The human body has two major circulatory systems: the blood and lymphatic systems. Although the blood vascular system and the lymphatic system operate in parallel and share some anatomical features, the two vascular systems have had very different fates in science and medicine, as they display distinct structural and functional features. While the blood system has been extensively studied and examined, the lymphatic system has been neglected and considered as less important compared with the…

1. Discuss what a neuron is and the functions of its basic parts (dendrites, soma, axon, myelin sheath). A neuron is a nerve cell. There are about 10,000 specific types of neurons, but there are three most common neurons: sensory, motor, and interneurons. A sensory neuron sends signals to help your brain understand what is going on around you in your environment. Sensory neurons are what make up your senses, (smell, touch, see, taste, and hear.)…

AIDS-related lymphomas are very complex diseases with many factors to consider. It is important to understand the origin of AIDS-related lymphoma. According to the article “AIDS-Related Malignancies,” AIDS-related lymphoma is believed to be…

Your Inner Fish by Neil Shubin Chapter Questions Chapter 1 – Finding Your Inner Fish 1. Explain why the author and his colleagues chose to focus on 375 million year old rocks in their search for fossils.

The author and his colleagues chose to focus on 375 Million Years as it was a period when the transformation took place from fish to fish with limb. The fish without characteristics of…

vitamin D), antioxidants (e.g. vitamin E), and mediators of cell signaling and regulators of cell and tissue growth and differentiation (e.g. vitamin A). The largest number of vitamins (e.g. B complex vitamins) function as precursors for enzyme cofactor bio-molecules (coenzymes), that help act as catalysts and substrates in metabolism. When acting as part of a catalyst, vitamins are bound to enzymes and are called prosthetic groups. For example, biotin is part of enzymes involved in making…
