1. The heart is located in the mediastinum

Explanation

The heart is located in the mediastinum, which is the central compartment of the thoracic cavity. It is bounded by the sternum in front, the vertebral column at the back, and the lungs on either side. The heart is positioned slightly to the left side of the mediastinum, and it is surrounded and protected by the pericardium. The mediastinum also contains other vital structures such as the great vessels, esophagus, and trachea. Therefore, the statement that the heart is located in the mediastinum is true.

2. Math the following valves to the side of the heart they are found:

Explanation

Also known as the right or left atrioventricular valves

3. The heart has 3 layers of tissue:1) Epicardium: outer surface2) Myocardium: middle muscular layer &3)?

Explanation

The correct answer is "Endocardium." The endocardium is the innermost layer of tissue in the heart. It lines the chambers of the heart and covers the heart valves. This layer is made up of a thin layer of endothelial cells and connective tissue. The endocardium helps to prevent blood clots and provides a smooth surface for blood flow within the heart.

5. What is fibrous pericardium?

Explanation

The fibrous pericardium refers to the thick outer layer of membrane that surrounds the heart. This layer provides protection and support to the heart, helping to maintain its shape and integrity. It is composed of tough, fibrous connective tissue that helps to prevent overstretching of the heart during contractions and movements.

8. Capillaries transport substances to and from cells. Select the substances below which are transferred in capillary exchange:

Explanation

Capillaries are tiny blood vessels that connect arteries and veins. They play a crucial role in the exchange of substances between the blood and the surrounding cells. Oxygen (O2) is transported from the lungs to the cells through capillaries, while waste products are carried away from the cells to be eliminated. Additionally, capillaries also transport hormones, which are chemical messengers that regulate various bodily functions. Lastly, nutrients, such as glucose and amino acids, are delivered to the cells through capillaries to provide energy and support cellular processes.
