When oxygen moves into a contracting heart muscle cell, it is used to generate energy through aerobic respiration. This energy is essential for the cell to sustain the contractile activity required for the heart to pump effectively. Additionally, oxygen helps to maintain cellular homeostasis and prevent the accumulation of harmful byproducts such as lactic acid.
Oxygen-rich blood moves from the lungs to the heart, where it is pumped out to the body through the arteries. It circulates through the body's tissues and organs, delivering oxygen and nutrients, before returning to the heart through the veins.
The heart is responsible for pumping blood throughout the body, which carries oxygen and nutrients to cells. The digestive system, which includes organs like the stomach and intestines, moves food through the body via a series of muscular contractions.
Simple answer. All your life your lungs inhale and exhale oxygen. This is facilitated by the diaphragm, a muscle just below the lungs. When this muscle moves down a partial vacuum is created allowing the lungs to inflate filling the space created by the moving diaphragm, it then moves up again compressing the lungs and therefore expelling the air in them.
The respiratory system brings oxygen into the body and the circulatory system, specifically the cardiovascular system, moves the oxygen around the body via the bloodstream.
probably oxygen
diffusion
Oxygen moves into contracting heart muscle cells primarily through passive transport processes, specifically diffusion. As the heart muscle contracts, it creates a lower concentration of oxygen inside the cells compared to the surrounding blood, facilitating the movement of oxygen from areas of higher concentration in the blood to lower concentration within the cells. This process does not require energy, allowing oxygen to efficiently enter the muscle cells during contraction.

Pulling and contracting is how a muscle moves the bones ....
Looking form the out side the two bones to which the Muscle is attached moves closer when the muscle is contracting concentrically while they do not when muscle is contracting eccentrically
Pulling and contracting is how a muscle moves the bones ....
The heart moves the blood all over the body the heart it self is no exception. The heart is a cardiac muscle.

It's true its the muscle that moves your eyes :)
The medial rectus muscle is responsible for moving the eyeball medially by contracting. This muscle is one of the extraocular muscles that control eye movements.
