Questions with answers on “Immune System: Innate and Adaptive Immunity”
1. What are the key differences between innate immunity and adaptive immunity? Answer:Innate immunity is the body's first line of defense and is non-specific, meaning it does not differentiate between different pathogens. It includes physical barriers such as skin and mucous membranes, and chemical defenses like stomach acid. Cells such as phagocytes (neutrophils and macrophages) and natural killer cells play...

Understanding the Skeletal and Muscular Systems: The Foundation of Movement and Support
Introduction The human body is a complex machine that requires a well-coordinated interaction between various systems to function effectively. Among these, the skeletal and muscular systems play a pivotal role in providing structure, support, and enabling movement. The skeletal system forms the rigid framework of the body, while the muscular system facilitates movement by generating forces through muscle contractions. Together,...
Questions with answers on the topic “Skeletal and Muscular Systems: Movement and Support.”
1. Explain the structure and function of long bones in the skeletal system. Answer:Long bones, such as the femur and humerus, are characterized by a long shaft and two distinct ends, which are called epiphyses. The shaft, or diaphysis, contains a medullary cavity that stores bone marrow. The ends of long bones are covered with articular cartilage, which reduces friction...

The Role of Kidneys in Homeostasis: A Deep Dive into the Excretory System
Introduction The excretory system plays a crucial role in maintaining the internal environment of the body, ensuring that waste products and excess substances are removed, while vital substances are conserved. At the heart of this system is the kidney, which not only helps eliminate waste but also contributes to homeostasis—the body's ability to maintain stable internal conditions despite external changes....
Questions with answers on the topic “Excretory System: Role of Kidneys in Homeostasis”
1. What is the role of kidneys in maintaining homeostasis in the human body? Answer:The kidneys play a crucial role in maintaining homeostasis by regulating the balance of water, salts, and waste products in the body. They filter blood to remove metabolic waste products such as urea, uric acid, and creatinine, and also regulate the levels of electrolytes like sodium,...

What is the primary function of the kidneys in the human body?a) Blood circulationb) Regulation of body temperaturec) Filtration of blood and regulation of homeostasisd) Protein synthesis Answer: c) Filtration of blood and regulation of homeostasis 2. The functional unit of the kidney is known as the:a) Neuronb) Nephronc) Glomerulusd) Alveolus Answer: b) Nephron 3. Which part of the nephron is responsible...
The Endocrine System: Hormones and Gland Functions – A Comprehensive Guide
Introduction The endocrine system plays a crucial role in regulating numerous physiological processes within the human body, including metabolism, growth, mood, and reproduction. Unlike the nervous system, which uses electrical signals to transmit information rapidly, the endocrine system relies on chemical messengers called hormones. These hormones are secreted by various glands throughout the body, which collectively make up the endocrine...

1. Explain the function and importance of the pituitary gland in the human endocrine system. Answer:The pituitary gland, often referred to as the "master gland," plays a central role in regulating various physiological processes. It is located at the base of the brain and controls the functions of many other endocrine glands. The pituitary secretes hormones that influence growth, metabolism,...
