Function of the cardiac muscle?
It contracts and relaxes continously during the animal life time.
The cardiac muscle is what makes the heart beat. Without this muscle the heart could not carry out its function of keeping us alive. The cardiac muscle is what is called an 'involuntary' muscle, as it contracts without us consiously being aware of it. The cardiac muscle continues to contract if it has a sufficient supply of oxygen and nutrients.
How does the structure of cardiac myocytes and intercalated discs follow the function of cardiac muscle tissue and the heart?
The myocard (cardiac muscle), the muscle that makes your heart pump, needs oxygen to function. This oxygen is distributed through the blood that flows in the coronary arteries, which lie around the cardiac muscle. When there is not enough oxygen in your blood, the cardiac muscle does not get enough oxygen to fully function and your heart will not be able to function, over time. This starts at about 3 minutes after stopping to get…
