FUNCTIONS OF EACH SYSTEM Flashcards
1) What are the functions of the Cardiovascular System?
1) Removal of Waste Products
The cardiovascular system helps eliminate waste products, such as carbon dioxide, through the lungs and kidneys.
2) Transport of Oxygen
The cardiovascular system carries oxygen from the lungs to the body’s tissues through the red blood cells.
3) Removal of Waste Products
The cardiovascular system helps eliminate waste products, such as carbon dioxide, through the lungs and kidneys.
4) Maintenance of Body Temperature
It regulates body temperature by directing blood flow to or away from the skin, depending on environmental conditions.
2) What are the functions of the Skeletal System?
1) Protection
The bones protect vital organs such as the brain, heart, lungs, and spinal cord.
2) Mineral Storage
Bones store minerals like calcium, which are important for proper functioning of various bodily processes.
3) Red Blood Cell Production
Within the bone marrow, red blood cells are produced, which are essential for oxygen transportation.
4) Movement
The skeletal system, along with muscles and joints, allows for movement and locomotion.
3) What are the functions of the Muscular System?
1) Facial Expressions
Facial muscles allow learners to convey emotions through various expressions such as smiling, frowning, or raising eyebrows.
2) Body Posture
The muscular system helps maintain body posture, keeping learners in an upright position and supporting their body weight.
3) Muscle Contractions
Muscles contract and generate the force needed to move body parts and perform various actions.
4) What are the functions of the Digestive System?
1) Breaks down food
The digestive system’s primary function is to break down food into smaller, absorbable molecules.
2) Removes Waste
The digestive system helps eliminate waste materials from the body through the process of defecation.
3) Absorption
It facilitates the absorption of nutrients, such as vitamins, minerals, and carbohydrates, into the bloodstream
5) What are the functions of the Reproductive System?
1) Fertilisation
It enables the fusion of a sperm and an egg, leading to the formation of a zygote and the initiation of pregnancy.
2) Hormone Production
Various hormones, such as estrogen and progesterone in females and testosterone in males, are synthesized and released by the reproductive system, regulating sexual development, behavior, and reproductive cycles.
3) Sexual Pleasure and Satisfaction
The reproductive system is involved in sexual stimulation and orgasm, contributing to feelings of pleasure and emotional bonding in individuals.
6) What are the functions of the Endocrine System?
1) Regulation of Metabolism
The endocrine system plays a key role in regulating the body’s metabolism by controlling the rate at which cells convert nutrients into energy.
2) Growth and Development
Hormonal signals from the endocrine system are crucial for growth and development, especially during childhood and adolescence.
3) Maintenance of Homeostasis
The endocrine system helps maintain a stable internal environment by regulating various bodily functions such as temperature, blood pressure, and fluid balance.
7) What are the functions of the Nervous System?
1) Responses
The nervous system coordinates the body’s response to stress or danger
2) The nervous system controls voluntary movements
Voluntary movements are those that we consciously control, such as moving our arms or legs
3) The nervous system regulates involuntary functions
Involuntary functions are those that occur automatically without conscious control, such as breathing or heart rate
4) Cognitive Abilities
Cognitive processes refer to activities such as thinking, memory, and problem-solving
