ABOUT THIS SESSION

In this webinar session, Dr. Sanjay Kalra will provide a concise and engaging overview of blood cells, focusing on red blood cells, white blood cells, and platelets. The session will highlight the physiological roles of these cellular components in oxygen transport, immune defense, and hemostasis, while linking basic concepts to clinical relevance. Through a structured and easy-to-follow discussion, participants will gain a clearer understanding of how abnormalities in blood cells contribute to common hematological and systemic conditions.

Q&A

The episode explores how blood cells contribute to hormonal balance, highlighting their active involvement in endocrine signaling rather than serving only as circulating components.

Red blood cells transport certain hormones, respond to hormonal stimulation, and modify their function based on endocrine signals in the body.

Erythropoietin is the primary hormone that stimulates red blood cell production, mainly released by the kidneys.

Thyroid hormones affect red blood cell function, including their metabolic activity and efficiency in oxygen delivery.

White blood cells can release hormone-like substances that support communication between the immune and endocrine systems.

POMC acts as a precursor for biologically active peptides, reflecting the connection between immune responses and hormonal signaling

Stress-related hormonal changes can temporarily increase or decrease white blood cell numbers.

Platelets are not endocrine glands, but they release signaling molecules that act locally in the body.

Thrombopoietin regulates platelet production, primarily produced by the liver.

They carry hormones, respond to endocrine signals, and release bioactive substances that influence physiological processes.
