Explanation:
Birds and mammals have a double circulatory system and a four-chambered heart which separates the oxygenated blood and the deoxygenated blood from each other in the heart. This system of circulation is necessary to serve the high energy needs of the mammals and birds.
In this system, deoxygenated blood from the body passes through the superior and inferior Vena Cava into the right atrium. From the right atrium it flows into the right ventricle. From the right ventricle, it is then pumped into the pulmonary artery to be carried to the lungs. In the lungs, the deoxygenated blood is oxygenated and returned to the heart through the pulmonary veins.
Oxygenated blood enters the left atrium from the lungs through the pulmonary veins. It then moves into the left ventricle. In the left ventricle, it is then pumped into the aorta. The aorta is a large vessel that runs the length of the vertebral column, branching off to be circulate blood in the body system.
B) Broad ligament
C) Suspensory ligament
D) Ovarian ligament
Answer:
D) Ovarian ligament
The ligament that connects the ovary to the uterus is called the ovarian ligament.
Explanation:
The ovarian ligament is attached to the ovary inferiorly. It connects the ovary to the side of the uterus. Structurally, it is a fibrous band of tissue that lies within the broad ligament.
The Ovarian ligament is the cylindrical band that connects the ovary to the uterus. Other ligaments like the Round ligament, Broad ligament, and Suspensory ligament have other roles within the female reproductive system.
The ligament that connects the ovary to the uterus in a cylindrical band is the Ovarian ligament (option D). The ovarian ligament is a fibrous cord that connects the ovary to the lateral surface of the uterus. This plays an important role in the female reproductive system by helping to keep the ovary in place.
Just to clarify further, the Round ligament is a ligament that connects the front of the uterus to the groin area; the Broad ligament is a broad fold of peritoneum that envelops the uterus, associated structures, and adjacent parts of the abdominal wall; the Suspensory ligament is a peritoneal ligament extending from the hilum of the ovary to the wall of the pelvis and contains the ovarian vessels.

Answer:
This is true. As the intensity of exercise increases, the body relies more on fat as the primary fuel source for energy production. This is because fat is the most energy-dense source of fuel in the body, providing approximately 9 kcal per gram, compared to only 4 kcal per gram for carbohydrates. Additionally, the body's ability to oxidize fat increases at higher exercise intensities, allowing for a greater proportion of the fuel supply to come from fat. However, the body's ability to oxidize fat is limited, so at very high exercise intensities, carbohydrates become the primary fuel source.
