How is the human body described in terms of structure and function at the beginning of the text? - The human body is described as a well-structured system that ensures the coordinated operation of the entire organism. It includes not only the musculoskeletal system, but also internal organs, nervous regulation, and biochemical processes working together to maintain balance and function., What are the four main levels of biological organization mentioned in the hierarchical structure of the human body, and what is their significance? - Cellular level – the basic structural and functional unit of life.Tissue level – groups of similar cells with a shared function.Organ level – structures composed of multiple tissues performing specific tasks.Systemic level – groups of organs working together to perform complex functions.These levels show how the body’s complexity is organized and how structure supports function., What are the key properties of a cell that make it the basic unit of life? - Cells have the abilities of metabolism, irritability (response to stimuli), reproduction, and self-regulation. These properties enable them to sustain life and contribute to the functioning of the entire organism., How are tissues formed, and what are the four main types of tissues described in the text? - Tissues are formed when cells with the same structure and specialization group together. The four main tissue types are:Epithelial, connective,muscular,nervous, What is the relationship between tissues, organs, and organ systems according to the passage? Give examples. - Tissues combine to form organs, and organs work together to form organ systems.Example: Muscle and connective tissues form the heart (an organ), which is part of the cardiovascular system, working with blood vessels to transport substances through the body., What components make up the musculoskeletal system, and what are the specific functions of each component? - The musculoskeletal system consists of:Bones (skeleton): provide support, protection, and mineral storage (e.g., calcium).Muscles: enable movement.Ligaments and joints: offer stability and flexibility to the body., How do muscles, tendons, ligaments, and joints work together to facilitate movement and maintain body stability? - Muscles contract to create movement. Tendons connect muscles to bones, transmitting the force of contraction.Ligaments connect bones to each other, providing stability.Joints act as pivot points that allow bones to move smoothly., What are the main parts of the nervous system, and what functions does each part perform? - Central Nervous System (CNS): brain and spinal cord — responsible for control, coordination, and processing of information.Peripheral Nervous System (PNS): nerves outside the CNS — transmits signals between the CNS and the rest of the body., Explain how the cardiovascular and respiratory systems are functionally connected. What roles do the heart and lungs play? - The heart pumps blood through vessels, transporting oxygen, carbon dioxide, nutrients, and hormones.The lungs perform gas exchange, supplying oxygen and removing carbon dioxide.Together, they maintain the body’s oxygen supply and support cellular respiration and metabolism., What is the role of the lymphatic system, and why is it considered important despite often being underestimated? - The lymphatic system drains excess interstitial fluid, transports immune cells, and serves as a defense barrier against infections., List the main glands of the endocrine system mentioned in the text and explain the general function of this system. - Pituitary,thyroid,adrenal glands, What distinguishes the autonomic nervous system from the rest of the nervous system, and what functions does it control? - The autonomic nervous system (ANS) operates independently, without conscious control.It regulates involuntary functions such as heartbeat, peristalsis, glandular secretion, and smooth muscle activity in internal organs., Why is it important to understand the interrelationships between body systems when attempting to restore bodily functions? - Because the body functions as an integrated whole, restoring one function often requires understanding how it interacts with others. A systematic approach based on anatomical and physiological unity is essential for effective treatment and recovery.,
