5.1.1 Under My Skin
In this activity, we were introduced the basics of the largest organ of the human body, the skin. We explored the layers and parts that make up the skin. We then created a 3D model of the layers of the skin, as seen below. The parts labeled include Epidermis, Dermis, Subcutaneous layer (fat lobules), Nerves, Blood vessels, Sebaceous gland, Sweat gland, Hair follicle, Arrector pili muscle and the Dermal papillae.

5.2.1 Looking Inside Bone
In this activity, we explored a long bone of cow. A long bone is hard and strong that provides strength, structure, and mobility. It has a shaft and two ends, that made it easy to dissect and label the components of bone. The following components of the long bone can be seen below: epiphysis, diaphysis, cartilage, periosteum, compact bone, spongy bone, medullary cavity, red marrow (found in spongy bone), and yellow marrow (found in the medullary cavity).

5.2.3 Bone Remodeling and Repair
In this activity, we explored the functions that calcium plays in our body and the negative feedback response of high/low blood calcium levels. Calcium serves as the main component of bone, making it strong, yet dense. It also serves for muscle contraction, nerve signaling, and blood clotting. The negative feedback of blood calcium can be seen in the feedback loop below.

5.3.1 To Drain and Protect
In this activity, we explored the organs and key components that make up the lymphatic system. We also researched how the lymphatic and immune system work together to protect the body from infection. Five key components (tonsils, thymus, spleen, lymph nodes and the liver) of the lymphatic system can be found in the body system organizer below:

5.3.2 Transfusion Confusion
In this activity, we explored the characteristics, genetics, donors, and recipients of the four blood types (A, B, AB, and O). We then created a pedigree of the Doe family to see how blood type passes down within a family.
