Which of the following statement best describes endocrine glands?
They secrete their products into ducts.
They release their secretions on an internal surface.
They secrete chemicals into blood.
They include the salivary glands.
The Correct Answer is C
Blood then carries them to target cells or organs throughout the body. Hormones are chemical messengers that help to regulate various physiological processes such as growth, metabolism, and reproduction. Unlike exocrine glands (option a), which secrete their products into ducts that carry them to external surfaces such as the skin or digestive tract, endocrine glands have no ducts and release their secretions directly into the circulatory system. Salivary glands (option d) are exocrine glands that secrete saliva into ducts leading to the mouth. Option b is also incorrect as it does not accurately describe endocrine glands.

Explanation
The anatomical position is a standardized reference position used to describe the human body. In this position, the person stands erect with their feet together and their arms at their sides, with the palms of the hands facing forward (anteriorly). This position is used as a reference for describing the location of different parts of the body.
Correct Answer is A
Explanation
Lysosomes contribute to phagocytosis in white blood cells by fusing with the phagosome, which is the membrane-bound vesicle that engulfs the foreign particle or pathogen during phagocytosis. The lysosomes contain hydrolytic enzymes that can break down the engulfed material, thereby helping to destroy the invading pathogen. Additionally, lysosomes can also release reactive oxygen species and other antimicrobial molecules that further aid in the destruction of the pathogen.
Vacuoles, endoplasmic reticulum, and Golgi apparatus do not directly contribute to phagocytosis in white blood cells. Vacuoles are used for storage in cells, while the endoplasmic reticulum and Golgi apparatus are involved in protein synthesis and processing.
