Final answer:
The digestive system's need for increased blood circulation during the process of digestion leads to the brain instructing the cardiovascular system to elevate heart rate, which is linked to bpm. The muscular system assists with peristalsis, and the digestive provides nutrients supporting heart function.
Step-by-step explanation:
The link between the digestive system and bpm (pulse rate) involves the close cooperation of various body systems. The digestive system needs more blood to perform its functions when digesting food. Therefore, the brain signals the cardiovascular system to increase the heart rate and dilate blood vessels in the digestive organs, which results in a higher pulse rate. The muscular system is also involved as it drives the process of peristalsis, moving the food through the digestive tract. Additionally, the digestive system supplies nutrients to the heart to support its function, illustrating the interdependence between the systems. The digestive and endocrine systems are also connected, as hormones influence digestion, and in turn, digestion provides nutrients that fuel endocrine functioning.
