Content Overview
The Essentials of Human Anatomy and Physiology Marieb is organized into several key sections, each focusing on different body systems and functions.
1. Introduction to Anatomy and Physiology
This section lays the groundwork for understanding the human body. Topics include:
- Levels of Structural Organization: Understanding how cells form tissues, tissues form organs, and organs form systems.
- Homeostasis: The body's ability to maintain stable internal conditions despite external changes.
2. The Integumentary System
The integumentary system, which includes the skin, hair, and nails, plays a vital role in protection, regulation, and sensation.
- Functions:
- Protection from external damage
- Regulation of body temperature
- Sensory reception
3. The Skeletal System
The skeletal system provides structure, support, and protection for vital organs.
- Components:
- Bones
- Cartilages
- Joints
- Functions:
- Framework for body shape
- Mineral storage (calcium and phosphorus)
- Blood cell production in bone marrow
4. The Muscular System
Muscle tissue is responsible for movement and maintaining posture.
- Types of Muscle:
- Skeletal Muscle: Voluntary and striated, attached to bones.
- Cardiac Muscle: Involuntary, found in the heart.
- Smooth Muscle: Involuntary, found in walls of hollow organs.
5. The Nervous System
The nervous system is the control center of the body, responsible for processing information and coordinating bodily functions.
- Divisions:
- Central Nervous System (CNS): Brain and spinal cord.
- Peripheral Nervous System (PNS): Nerves extending throughout the body.
6. The Endocrine System
This system regulates bodily functions through hormones.
- Major Glands:
- Pituitary
- Thyroid
- Adrenal
- Functions:
- Regulation of metabolism
- Control of growth and development
- Response to stress
7. The Cardiovascular System
The cardiovascular system consists of the heart and blood vessels, transporting nutrients, gases, and waste products.
- Components:
- Heart
- Blood vessels (arteries, veins, capillaries)
- Functions:
- Delivery of oxygen and nutrients to tissues
- Removal of carbon dioxide and wastes
8. The Respiratory System
The respiratory system facilitates gas exchange, allowing oxygen to enter the body and carbon dioxide to be expelled.
- Key Structures:
- Lungs
- Trachea
- Bronchi
- Functions:
- Oxygenation of blood
- Regulation of blood pH
9. The Digestive System
This system breaks down food into nutrients for energy, growth, and cell repair.
- Major Organs:
- Mouth
- Stomach
- Intestines
- Processes:
- Ingestion
- Digestion
- Absorption
10. The Urinary System
The urinary system removes waste products from the blood and regulates water and electrolyte balance.
- Components:
- Kidneys
- Ureters
- Bladder
- Functions:
- Filtration of blood
- Regulation of blood volume and pressure
11. The Reproductive System
The reproductive system is involved in the production of offspring.
- Male and Female Systems:
- Male: Testes, prostate, penis
- Female: Ovaries, uterus, vagina
- Functions:
- Production of gametes (sperm and eggs)
- Hormonal regulation of reproductive processes
