaries, and view a diagram of a capillary bed with single file blood cells passing through.
Discuss how valves prevent back flow in veins, which have little or no pressure to propel the blood.
Outline the systemic circulation, the pulmonary circulation, the hepatic circulation, the renal circulation, and the fetal circulation.
The conduction pathway through of the heart is viewed through images and outline. Starting with the pacemaker, into the AV node, along the bundle of His, and down to the apex of the ventricles. Through this pathway, both atria both ventricles will contract at the same time.
The effect of both the sympathetic and parasympathetic nervous system on the rate of heart beat is outlined and the reasons for the increase and decrease discussed.
Pressure receptors and chemical receptors in the Aorta and arteries are seen to adjust the heart rate based.

Lesson Comments
Nina was in person again today, it allows for a better interaction.
Using photos and images, the coronary vessels are seen branching off the Aorta as soon as it exits the heart. Their function and importance in supplying oxygen and nutrients to all myocardial cells stressed.
The development of the heart sounds of "lub-dub" explained, the meaning of systole and diastole explained, and how a murmur is detected is explained.
The cardiac conduction pathway is outlined and the action of the pacemaker explained.
During today's class, we watched several videos that helped Lena to memorize and understand the concepts that we have been working on during the last week.
External and internal structure of the human heart.
Discuss and view through images; size, location, 3 layer pericardium, myocardium, septum separation, function of both halves, atrium, ventricles, valves, vena cave, pulmonary veins, pulmonary arteries, aorta, and cardiac ateries.
During today's class, we continued working on the Integumentary System. We talked about the nails, their functions, and anatomy and physiology. Lena took the quiz and scored 80.
Today, we have continued working on the integumentary system. Today, we learned how the skin is the biggest organ in our body. We learned the difference parts of the skin, then we watched a short video and Lena took her notes.
