3.1 Mechanical Digestion:
Mechanical digestion involves physical breakdown of food through chewing, churning in the stomach, and segmentation in the intestines.
3.2 Chemical Digestion:
Chemical digestion utilizes enzymes to break down complex carbohydrates, proteins, and fats into simpler molecules like glucose, amino acids, and fatty acids.
3.3 Absorption and Elimination:
Nutrients are absorbed in the small intestine and transported to the bloodstream, while waste products are eliminated through the large intestine. Problems with digestion can lead to malnutrition and other health issues.
4. Excretion: Waste Removal
Excretion involves the removal of metabolic waste products from the body. The primary organs involved are the kidneys, lungs, skin, and liver. These organs work together to filter blood, remove toxins, and maintain the body’s internal balance.
4.1 Kidney Function:
The kidneys play a critical role in filtering blood, removing urea and other waste products, and regulating fluid balance.
4.2 Other Excretory Organs:
The lungs excrete carbon dioxide, the skin excretes sweat, and the liver processes and eliminates various toxins. Disruptions in excretion can lead to the accumulation of harmful substances in the body.
5. Movement: Mobility and Coordination
Movement encompasses the coordinated actions of muscles and skeletal system, enabling locomotion, posture maintenance, and other bodily functions.
5.1 Musculoskeletal System:
The musculoskeletal system is crucial for movement, involving bones, muscles, tendons, ligaments, and joints. Movement allows us to interact with our environment and perform daily activities.
5.2 Neurological Control:
The nervous system plays a vital role in coordinating and controlling movement. Signals from the brain and spinal cord direct muscle contractions, allowing for precise and controlled movements.
6. Nervous System Function: Control and Coordination
The nervous system, comprising the brain, spinal cord, and nerves, is responsible for receiving, processing, and transmitting information throughout the body. It controls and coordinates all other vital functions.
6.1 Sensory Input:
Sensory receptors throughout the body detect changes in the internal and external environment, transmitting this information to the central nervous system.
6.2 Motor Output:
The nervous system directs motor responses, coordinating muscle contractions and other bodily functions, allowing us to react to stimuli and maintain homeostasis.
6.3 Neurological Disorders:
Disorders affecting the nervous system can have far-reaching consequences, highlighting the vital nature of this system’s proper functioning.
7. Reproduction: Continuation of Life
Reproduction ensures the continuation of the species. It includes gamete production (sperm and egg) and fertilization.
7.1 Gametogenesis:
The process of creating sperm and eggs involves meiosis, a specialized type of cell division leading to genetically diverse gametes.
7.2 Fertilization and Development:
Fertilization occurs when a sperm fertilizes an egg, initiating the development of a new organism.
7.3 Reproductive System Health:
Reproductive health is crucial for overall well-being. Maintaining reproductive health is essential for both individual and species survival.
