The Skeletal System
The skeletal system consists of 206 bones, providing support, protection, and movement; It is divided into the axial and appendicular skeleton, working together to maintain posture and facilitate bodily functions.
3.1 Overview of Bones and Joints
Bones form the structural framework of the body, with 206 bones in adults. They vary in shape: long, short, flat, irregular, and sesamoid. Joints connect bones, classified as synovial, cartilaginous, or fibrous, enabling movement, stability, and protection of internal organs.
3.2 Axial vs. Appendicular Skeleton
The axial skeleton includes the skull, spine, ribs, and sternum, totaling 80 bones. The appendicular skeleton comprises 126 bones in the limbs and girdles. Axial supports and protects vital organs, while appendicular facilitates movement and protects organs like the heart and lungs.
The Muscular System
The muscular system comprises skeletal, smooth, and cardiac muscles, each with unique roles in movement, involuntary functions, and blood circulation, essential for overall bodily functions and movement.
4.1 Types of Muscles and Their Functions
The human body contains three types of muscles: skeletal, smooth, and cardiac. Skeletal muscles enable voluntary movement and are attached to bones. Smooth muscles perform involuntary functions like digestion. Cardiac muscles are specialized for the heart, ensuring continuous pumping of blood, each playing a vital role in movement and bodily functions.
4.2 Muscle Structure and Physiology
Muscles are composed of muscle fibers containing myofibrils, which consist of sarcomeres. These units contract via the sliding filament theory, where actin and myosin filaments move. The sarcoplasmic reticulum regulates calcium ions, essential for contraction and relaxation. ATP provides energy for these processes, enabling movement and bodily functions.
4.3 Interaction Between Muscles and Bones
Muscles and bones interact through tendons, enabling movement; Muscles contract to pull bones, leveraging joints for motion. This system allows actions like walking or lifting, with bones providing structural support and muscles generating force for movement, essential for bodily functions and mobility.
The Nervous System
The nervous system controls bodily functions, integrates information, and enables responses. It consists of the central and peripheral nervous systems, coordinating actions and maintaining homeostasis effectively.
5.1 Structure and Function of the Nervous System
The nervous system consists of the central nervous system (CNS) and peripheral nervous system (PNS). The CNS includes the brain and spinal cord, processing information and controlling voluntary actions. The PNS connects the CNS to sensory receptors and effectors, enabling reflexes and involuntary functions. Together, they regulate body responses and maintain homeostasis effectively.
5.2 The Brain, Spinal Cord, and Peripheral Nerves
The brain is the control center of the nervous system, regulating thoughts, emotions, and bodily functions. The spinal cord connects the brain to peripheral nerves, facilitating reflexes and transmitting signals. Peripheral nerves link the central nervous system to sensory receptors and effector organs, enabling communication and response. Together, they ensure precise control of voluntary and involuntary functions.
5.3 Neurons and Neurotransmitters
Neurons are specialized cells that transmit and process information through electrical and chemical signals. They consist of dendrites, a cell body, and an axon. Neurotransmitters, such as dopamine and serotonin, are chemicals released by neurons to communicate with other cells, enabling functions like movement, cognition, and emotional regulation. Their imbalance can lead to disorders.
5.4 The Autonomic Nervous System
The autonomic nervous system regulates involuntary bodily functions, such as heart rate, digestion, and breathing. It comprises the sympathetic and parasympathetic systems, which balance each other to maintain homeostasis. The sympathetic “fight-or-flight” response increases energy, while the parasympathetic “rest-and-digest” promotes relaxation and restoration. Dysfunction in this system can lead to various physiological disorders.
The Circulatory System
The circulatory system transports oxygen, nutrients, and hormones via blood vessels, powered by the heart. It includes arteries, veins, and capillaries, essential for maintaining homeostasis and overall health.
6.1 Heart Structure and Function
The heart is a muscular organ with four chambers: two atria and two ventricles. It pumps blood through arteries, veins, and capillaries, supplying oxygen and nutrients. Valves ensure one-way blood flow, while the septum separates chambers. The coronary arteries nourish the heart muscle. Its electrical system regulates rhythmic contractions, enabling efficient circulation.
6.2 Blood Components and Their Roles
Blood consists of red blood cells (transport oxygen), white blood cells (fight infections), platelets (aid clotting), and plasma (carries nutrients, hormones, and waste). Each component plays a vital role in maintaining homeostasis, immune function, and overall health by ensuring proper circulation and protection against disease.
6.3 Blood Pressure and Circulation
Blood pressure drives circulation, delivering oxygen and nutrients to tissues. It is regulated by heart rate, vessel diameter, and fluid volume. Healthy levels maintain proper organ function, while imbalances can lead to hypertension or hypotension, impacting overall cardiovascular health and system efficiency.

Major Body Systems and Their Interactions
The respiratory, digestive, and urinary systems work together to maintain homeostasis, ensuring oxygen intake, nutrient absorption, and waste removal, all vital for overall bodily function and health.
8.1 Respiratory System
The respiratory system, including the nose, trachea, and lungs, facilitates gas exchange through breathing. It brings oxygen into the body and expels carbon dioxide, essential for cellular respiration and energy production, maintaining proper pH balance and overall physiological function.
8.2 Digestive System
The digestive system processes food into nutrients through mechanical and chemical digestion. Organs like the mouth, esophagus, stomach, and intestines break down food, while the liver and pancreas provide digestive enzymes. Nutrients are absorbed into the bloodstream, and waste is eliminated, maintaining energy and cellular function.
8.3 Urinary System
The urinary system, comprising kidneys, ureters, bladder, and urethra, filters blood to produce urine, removing waste and excess substances. It regulates electrolytes, pH, and fluid balance, essential for homeostasis. Proper function maintains overall health by eliminating toxins and managing bodily fluids effectively.
