Question

State 10 ways in which mammalian heart is adapted to its function???

Answer 1

Hey frnd

Muscular to pump blood over long distance;

- Myogenic cardiac muscles which contract and relax rhythmically without fatigue; hence heart continues pumping;

- Cardiac muscle fibres interconnected to form a network of fibre to ensure rapid and uniform spread of excitation throughout the walls of the heart;

- Heart divided into 4 chambers which are hollow to accommodate more blood;

- Ventricles have thicker walls than auricles to generate higher pressure to drive blood over long

distance into more elaborate  circulation/to the lungs and to all body tissues
