Study Notes
Skeletal and Muscular System
- The skeletal and muscular systems work together to move the body.
- Bones provide the structure for muscles to attach to.
- Muscles generate the force for movement, enabling limb movement and locomotion.
- Locomotion is crucial for accessing food, providing essential nutrients and maintaining homeostasis.
Kidney
- The kidney is vital for maintaining overall body homeostasis.
- It regulates extracellular fluid volume and electrolyte concentrations.
- It balances the body's acid-base levels.
- It filters waste products from the blood.
- It produces hormones: erythropoietin (stimulates red blood cell production), renin (regulates blood pressure), and calcitriol (promotes phosphate reabsorption and calcium absorption).
Cardiovascular System
- The heart circulates blood, maintaining systemic circulation.
- This system delivers oxygen and nutrients to body tissues and organs.
Respiratory System
- Lungs facilitate oxygen delivery to tissues and carbon dioxide removal from the body.
Endocrine System
- The endocrine system regulates metabolism, growth, development, sleep, mood, sexual function, reproduction, stress response, and various other bodily functions, utilizing feedback mechanisms.
- Most endocrine mechanisms operate using negative feedback loops.
Reproductive System
- The reproductive system plays a role in creating offspring.
- Sex hormones influence bodily functions, such as muscle growth (testosterone) and bone growth (estrogen).
- Estrogen deficiency can impair bone development.
