What is heart?

Heart is defined as an organ that pumps blood throughout your body and is around the size of your fist. It is composed of numerous tissue layers. The core of your circulatory system is your heart. The heart is an important organ. It is a muscle that helps your body's blood flow throughout. The blood that your heart pumps provides your body with the oxygen and nutrition it needs to function.

The human heart is located in the mediastinum, which is a portion of the thoracic cavity located medially between the lungs. Low oxygen blood is taken from the body and pushed through the right atrium to the right ventricle. The blood with less oxygen is sent to the lungs via the right ventricle. Blood that is rich in oxygen is drawn from the lungs and pumped to the left ventricle by the left atrium.

Thus, size-wise, your heart occupies about 1/4th of the space in your upper chest. Hence option B is correct.

What is the function of the serous membrane? (Be specific about what types of body cavities)

Answers

To transfer semen from the uterus to the finger nails

Answer:
