Study Notes

Human Body Systems Overview

The human body consists of interconnected systems that maintain life.

Skeletal System

Composed of bones and cartilages, totaling 206 bones in an adult.
Divided into axial (bones of the head and trunk) and appendicular (limbs and girdles).
Functions include support, movement, protection, blood cell production, calcium storage, and hormone regulation.
Joints, where bones connect, are supported by cartilage and ligaments.

Muscular System

Made up of smooth, cardiac, and skeletal muscles.
Smooth muscles line blood vessels and hollow organs; cardiac muscle forms the heart; only skeletal muscles are under voluntary control.

Cardiovascular System

Consists of the heart with four chambers (two atria and two ventricles) and blood vessels.
Responsible for transporting oxygen, nutrients, and waste products throughout the body.
Heart valves prevent backflow of blood.

Respiratory System

Comprises the upper (nasal cavity, pharynx) and lower (larynx, trachea, bronchi, lungs) respiratory organs.
Main function is gas exchange: bringing in oxygen and expelling carbon dioxide.

Lymphatic System

A network of vessels that drains excess fluid (lymph) and supports immune response through lymph nodes.
Primary organs include thymus and red bone marrow; secondary organs include lymph nodes, tonsils, and spleen.
Functions to eliminate toxins and waste, recirculate proteins, and defend against microorganisms.

Digestive System

Involves the gastrointestinal tract (mouth to anal canal) and accessory organs (liver, pancreas, etc.).
Breaks down food into smaller compounds for nutrient absorption.
Digestive processes are supported by hormones and nerve signals.

Endocrine System

Comprises specialized glands producing hormones that regulate bodily functions.
Hormones like triiodothyronine (metabolism) and estrogen/progesterone (menstrual cycle) play significant roles.
Acts as a messenger system, influencing distant organs via the circulatory system.

Reproductive System

Composed of external and internal sex organs, differing significantly between male and female.
Female organs support egg production and fetal development (ovaries, uterus, vagina).
Male organs facilitate sperm production and delivery (testes, penis, epididymis).

Urinary System

Consists of kidneys, ureters, urinary bladder, and urethra, functioning as a waste elimination system.
Kidneys filter blood and form urine, which is stored in the bladder before excretion.
Regulates blood volume, pressure, electrolyte levels, and blood pH.

Body Posture

Understanding posture is crucial as improper alignment can lead to pain and reduced flexibility.
Good posture affects overall balance and range of motion, influencing back and neck health.

Fundamental Body Movements

Divided into locomotor (moving body), non-locomotor (movement without travel), and manipulative (using objects).

Locomotor Movements

Includes walking, running, hopping, leaping, jumping (even movements) and skipping, galloping, sliding (uneven movements).

Non-locomotor Movements

Involve movements like bending, twisting, lifting, and swinging, often combined with locomotor actions.
