Lecture 13- Lymphatic System by Dr. Istiak Mahfuz
... The only lymphatic tissue identified in lampreys to date is gut-associated lymphatic tissue (GALT) which is also present in higher vertebrates (Flajnik, 2007; Varner, 1991). In jawless fish, the spleen is not a separate organ, but rather diffuse tissue associated with the digestive tract (Torrey, 19 ...

Cardiac physiology
Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.
