The Lymphatic System

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.
