Answer:
1. The blood entering the right side of the body contains <u>un-
oxygenated</u> blood (B).
2. All arteries carry oxygenated blood EXCEPT the <u>pulmonary</u> artery.
3. What structure brings blood to the right atrium? Superior and inferior vena cava (D).
Explanation:
The cardiovascular system is responsible for getting blood to organs throughout the body, through the joint function of the heart and blood vessels.
The circulation of the blood has been divided into two circuits:
- The major circulation, which includes the exit of blood from the heart to the arterial system, to go to the whole body. This circuit is closed with the arrival of blood to the heart through the system of venous vessels.
- The minor circulation consists of the passage of blood from the right ventricle to the lungs, and from these to the left atrium.
The blood that reaches the right atrium —entering to right side— proceeds from the superior and inferior vena cava, and is non-oxygenated blood.
In the minor circulation, the pulmonary arteries exit the right ventricle, carrying non-oxygenated blood to the lungs, being the <u>only arteries to carry venous blood</u>.

The testes are contained in the scrotum and are composed of dense connective tissue containing around three hundred internal compartments called lobules. Each of these lobules contains a number of coiled, tiny tubules where the sperm are produced. Testosterone is produced in cells located in between the lobules

She must wear a mask and gloves. The mask would prevent her from inhaling pathogens that get transferred viraly, while latex gloves would prevent pathogens from entering through her skin, or if she later decides to put her fingers in her mouth or anything similar. If she has a wound on her hands the gloves will also prevent the blood from mixing with her own and prevent disease.
