Summary Introduction

To determine:

The arrangement of two types of T-lymphocytes in cortex and medulla.

Concept introduction:

Lymphatic system is comprised of lymphatic tissues or organs like, tonsils, lymph nodes and nodules, spleen and MALT. These lymphoid organs or tissues are classified as primary and secondary structures. The B and T-lymphocyte are the major type of lymphocytes which are formed in red bone marrow.

Normal dive (for diving humans) normal breathing dive normal breathing Oz level CO2 level urgent need to breathe Oz blackout zone high CO2 triggers breathing 6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in diving humans. How might the location and slope of the O₂ line differ for diving marine mammals such as whales and dolphins? • How might the location and slope of the CO₂ line differ for diving marine mammals such as whales and dolphins? • • Draw in predicted lines for O2 and CO2, based on your reasoning above. How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line differ for diving marine mammals? What physiological mechanisms account for each of these differences, resulting in the ability of marine mammals to stay submerged for long periods of time?
