2. If a persons heart rate increases it would benefit the muscular system because the heart puts more blood to the muscles making it stronger.
3. the difference between the left and right side of the heart is that the right receives oxygen-poor blood and pumps it to the lungs while the left pumps the oxygen-rich blood through and to the arteries and other parts.
4. Thats a SUPER broad question.But in layman terms. Muscles are connected to Tendons, When you want to move anything. your muscles will pull on the tendons which pull on a bone.Muscles contracting causes movement. even things where you feel like you’re pushing. its still a muscle pulling, muscles cant push, can only pull (when you “push” its your chest muscles contracting pulling your arm in towards the middle of your body, e.g pushup/bench press).
5. Unlike the small intestine, the large intestine produces no digestive enzymes. Chemical digestion is completed in the small intestine before the chyme reaches the large intestine. Functions of the large intestine include the absorption of water and electrolytes and the elimination of feces.
6. The body systems are used to address the basic needs of survival by sending signals differently to different body parts.
