In this episode, we focus on the lymphatic system, a crucial topic for the Bio/Biochem section of the MCAT. We'll cover the structure of the lymphatic system, including lymphatic vessels, lymph nodes, and major organs such as the bone marrow and thymus. You'll also learn about the system’s primary functions: returning fluid to the blood, supporting the immune system, and absorbing fats and fat-soluble nutrients.

Hosts Sam Smith and Alex Starks break down how the lymphatic system plays a vital role in immunity, nutrient absorption, and fluid balance. By the end of this episode, you'll gain a deeper understanding of the lymphatic system's anatomy and physiology, helping you prepare for MCAT-related questions.

Aging is an essential topic for the MCAT, and in this episode, we’ll explore it from multiple angles. We start with the biological aspects of aging, including key processes like telomere shortening, cell senescence, and mitochondrial dysfunction—each providing insight into how and why cells age. From there, we dive into how aging impacts the brain, including the types of memory and cognitive functions that either decline or improve with age. Lastly, we’ll cover the sociology of aging, focusing on the life course theory, the social significance of aging, and demographic changes.

Expect a comprehensive breakdown of these concepts, with real-world applications and examples to reinforce your understanding.
