These hormones, such as testosterone in males and estrogen and progesterone in females, play a crucial role in the development and functioning of the reproductive organs. The exocrine glands, such as the prostate gland and seminal vesicles in males and the mammary glands in females, secrete substances that are important for reproduction. Together, these steroid sex hormones and exocrine glands contribute to the overall reproductive function in both males and females.Rate this question:

.……………….carry deoxygenated blood toward the heart.
- A.
Arteries
- B.
Capillaries
- C.
Veins
- D.
Blood
Correct Answer
C. VeinsExplanation
Veins carry deoxygenated blood toward the heart. Unlike arteries, which carry oxygenated blood away from the heart, veins transport blood back to the heart after it has delivered oxygen and nutrients to the body's tissues. This deoxygenated blood is then pumped to the lungs to be reoxygenated before returning to the heart and being circulated again. Capillaries, on the other hand, are the smallest blood vessels that connect arteries and veins, allowing for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.Rate this question:

Correct Answer
C. Digestive processesExplanation
The given answer "digestive processes" is correct because it encompasses all the stages mentioned in the question - ingestion, movement of food, digestion, absorption, and defecation. Digestive processes refer to the various physiological and biochemical processes that occur in the digestive system to break down food into nutrients that can be absorbed by the body. These processes involve the movement of food through the digestive tract, peristalsis being one of the mechanisms responsible for this movement. Overall, "digestive processes" is a comprehensive term that encompasses all the stages of food processing mentioned in the question.Rate this question:
