Digestive system ✔️✔️comprised of the mouth stomach intestines. uses enzymes to break down foot
that we eat to release it into bloodstream and absorbed into cells. rids body of undigested food that
don't enter bloodstream in stool.
What is the main function of the alveoli in the lungs?
✔️✔️ The alveoli are responsible for gas exchange, allowing oxygen to enter the blood and carbon
dioxide to be removed.
Which part of the heart is responsible for pumping oxygenated blood to the body?
✔️✔️ The left ventricle pumps oxygenated blood to the body through the aorta.
What type of muscle tissue is found in the heart?
✔️✔️ Cardiac muscle tissue, which is involuntary and striated.
How does the nervous system communicate with muscles to initiate movement?
✔️✔️ The nervous system sends electrical signals (action potentials) through neurons to stimulate
muscle contractions.
What organ is primarily responsible for filtering blood and forming urine?
✔️✔️ The kidneys filter blood and remove waste to form urine.
In which part of the body are red blood cells produced?
✔️✔️ Red blood cells are produced in the bone marrow.
What is the primary function of hemoglobin within red blood cells?
✔️✔️ Hemoglobin binds to oxygen in the lungs and carries it to tissues throughout the body.
,How do hormones travel from endocrine glands to target organs?
✔️✔️ Hormones are released into the bloodstream and carried to target organs.
What role does the pancreas play in regulating blood sugar levels?
✔️✔️ The pancreas releases insulin to lower blood sugar levels and glucagon to raise them.
Which structure in the digestive system absorbs most nutrients?
✔️✔️ The small intestine absorbs most nutrients from digested food.
What is the function of the myelin sheath around neurons?
✔️✔️ The myelin sheath insulates neurons, speeding up the transmission of nerve impulses.
Which type of blood vessel carries blood away from the heart?
✔️✔️ Arteries carry blood away from the heart.
What is the main purpose of the large intestine in digestion?
✔️✔️ The large intestine absorbs water and forms solid waste.
How do the ribs and diaphragm work together during inhalation?
✔️✔️ The diaphragm contracts and moves downward, while the ribs expand to increase lung volume,
drawing air in.
What is the purpose of the epiglottis?
✔️✔️ The epiglottis prevents food and liquid from entering the trachea during swallowing.
respiratory system ✔️✔️nose mouth trachea lungs. gas exchange and pH regulation. removes CO2
from blood and exchanges for O2
, circulatory system ✔️✔️made up of heart blood vessels lymphatics blood cells. internal transport, pH
maintenance temperature stability. delivers nutrition and oxygen to cells and carries waste products and
CO2 away from cells.
immune system ✔️✔️defense system protects from foreign substances or particles when exposed.
white blood cells and lymph nodes. maintains homeostasis.
excretory system ✔️✔️enables disposal of metabolic wastes, regulation of salt, fluids and electrolytes.
allows waste removal from bloodstream via liver kidneys and urinary bladder skin and lungs.
integumentary system ✔️✔️skin- protects organs. defense skin doesnt allow foreign bodies in. skin
makes vitamin D and assists in excretion.
musculoskeletal system ✔️✔️hips, spinal column, deltoids quadriceps. protects movement support
and shape. supports production of blood and serves as storage sites for some minerals. muscle allow
movement strength posture and heat production. muscles work together to move the body.
nervous system ✔️✔️brain spinal cord and nerves. integrates body function through nerves detects
stimuli secretes chemicals and electrical signals and controls other organ systems.
endocrine system ✔️✔️hypothalamus pituitary glands adrenal glands pancreas and gonads. Integrates
body through chemicals hormones. cells use hormones to communicate with each other. hormones are
needed to maintain homeostasis.
reproductive system ✔️✔️scrotum testes prostate gland vas degerens and penis (male) ovaries
fallopian tubes uterus cervix vagina (female) provides mechanisms for internal fertilization and
production of new offspring.
phylum chordata ✔️✔️1. urochordatea
2. cephalochordata
3. vertebrata (humans, fish, reptiles, amphibians, and mammals)
